Novel 3,5-disubstituted 1,2,4-thiadiazole compounds are provided, which are effective in treating peptic ulcers by the inhibition of H.sup.+ /K.sup.+ -ATPase. The compounds of the present invention are 3,5-disubstituted 1,2,4-thiadiazole corresponding to the general formula (I): ##STR1## where R.sup.1 is a group with cell penetration properties for the inhibition of the enzyme in-vitro and in-vivo, and Y is a substituent that tunes the reactivity of the inhibitor towards the cysteine residue of H.sup.+ /K.sup.+ -ATPase. The Y group may also serve in recognition.
提供了一种新型的3,5-二取代的1,2,4-噻二唑化合物,通过抑制H.sup.+ /K.sup.+ -ATPase来有效治疗消化性溃疡。本发明的化合物是与通用式(I)相对应的3,5-二取代的1,2,4-噻二唑:其中R.sup.1是具有细胞穿透性质的基团,用于体外和体内抑制酶活性,Y是调节抑制剂对H.sup.+ /K.sup.+ -ATPase半胱氨酸残基的反应性的取代基。Y基团也可以用于识别。
