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