Facile and Efficient Oxidation of Quinazolines into Quinazolin-4(3H)-ones by Peracetic Acid
摘要:
A new approach to synthesize quinazoline-4(3H)-ones was achieved by oxidation of quinazolines using peracetic acid, which possesses some advantages of economic reagents, simplified operation, high efficiency, and environmental friendliness. Application of this method allowed us to synthesize a series of quinazolin-4(3H)-ones with different substituents at 6 and 7 positions in good to excellent yields, including the key intermediates of tyrosine kinase inhibitors such as PD153035, Erlotinib, and Gefitinib.

A series of novel 6H-[1]benzothiopyrano[4,3-b]quinoline derivatives were prepared and evaluated for their anti-hepatitis B virus (HBV) activity and cytotoxicity in human hepatoblastoma-derived liver Hep-G2 cells. Compounds 10g, 10h, 10j, 10l and 10o were found to be potent anti-HBV compounds with IC50 values less than 50 μM. The most promising compound was 10l, with an IC50 value of 14.7 μM and a SI

A series of novel quinoline-3-carboxamide derivatives 10-17 and 23-27 were designed and synthesized as cholesteryl ester transfer protein (CETP) inhibitors. All of them exhibited activity against CETP. Particularly, compounds 24 and 26 displayed the best activity against CETP with the same inhibitory rate of 80.1%.

A series of non-nucleoside ethyl 6-hydroxyquinoline-3-carboxylate derivatives were prepared and evaluated in HepG2.2.15 cells. Most compounds inhibited the expression of viral antigens HBsAg or HBeAg at low concentration. Six compounds, 9f(3), 12b(6), 12f(6), 13b(2), 13b(6), and 13f(6), displayed excellent intracellular inhibitory activity and selectivity towards the replication of HBV DNA. Of these
