Discovery of novel PTP1B inhibitors via pharmacophore-oriented scaffold hopping from Ertiprotafib
摘要:
An integrated molecular design strategy combining pharmacophore recognition and scaffold hopping was exploited to discover novel PTP1B inhibitors based on the known PTP1B inhibitor Ertiprotafib. A composite pharmacophore model was proposed from the interaction mode of Ertiprotafib, and 21 diverse molecules from five distinct structural classes were designed and synthesized accordingly. New compounds with considerable inhibition against PTP1B were identified from each series, and the most active compound 3a showed IC50 value of 1.3 mu mol L-1 against human recombinant PTP1B. Docking study indicated that the new inhibitors assumed binding modes similar to that of Ertiprotafib. (C) 2013 Elsevier Ltd. All rights reserved.
Tricyclononene carboxamide derivatives as novel anti-HIV-1 agents
摘要:
By modifying the chemical structure of anti-orthopoxvirus compound ST-246, we designed and synthesized a series of tricyclononene carboxamide derivatives and tested their anti-HIV-1 activity and cytotoxicity. We found that benzoimidazol-containing compound 7g was highly effective in inhibiting HIV-1 R5 infection with an IC50 value of 0.41 mu M and a selectivity index of 292, but it exhibited no significant inhibitory activity on HIV-1 reverse transcriptase, integrase and protease. CoMFA was used to analyze structure-activity relationships with good predictive power (r(2) = 0.921; q(2) = 0.582). Moreover, the CoMFA model showed that the length of the molecule, the amide, and the amine moieties all played crucial roles in anti-HIV activity. These results suggest that 7g may serve as a lead for the development of novel anti-HIV-1 therapies. (C) 2010 Elsevier Masson SAS. All rights reserved.
