There are described new compounds of formula (1)
wherein
R¹ represents an acyl group;
X¹ represents phenylalanine or p-methoxyphenylalanine bonded N-terminally to R¹ and C-terminally to X²;
X² represents histidine or N-methylhistidine bonded N-terminally to X¹ and C-terminally to the group -NH-;
R² represents a C₄₋₆ cycloalkyl group;
R³ represents a group CHR⁶R⁷ (where R⁶ is a hydrogen atom or a hydroxyl group and R⁷ is a pyridinyl ring);
X³ represents a C₂₋₆ alkylene chain optionally substituted by one or more C₁₋₄ alkyl groups;
R⁴ and R⁵, which may be the same or different, each independently represent a hydrogen atom or a C₁₋₄ alkyl group, or NR⁴R⁵ may form a 5- or 6- membered polymethylenimine ring;
and salts and solvates thereof.
The new compounds have been found to exhibit activity as renin inhibitors, combining good duration of action with significant oral potency.
Compositions containing the compounds of formula (1) and processes for preparing the compounds are also described.
