Proapoptotic activity of heterocyclic compounds containing succinimide moiety in the promyelocytic leukemia cell line HL-60.

In the present paper, we describe proapoptotic activity of several heterocyclic compounds 9, 12, 18, 19 and 20 possessing succinimide (as well as succinimide related) moieties. The compounds properties were examined with the aid of flow cytometry on the promyelocytic leukemia cell line HL-60. The highest proapoptotic activity exhibited compound 12 (4-{4-[4-(2-methoxyphenyl)piperazin-1-yl]butyl}-1,7-diethyl-8,9diphenyl-4-azatricyklo[5.2.1.0]-dec-8-ene-3,5,10-trione). The synthesis of compounds 1-17 is also described. The structures of obtained compounds were characterized by H NMR, C NMR, ESI MS and/or elemental
