    摘要: The present invention relates to imidazole derivatives having formula 1 ##STR1## wherein: R.sub.1 is selected from the group consisting of: mono-,di-,and tri-substituted phenyl or thienyl, the substituents are selected from the group consisting of: (i) substituted C.sub.1-6 alkyl, substituted C.sub.2-6 alkyloxy, wherein the substituents are selected from the group consisting of hydrogen or C.sub.1-6 alkoxy; (ii) C.sub.1-11 CO.sub.2 R.sub.5, trans-CH.dbd.CHCO.sub.2 R.sub.5, wherein R.sub.5 is C.sub.1-11 alkyl, or phenyl C.sub.1-11 alkyl; R.sub.2 and R.sub.3 are mono-, di, and tri-substituted phenyl wherein the substituents are independently selected from: (i) halo; (ii) C.sub.1-6 alkyl-amino, or di(C.sub.1-6 alkyl)amino, and R.sub.4 is hydrogen. These compounds are useful for restoring the sensitivity of multidrug resistant cells to cancer chemotherapeutic agents.
