Some novel N-sulfonylphthalimides I [R = NPh2, N-piperidinyl, morpholino, etc.] were synthesized in good yields by condensation of anhydride phthalic with various sulfonamides in one step. These compounds were screened for their antibacterial activity against E. coli, S. aureus, Morganella morganii and Klebsiella pneumoniae. So it will benificial to test these mols. against other biotargets different of bacterial strains such as viruses, fungus and parasites. The mol. structure of I [R = 3,4-dihydro-1H-isoquinolin-2-yl] was obtained by X-ray diffraction on mono crystal. The crystal packing could be described as alternating layers in zigzag parallel to (100) plane along the c axis, which were connected together with C-H···O hydrogen bonds.

Results: In total, 5,336 patient records were screened; 2,442 with prediabetes/diabetes were considered; 1,509 patients who fulfilled all criteria were analyzed. Use of metformin, SGLT2i, sulfonylureas, DPP4i, pioglitazone, orlistat, and GLP1a was 85.35%, 74.95%, 68.32%, 60%, 39.16%, 9.08%, and 4.17%, resp. However, 365, 970, and 104 patients were on one of 4 concerned medications (Group-1; 24.18%), dual MDT (Group-2; 64.28%), and triple/quadruple MDT (Group-3; 6.89%). Metformin with SGLT2i was most commonly used dual MDT (94.12%). Anal. according to weight-loss quartiles from 558 patients showed 6.9 kg weight-loss in the highest quartile. People losing maximum weight were significantly younger; had higher use of metformin, SGLT2i, GLP1, orlistat, and lower pioglitazone use; greatest HbA1c reduction (-1.3 vs. -0.3; quartile-1 vs. quartile -4; P < 0.001); and significantly higher occurrence of HbA1c<5.7% (16.8% vs. 6.29%; quartile-1 vs. 4; P < 0.001). Patients in Group-3 had the highest baseline BMI and maximum weight loss with highest number of patients with HbA1c<5.7% (19.44% vs. 10.34%; Group-3 vs. Group-1; P < 0.001). Conclusion: Greater weight loss with HbA1c reduction along with a greater number of patients attaining HbA1c <5.7% highlights that MDT is the way forward to tackle diabesity in India.

The development of new approaches toward chemo- and regioselective functionalization of polycyclic aromatic hydrocarbon (PAH) scaffolds will provide opportunities for the synthesis of novel biol. active small mols. that exploit the high degree of lipophilicity imparted by the PAH unit. Herein, new synthetic method for C-X bond substitution that is speculated to operate via a N-centered radical (NCR) mechanism according to exptl. observations was reported. A series of PAH sulfonamides have been synthesized and their biol. activity has been evaluated against Gram-neg. and Gram-pos. bacterial strains (using a BacTiter-Glo assay) along with a series of mammalian cell lines (using CellTiter-Blue and CellTiter-Glo assays). The viability assays have resulted in the discovery of a number of bactericidal compounds that exhibit potency similar to other well-known antibacterials such as kanamycin and tetracycline, along with the discovery of a luciferase inhibitor. Addnl., the physicochem. and drug-likeness properties of the compounds were determined exptl. and using in silico approaches and the results are presented and discussed within.

Our group has previously shown that pharmacol. inhibition of FASN with orlistat decreases proliferation, promotes apoptosis, and reduces the metastatic spread of B16-F10 cells in exptl. models of melanoma. While most of the orlistat antitumor properties seem to be closely related to direct effects on malignant cells, its impact on the host immune system is still unknown. The effects of orlistat on the phenotype and activation status of infiltrating leukocytes in primary tumors and metastatic lymph nodes were assessed using a model of spontaneous melanoma metastasis (B16-F10 cells/C57BL/6 mice). Cells from the primary tumors and lymph nodes were mech. dissociated and immune cells phenotyped by flow cytometry. The expression of IL-12p35, IL-12p40, and inducible nitric oxide synthase (iNOS) was analyzed by qRT-PCR and production of nitrite (NO2-) evaluated in serum samples with the Griess method. Orlistat-treated mice exhibited a 25% reduction in the number of mediastinal lymph node metastases (mean 3.96 ± 0.78, 95% CI 3.63-4.28) compared to the controls (mean 5.7 ± 1.72; 95% CI 5.01-6.43). Taken together, these findings suggest that orlistat supports an antitumor response against exptl. melanomas by increasing CD80/CD81-pos. and IL-12-pos. DC populations, granzyme b/NKG2D-pos. NK populations, and perforin/granzyme b-pos. CD8 T lymphocytes as well as reducing Tregs counts within exptl. melanomas.

A small library of ninety four uridine antibiotic analogs was synthesized, under the Pilot Scale Library (PSL) Program of the NIH Roadmap initiative, from amine 2 and carboxylic acids 33 and 77 in solution-phase fashion. Diverse aldehyde, sulfonyl chloride, and carboxylic acid reactant sets were condensed to 2, leading after acid-mediated hydrolysis, to the targeted compounds 3-32 in good yields and high purity. Similarly, treatment of 33 with diverse amines and sulfonamides gave 34-75. The coupling of the amino terminus of D-phenylalanine Me ester to the free 5′-carboxylic acid moiety of 33 followed by sodium hydroxide treatment led to carboxylic acid analog 77. Hydrolysis of this material gave analog 78. The intermediate 77 served as the precursor for the preparation of novel dipeptidyl uridine analogs 79-99 through peptide coupling reactions to diverse amine reactants. None of the described compounds show significant anticancer or antimalarial activity. A number of samples exhibited a variety of promising inhibitory, agonist, antagonist, or activator properties with enzymes and receptors in primary screens supplied and reported through the NIH MLPCN program.

Shirai, Kohji; Tanaka, Michitaka; Fujita, Toru; Fujii, Yuka; Shimomasuda, Masatsugu; Sakai, Soichi; Samukawa, Yoshishige published the artcile< Safety of Excessive Visceral Fat Reduction with 52-Week Administration of Lipase Inhibitor Orlistat in Japanese Individuals: A Long Term Clinical Study>, Recommanded Product: (S)-(S)-1-((2S,3S)-3-Hexyl-4-oxooxetan-2-yl)tridecan-2-yl 2-formamido-4-methylpentanoate, the main research area is orlistat lipase inhibitor visceral fat antiobesity agent; Body weight; Efficacy; Japanese; Lipase inhibitor; Long-term administration; Obesity; Orlistat; Safety; Visceral fat; Waist circumference.

Introduction: Orlistat is an inhibitor of pancreatic lipase and is used as an anti-obesity drug in many countries. However, there are no data available regarding the effects of orlistat on visceral fat (VF) accumulation in Japanese individuals. Therefore, this study aimed to analyze the efficacy and safety of 52 wk of orlistat administration in Japanese individuals. Methods: Orlistat 60 mg was administered orally three times daily for 52 wk to Japanese participants with excessive VF accumulation and without dyslipidemia, diabetes mellitus, and hypertension (metabolic diseases). Participants were also counseled to improve their diet and to maintain exercise habits. We defined excessive VF accumulation as a waist circumference (WC) of ≥ 85 cm for males and ≥ 90 cm for females, which corresponds to a VF area of 100 cm2. Adverse reactions, clin. laboratory tests, VF, WC, body weight (BW), etc., were monitored throughout the study period. Results: VF, WC, and BW were significantly reduced at week 52 from baseline; the mean ± standard error rate of change was – 21.52% ± 1.89%, – 4.89% ± 0.45%, and – 5.36% ± 0.56%, resp., and continued to reduce throughout the 52 wk; these significantly reduced at whole term compared with baseline. Most adverse reactions were defecation-related symptoms such as oily spotting and flatus with discharge (flatus with small amounts of stool or oil) due to the pharmacol. effects of the lipase inhibitor. These symptoms were mostly mild, reversible, and recognizable by the participants; none were serious or severe. No participants discontinued by medical judgment about adverse reactions, and the drug could be administered continuously. Conclusion: VF, WC, and BW were reduced from week 4 to week 52, indicating the effect of long-term orlistat administration. Moreover, it was well tolerated with an acceptable safety profile. Long-term administration of orlistat may be efficacious in reducing VF accumulation with safety when used in combination with diet and exercise. Trial Registration: This study is registered with the Japan Pharmaceutical Information Center (identifier: JapicCTI-184004). Funding: Funding for this study was provided by Taisho Pharmaceutical Co., Ltd.
