  Design and synthesis of N1-aryl-benzimidazoles 2-substituted as novel HIV-1 non-nucleoside reverse transcriptase inhibitors

  摘要：

  A series of novel N-1-aryl-2-arylthioacetamido-benzimidazoles were synthesized and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). Some of them proved to be effective in inhibiting HIV-1 replication at submicromolar and nanomolar concentration acting as HIV-1 non-nucleoside RT inhibitors (NNRTIs), with low cytotoxicity. The preliminary structure-activity relationship (SAR) of these new derivatives was discussed and rationalized by docking studies. (C) 2014 Elsevier Ltd. All rights reserved.

  synthesized and evaluated as anti-HIV agents. Some of them proved to be highly effective in inhibiting HIV-1 replication at nanomolar concentration as potent non-nucleoside HIV-1 RT inhibitors (NNRTIs) with low cytotoxicity. SAR studies highlighted that the nature of the substituents at N(1) and on the benzene ring of benzimidazolone moiety significantly influenced the anti-HIV activity of this class

  Chemotherapy is currently the only effective approach to treat all forms of leishmaniasis. However, its effectiveness is severely limited due to high toxicity, long treatment length, drug resistance, or inadequate mode of administration. As a consequence, there is a need to identify new molecular scaffolds and targets as potential therapeutics for the treatment of this disease. We report a small series of 1,2‐substituted‐1H‐benzo[d]imidazole derivatives (9a–d) showing affinity in the submicromolar range (Ki = 0.15–0.69 μM) toward Leishmania mexicanaCPB2.8ΔCTE, one of the more promising targets for antileishmanial drug design. The compounds confirmed activity in vitro against intracellular amastigotes of Leishmania infantum with the best result being obtained with derivative 9d (IC50 = 6.8 μM), although with some degree of cytotoxicity (CC50 = 8.0 μM on PMM and CC50 = 32.0 μM on MCR‐5). In silico molecular docking studies and ADME‐Tox properties prediction were performed to validate the hypothesis of the interaction with the intended target and to assess the drug‐likeness of these derivatives.
