Chemiluminescence in visible region was detected, during peroxidase-catalyzed oxidation of chlorpromazine at pH7.5 (but not at pH4.25) or of propericiazine, both at pH7.5 and at pH4.25. Red colored intermediates, cation radicals, were produced and decayed in all enzymatic systems used.

The effects of phenothiazines (chlorpromazine, chlorpromazine sulfoxide, and trifluoperazine) and antimitotic drugs (colchicine and vinblastine) on the erythrocyte membrane have been investigated. Chlorpromazine and trifluoperazine induced a dose-dependent increase in the freedom of motion of stearic acid spin-labels bound to

We investigated the effects of various phenothiazines on the Na+-H+ exchanger in brush-border membrane vesicles isolated from the proximal small intestine of the rabbit. The Na+-H+ exchanger activity was assayed by measuring the dimethylamiloride-sensitive Na+ uptake into these vesicles in
