Abstract
We present the first search for the pair production of dark particles X via K_{L}^{0}→XX with X decaying into two photons using the data collected by the KOTO experiment. No signal was observed in the mass range of 40-110 MeV/c^{2} and 210-240 MeV/c^{2}. This sets upper limits on the branching fractions as B(K_{L}^{0}→XX)<(1-4)×10^{-7} and B(K_{L}^{0}→XX)<(1-2)×10^{-6} at the 90% confidence level for the two mass regions, respectively.

Abstract
The nitrogen rule in mass spectrometry was used to search for new nitrogen-compounds from microbial metabolites. During this program, two new nitrogen-containing compounds, penicidones E and F, were discovered from the filamentous fungal strain FKI-7498, which was isolated from soil collected in Tokushima, Japan, and identified as Oidiodendron sp. by sequence analysis of the internal transcribed spacer region, including 5.8S ribosomal RNA. The structures of penicidones E and F were determined by mass spectrometry, nuclear magnetic resonance spectroscopy, and chemical modification analyses. These analyses revealed that penicidones E and F have a core structure of 3,5-dihydroxy-2-(4-pyridone-3-carbonyl)benzoic acid. Penicidone E exhibited hydroxyl radical scavenging activity.

Abstract
Plasmodium falciparum contains several mitochondrial electron transport chain (ETC) dehydrogenases shuttling electrons from the respective substrates to the ubiquinone pool, from which electrons are consecutively transferred to complex III, complex IV, and finally to the molecular oxygen. The antimalarial drug atovaquone inhibits complex III and validates this parasite’s ETC as an attractive target for chemotherapy. Among the ETC dehydrogenases from P. falciparum, dihydroorotate dehydrogenase, an essential enzyme used in de novo pyrimidine biosynthesis, and complex III are the two enzymes that have been characterized and validated as drug targets in the blood-stage parasite, while complex II has been shown to be essential for parasite survival in the mosquito stage; therefore, these enzymes and complex II are considered candidate drug targets for blocking parasite transmission. In this study, we identified siccanin as the first (to our knowledge) nanomolar inhibitor of the P. falciparum complex II. Moreover, we demonstrated that siccanin also inhibits complex III in the low-micromolar range. Siccanin did not inhibit the corresponding complexes from mammalian mitochondria even at high concentrations. Siccanin inhibited the growth of P. falciparum with IC50 of 8.4 μM. However, the growth inhibition of the P. falciparum blood stage did not correlate with ETC inhibition, as demonstrated by lack of resistance to siccanin in the yDHODH-3D7 (EC50 = 10.26 μM) and Dd2-ELQ300 strains (EC50 = 18.70 μM), suggesting a third mechanism of action that is unrelated to mitochondrial ETC inhibition. Hence, siccanin has at least a dual mechanism of action, being the first potent and selective inhibitor of P. falciparum complexes II and III over mammalian enzymes and so is a potential candidate for the development of a new class of antimalarial drugs.

Abstract
Sattahipmycin was isolated from the mycelium of marine-derived Streptomyces sp. GKU 257-1 by following the antibiofilm activity against E. coli NBRC 3972 throughout the purification steps. The structure of sattahipmycin was determined to be a new polycyclic xanthone related to xantholipin but lacking a dioxymethylene and a chlorinated carbon. This compound showed activity toward Gram-positive bacteria and Plasmodium falciparum, antibiofilm formation of Escherichia coli, and cytotoxicity to human cancer cell lines. Using genome sequence data, a biosynthetic pathway leading to sattahipmycin has been proposed involving an uncharacterized type II polyketide synthase biosynthetic gene cluster.

Abstract
Microorganisms in nature are highly diverse biological resources, which can be explored for drug discovery. Some countries including Brazil, Columbia, Indonesia, China, and Mexico, which are blessed with geographical uniqueness with diverse climates and display remarkable megabiodiversity, potentially provide microorganismal resources for such exploitation. In this review, as an example of drug discovery campaigns against tropical parasitic diseases utilizing microorganisms from such a megabiodiversity country, we summarize our past and on-going activities toward discovery of new antimalarials. The program was held in a bilateral collaboration between multiple Indonesian and Japanese research groups. In order to develop a new platform of drug discovery utilizing Indonesian bioresources under an international collaborative scheme, we aimed at: 1) establishment of an Indonesian microbial depository, 2) development of robust enzyme-based and cell-based screening systems, and 3) technology transfer necessary for screening, purification, and identification of antimalarial compounds from microbial culture broths. We collected, characterized, and deposited Indonesian microbes. We morphologically and genetically characterized fungi and actinomycetes strains isolated from 5 different locations representing 3 Indonesian geographical areas, and validated genetic diversity of microbes. Enzyme-based screening was developed against two validated mitochondrial enzymes from Plasmodium falciparum, dihydroorotate dehydrogenase and malate:quinone oxidoreductase, while cell-based proliferation assay was developed using the erythrocytic stage parasite of 3D7 strain. More than 17 thousands microbial culture extracts were subjected to the enzyme- and cell-based screening. Representative anti-malarial compounds discovered in this campaign are discussed, including a few isolated compounds that have been identified for the first time as anti-malarial compounds. Our antimalarial discovery campaign validated the Indonesian microbial library as a powerful resource for drug discovery. We also discuss critical needs for selection criteria for hits at each stage of screening and hit deconvolution such as preliminary extraction test for the initial profiling of the active compounds and dereplication techniques to minimize repetitive discovery of known compounds.

Abstract
Two new tetramic acid derivatives, traminines A (1) and B (2), were isolated from a culture broth of Fusarium concentricum FKI-7550 by bioassay-guided fractionation using multidrug-sensitive Saccharomyces cerevisiae 12geneΔ0HSR-iERG6. The chemical structures of 1 and 2 were elucidated by NMR studies. Compounds 1 and 2 inhibited the growth of the multidrug-sensitive yeast strain on nonfermentable medium containing glycerol, but not on fermentable medium containing glucose. These results strongly suggest that they target mitochondrial machineries presiding over ATP production via oxidative phosphorylation. Throughout the assay monitoring overall ADP-uptake/ATP-release in yeast mitochondria, 1 and 2 were shown to inhibit one or more enzymes involving oxidative phosphorylation. Based on biochemical characterization, we found that the interference with oxidative phosphorylation by 1 is attributable to the dual inhibition of complex III and FoF1-ATPase, whereas that by 2 is solely due to the inhibition of complex III.

Abstract
Two Indonesian fungi Aspergillus assiutensis BioMCC-f.T.7495 and Penicillium pedernalense BioMCC-f.T.5350 along with a Japanese fungus Hypomyces pseudocorticiicola FKI-9008 have been found to produce gentisyl alcohol (1), which inhibits Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 value of 3.4 μM. Another Indonesian fungus, Penicillium citrinum BioMCC-f.T.6730, produced an analog of 1, homogentisic acid (4), which also inhibits PfDHODH with an IC50 value of 47.6 μM.

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
Coenzyme A (CoA) is a well-known cofactor that plays an essential role in many metabolic reactions in all organisms. In Plasmodium falciparum, the most deadly among Plasmodium species that cause malaria, CoA and its biosynthetic pathway have been proven to be indispensable. The first and rate-limiting reaction in the CoA biosynthetic pathway is catalyzed by two putative pantothenate kinases (PfPanK1 and 2) in this parasite. Here we produced, purified, and biochemically characterized recombinant PfPanK1 for the first time. PfPanK1 showed activity using pantetheine besides pantothenate, as the primary substrate, indicating that CoA biosynthesis in the blood stage of P. falciparum can bypass pantothenate. We further developed a robust and reliable screening system to identify inhibitors using recombinant PfPanK1 and identified four PfPanK inhibitors from natural compounds.

Abstract
Antibiotics are microbial secondary metabolites and they are important for the treatment of infectious diseases. Japanese researchers have made a large contribution to studies of antibiotics, and they have also been important in the discovery of antiparasitic antibiotics. Satoshi Ōmura received the Nobel Prize in 2015 for the "discoveries concerning a novel therapy against infections caused by roundworm parasites", which means discovery of a new nematocidal antibiotic, avermectin. Here, I review the many antiparasitic antibiotics and their lead compounds that have been discovered for use in human and veterinary medicine.

Abstract
TanSat is the 1st Chinese carbon dioxide (CO2) measurement satellite, launched in 2016. In this study, the University of Leicester Full Physics (UoL-FP) algorithm is implemented for TanSat nadir mode XCO2 retrievals. We develop a spectrum correction method to reduce the retrieval errors by the online fitting of an 8th order Fourier series. The spectrum-correction model and its a priori parameters are developed by analyzing the solar calibration measurement. This correction provides a significant improvement to the O2 A band retrieval. Accordingly, we extend the previous TanSat single CO2 weak band retrieval to a combined O2 A and CO2 weak band retrieval. A Genetic Algorithm (GA) has been applied to determine the threshold values of post-screening filters. In total, 18.3% of the retrieved data is identified as high quality compared to the original measurements. The same quality control parameters have been used in a footprint independent multiple linear regression bias correction due to the strong correlation with the XCO2 retrieval error. Twenty sites of the Total Column Carbon Observing Network (TCCON) have been selected to validate our new approach for the TanSat XCO2 retrieval. We show that our new approach produces a significant improvement on the XCO2 retrieval accuracy and precision when compared to TCCON with an average bias and RMSE of -0.08 ppm and 1.47 ppm, respectively. The methods used in this study can help to improve the XCO2 retrieval from TanSat and subsequently the Level-2 data production, and hence will be applied in the TanSat operational XCO2 processing.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bencha-loga-wichian (BLW), a Thai traditional antipyretic formulation, has been reported to have promising antiplasmodial activity, and it was previously revealed that tiliacorinine and yanangcorinine, isolated from Tiliacora triandra, were the active compounds. However, the mechanisms of action of BLW have not been investigated. In addition, these active compounds are bisbenzylisoquinoline alkaloids, many compounds of which have been reported to potentiate the efficacy of chloroquine. AIMS OF THE STUDY To investigate the antiplasmodial mechanisms of action of BLW and evaluate the effects of chloroquine combined with tiliacorinine or yanangcorinine. MATERIALS AND METHODS Chloroquine-resistant Plasmodium falciparum (PfW2) strains at the ring, trophozoite, and schizont stages were exposed to the extracts or compounds for 2, 4, 6, 8, 10, 12, 24 or 48 h. The percentages of parasitemia were determined by flow cytometry, and their morphologies were examined by Giemsa-stained smear to evaluate the speed of action and stage specificity. For the drug combination assay, a modified fixed-ratio isobologram method was used. RESULTS The antiplasmodial activity of BLW possessed a slow onset of action and was the most effective against ring-stage parasites. After 48 h of extracts or compounds exposure, most of the treated parasites, at all stages, turned to the pyknotic form and could not recover even after extracts or compounds removal. The results suggested that these extracts and compounds could kill the parasites or possess parasiticidal effects. In addition, the combination of chloroquine with tiliacorinine or yanangcorinine demonstrated a synergistic effect, indicating that these compounds could potentiate chloroquine efficacy against chloroquine-resistant parasites. CONCLUSION The antiplasmodial mechanisms of action of BLW appeared to differ from that of chloroquine and other current antimalarial drugs. In addition, tiliacorinine and yanangcorinine, the active compounds of BLW, could potentiate the efficacy of chloroquine. Accordingly, BLW was shown to be a good candidate for development as a new antimalarial and useful for drug combination therapy.

Abstract
An Indonesian soil fungus, Talaromyces pinophilus BioMCC-f.T.3979 was cultured to find novel scaffolds of Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) inhibitors. We obtained altenusin (1), which inhibits PfDHODH, with an IC50 value of 5.9 μM, along with other metabolites: mitorubrinol (2) and mitorubrinic acid (3). Compounds 1 and 2 inhibited PfDHODH but displayed no activity against the human orthologue. They also inhibited P. falciparum 3D7 cell growth in vitro. Compound 3 showed little PfDHODH inhibitory activity or cell growth inhibitory activity.

Abstract
Basal stem rot (BSR), or Ganoderma rot disease, is the most serious disease associated with the oil palm plant of Southeast Asian countries. A basidiomycetous fungus, Ganoderma boninense, is the causative microbe of this disease. To control BSR in oil palm plantations, biological control agents are gaining attention as a major alternative to chemical fungicides. In the course of searching for effective actinomycetes as potential biological control agents for BSR, Streptomyces palmae CMU-AB204T was isolated from oil palm rhizosphere soil collected on the campus of Chiang Mai University. The culture broth of this strain showed significant antimicrobial activities against several bacteria and phytopathogenic fungi including G. boninense. Antifungal and antibacterial compounds were isolated by antimicrobial activity-guided purification using chromatographic methods. Their structures were elucidated by spectroscopic techniques, including Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS), Ultraviolet (UV), and Infrared (IR) analyses. The current study isolated new phenyl alkenoic acids 1-6 and three known compounds, anguinomycin A (7), leptomycin A (8), and actinopyrone A (9) as antimicrobial agents. Compounds 1 and 2 displayed broad antifungal activity, though they did not show antibacterial activity. Compounds 3 and 4 revealed a strong antibacterial activity against both Gram-positive and Gram-negative bacteria including the phytopathogenic strain Xanthomonas campestris pv. oryzae. Compounds 7-9 displayed antifungal activity against Ganoderma. Thus, the antifungal compounds obtained in this study may play a role in protecting oil palm plants from Ganoderma infection with the strain S. palmae CMU-AB204T.

Abstract
A new nitrogen-containing compound, trichothioneic acid, was discovered from the metabolites of fungal strain FKI-7573 using a mass spectrometry screening method guided by odd number of molecular weights, which indicates compounds that contain an odd number of nitrogen atoms. Strain FKI-7573 was isolated from soil collected in Obihiro, Hokkaido, Japan, and identified as Trichoderma virens by a sequence analysis of the internal transcribed spacer region, including 5.8S ribosomal RNA. The structure of trichothioneic acid was determined by mass spectrometry, nuclear magnetic resonance spectroscopy, electronic circular dichroism spectra, and chemical degradation analyses. These analyses revealed that trichothioneic acid consists of heptelidic acid and l-ergothioneine, and contains three nitrogen atoms. Trichothioneic acid exhibited hydroxyl radical-scavenging and singlet oxygen-quenching activities.

Abstract
The skeletons of some classes of terpenoids are unusual in that they contain a larger number of Me groups (or their biosynthetic equivalents such as olefinic methylene groups, hydroxymethyl groups, aldehydes, or carboxylic acids and their derivatives) than provided by their oligoprenyl diphosphate precursor. This is sometimes the result of an oxidative ring-opening reaction at a terpene-cyclase-derived molecule containing the regular number of Me group equivalents, as observed for picrotoxan sesquiterpenes. In this study a sesquiterpene cyclase from Trichoderma spp. is described that can convert farnesyl diphosphate (FPP) directly via a remarkable skeletal rearrangement into trichobrasilenol, a new brasilane sesquiterpene with one additional Me group equivalent compared to FPP. A mechanistic hypothesis for the formation of the brasilane skeleton is supported by extensive isotopic labelling studies.

Abstract
Whole genome analysis of Streptomyces sp. KO-7888 has revealed various pathway-specific transcriptional regulatory genes associated with silent biosynthetic gene clusters. A Streptomyces antibiotic regulatory protein gene, speR, located adjacent to a novel nonribosomal peptide synthetase (NRPS) gene cluster, was overexpressed in the wild-type strain. The resulting recombinant strain of Streptomyces sp. KO-7888 produced two new lipopeptides, sarpeptins A and B. Their structures were elucidated by high-resolution electrospray ionization mass spectrometry, NMR analysis, and the advanced Marfey's method. The distinct modular sections of the corresponding NRPS biosynthetic gene cluster were characterized, and the assembly line for production of the lipopeptide chain was proposed.

Abstract
Kozupeptins A and B, novel antimalarial lipopeptides, were isolated from the culture broths of Paracamarosporium sp. FKI-7019. They exhibited potent antimalarial activity against chloroquine-sensitive and -resistant Plasmodium falciparum strains in vitro. The structural elucidation was accomplished by a combination of spectroscopic analyses and chemical approaches including a total synthesis of kozupeptin A. Synthetic kozupeptin A demonstrated a therapeutic effect in vivo, and an intermediate exhibited much higher antimalarial activity than kozupeptin A.

Abstract
A search for the rare decay K_{L}→π^{0}νν[over ¯] was performed. With the data collected in 2015, corresponding to 2.2×10^{19} protons on target, a single event sensitivity of (1.30±0.01_{stat}±0.14_{syst})×10^{-9} was achieved and no candidate events were observed. We set an upper limit of 3.0×10^{-9} for the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level (C.L.), which improved the previous limit by almost an order of magnitude. An upper limit for K_{L}→π^{0}X^{0} was also set as 2.4×10^{-9} at the 90% C.L., where X^{0} is an invisible boson with a mass of 135 MeV/c^{2}.

Abstract
Amebiasis is caused by infection with the protozoan parasite Entamoeba histolytica. Although metronidazole has been a drug of choice against amebiasis for decades, it shows side effects and low efficacy against asymptomatic cyst carriers. In addition, metronidazole resistance has been documented for bacteria and protozoa that share its targets, anaerobic energy metabolism. Therefore, drugs with new mode of action or targets are urgently needed. L-cysteine is the major thiol and an essential amino acid for proliferation and anti-oxidative defense of E. histolytica trophozoites. E. histolytica possesses the de novo L-cysteine biosynthetic pathway, consisting of two reactions catalyzed by serine acetyltransferase and cysteine synthase (CS, O-acetylserine sulfhydrylase). As the pathway is missing in humans, it is considered to be a rational drug target against amebiasis. In this study, we established a protocol to screen both a library of structurally known compounds and microbial culture extracts to discover compounds that target de novo cysteine biosynthesis of E. histolytica. The new screening system allowed us to identify the compounds that differentially affect the growth of the trophozoites in the cysteine-deprived medium compared to the cysteine-containing medium. A total of 431 structurally defined compounds of the Kitasato Natural Products Library and 6,900 microbial culture broth extracts were screened on the system described above. Five compounds, aspochalasin B, chaetoglobosin A, prochaetoglobosin III, cerulenin, and deoxyfrenolicin, from the Kitasato Natural Products Library, showed differential antiamebic activities in the cysteine-deprived medium when compared to the growth in the cysteine-containing medium. The selectivity of three cytochalasans apparently depends on their structural instability. Eleven microbial extracts showed selective antiamebic activities, and one fungal secondary metabolite, pencolide, was isolated. Pencolide showed cysteine deprivation-dependent antiamebic activity (7.6 times lower IC50 in the absence of cysteine than that in the presence of cysteine), although the IC50 value in the cysteine-deprived medium was rather high (283 μM). Pencolide also showed inhibitory activity against both CS1 and CS3 isoenzymes with comparable IC50 values (233 and 217 μM, respectively). These results indicated that antiamebic activity of pencolide is attributable to inhibition of CS. Cytotoxicity of pencolide was 6.7 times weaker against mammalian MRC-5 cell line than E. histotytica. Pencolide has the maleimide structure, which is easily attacked by Michael donors including the thiol moiety of cysteine. The cysteine-adducts of pencolide were detected by mass spectrometric analysis as predicted. As CS inhibition by the pencolide adducts was weak and their IC50 values to CS was comparable to that to the parasite in the cysteine-containing medium, the cysteine-adducts of pencolide likely contribute to toxicity of pencolide to the parasite in the cysteine-rich conditions. However, we cannot exclude a possibility that pencolide inactivates a variety of targets other than CSs in the absence of cysteine. Taken together, pencolide is the first compound that inhibits CS and amebic cell growth in a cysteine-dependent manner with relatively low mammalian cytotoxicity.

Abstract
The multidrug-sensitive budding yeast, Saccharomyces cerevisiae 12geneΔ0HSR-iERG6, is very useful in antifungal screens. A novel compound, named pestynol (1), was discovered from a culture of the fungus Pestalotiopsis humus FKI-7473 using the multidrug-sensitive yeast. The structure of 1 was elucidated by NMR studies and modified Mosher's method as (1 R,2 R,3 R,4 R)-( E)-5-(7,11-dimethyl-3-methylenedodeca-6,10-dien-1-yn-1-yl)cyclohex-5-ene-1,2,3,4-tetraol. Compound 1 showed antimicrobial activity against the Gram-positive bacteria, Klebsiella pneumoniae, and S. cerevisiae 12geneΔ0HSR-iERG6 and Mucor racemosus, but displayed only weak cytotoxicity against various human cancer cell lines. Compound 1 displayed antifungal activities against S. cerevisiae 12geneΔ0HSR-iERG6 and Mucor racemosus at 10 μg/disc.

Abstract
The Coenzyme A (CoA), as a cofactor involved in >100 metabolic reactions, is essential to the basic biochemistry of life. Here, we investigated the CoA biosynthetic pathway of Entamoeba histolytica (E. histolytica), an enteric protozoan parasite responsible for human amebiasis. We identified four key enzymes involved in the CoA pathway: pantothenate kinase (PanK, EC 2.7.1.33), bifunctional phosphopantothenate-cysteine ligase/decarboxylase (PPCS-PPCDC), phosphopantetheine adenylyltransferase (PPAT) and dephospho-CoA kinase (DPCK). Cytosolic enzyme PanK, was selected for further biochemical, genetic, and phylogenetic characterization. Since E. histolytica PanK (EhPanK) is physiologically important and sufficiently divergent from its human orthologs, this enzyme represents an attractive target for the development of novel anti-amebic chemotherapies. Epigenetic gene silencing of PanK resulted in a significant reduction of PanK activity, intracellular CoA concentrations, and growth retardation in vitro, reinforcing the importance of this gene in E. histolytica. Furthermore, we screened the Kitasato Natural Products Library for inhibitors of recombinant EhPanK, and identified 14 such compounds. One compound demonstrated moderate inhibition of PanK activity and cell growth at a low concentration, as well as differential toxicity towards E. histolytica and human cells.

Abstract
Reactive oxygen species (ROS) generated by reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox)1 mediate cellular signalings involved in normal physiological processes, and aberrant control of Nox1 has been implicated in the pathogenesis of various diseases. Therefore, Nox1 could have great potential as a therapeutic target. Here, we identified a novel Nox1 inhibitor, NOS31 secreted from Stretomyces sp. and analyzed its chemical structure. Furthermore, NOS31 was found to selectively inhibit Nox1-mediated ROS generation, with only a marginal effect on other Nox isoforms (Nox2-5) and no ROS scavenging activity. This compound blocked both Nox organizer 1 (NOXO1)/Nox activator 1 (NOXA1)-dependent and phorbol 12-myristate 13-acetate-stimulated Nox1-mediated ROS production in colon cancer cells. NOS31 inhibited the proliferation of several colon carcinoma and gastric cancer cell lines that upregulate the Nox1 system, whereas it had no appreciable effect on normal cells with low levels of Nox1. The finding suggests that NOS31 is a unique, potent Nox1 inhibitor of microbial origin and raises its possibility as a therapeutic agent for inhibiting gastrointestinal cancer cell growth.

Abstract
Plasmodium falciparum is an apicomplexan parasite that causes the most severe malaria in humans. Due to a lack of effective vaccines and emerging of drug resistance parasites, development of drugs with novel mechanisms of action and few side effects are imperative. To this end, ideal drug targets are those essential to parasite viability as well as absent in their mammalian hosts. The mitochondrial electron transport chain (ETC) of P. falciparum is one source of such potential targets because enzymes, such as L-malate:quinone oxidoreductase (PfMQO), in this pathway are absent humans. PfMQO catalyzes the oxidation of L-malate to oxaloacetate and the simultaneous reduction of ubiquinone to ubiquinol. It is a membrane protein, involved in three pathways (ETC, the tricarboxylic acid cycle and the fumarate cycle) and has been shown to be essential for parasite survival, at least, in the intra-erythrocytic asexual stage. These findings indicate that PfMQO would be a valuable drug target for development of antimalarial with novel mechanism of action. Up to this point in time, difficulty in producing active recombinant mitochondrial MQO has hampered biochemical characterization and targeted drug discovery with MQO. Here we report for the first time recombinant PfMQO overexpressed in bacterial membrane and the first biochemical study. Furthermore, about 113 compounds, consisting of ubiquinone binding site inhibitors and antiparasitic agents, were screened resulting in the discovery of ferulenol as a potent PfMQO inhibitor. Finally, ferulenol was shown to inhibit parasite growth and showed strong synergism in combination with atovaquone, a well-described anti-malarial and bc1 complex inhibitor.

Abstract
The ethanolic extract from the stem bark of Goniothalamus marcanii Craib was shown in preliminary brine shrimp lethality data having good cytotoxic activity. Further bioassay guided isolation was done by means of solvent partition, chromatography and precipitation to provide four isolated compounds: a novel compound 1 with the core structure of 1-azaanthraquinone moiety referred as marcanine G; as well as compounds 2-4 with known aristolactam structures namely, piperolactam C, cepharanone B and taliscanine. These compounds were characterised by spectroscopic techniques. The assessment of cytotoxicity was established on an SRB assay using doxorubicin as a positive control. Marcanine G (1) was considered the most active compound indicating the IC50 values of 14.87 and 15.18 μM against human lung cancer cells (A549) and human breast cancer cells (MCF7), respectively. However, 2 showed mild activity with the IC50 values of 83.72 and 82.32 μM against A549 and MCF7 cells, respectively.

Abstract
Microbial natural products possess a wide range of biological and biochemical potential. Among them, fungal secondary metabolites are one of the most important sources for discovering new drugs or lead compounds. In the present study, we explored substances produced by the strain Penicillium sp. FKI-7127 for its antiviral activity. We identified brefeldin A as a novel antiviral agent against dengue viruses. The inhibitory effect of brefeldin A was confirmed by virus titer and immunofluorescence assay. Brefeldin A inhibited dengue viruses regardless of serotypes and other related viruses including Zika virus and Japanese encephalitis virus. Time-of-addition study showed that brefeldin A exerts its antiviral effect at an early stage of the dengue virus (DENV) life cycle. These studies demonstrate that (i) brefeldin A could be used as a lead compound for drug development of anti-DENV and other related viruses and (ii) fungal metabolites are a potential and valuable source for dengue virus drug discovery.

Abstract
A new pyrrole compound, 1-methoxypyrrole-2-carboxamide, was obtained from a culture broth of Streptomyces griseocarneus SWW368, which was isolated from the rhizospheric soil under a Para rubber tree (Hevea brasiliensis). The chemical structure was elucidated by 1D NMR, 2D NMR, and MS, as a pyrrole ring with a N-methoxy group and a primary amide group. It exhibited antibacterial properties against Kocuria rhizophila, Staphylococcus aureus and Xanthomonas campestris pv. oryzae; however, cytotoxicity of the compound at 714 μM against several mammalian tumor cell lines, i.e. A549, PANC1, HT29, HT1299 and HeLa S3, were not detected.

Abstract
Nafuredin-γ, obtained from natural nafuredin, has demonstrated a potent and selective inhibitory activity against nematode complex I. However, nafuredin-γ is unstable in air since its conjugated dienes are oxygen-labile. The instability in air was naturally solved by the synthesis of structure-simplified nafuredin-γ analogs without conjugated dienes. However, these modified analogs showed lower complex I inhibitory activities. Therefore, new air-stable structure-simplified nafuredin-γ analogs were designed and synthesized herein. Among all analogs synthesized, the one bearing a unique 1-azabicyclo[3.1.0]hexane scaffold showed the highest inhibitory activity (IC50=170 nM) while presenting high selectivity against nematode complex I.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bencha-Loga-Wichian (BLW) is a polyherbal antipyretic formulation that is comprised of Capparis micracantha, Clerodendrum indicum, Ficus racemosa, Harrisonia perforata, and Tiliacora triandra. A traditional medical textbook has documented the use of this formulation for the treatment of many types of fever, including malaria-like fever. Traditionally, BLW is composed of the root parts of those plants. However, in current practice, the stem parts are frequently substituted. Thus, this study aimed to evaluate the antiplasmodial activities of BLW and compare the efficacy between the stem and root parts. MATERIALS AND METHODS BLW formulations produced from either the stem or root parts of the various constituent plants as well as the stems or roots of the individual plants were separately extracted and tested against the chloroquine-sensitive (Pf3D7) and -resistant (PfW2) strains Plasmodium falciparum using flow cytometry. The cytotoxicity against peripheral blood mononuclear cells was evaluated using the WST-8 assay to determine the selectivity index (SI). The active compounds of BLW were isolated using antiplasmodial-guided isolation and quantified using Ultra-Performance Liquid Chromatography (UPLC). RESULTS The stem and root parts of BLW and the individual plants exhibited antiplasmodial activities at the same levels with good SI values in the range of 3.55-19.74. The extracts of BLW exhibited promising antiplasmodial activity against both Pf3D7 (IC50<5µg/mL) and PfW2 (IC50=6-10µg/mL). Among the five component plants, T. triandra was the most active and exhibited an IC50<5µg/mL against both strains of parasites with SI values >10. We isolated tiliacorinine and yanangcorinine as the major active compounds (IC50<2µg/mL). However, these two compounds demonstrated cytotoxic effects (SI<1). The UPLC analysis identified these compounds in both the stem and root parts of BLW in the range of 0.57-7.66%, which correlated with the antiplasmodial activity. The concentrations of these compounds in BLW, at comparable efficacy, were much less than those at the IC50s for the single compounds alone. It suggested that synergistic interactions increased the antiplasmodial effects as well as alleviated the toxicity of the active compounds in BLW. CONCLUSION This study described a promising antiplasmodial activity of BLW that had good selectivity and a toxicity-alleviating effect. The results provided scientific support for the use of this formulation for the treatment of malaria. In addition, the stem and root parts of the plants in BLW exhibited equivalent activities, which indicates the potential for the substitution of the stem parts in the formulation. Thus, we recommend additional study of the stem parts of these plants for further development on the basis of the availability and sustainability.
