- Investigating 3,3-diaryloxetanes as potential bioisosteres through matched molecular pair analysis
-
Oxetanes have received increasing interest in medicinal chemistry as attractive polar and low molecular weight motifs. The application of oxetanes as replacements for methylene, methyl,gem-dimethyl and carbonyl groups has been demonstrated to often improve chemical properties of target molecules for drug discovery purposes. The investigation of the properties of 3,3-diaryloxetanes, particularly of interest as a benzophenone replacement, remains largely unexplored. With recent synthetic advances in accessing this motif we studied the effects of 3,3-diaryloxetanes on the physicochemical properties of ‘drug-like’ molecules. Here, we describe our efforts in the design and synthesis of a range of drug-like compounds for matched molecular pair analysis to investigate the viability of the 3,3-diaryloxetane motif as a replacement group in drug discovery. We conclude that the properties of the diaryloxetanes and ketones are similar, and generally superior to related alkyl linkers, and that diaryloxetanes provide a potentially useful new design element.

- Design, synthesis, and anticancer properties of novel benzophenone- conjugated coumarin analogs
-
In the current scenario, development of anticancer drugs with specific targets is of prime importance in modern chemical biology. Observing the importance of benzophenone and coumarin nucleus, it would be worthwhile to design and synthesize novel benzophenone derivatives (8a-o) bearing the coumarin nucleus. Further, they were screened for prospective anticancer activities in vitro against the Michigan Cancer Foundation-7 (MCF-7) and Ehrlich's ascites tumor (EAT) cell lines and their biomarkers, followed by in silico studies regarding phosphoinositide 3-kinase (PI3K) and caspase by molecular docking. Benzophenones have been reported as potential drugs targeting tumor angiogenesis; thus, the formation of neovessels in an in vivo model system like CAM, which is angiogenesis dependent, was observed in the presence of compounds 8a-o. The above findings would help in understanding their putative potential as therapeutic agents for cancer patients. Coumarin-integrated benzophenone conjugates (8a-o) were designed, synthesized, and screened for prospective anticancer activities in vitro against the MCF-7 and EAT cell lines. Molecular docking studies with regard to phosphoinositide 3-kinase and caspase were performed. In addition, neovessel formation was observed in an in vivo model system.

- Benzophenone-N-ethyl piperidine ether analogues-Synthesis and efficacy as anti-inflammatory agent
-
A sequence of substituted benzophenone-N-ethyl piperidine ether analogues has been synthesized and evaluated as orally active anti-inflammatory agents with reduced side effects. The anti-inflammatory and ulcerogenic activities of the compounds were compared with naproxen, indomethacin, and phenylbutazone. These analogues showed an interesting anti-inflammatory activity in carrageenan-induced foot pad edema assay. In the air-pouch test, some of the analogues reduced the total number of leukocytes of the exudate, which indicates inhibition of prostaglandin production. Side effects of the compounds were examined on gastric mucosa, in the liver and stomach. None of the compounds illustrated significant side effects compared with standard drugs like indomethacin and naproxen.
