Design and Synthesis of Novel Pyrazole-based Lp-PLA2 Inhibitors
摘要:
AbstractA series of novel pyrazole‐based lipoprotein‐associated phospholipase A2 (Lp‐PLA2) inhibitors have been designed and synthetized by a variety of acetophenones via a 10‐step convergent approach. The synthetic approach is carefully optimized, and an unsuccessful alternative route is also discussed. The in vitro biological activity reveals that all the synthesized compounds are potent Lp‐PLA2 inhibitors with compound 13b being the most potent one (Lp‐PLA2, IC50=1.5 nmol/L).
In our endeavour towards the development of effective anticancer therapeutics, a novel series of isoxazole-piperazine hybrids were synthesized and evaluated for their cytotoxic activities against human liver (Huh7 and Mahlavu) and breast (MCF-7) cancer cell lines. Within series, compounds 5l-o showed the most potent cytotoxicity on all cell lines with IC50 values in the range of 0.3-3.7 μM. To explore

An efficientsynthesis of novel ethyl-1,3,4-triphenyl-1H-pyrazolo[3,4-b]pyridine-6-carboxylate products has been achieved via condensation of pyrazole-5-amine derivatives and activated carbonyl groups, in refluxing acetic acid. This process has been found to be useful in the preparation of new N-fused heterocycle products in good to excellent yields.
