Dual action Smac mimetics-zinc chelators as pro-apoptotic antitumoral agents / L. Manzoni, D. Gornati, M. Manzotti, S. Cairati, A. Bossi, D. Arosio, D. Lecis, P. Seneci. - In: BIOORGANIC & MEDICINAL CHEMISTRY LETTERS. - ISSN 0960-894X. - 26:19(2016), pp. 4613-4619.
Abstract:
Dual action compounds (DACs) based on 4-substituted aza-bicyclo[5.3.0]decane Smac mimetic scaffolds (ABDs) linked to a Zn(2+)-chelating moiety (DPA, o-hydroxy, m-allyl, N-acyl (E)-phenylhydrazone) through their 10 position are reported and characterized. Their synthesis, their target affinity (XIAP BIR3, Zn(2+)) in cell-free assays, their pro-apoptotic effects and cytotoxicity in tumor cells with varying sensitivity to Smac mimetics are described. The results are interpreted to evaluate the influence of Zn(2+) chelators on cell-free potency and on cellular permeability of DACs, and to propose novel avenues towards more potent antitumoral DACs based on Smac mimetics and Zn(2+) chelation.
