|Title:||Synthesis and antitumor activities of a series of novel quinoxalinhydrazides||Authors:||F., Grande

Recently, we discovered a novel class of anticancer compounds with remarkable potency in a panel of cancer cell lines. A prototype compound, SC144, showed significant in vivo efficacy in mice xenograft models of human breast cancer cells. Herein, we report on a new synthetic route to SC144 and the synthesis of several of its analogues in order to understand required features for activity. A one-step coupling of 7-fluoro-4-chloropyrrolo[1,2-a]quinoxaline with pyrazin-2-carbohydrazide improved the yield significantly. Although several of the analogues showed significant activities, modification of the heteroacyl moiety had a dramatic effect on potency.
