  New inhibitors of tyrosyl-DNA phosphodiesterase I (Tdp 1) combining 7-hydroxycoumarin and monoterpenoid moieties

  摘要：

  A number of derivatives of 7-hydroxycoumarins containing aromatic or monoterpene substituents at hydroxy-group were synthesized based on a hit compound from a virtual screen. The ability of these compounds to inhibit tyrosyl-DNA phosphodiesterase I (Tdp 1), important target for anti-cancer therapy, was studied for the first time. It was found that the 7-hydroxycoumarin derivatives with monoterpene pinene moiety are effective inhibitors of Tdp 1 with the most active derivative (+)-25c with IC50 value of 0.675 mu M. This compound has low cytotoxicity (CC50 >100 mu M) when tested against human cancer cells which is crucial for presupposed application in combination with clinically established anticancer drugs. The ability of the new compounds to enhance the cytotoxicity of camptothecin, an established topoisomerase 1 poison, was demonstrated. (C) 2016 Elsevier Ltd. All rights reserved.

  A large series of coumarin derivatives (71 compounds) were tested for their monoamine oxidase A and B (MAO-A and MAO-B) inhibitory activity. Most of the compounds acted preferentially on MAO-B with IC50 values in the micromolar to low-nanomolar range; high inhibitory activities toward MAO-A were also measured for sulfonic acid esters. The most active compound was 7-[(3,4-difluorobenzyl)oxy]-3,4-dimethylcoumarin, with an IC50 value toward MAO-B of 1.14 nM. A QSAR study of 7-X-benzyloxy meta-substituted 3,4-dimethylcoumarin derivatives acting on MAO-B yielded good statistical results (q(2) = 0.72, r(2) = 0.86), revealing the importance of lipophilic interactions in modulating the inhibition and excluding any dependence on electronic properties. CoMFA was performed on two data sets of MAO-A and MAO-B inhibitors. The GOLPE procedure, with variable selection criteria, was applied to improve the predictivity of the models and to facilitate the graphical interpretation of results.
