In the treatment of oestrogen-dependent tumours, it is desirable to improve the therapy obtainable from the compound aminoglutethimide. It has now been found that 3-ethyl-3-(4-pyridyl)glutarimide derivatives of formula
wherein:
(a) R' represents an ethyl group and R2 repsesents a methyl group, an alkyl or cycloalkyl group having 3 to 10 carbon atoms, or a fluoroalkyl group having 2 to 10 carbon atoms;
(b) R represents an alkyl group having 3 to 10 carbon atoms or a fluoroalkyl group having 2 to 5 carbon atoms and R2 represents a hydrogen atom; or,
(c) R1 represents an alkyl group having 3 to 8 carbon atoms or a fluoroalkyl group having 2 to 5 carbon atoms and R2 represents an alkyl or fluoroalkyl group having 2 to 8 carbon atoms, provided that the total number of carbon atoms in R1 and R2 is not more than 10; and therapeutically acceptable acid addition salts of the above compounds.
