  Design of a hydrogen peroxide-activatable agent that specifically targets cancer cells

  摘要：

  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 mu M 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. (C) 2014 Elsevier Ltd. All rights reserved.

  The merits of N-unsubstituted indoles and cyclopent[b]indoles as DNA-directed reductive alkylating agents are described. These systems represent a significant departure from N-substituted and pyrrolo[1,2-a] fused systems such as the mitomycins and mitosenes. The cyclopent[b]indole—based aziridinylquinone, when bearing an acetate leaving group, was found to be cytotoxic and displayed significant in vivo activity against syngeneic tumor implants. This particular analogue was unexpectedly superior to the others studied, both in terms of high specificity for the activating enzyme DT-diaphorase and in high % DNA alkylation. Alkylation by a quinone methide intermediate as well as by the aziridinyl group were examined for crosslinking. The possible metabolites of the most active indole species were prepared and found to retain cytotoxicity, strongly suggesting that in vivo activity could also be sustained. The indole systems in the present invention display selectivity for melanoma and for non small cell lung, colon, renal, and prostate cancers when administered in an effective amount. The cancer specificity observed is believed to pertain to differential substrate specificity for DT-diaphorase.
