Abstract
Piper nigrum is a popular crop that can be used as seasoning or as an additive but its active ingredients also have an effect on the nervous system. Nineteen new amide alkaloids (1a/1b, 2-5, 6a/6b, 7, 8a/8b, 9, 10a/10b, 11a-11b, 12-14) were isolated from P. nigrum, guided by inhibitory activity of AChE and LC-MS/MS based on GNPS. The configurations were determined by extensive spectral analysis, Bulkiness rule, and NMR calculations. The inhibitory activities of AChE/BuChE and Aβ aggregation were tested, and the results showed compounds 2, 7, and 12 had significant inhibitory activities. These components were identified in the crude fraction and their relative quantities were tested, which suggested that compound 2 was the index component in the active site from P. nigrum.

Abstract
Marine actinomycetes are known for their production of remarkable organic molecules, particularly those featuring polyoxygenated long-chain backbones. Determining the absolute configurations of these compounds remains a challenging task even today. In this study, we successfully established the planar structures and absolute configurations of two highly flexible amide alkaloids from Streptomyces sp. WU20: kueishanamides A (1) and B (2). These compounds possess a C13 linear backbone and each contains five stereogenic carbon centers. Our approach involved a combination of spectroscopic and computational methods, including J-based configurational analysis and VCD calculations, ensuring the unambiguous determination of their configurations. Kueishanamide A (1) and kueishanamide B (2) showed moderate antifungal activity against pathogenic fungus Crytococcus neoformans, with MIC values of 25 μg/mL each.

Abstract
A new amide (1), two new phenylpropanoid derivatives (2, 3), along with three new natural products, including three nitrogen chirality compounds, N-(3-methoxy-1,3-dioxopropyl)-D-phenylalanine methyl ester (4), N-(3-methoxy-1,3-dioxopropyl)-L-phenylalanine methyl ester (5), and N-acetyl-L-phenylalanine methyl ester (6), as well as dimethyl (2R,3R)-2-hydroxy-3-(((E)-3-(4-hydroxyphenyl)acryloyl)oxy)succinate (7) and dimethyl (S,E)-2-((3-(4-hydroxy-3-methoxyphenyl)acryloyl)oxy)succinate (8) were isolated from Delphinium kamaonense Hunth. Their structures were elucidated by extensive analysis of 1D and 2D NMR, and HR-ESI-MS experiments, and the absolute configurations were determined by comparative analysis of specific optical rotation. Compound 1 exhibited a moderate cytotoxicity effect against Hep-3B cancer cell lines (IC50 41.39±0.13 μM) and an excellent antioxidant activity (IC50 0.527±0.06 μM in ABTS assay, and 1.235±0.09 μM in DPPH assay, respectively), which was superior to vitamin C in ABTS (IC50 1.670±0.07 μM) and DPPH (IC50 19.10±0.40 μM) methods.

Abstract
Bacterial communication, termed Quorum Sensing (QS), is a promising target for virulence attenuation and the treatment of bacterial infections. Infections cause inflammation, a process regulated by a number of cellular factors, including the transcription Nuclear Factor kappa B (NF-κB); this factor is found to be upregulated in many inflammatory diseases, including those induced by bacterial infection. In this study, we tested 32 synthetic derivatives of coumaperine (CP), a known natural compound found in pepper (Piper nigrum), for Quorum Sensing Inhibition (QSI) and NF-κB inhibitory activities. Of the compounds tested, seven were found to have high QSI activity, three inhibited bacterial growth and five inhibited NF-κB. In addition, some of the CP compounds were active in more than one test. For example, compounds CP-286, CP-215 and CP-158 were not cytotoxic, inhibited NF-κB activation and QS but did not show antibacterial activity. CP-154 inhibited QS, decreased NF-κB activation and inhibited bacterial growth. Our results indicate that these synthetic molecules may provide a basis for further development of novel therapeutic agents against bacterial infections.

Abstract
Tetradium trichotomum Lour., is a plant species endemic to tropical South East Asia with particular medicinal importance. However, very little analysis in this plant has been studied up to now from a phytochemical viewpoint. One new amide alkaloid (wuchuyuamide V, 1), as well as two known amide alkaloids-wuchuyuamide III (2), and wuchuyuamide I (3) were obtained from the fruits of T. trichotomum for the first time. The structures of wuchuyuamide V (1) and wuchuyuamide III (2) were unambiguously elucidated by 1D and 2D-NMR spectra, mass spectrometry, and single-crystal X-ray diffraction.

Abstract
Piperine, piperlonguminine and pellitorine are three major amide alkaloids from Piper longum, showing a variety of pharmacological activities. In order to investigate the different metabolism pathways of these compounds in five species of liver microsomes in vitro, the data of full mass spectrum, and MS2, MS3 spectra of these three alkaloids were collected and analyzed by using ultra-high-performance liquid chromatography coupled with a LTQ-orbitrap mass spectrometer (UHPLC-LTQ-Orbitrap MS); gragment ion information was collected and combined with fragmentation regularities of mass spectra and accurate mass spectrometry data of metabolites, to compare the metabolism difference of three amide alkaloids in liver microsomes of human, rhesus monkey, Beagle dogs, rats and mice. 3 metabolites of piperine, 2 metabolites of piperlonguminine and 1 metabolite of pellitorine were identified quickly. The results showed that the major metabolic pathways of these amide alkaloids in liver microsomes were methylenedioxy group demethylation and oxidation reaction, and metabolic rates were different between species. This study provides basis for further research on in vivo metabolism of piperine analogues from Piper longum.

Abstract
Three new amide alkaloids piperlongumamides A-C (1–3), together with 12 known ones (4–15), were isolated from the fruits of Piper longum. The structures of the new isolates were determined using spectroscopic data analyses. Cytotoxic activity of these amides against HL-60 (human leukemia), A-549 (human lung cancer), MCF-7 (human breast cancer), SMMC-7721 (human liver cancer) and SW480 (human rectal cancer) cell lines were evaluated. Piperchabamide B (11) exhibited weak inhibitory activity against HL-60 (IC50 = 21.32 μM ), A-549 (IC50 = 23.82 μM ) and MCF-7 (IC50 = 16.58 μM ) cell lines. ![]()
