Chlorpromazine (3 x 10(-4)M) prevents the stimulation of adenyl cyclase activity in thyroid membranes produced by thyrotropin and prostaglandin, ACTH stimulation of adenyl cyclase in adrenal tissue, and glucagon- and epinephrine-stimulation of adenyl cyclase activity in liver. Baseline activity is unaffected. Parathyroid hormone stimulation of kidney preparations was not inhibited under these c...

The surface activity of triflupromazine, chlorpromazine, promazine, promethazine, and chlorpromazine sulfoxide has been determined at the air-solution interface by the drop-volume method to measure surface tension. Differences in the abilities of the various phenothiazines employed to affect surface pressure development seem correlated with their relative nonpolarities. Anionic buffer ingredien...
