Structure-based discovery of a family of synthetic cyclophilin inhibitors showing a cyclosporin-A phenotype in Caenorhabditis elegans
چکیده انگلیسی

Cyclophilins, which are found in all cellular compartments and with diverse biological roles, are now drug targets for a number of diseases including HIV infection, malaria and ischaemia. We used the database-mining program LIDAEUS and in silico screening to discover the dimedone family of inhibitors which show a conserved ‘ball and socket’ binding mode with a dimethyl group in the hydrophobic binding pocket of human cyclophilin A (CypA) mimicking a key interaction of the natural inhibitor cyclosporin A (CsA). The most potent derivative binds CypA with a Kd of 11.2 ± 9.2 μM and an IC50 for activity against Caenorhabditis elegans (C. elegans) of 190 μM compared to 28 μM for CsA. These dimedone analogues provide a new scaffold for the synthesis of families of peptidomimetic molecules with potential activity against HIV, malaria, and helminth parasite infections.
