Novel 6-mercapto-12-phenethyl-quinazolino[3,4-a]quinazolinone derivatives were synthesized through a user-friendly five-step reaction starting from isatoic anhydride. All products were characterized by IR,1H-NMR,13C-NMR spectroscopy, and chemical analysis. All of them were evaluated for their in vitro cytotoxic activity against two cell lines namely MOLT-4 (human lymphoblastic leukemia) and MCF-7 (human breast adenocarcinoma).

Some cancers, like acute myeloid leukemia (AML), use reactive oxygen species to endogenously activate cell proliferation and angiogenic signaling cascades. Thus many cancers display increases in reactive oxygen like hydrogen peroxide concentrations. To translate this finding into a therapeutic strategy we designed new hydrogen peroxide-activated agents with two key molecular pharmacophores. The first pharmacophore is a peroxide-acceptor and the second is a pendant amine. The acceptor is an N-(2,5-dihydroxyphenyl)acetamide susceptible to hydrogen peroxide oxidation. We hypothesized that selectivity between AML and normal cells could be achieved by tuning the pendant amine. Synthesis and testing of fourteen compounds that differed at the pendent amine led to the identification of an agent (14) with 2 μM activity against AML cancer cells and an eleven fold-lower activity in healthy CD34+ blood stem cells. Interestingly, analysis shows that upon oxidation the pendant amine cyclizes, ejecting water, with the acceptor to give a bicyclic compound capable of reacting with nucleophiles. Preliminary mechanistic investigations show that AML cells made from addition of two oncogenes (NrasG12D and MLL-AF9) increase the ROS-status, is initially an anti-oxidant as hydrogen peroxide is consumed to activate the pro-drug, and cells respond by upregulating electrophilic defense as visualized by Western blotting of KEAP1. Thus, using this chemical approach we have obtained a simple, potent, and selective ROS-activated anti-AML agent.

Twenty scopoletin derivatives were developed by a systematic combinatorial chemical approach and their chemical structures were confirmed by MS, IR, 1H NMR spectra and elemental analysis. Primary screening against mammary (MCF-7 and MDA-MB 231) and colon (HT-29) carcinoma cells indicated that five compounds (8d, 8g, 8j, 11b and 11g) displayed high antitumor potencies with IC50 values below 20 μM whereas scopoletin showed IC50 values above 100 μM. Moreover, the most promising compound 11g was more active than 5-fluorouracil. These results clearly indicated that the modification of the scopoletin structure could greatly increase its antitumor activity in vitro.
