This invention provides 1,4-dihydropyridine derivatives based on the general formula
such as dimethyl 1,4-dihydro-4-(3,4-dimethoxyphenyl)-2,6-dimethyl-1-(3-phenylpropyl)-3,5-pyridinedicarboxylate.
These derivatives are active against drug-resistant tumour cells by acting to inhibit the excretion of chemotherapeutic agents from the tumour cells.
