Discovery of a 1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione series of inhibitors of HIV-1 capsid assembly
摘要:
The discovery of a 1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione series of inhibitors of HIV-1 capsid assembly is described. Synthesis of analogs of the 1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione hit established structure-activity relationships. Replacement of the enamine functionality of the hit series with either an imidazole or a pyrazole ring led to compounds that inhibited both capsid assembly and reverse transcriptase. Optimization of the bicyclic benzodiazepine scaffold to include a 3-phenyl substituent led to lead compound 48, a pure capsid assembly inhibitor with improved antiviral activity.

Discovery of 2-iminobenzimidazoles as potent hepatitis C virus inhibitors with a novel mechanism of action
摘要:
In this report we describe 2-iminobenzimidazole (IBI) analogs, identified during the course of a phenotypic high-throughput screening campaign, as novel hepatitis C virus (HCV) inhibitors. A series of IBI derivatives was synthesized and evaluated for their inhibitory activity against infectious HCV. Among the IBIs derivatives studied in this work, we identified promising compounds with high antiviral efficacy, high selectivity index and good microsomal stability. Noteworthy, the IBI series exhibited inhibitory activity on early and late steps of the viral cycle, but not in the HCV replicon system demonstrating a mechanism of action distinct from clinical-stage and approved anti-HCV drugs. Overall, our results suggest that IBIs are predestinated for further exploration as lead compounds for novel HCV interventions. (C) 2014 Elsevier Masson SAS. All rights reserved.

benzoXazole-2(3H)-thiones) as inhibitors of the chymotrypsin-like (β5i) subunit of the immunoproteasome. A subsequent structure-activity relationship study provided us with an insight regarding growing vectors. Binding to the β5i subunit was shown and selectivity against the β5subunit of the constitutive proteasome was determined. Thorough characterization of these compounds suggested that they inhibit the immunoproteasome

Emitters go spiro: Using spiroconjugated tetraamines as a novel type of donor and a range of different acceptors in three different modes of connection, 12 donor-acceptor compounds are synthesized. Their twisted structures lead to a spatial separation of the HOMOs and LUMOs. Photophysical measurements show tunable emission colors for these donor-acceptor compounds, and photoluminescence quantum yields
