A compound of formula (I):
or a pharmaceutically acceptable salt thereof, wherein RA is a group of formula (a):
wherein T represents a group of formula (b):
wherein Q is
, and where
R' is a hydrogen or halogen atom or a -CF3, OR 4, NHR4, -NHCOR4, -NHCONH2, NHSO2 R4, CH2OR4 or -CH2SO2 R4 group:
R2 is a hydrogen or halogen atom or an -OR4 group;
R3 is a hydrogen or halogen atome; and R4 is hydrogen, C1-6 alkyl or benzyl;
X' is a bond or -OCH2-;
X2 is a group of formula -CR5R6-CH2-A-wherein R5 and R6 are independently hydrogen or methyl; and
A is a bond, -CH2-, or O;
T' represents a hydrogen atom or a group of formula (b) as defined above in respect of T, such that T' and T may be the same or different; RC represents a group (a) as defined above in respect of RA, such that RC and RA may be the same or different; provided that when RA and RC each represent a group of formula:
wherein R is oH or -O-benzyl; then when A is a bond, -CH2- or -0, R' is not -CH2OH or NHSO2-C1-4 alkyl; processes for the preparation of such compounds and their use in medicine and agriculture.
