 Use of Guanidinoethyl sulfonate


Guanidinoethyl sulfonate (Taurocyamine), a transport antagonist of taurine, induces much urinary taurine excretion with a resulting decrease in the tissue taurine content and readily produces taurine-deficient fetal rats in pregnant rats[1]. Guanidinoethyl sulfonate, a structural analogue of taurine, acts as a competitive inhibitor of taurine transport[2].
