    摘要: Compounds of the Formula I: ##STR1## and pharmaceutically acceptable salts thereof are inhibitors of leukotriene biosynthesis. These compounds inhibit the mammalian 5-lipoxygenase enzyme, thus preventing the metabolism of arachidonic acid to the leukotrienes. These compounds are thus useful in the treatment of asthma, allergic disorders, inflammation, skin diseases and certain cardiovascular disorders.

    摘要: Disclosed herein are peptide derivatives which inhibit the activities of human immunodeficiency virus (HIV) protease and renin. The peptide derivatives can be represented by general formula R.sup.1 --R.sup.2 --Y--R.sup.3 --R.sup.4 wherein R.sup.1 is a derived amino acid based on an O.sup.4 -(carboxymethyl)-tyrosyl residue, R.sup.2 and are amino acid or analogous amino acid residues (R.sup.3 may optionally be absent), Y is a non-peptide linking unit, e.g. statyl, and R.sup.4 is [--NR.sup.17 CHR.sup.18 --C(O)].sub.p --Z wherein R.sup.17 is hydrogen or lower alkyl, R.sup.18 is an amino acid or analogous amino acid side chain, p is zero or one and Z is a terminal group (e.g. hydroxy or amino), or R.sup.4 is --NR.sup.17 CR.sup.18 (R.sup.21)CH.sub.2 OH wherein R.sup.17 and R.sup.18 are as noted hereinabove and R.sup.21 is hydrogen, lower alkyl or hydroxy(lower)alkyl. The derivatives are useful as agents for combatting HIV infections and for treating renin-associated hypertension and congestive heart failure.
