Synthesis of non-immunosuppressive cyclophilin-Binding cyclosporin A derivatives as potential anti-HIV-1 drugs
摘要:
Original cyclosporin A (CsA) derivatives bearing various alkylthio side chains at the sarcosine residue 3 (R configuration) and for the most potent and selective compounds a 4'-hydroxyl group at the Me-Leucine residue 4 were prepared in one or two steps from commercially available CsA. The [2-(dimethyl or diethylamino)-ethylthio-Sar](3)-[(4'-OH)MeLeu](4)-CsA derivatives 3k and 3l displayed potent in vitro anti-HIV-1 (IC50 similar to 46 nM) and low immunosuppressive activities (IC50 > 1500 nM).
