Batimastat (INN/USAN, codenamed BB-94) is an anticancer drug that belongs to the family of drugs called angiogenesis inhibitors. It acts as a matrix metalloproteinase inhibitor (MMPI) by mimicking natural MMPI peptides.
Batimastat was the first MMPI that went into clinical trials. First results of a Phase I trial appeared in 1994. The drug reached Phase III but was never marketed; mainly because it couldn’t be administered orally (as opposed to the newer and chemically similar MMPI marimastat), and injection into the peritoneum caused peritonitis.[1]

The treatment of D-leucine (I) with NaNO2, H2SO4 and NaBr gives 2(R)-bromo-5-methylpentanoic acid (II), which is esterified with isobutene and H2SO4 to the corresponding tert-butyl ester (III). The condensation of (III) with dibenzyl malonate (IV) by means of potassium tert-butoxide in DMF yields the malonyl derivative (V), which is treated with trifluoroacetic acid to hydrolyze the tert-butyl ester, and without isolation is condensed with L-phenylalanine methyl amide (VI) by means of hydroxybenzotriazole (HOBT) and dicyclohexylcarbodiimide (DCC), affording 4-benzyloxy-3-(benzyloxycarbonyl)-2(R)-isobutylsuccinyl-L-phenylalanine methylamide (VII). The elimination of the benzyl groups of (VII) by hydrogenolysis over Pd/C in ethanol gives the dicarboxylic acid (VIII), which by partial decarboxylation and reaction with aqueous formaldehyde and piperidine yields 4-hydroxy-2(R)-isobutyl-3-methylenesuccinyl-L-phenylalanine methylamide (IX). The addition of thiophene-2-thiol (X) to the double bond of (IX) affords 4-hydroxy-2(R)-isobutyl-3(S)-(2-thienylsulfanylmethyl)succinyl-L-phenylalanine methylamide (XI), which is finally treated with hydroxylamine and hydroxybenzotriazole in dichloromethane/DMF.
