Design and synthesis of chromogenic thiopeptolide substrates as MetAPs active site probes

Twenty one chromogenic thiopeptolide substrates were designed and synthesized as the active site probes and analyzed with each S1 site of mutant residues and enzymes of wild-type MetAP1s. The preliminary enzymatic experiments indicate that cysteine 70 or 202, at either Escherichia coli or human MetAP1, played a crucial role in the methionine hydrolysis.

THIOLACTONE ANTIBIOTICS

This invention provides a compound having the structure (I) wherein R1 is H, (II) or (III), wherein n and q are independently an integer from 0 to 8; A is absent or present and when present is (IV), (V), (VI), (VII), (VIII), or (IX), wherein m is an integer from 0 to 8; R3 is an amino, alkyl, aryl, heteroaryl, diol, piperazine, morpholine, piperidine, triazole, azide or biphenyl, each with or without substitution, branched or unbranched, or (X); and R4 is alkyl, aryl, or heteroaryl, each with or without substitution, branched or unbranched, R2 is H, CH3, or alkyl, aryl, heteroaryl, pyrrole, diazole, or triazole, each with or without substitution, branched or unbranched, or (XI), wherein n and q are independently an integer from 0 to 8; A is absent or present and when present is (IV), (V), (VI), (VII), or (VIII); and R6 is azide, methoxy, trifluoromethyl, biphenyl, substituted phenyl, substituted triazole, or alkyl, aryl or heteroaryl, with or without substitution, branched or unbranched, when R1 is H then R2 is other than H or CH3, and when R2 is H or CH3 then R1 is other than H, or a pharmaceutically acceptable salt thereof.
