There are described compounds of formula I,
in which
one of R₃₀ and R₄₀ represents a group Ra,
and the other of R₃₀ and R₄₀ represents hydrogen or halogen,
R₅₀ and R₆₀, which may be the same or different, each independently represent hydrogen or alkyl C 1 to C6; in addition R₆₀ may represent a group Rb,
wherein X represents a C2 to C8 alkylene chain optionally interrupted by a double bond or by S(0)n, wherein n is 0, 1 or 2, Z represents a C 1 to C3 alkylene chain, each of X and Z being optionally substituted by OH or one or more alkyl C 1 to C6,
R₇₀ represents hydrogen, alkyl C 1 to C6 or (CH₂)qR₁₁,
R₁₀ and R₁₁ independently represent phenyl substituted by one or more substituents R₂₃, which may be the same or different; or R₁₀ represents a saturated carbocyclic group,
R₁₅ represents hydrogen, alkyl C 1 to C6, or together with R₂₃ forms a (CH₂)p chain, wherein p represents 0, 1 or 2,
R₂₀, R₂₁, R₂₂ and R₂₃ independently represent hydrogen, alkyl C 1 to C6, NHR₂₅, SH, NO₂, halogen, CF₃, SO₂R₂₆, CH₂₀H or OH, wherein R₂₅ represents hydrogen, alkyl C 1 to C6 or alkanoyl C 1 to C6 and R₂₆ represents alkyl C 1 to C6 or NH₂
l represents 2, 3 or 4,
q represents an integer from 1 to 6 inclusive,
provided that when R₄₀, R₅₀ and R₇₀ each represent hydrogen and R₆₀ represents Rb,
then Ra represents 2(3-hydroxyphenyl)ethyl, R₁₅ represents hydrogen and either
a) X represents (CH₂)p, in which p is 3, 5, 7 or 8 or
b) at least one of X and Z is substituted by either OH or one or more alkyl C 1 to C6,
and pharmaceutically acceptable salts and solvates thereof.
There are also described processes for the preparation of the compounds of formula I and pharmaceutical compositions containing them. The compounds of the invention may be used in the treatment or prophylaxis of renal failure or cardiovascular disorders.
