Abstract
Antimicrobial resistance threatens the efficacious prevention and treatment of infectious diseases caused by microorganisms. To combat microbial infections, the need for new drug candidates is essential. In this context, the design, synthesis, antimicrobial screening, and in silico study of a new series of 5-aryl-3-(2-arylthiazol-4-yl)isoxazole (9a-t) have been reported. The structure of new compounds was confirmed by spectrometric methods. Compounds 9a-t were evaluated for in vitro antitubercular and antimicrobial activity. Against M. tuberculosis H37Rv, fourteen compounds showed good to excellent antitubercular activity with MIC 2.01-9.80 µM. Compounds 9a, 9b, and 9r showed four-fold more activity than the reference drug isoniazid. Nine compounds, 9a, 9b, 9d, 9e, 9i, 9q, 9r, 9s, and 9t, showed good antibacterial activity against E. coli with MIC 7.8-15.62 µg/mL. Against A. niger, four compounds showed good activity with MIC 31.25 µg/mL. Against C. albicans, all twenty compounds reported excellent to good activity with MIC 7.8-31.25 µg/mL. Compounds 9c-e, 9g-j, and 9q-t showed comparable activity concerning the reference drug fluconazole. The compounds 9a-t were screened for cytotoxicity against 3t3l1 cell lines and found to be less or non-cytotoxic. The in silico study exposed that these compounds displayed high affinity towards the M. tuberculosis targets PanK, DprE1, DHFR, PknA, KasA, and Pks13, and C. albicans targets NMT, CYP51, and CS. The compound 9r was evaluated for structural dynamics and molecular dynamics simulations. The potent antitubercular and antimicrobial activity of 5-aryl-3-(2-arylthiazol-4-yl)isoxazole (9a-t) derivatives has recommended that these compounds could assist in treating microbial infections.Communicated by Ramaswamy H.

Abstract
A new series of 2-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-4-aryl thiazoles (10a-ab) have been synthesized by a cyclocondensation reaction of 5-aryl-1-phenyl-1H-pyrazole-3-carbothioamide (7a-d) with substituted phenacyl bromide (8a-f). The structure of newly synthesized 2-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-4-aryl thiazole (10a-ab) derivatives was characterized by spectroscopic analysis. The compounds 10a-ab were evaluated for in vitro antibacterial activity against Escherichia coli (NCIM 2574), Proteus mirabilis (NCIM 2388), Bacillus subtilis (NCIM 2063), Staphylococcus aureus (NCIM 2178), and in vitro antifungal activity against Aspergillus niger (ATCC 504) and Candida albicans (NCIM 3100). Among the twenty-eight pyrazolyl-thiazole derivatives, six compounds, 10g, 10h, 10i, 10j, 10o, and 10t, showed good activity against P. mirabilis; four compounds 10q, 10u, 10y, and 10z showed good activity against S. aureus; and twenty-four derivatives showed good antifungal activity against A. niger. Compounds 10g, 10q, 10r, 10s, and 10ab showed comparable activity with respect to the reference drug Ravuconazole. Thus, the significant antimicrobial activity of 2-(5-aryl-1-phenyl-1H-pyrazol-3-yl)-4-aryl thiazole (10a-ab) derivatives prompted that these scaffolds could assist in the development of lead compounds to treat microbial infections.

Abstract
Resistance to antibiotic drugs has directed global health security to a life-threatening situation due to mycobacterial infections. In search of a new potent antimycobacterial, a series of (±) 2-(6-substituted quinolin-4-yl)-1-alkoxypropan-2-ol (8a-p) have been synthesized. The structures of the newly synthesized derivatives were characterized by spectrometric analysis. Derivatives 8a-p were evaluated for antitubercular activity against Mycobacterium tuberculosis H37Rv (ATCC 25177), antibacterial activity against Proteus mirabilis (NCIM2388), Escherichia coli (NCIM 2065), Bacillus subtilis (NCIM2063) Staphylococcus albus (NCIM 2178) and antifungal activity against Candida albicans (NCIM 3100), Aspergillus niger (ATCC 504). Thirteen 2-(6-substituted quinolin-4-yl)-1-alkoxypropan-2-ol (8a-m) derivatives reported moderate to good antitubercular activity against M. tuberculosis H37Rv with MIC 9.2-106.4 μM. Compounds 8a and 8h showed comparable activity with respect to the standard drug pyrazinamide. The active compounds screened for cytotoxicity activity against L929 mouse fibroblast cells showed no significant cytotoxic activity. Compounds 8c, 8d, 8e, 8g, 8k, and 8o displayed good activity against S. albus. Compounds 8c and 8n showed good activity against P. mirabilis and E. coli, respectively. The potential antimycobacterial activities imposed that the 2-(6-substituted quinolin-4-yl)-1-alkoxypropan-2-ol derivatives could lead to compounds that could treat tuberculosis.

Abstract
Microbial infections remain a grave threat to global health security due to increasing antibiotic resistance. The coronavirus pandemic has increased the risk of microbial infection. To combat these infections, the search for new therapeutic agents is in high demand. A series of new 3-(2-(3-(substituted benzyloxy)oxetan-3-yl)-3-fluorophenoxy)-8-fluoro-2-methylquinoline (9a-i) derivatives have been synthesized. The structure of synthesized compounds was analyzed by spectroscopic methods. The newly synthesized oxetanyl-quinoline derivatives were evaluated for in vitro antibacterial activity against Escherichia coli (NCIM 2574), Proteus mirabilis (NCIM 2388), Bacillus subtilis (NCIM 2063), Staphylococcus albus (NCIM 2178), and in vitro antifungal activity against Aspergillus niger (ATCC 504) and Candida albicans (NCIM 3100). Six oxetanyl-quinoline derivatives 9a, 9b, 9c, 9d, 9e, and 9h have shown good antibacterial activity against P. mirabilis with MIC 31.25-62.5 μM, 3-(((3-(2-fluoro-6-((8-fluoro-2-methylquinolin-3-yl)oxy)phenyl)oxetan-3-yl)oxy)methyl)benzonitrile (9f) reporting comparable activity against P. mirabilis with respect to the standard drug streptomycin. Compound 9a also showed good activity against B. subtilis with MIC 31.25 μM. The eight compounds 9a, 9b, 9d, 9e, 9f, 9g, 9h, and 9i have shown good antifungal activity against A. niger. The synthesized compounds were also screened for antimycobacterial activity against Mycobacterium tuberculosis H37Rv by MTT assay. Among the nine derivatives, compounds 9b, 9c, 9d, 9f, 9g, 9h, and 9i showed excellent antimycobacterial activity with MIC 3.41-12.23 μM, and two derivatives showed good activity with MIC 27.29-57.73 μM. All the derivatives were further evaluated for cytotoxicity against the Vero cell line and were found to be nontoxic. The in silico study of compounds 9a-i was performed against ATP synthase (PDB ID: 4V1F) and most of the compounds showed the stable and significant binding to ATP synthase, confirming their plausible mode of action as ATP synthase inhibitors. Thus, the significant antimycobacterial activity of 3-(2-(3-(substituted benzyloxy)oxetan-3-yl)-3-fluorophenoxy)-8-fluoro-2-methylquinoline derivatives has suggested that the oxatenyl-quinoline compounds could assist in the development of lead compounds to treat mycobacterial infections.

Abstract
Abstract
Introduction
Majority of pharmacological agents used in the treatment of narcolepsy have several limitations. Both nonclinical and clinical evidences suggest usefulness of the histamine H3 receptor (H3R) inverse agonists for the treatment of narcolepsy and addressing several of the current limitations.
Methods
Extensive nonclinical studies were carried out for SUVN-G3031 and other pharmacological agents that are currently being used for the treatment of narcolepsy. Nonclinical parameters like inter-species binding affinity, selectivity profile, in vivo and in vitro ADME features, nonclinical efficacy, neurochemistry and safety were compared.
Results
SUVN-G3031 has no inter-species variation in binding affinity at H3R with less than 50% inhibition at 1 µM against 70 other targets. Unlike pitolisant, SUVN-G3031 has no significant binding affinity at sigma 1 and 2 receptor. SUVN-G3031 has no inhibition and induction liability towards major CYP enzymes and transporters. Pitolisant is reported to be a CYP3A4, CYP2B6, and CYP1A2 inducer and a CYP2D6 and OCT1 inhibitor. SUVN-G3031 has robust wake promoting effects. SUVN-G3031 showed negligible affinity towards hERG channel with IC50 > 10 µM and had no effects on any ECG parameters in dog telemetry study. SUVN-G3031 did not show convulsion in rats up to the tested dose of 100 mg/kg, p.o. Most of the pharmacological agents used for the treatment of narcolepsy have abuse liability; SUVN-G3031 produced no change in the striatal and accumbal dopamine levels in rats suggesting no propensity to induce abuse liability. Unlike competing H3R inverse agonists, SUVN-G3031 has no effects on fertility and embryo-fetal development up to the highest tested doses.
Conclusion
Nonclinical studies demonstrate superiority of SUVN-G3031 over pharmacological agents currently used in the treatment of narcolepsy.

Abstract
Abstract
Introduction
SUVN-G3031 is a potent inverse agonist at histamine H3 receptor (H3R) with selectivity over 70 other targets. SUVN-G3031 has excellent pharmacokinetics in rats and dogs. SUVN-G3031 demonstrated dose dependent receptor occupancy in rats with marked wake-promoting and anticataplectic effects in orexin knockout mice supporting its potential therapeutic utility in the treatment of narcolepsy. Long-term safety studies in animals and Phase 1 evaluation for safety, tolerability and pharmacokinetics demonstrated no concern for further development of SUVN-G3031.
Methods
SUVN-G3031 is currently being evaluated in a Phase 2 proof of concept study in USA for the treatment of narcolepsy with and without cataplexy (ClinicalTrials.gov Identifier: NCT04072380). This is a double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the safety, tolerability, pharmacokinetics and efficacy of SUVN-G3031 in comparison to placebo in patients with narcolepsy with and without cataplexy. Participants with an ESS score of ≥ 12; and mean MWT time of < 12 min are being randomized at a ratio of 1:1:1 to 2 mg SUVN-G3031, 4 mg SUVN-G3031 or placebo. Patients are to be stratified based on the type of narcolepsy. Each patient will receive study drug once daily for 14 days. The primary objective of the study is to evaluate the effectiveness of SUVN-G3031 compared to placebo as measured by an improvement in the maintenance of wakefulness test (MWT) score. Various secondary, exploratory, safety endpoints and steady state plasma concentrations will be evaluated.
Results
This study has been initiated in Q3 2019 and subject recruitment is expected to be completed by Q2 2020.
Conclusion
This study is a phase 2 clinical trial evaluating the efficacy and safety of SUVN-G3031 as a monotherapy in patients with narcolepsy with and without cataplexy. Safety and efficacy results from the study are expected in Q3 2020.

Abstract
Abstract
Introduction
Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, sleep paralysis, hallucinations, and in some cases episodes of cataplexy. Results from animal studies indicate the involvement of deficient orexin transmission in narcolepsy which can be circumvented by the activation of histaminergic neurons. SUVN-G3031 is a potent and selective histamine H3 receptor inverse agonist with hKi of 8.7 nM and shows less than 50% inhibition at 1 µM against 70 other targets. SUVN-G3031 exhibited excellent pharmacokinetic properties and brain penetration in preclinical species. Oral administration of SUVN-G3031 produces significant increase in histamine, dopamine and norepinephrine levels in the rat cortex. Long-term safety studies in animals have been successfully completed without any concern for further development of SUVN-G3031. In the present study, the effects of SUVN-G3031 were evaluated in orexin knockout mice, a reliable animal model of narcolepsy as a proof-of-concept study for the treatment of narcolepsy with and without cataplexy.
Methods
Male orexin knockout mice (10 - 15 weeks old, 25 - 35 g at the time of surgery) were implanted with telemetric device for simultaneous monitoring of electroencephalography (EEG) and electromyography. Animals were allowed surgical recovery of 3 weeks prior to EEG recording. Effects of SUVN-G3031 (3 and 10 mg/kg, p.o.) were evaluated during active period of animals.
Results
SUVN-G3031 produced significant increase in wakefulness with concomitant decrease in non-rapid eye movement sleep in orexin knockout mice. SUVN-G3031 also significantly decreased the number of cataplectic episodes in orexin knockout mice.
Conclusion
Results from the current preclinical study provide a strong basis for the utility of SUVN-G3031 for the treatment of narcolepsy with and without cataplexy. SUVN-G3031 is currently being evaluated in a Phase 2 study as monotherapy for the treatment of narcolepsy with and without cataplexy (ClinicalTrials.gov Identifier: NCT04072380).

Abstract
BACKGROUND Post-traumatic stress disorder is an anxiety disorder for which current therapies are not effective. The 5-Hydroxytryptamine6 receptor antagonist SB399885 has been reported to have an anxiolytic effect. Hence, the current investigation was undertaken to evaluate its efficacy in post-traumatic stress disorder. METHODS Rats were placed in the operant box and given 3 foot shocks at intervals of 1 min. The following day the duration of freezing was recorded. For the enhanced sustained prolonged stress (ESPS), the rats were subjected to various stressors such as restraint stress (2 h), forced swim (20 min), and anesthesia, followed by a foot shock for 4 s. The rats were then subjected to the elevated plus maze. RESULTS Treatment with SB399885 (1 and 3 mg/kg, I. p.) was found to significantly decrease the freezing time in the contextual fear conditioning model. Rats subjected to ESPS spent greater time in the open arm of the elevated plus maze when administered SB399885 at the above mentioned doses. The treatment had no effect on locomotor activity. SB399885 decreased the 5-hydroxytryptamine levels in the amygdala at doses that were effective in the above animal models. CONCLUSION 5-Hydroxytryptamine6 antagonists may hold potential in the treatment of post-traumatic stress.

Abstract
To assess the adverse drug reactions to non-steroidal anti-inflammatory drugs through spontaneous reporting system in IGGMC&H, Nagpur and to analyse them using WHO assessment scales, an observational, prospective study was conducted in patients attending outpatient department, inpatient department and casualty of IGGMC and H Nagpur from 1st June 2005 to 31st May 2009. Data were collected by spontaneous adverse drug reactions reporting system. Among 2639 total adverse drug reactions reported, 336 (12.7%) were due to non-steroidal anti-inflammatory drugs. The non-steroidal anti-inflammatory drugs most frequently implicated with adverse drug reactions were ibuprofen (51.19%) followed by diclofenac (27.08%), paracetamol (6.55%), nimesulide (6.25%), aspirin (5.95%). The most commonly affected organ systems were skin and appendages and gastro-intestinal system. Maculopapular rashes were the most frequent skin Involvement. Non-steroidal anti-inflammatory drugs are the most frequently used drugs. As they are commonly associated with adverse drug reactions, their limited and careful use is needed. Considering their prominent role in therapeutics, close clinical observations are very important in minimising adverse drug reactions and demands need for vigilant surveillance of adverse drug reactions in patients, receiving established as well as newer non-steroidal anti-inflammatory drugs.

Abstract
OBJECTIVE To integrate an immune-mediated mechanism and the disturbed protein expression in sporadic inclusion body myositis (IBM). BACKGROUND In IBM, abnormal fibers harbor inclusions of some proteins found in the brains of patients with Alzheimer disease (AD). Poly(A)-binding protein 1 (PABP1) is the RNA binding protein that attaches to the poly(A) tail of mRNA and is involved in translation and mRNA degradation. Under stresses, mRNA combined with PABP1 forms cytoplasmic granules called stress granules. METHODS Using 12 muscle biopsies with sporadic IBM and 46 controls, the authors localized PABP1 by immunohistochemistry, and poly(A)-containing RNA (poly(A)+ RNA) using the in situ hybridization method. They also immuno-localized HuR, one of the components of stress granules. RESULTS In IBM, a proportion of fibers, including those vacuolated, showed an abnormal accumulation of PABP1 immuno-positive deposits. An immunofluorescence study indicated that large PABP1 positive deposits formed conglomerates with poly(A)+ RNA and PABP1 colocalized with HuR. Although PABP1-positive cytoplasmic inclusions were found in disease controls, their aggregates combined with poly(A)+ RNA were only detected in IBM. CONCLUSIONS The localization of PABP1 positive deposits in inclusion body myositis (IBM) and other diseases may correspond to the stress granules that are formed under exposure to cellular stresses and the sites of mRNA turnover. The concomitant aggregation of poly(A)+ RNA that is specifically found in IBM may be due to the inhibition of mRNA degradation, which may affect translation. The authors speculate that an autoantibody against mRNA degradation machinery could play a role in this inhibition.

Abstract
OBJECTIVE To investigate alterations in protein kinases and phosphatases that regulate the activity of mitogen activated protein kinase (MAPK) in sporadic inclusion body myositis (IBM). BACKGROUND In vacuolated fibers in IBM, several studies reported upregulation of the extracellular regulated kinase (ERK) subclass of MAPK family. Whereas MAPK kinases (MKK) activate MAPK, MAPK phosphatases (MKP) inactivate MAPK. MKP-1 is involved in muscle fiber differentiation and it is downregulated during myotube formation. METHODS Immunolocalization of MKK1 through MKK4 and MKP-1 to MKP-3 was tested in muscle specimens from 10 patients with IBM and controls. RESULTS In IBM, strong and focal deposits of MKP-1 were observed in vacuolated fibers. The MKP-1-positive deposits were colocalized with ERK. MKP-2, MKP-3, and MKK were not associated with vacuolated fibers. CONCLUSIONS In IBM, MKP-1 is abnormally induced in vacuolated fibers probably to inactivate ERK. Although direct activators other than those tested in the current study might induce ERK, the absence of activation of MKK suggests that the aggregation of ERK protein itself causes the seeming upregulation of the protein kinase in IBM. Like ERK and its nuclear substrate, MKP-1 is an enzyme that forms aggregates in vacuolated fibers and is involved in myogenesis.

Abstract
We here reported a 54-year-old female patient with Crow-Fukase syndrome associated with pulmonary plasmacytoma. She was found to have scattered tumor in 1990. Although the tumor had slowly grown for the last 10 years, she showed no clinical symptoms. Numbness and weakness of lower extremities began in June 1999, and she was referred to Kyoto University Hospital on Oct. 21 1999 for evaluation of progressive symptoms. She had skin pigmentation, edema of the lower extremities, lymphadenopathy, muscle weakness and sensory disturbance in a glove-and-stocking distribution. Serological examination showed monoclonal IgG-lambda gammopathy. Serum vascular endothelial growth factor (VEGF) was markedly elevated. Microscopic studies on biopsied sural nerve demonstrated mild decrease of myelinated fibers. Immunohistochemically, the pulmonary tumor was defined as an IgG (lambda type) plasmacytoma. After treatment with melphalan-prednisolone therapy, the neurological symptoms improved along with decrease of serum VEGF levels as well as the size of pulmonary plasmacytoma. This is the first report of a patient with Crow-Fukase syndrome associated with pulmonary plasmacytoma. This case suggests that growth of pulmonary plasmacytoma might have played an important role in the overproduction of VEGF and thus development of Crow-Fukase syndrome.

Abstract
OBJECTIVE To assess abnormal intracellular signal transduction in inclusion body myositis (IBM). BACKGROUND Mitogen-activated protein kinases (MAPKs) play pivotal roles in intracellular signal transduction and regulate cell growth and differentiation. Upon their activation, MAPKs translocate from the cytoplasm into the nucleus. DESIGN/METHODS The authors investigated the localization of several forms of the MAPK family-extracellular signal-regulated kinase (ERK), c-Jun N-terminal protein kinase (JNK), and p38 MAPK (p38)-in 10 patients with sporadic IBM and in 52 control subjects. The relationship between the localization of immunopositive deposits and nuclei was tested with bis-benzimide. RESULTS Vacuolated fibers in IBM displayed very strong focal immunoreactivity of ERK, but not of JNK or p38. The ERK-positive deposits in these vacuolated fibers colocalized with the nuclear substrate of ERK, Elk-1. ERK- and Elk-1-positive deposits were located frequently on the surface of the nuclei in vacuolated fibers in IBM. Similar findings to those of sporadic IBM were observed in three patients with distal myopathy with rimmed vacuoles, but not in eight normal or the other 41 disease controls. CONCLUSION There is evidence for impaired molecular transport to the nucleus from the cytoplasm in the vacuolated fibers in IBM. This could be due to cytoplasmic aggregation of ERK and Elk-1 or to abnormal nuclear pore machinery involved in the transport of ERK and its substrate upon ERK activation.

Abstract
Cytochrome P4501B1 (CYP1B1) is involved in the activation of many carcinogens and in the metabolism of steroid hormones, including 17beta-oestradiol (E2) and testosterone. We report a significant difference in the allele frequencies of two point mutations in the coding region of the CYP1B1 gene among Caucasian (n = 189), African-American (n = 52) and Chinese (Linxian) (n = 109) populations. A (C to G) transversion at position 1666 in exon 3, which results in an amino acid substitution of Leu432 to Val, was present in African-Americans with an allele frequency for Va1432 of 0.75, in Caucasians of 0.43, and in Chinese of 0.17. A (C to T) transition at position 1719 in exon 3, with no amino acid change (Asp449), appeared to be closely linked with the Val432 variant. Results using human lung microsomal preparations from individuals with the CYP1B1Val/Val and CYP1B1Leu/Leu genotypes indicate that Val432 variant may be a high activity allele and thus may contribute to the interindividual differences in CYP1B1 activity. Because CYP1B1 is involved in hormone and carcinogen metabolism, and given the disparate rates of prostate cancer among ethnic groups, we also evaluated the association of the CYP1B1 Leu432Val polymorphism with prostate cancer risk in a pilot case-control study. Among Caucasians, 34% of men with cancer (n = 50) were homozygous for the Val432 polymorphism, while only 12% of matched control subjects (n = 50) had this genotype. These preliminary data indicate that genetic polymorphisms in CYP1B1 might play an important role in human prostate carcinogenesis.

Abstract
A patient of MELAS is reported. A 28-year-old woman was admitted to Shimada Municipal Hospital because of nausea, vomiting, and right homonymous hemianopsia. She had past history of dizziness and convulsion. A brain magnetic resonance imaging showed an ischemic lesion in the left occipital lobe, which disappeared in the follow-up study. Laboratory examination indicated elevated lactate and pyruvate levels in both blood and cerebrospinal fluid. The muscle biopsy demonstrated ragged-red fibers and strongly SDH-reactive blood vessels. PCR-RFLP analysis of DNA extracted from her muscle and blood as well as her mother's blood revealed a T to C mutation at nucleophile position of 3271 in mitochondrial DNA. She was diagnosed as having MELAS and discharged. One year after the first admission, she re-visited our hospital because of three days' duration of fatigability and generalized muscle pain after alcohol intake. She had severe lactic acidosis, rhabdomyolysis and acute renal failure. Despite a continuous hemodialysis and other intensive efforts, the patient died 20 hours later. Alcohol intake has been reported to induce rhabdomyolysis in myopathy with mitochondrial DNA deletions. The course of this patient suggests that alcohol intake can be an aggravating factor also in MELAS.

Abstract
1. Prenatal stress in rats has been shown to produce long-term behavioral, neuroendocrine and neurochemical changes. These changes may model aspects of human depressive illness. 2. In this pilot investigation, adult male offspring exposed to stress in utero and non-stressed controls were studied using 24-hour electroencephalographic sleep recordings. 3. Prenatally stressed animals demonstrated reduced latency to the onset of rapid eye movement (REM) sleep, prolongation of the first REM episode, and diminished slow-wave sleep. 4. Although preliminary, the observed changes parallel those seen in studies of human depression. These data further support the face validity of the prenatal stress model as a potential tool for future studies on the pathophysiology of depressive disorder.
