Disclosed herein are peptide derivatives which inhibit the activity of human immunodeficiency virus (HIV) protease. The peptide derivatives can be represented by general formula R¹-R²-Y-R³-R⁴ wherein R¹ is an optionally substituted 3-(1,2,3,4-tetrahydroisoquinolyl)carbonyl residue, R² and R³ are amino acid or analogous amino acid residues (R³ may optionally be absent), Y is a non-peptide linking unit, e.g. statyl, and R⁴ is [-NR¹⁷CH(R¹⁸)C(O)]p-Z wherein R¹⁷ is hydrogen or lower alkyl, R¹⁸ is an amino acid or analogous amino acid side chain, p is zero or 1 and Z is a terminal group (e.g. hydroxy or amino), or R⁴ is -NR¹⁷CR¹⁸(R²¹)CH₂OH wherein R¹⁷ and R¹⁸ are as noted hereinabove and R²¹ is hydrogen, lower alkyl or hydroxy(lower)alkyl. The derivatives also inhibit renin activity. Accordingly, the derivatives can be used for combating HIV infections or for treating hypertension or congestive heart failure.
