Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

An olefinic difunctionalization method of enones was presented hereviaaerobic visible-light catalysis. A novel reactivity was showcased in conjunction with the selective Csp(2)-C(CO) bond activation of enones, which provided a convenient method for the preparation of various beta-thiolated-alpha-functionalized compounds. Moreover, the preliminary investigation of the mechanism indicated that a beta-peroxysulfide intermediate was formed under the promotion of visible light under an oxygen atmosphere, which finally induced the unexpected C-C bond cleavage.

The highly selective C = C reduction of alpha,beta-enones was realized by CF3SO3H-modifying noble-metal-free TiO2 photocatalysis. Selectivity for C = C over C = O reduction was dramatically reversed from fair (similar to 42% without CF3SO3H-modifying) to excellent (> 99%) upon only 6 mol% CF3SO3H loading without any noble-metal additive. Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and C-13-nuclear magnetic resonance (NMR) demonstrated that CF3SO3H modification results in the alpha,beta-enone polar C = O bond sitting away from rather than near to the active sites of polar TiO2 catalysts.

The present study was planned to apply the nanotechnology to therapeutically proven flavonoid-rich fraction for obtaining a formulation with enhanced antihyperglycemic activity. The leaves were extracted in aqueous methanol and fractionated to yield a flavonoid-rich fraction. This fraction was formulated into an aqueous nanosuspension using PVA through the nanoprecipitation method. The developed formulations were characterized for physical parameters and optimum nanosuspension was evaluated against type 2 diabetes in high-fat diet-fed, streptozotocin-induced diabetic animals. The pharmacokinetic parameter and histopathology were assessed to determine the kinetic profile and tissue architectures post oral administration of selected nano suspension. The selected nanosuspension was also studied for stability under accelerated conditions. Flavonoidrich fraction was obtained using Kupchan partitioning. The developed nanosuspension PG-EA-NS-B showed optimum physical parameters. In hyperglycemia induced by streptozotocin, in high-fat diet-fed rats, it effectively restores the normal level of blood glucose in the first hour. The effects were comparable to standard Glibenclamide. In biochemical observations, PG-EA-NS-B, as well as PG-EA, showed beneficial effects on various hepatic and renal parameters. The pharmacokinetic parameters showed that nanosuspension enhances the absorption and decreases the metabolism of flavonoid actives. The selected nanosuspension and free flavonoid fraction showed rectification of histological changes. The nanosuspension was most stable in cool conditions. PVA based nanosuspensions can be a viable strategy for oral delivery of natural flavonoids, as it significantly affected the absorption and metabolism of flavonoids upon oral administration.

In the present work, coumarin based pyrazolines (7a-g) have been synthesized and investigated for their in vitro and in vivo anti-inflammatory potential. Amongst the synthesized compounds, compounds 7a, 7d and 7f exhibited significant in vitro anti-inflammatory activity as compared to the standard etoricoxib. Keeping this in mind, in vivo investigations were carried out via carrageenan induced inflammation and acetic acid induced writhing models in male Wistar rats and compound 7a was found to possess appreciable anti-inflammatory and analgesic potential. The mode of action of compound 7a was also investigated by using substance P as the biomarker, which shows promising results. Further, the selectivity of the most active compound 7a against the cyclooxygenase enzyme was supported by molecular docking studies which reveal that compound 7a has greater binding affinity towards COX-2 over COX-1 and 5-LOX enzymes. In silico ADME analysis of compound 7a confirms the drug-like characteristics and the in vivo acute toxicity study showed the safety of the compound even up to a 2000 mg kg(-1) dose. Thus, compound 7a was identified as an effective anti-inflammatory agent, and can be explored for further analgesic/anti-inflammatory drug design and development.

The use of the unprecedented annulating reagents methyl N-(tert-butylsulfinyl)-4-chlorobutanimidate and methyl N-(tert-butylsulfinyl)-5-bromopentanimidate enables the diastereoselective preparation of 5- and 6-membered carbocycles bearing three contiguous stereocenters. These synthons undergo cycloaddition with a variety of Michael acceptors to form cyclopentane/cyclohexane rings with excellent stereochemical control, generating only one of the eight possible diastereomers. This novel methodology has enabled the highly enantioselective and high yielding synthesis of novel chemotypes of pharmacological relevance.

In many metal catalyses, the traditional strategy of removing chloride ions is to add silver salts via anion exchange to obtain highly active catalysts. Herein, we reported an alternative strategy of removing chloride anions from ruthenium trichloride using an organic [P+-N-] zwitterionic compound via multiple hydrogen bond interactions. The resultant organic-metal hybrid catalytic system has successfully been applied to the aerobic oxidation of alcohols, tetrahydroquinolines, and indolines under mild conditions. The performance of zwitterion is far superior to that of many other common Lewis bases or Bronsted bases. Mechanistic studies revealed that the zwitterion triggers the dissociation of chloride from ruthenium trichloride via nonclassical hydrogen bond interaction. Preliminary studies show that the zwitterion is applicable to catalytic transfer semi-hydrogenation.

The synthesis of chiral unsaturated gamma-lactams is reported featuring a highly enantioselective palladium-catalyzed asymmetric allylic alkylation of alpha,gamma-disubstituted 2-silyloxypyrroles. This method allows a straightforward access to optically active gamma-lactams bearing an alpha-quaternary stereogenic center in high yields (up to 93%), high regioselectivities (up to >20:1), and excellent enantioselectivities (up to 95% ee). To further demonstrate the synthetic utility of the method, the resulting allylated products were converted to various versatile chiral building blocks, such as pyrrolidines and pyrrolidinones.
