Abstract

Forty four di- or trisubstituted novel isatin derivatives were designed and synthesized in 5-6 steps in 25-45% overall yields. Their structures were confirmed by (1)H NMR and (13)C NMR as well as LC-MS. The Anticancer activity of these new isatin derivatives against three human tumor cell lines, K562, HepG2 and HT-29, were evaluated by MTT assay in vitro. SAR studies suggested that the combination of 1-benzyl and 5-[trans-2-(methoxycarbonyl)ethen-1-yl] substitution greatly enhance their cytotoxic activity, whereas an intact carbonyl functionality on C-3 as present in the parent ring is required to such a potency. This study leads to the identification of two highly active molecules, compounds 2h (IC50=3 nM) and 2k (IC50=6 nM), against human leukemia K562 cells.
