Design and synthesis of novel 2′-hydroxy group substituted 2-pyridone derivatives as anticancer agents
摘要:
We have synthesized a series of novel 2-pyridone derivatives with 1,2,3-triazole and evaluated their antitumor activities in vitro. The bioassays showed that the majority of the resultant compounds exerted inhibitory effects on six human cancer cell lines to various extents. In particular, compound 10k showed the best anti-tumor activities (IC50 values of A549, HeLa and SW480 cancer cell lines were 0.86 +/- 0.17 mu M, 0.54 +/- 0.23 mu M and 0.21 +/- 0.13 mu M, respectively).

Anti-hepatitis B virus and anti-cancer activities of novel isoflavone analogs
摘要:
We have synthesized a series of novel isoflavone analogs and evaluated their anti-HBV and anti-cancer activities in vitro. The bioassays showed that the majority of the resultant compounds exerted inhibitory effects on HBsAg and HBeAg levels, HBV DNA replication, as well as the growth of four human cancer cell lines to various extents, which supported the rationale of the design. In particular, compound 8f showed the highest activity against HBV infection and HBV-related liver cancer. Compound 71 (IC50 = 0.47 mu M) also exerted remarkable inhibitory effect on the growth lung cancer cell line A-549. (C) 2012 Elsevier Masson SAS. All rights reserved.

different terminal olefins with various 3-iodo-benzopyrones including stericallyhindered, electron-rich, electron-neutral, and electron-deficient is developed. It proceeded faster and generally gave good to excellent yields under microwave irradiation, phosphine-free, and air condition. The reaction could render this method particularly attractive for the efficient preparation of biologically and
A series of novel 2-pyridone derivatives were synthesized and evaluated for their antihepatitis B virus (HBV) activity and cytotoxicity in vitro. Moderate to good activity against HBV DNA replication was observed in these 2-pyridone analogues. The most active compounds were 5d and 61, with good inhibitory activity against HBV DNA replication (IC50 = 0.206 and 0.12 mu M, respectively) and remarkable high selectivity (selectivity indexes of >532 and 467, respectively). A pharmacophore model of the synthesized compounds was proposed by the GASP program. The pharmacophore model consists of three hydrophobic points, four HBA points, and one HBD point. The 2-pyridone derivatives represent a novel class of HBV inhibitors, which are worth further optimization.
