CA 2247899

Thiols are trapped, and converted to disulfide compounds, by a process of reacting them with compounds containing a 1,2,4-thiadiazole ring structure carrying a substituent at position 3 of the thiadiazole ring, and being unsubstituted at position N-2. The process is useful pharmacologically, in inhibiting certain thiol-containing enzymes such as H+/K+-ATPase (the proton pump), and industrially, in selective removal of thiol compounds from gas or liquid mixtures.

On piège des thiols et on les convertit en composés disulfure en les faisant réagir avec des composés contenant une structure cyclique de 1,2,4-thiadiazole portant un substituant en position 3 du cycle thiadiazole, et non substitués en position N-2. Ce procédé présente un intérêt pharmacologique du fait qu'il permet d'inhiber certains enzymes contenant des thiols tels que la H?+¿/K?+¿-adénosine triphosphatase (la pompe à protons) et il présente également un intérêt industriel s'agissant de l'extraction sélective de composés de thiols à partir de mélanges de gaz ou de liquides.
