Synthesis and biological activities of fluorinated 10-hydroxycamptothecin and SN38
摘要:
It is an important strategy for fluorine substitution in drug design because of its small size and high electronegativity. Fluorinated 10-hydroxycamptothecin and SN 38 were prepared and screened for antiproliferative activities. Among them, fluorinated compound MF-6 showed higher antiproliferative activities against A549, HCT116 and MDA-MB-435 cancer cells than unfluorinated compound. The result of Topoisomerase I activity also confirmed that the C-21 carbonyl group of camptothecin structure is unnecessary to antitumor activity. (C) 2013 Elsevier B.V. All rights reserved.

β-Alanine esters of camptothecin compounds which are effective anti-tumor compounds are disclosed. These compounds inhibit the enzyme topoisomerase I and may alkylate DNA of the associated topoisomerase I-DNA cleavable complex.
