Antitrypanosomal Lead Discovery: Identification of a Ligand-Efficient Inhibitor of Trypanosoma cruzi CYP51 and Parasite Growth
摘要:
Chagas disease is caused by the intracellular protozoan parasite Trypanosomal cruzi, and current drugs are lacking in terms of desired safety and efficacy profiles. Following on a recently reported high-throughput screening campaign, we have explored initial structure-activity relationships around a class of imidazole-based compounds. This profiling has uncovered compounds 4c (NEU321) and 4j (NEU704), which are potent against in vitro cultures of T. cruzi and are greater than 160-fold selective over host cells. We report in vitro drug metabolism and properties profiling of 4c and show that this chemotype inhibits the T. cruzi CYP51 enzyme, an observation confirmed by X-ray crystallographic analysis. We compare the binding orientation of 4c to that of other, previously reported inhibitors. We show that 4c displays a significantly better ligand efficiency and a shorter synthetic route over previously disclosed CYP51 inhibitors, and should therefore be considered a promising lead compound for further optimization.

Discovery and optimization of novel N-benzyl-3,6-dimethylbenzo[d]isoxazol-5-amine derivatives as potent and selective TRIM24 bromodomain inhibitors with potential anti-cancer activities
acetylated H3K23 (H3K23ac) via its bromodomain, has been closely involved in tumorigenesis or tumor progression of several cancers. Developing inhibitors of TRIM24 is significant for functional studies and drug discovery. Herein, we report the identification, optimization and evaluation of N-benzyl-3,6-dimethylbenzo[d]isoxazol-5-amines as TRIM24 bromodomaininhibitors starting from an in house library
