Abstract

Compounds characterized generally as ethynyl alanine amino diol derivatives are useful as renin inhibitors for the treatment of ophthalmic disorders. Compounds of particular interest are those of Formula I ##STR1## wherein A is selected from CO and SO.sub.2 wherein X is selected from oxygen atom and methylene; wherein each of R.sub.1 and R.sub.9 B is a group independently selected from hydrido, methyl, ethyl, n-propyl, isopropyl, benzyl, b, b, b-trifluoroethyl, t-butyloxycarbonyl and methoxymethylcarbonyl, and wherein the nitrogen atom to which R.sub.1 and R.sub.9 are attached may be combined with oxygen to form an N-oxide; wherein R.sub.2 is selected from hydrido, methyl, ethyl and isopropyl; wherein R.sub.3 is selected from benzyl, cyclohexyimethyl, phenethyl, imidazolemethyl, pyridylmethyl and 2-pyridylethyl; wherein R.sub.5 is propargyl or a propargyl-containing moiety; wherein R.sub.7 is cyclohexylmethyl; wherein each of R.sub.4 and R.sub.6 is independently selected from hydrido and methyl; wherein R.sub.8 is selected from ethyl, n-propyl, isobutyl, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclopropylmethyl, cyclohexylmethyl, cyclohexylethyl, allyl, vinyl and fluorovinyl; wherein each of R.sub.11 and R.sub.12 is independently selected from hydrido, alkyl and phenyl; wherein m is zero; and wherein n is a number selected from zero through three; or a pharmaceutically-acceptable salt thereof.
