Abstract

Abstract Novel halomethyl derivatives of α-amino acids of the following general structure: ##STR1## wherein Y is F 2 CH--, F 3 C--, Cl 2 CH--; Z is β-methylthioethyl, β-thioethyl, β-benzylthioethyl; S-(5'-desoxyadenosin-5'-yl)-S-methylthioethyl, γ-guanidinopropyl, R a HN(CH 2 ) n -- wherein n is the integer 3 or 4 or ##STR2## wherein Y 2 is F 2 CH--, or F 3 C--; each of R a and R b can be the same or different and is hydrogen, alkylcarbonyl wherein the alkyl moiety has from 1 to 4 carbon atoms and is straight or branched, alkoxycarbonyl wherein the alkoxy moiety has from 1 to 4 carbon atoms and is straight or branched, or ##STR3## wherein R 2 is hydrogen, a straight or branched lower alkyl group of from 1 to 4 carbon atoms, benzyl or p-hydroxybenzyl; R 1 is hydroxy, a straight or branched alkoxy group of from 1 to 8 carbon atoms, --NR 4 R 5 wherein each of R 4 and R 5 is hydrogen or a lower alkyl group of from 1 to 4 carbon atoms, or ##STR4## wherein R 3 is hydrogen, a straight or branched lower alkyl group of from 1 to 4 carbon atoms, benzyl or p-hydroxybenzyl; and the lactams thereof when Z is R a HN(CH 2 ) n -- and each of R a and R b is hydrogen; with the provisos that when Z is γ-guanidinopropyl or β-methylthioethyl, Y is FCH 2 --, F 2 CH-- or F 3 C--; when Z is γ-guanidinopropyl, R 1 is hydroxy; and when Z is β-thioethyl, β-benzylthioethyl, S-(5'-desoxyadenosin-5'-yl)-S-methylthioethyl or ##STR5## Y and Y 2 are FCH 2 --, F 2 CH--, or F 3 C-- and are the same, each of R a and R b is hydrogen and R 1 is hydroxy; and pharmaceutically acceptable salts and individual optical isomers thereof.
