The chalcone derivatives 3a-d reacted with either malononitrile or ethyl cyanoacetate in ethanol in the presence of catalytic amount of ammonium acetate in an oil bath at 120 degrees C to give the Knowevenagel condensation products 5a-h. The latter compounds reacted with hydrazine hydrate and afforded the 4H-pyrazole derivatives 7a-h, respectively. The reaction of compounds 7a-h with ethyl cyanoacetate in dimethylformamide under refluxing condition afforded the cyanoacetamido derivatives 8a-h, respectively. When compounds 8a-h reacted with elemental sulfur and either of malononitrile or ethyl cyanoacetate in ethanol containing triethylamine, the thiophene derivatives 9a-h and 10a-h, respectively, were obtained. The structure of the newly synthesized compounds was established by the analytical and spectral data. All the newly synthesized compounds were evaluated against the six cancer cell lines: A549, HT-29, MKN-45, U87MG, and SMMC-7721 and H460. Compounds 3c, 5h, 7g, 7h, 8f, 9e, 9g, and 10g were selected to examine their Pim-1 kinase inhibition activity as these compounds showed high inhibition toward the c-Met kinase and the tested cancer cell lines. Furthermore, compounds 3b, 3c, 5g, 5h, 7f, 7g, 7h, 8e, 8f, 8g, 8h, 9e, 9f, 9g, 9h, 10g and 10h were selected to be tested for pan-assay interference compounds analysis (PAINS). Almost all the tested compounds showed zero PAINS alert and can be used as drug compounds in the future.

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.

SDS of cas: 94-41-7. Authors Gaur, PK in ELSEVIER published article about in [Gaur, Praveen Kumar] ITS Coll Pharm, Dept Pharmaceut, Meerut Rd, Murad Nagar 201206, Ghaziabad, India in 2021.0, Cited 50.0. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7

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.

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.

In search for new molecular entities as anti-TB agents, the benzimidazoquinazoline polyheterocyclic scaffold has been designed adopting the scaffold hopping strategy. Thirty-two compounds have been synthesized through an improved tandem decarboxylative nucleophilic addition cyclocondensation reaction of o-phenylenediamine with isatoic anhydride followed by further cyclocondensation of the intermediately formed 2-(o-aminoaryl) benzimidazole with trialkyl orthoformate/acetate. The resultant benzimidazoquinazolines were evaluated in vitro for anti-TB activity against M. tuberculosis H37Rv (ATCC27294 strain). Fourteen compounds exhibiting MIC values in the range of 0.4-6.25 mu g/mL were subjected to cell viability test against RAW 264.7 cell lines and were found to be non-toxic (< 30% inhibition at 50 mu g/mL). The active compounds were further evaluated against INH resistant Mtb strains. The most active compound 6x [MIC (H37Rv) of 0.4 mu g/mL] and the compound 6d [MIC (H37Rv) of 0.78 mu g/mL] were also found to be active against INH resistant Mtb strain with MIC values of 12.5 and 0.78 mu g/mL, respectively.
