Synthesis and anticancer evaluation of 3-substituted quinolin-4-ones and 2,3-dihydroquinolin-4-ones
摘要:
A series of 3-aryl-5,7-dimethoxyquinolin-4-ones 8 and 3-aryl-5,7-dimethoxy-2,3-dihydroquinolin-4-ones 13 were synthesized in good yields. Demethylation under a range of conditions afforded the corresponding 5-hydroxy and 5,7-dihydroxy derivatives. Biological evaluation against a range of cancer cells lines showed that the quinolin-4-one scaffold was more cytotoxic than the reduced 2,3-dihydroquinolin-4-one scaffold. The most active monohydroxy compound 15f demonstrated 85.9-99% reduction in cell viability against the cell lines tested. (C) 2013 Elsevier Ltd. All rights reserved.

A new cytotoxic quinolone alkaloid and a pentacyclic steroidal glycoside from the stem bark of Crataeva nurvala: Study of anti-proliferative and apoptosis inducing property
Chemical investigation of stem bark of Crataeva nurvala afforded 5,7-dimethoxy-3-phenyl-1-ethyl-1,4-dihydro-4-quinolone and a steroidal glycoside with unprecedented pentacyclic ring system named crataemine (1a) and crataenoside (2) respectively. The structures of the compounds were determined by spectroscopic analysis. A series of compounds with modification at position 1 of 1a (1a-1c) were prepared. All compounds were screened for cytotoxic activity against HeLa, PC-3 and MCF-7 cells. Only la and 2 showed potency against all three cells. Mechanism based study for activity of the compounds demonstrated that it could block the migration of more aggressive HeLa and PC-3 cells and prevent their colony formation ability as well. The compounds potentiated apoptosis in HeLa and PC-3 cells in a significant manner. (C) 2012 Elsevier Masson SAS. All rights reserved.
