The cocaine photoaffinity label 3-iodo-4-azidococaine ([125I]IACoc) binds to the sigma-1 receptor with an affinity that is 2-3 orders of magnitude higher than the parent compound cocaine [Kahoun, J. R., and Ruoho, A. E. (1992) Proc. Natl. Acad. Sci. U.S.A. 89, 1393-1397]. In the present study, the binding properties of several cocaine derivatives to the guinea pig liver sigma-1 receptor were determined. The results from assessing the affinity of various derivatives of cocaine which were… CONTINUE READING
