[The secretory action of various C-5-alkylsubstituted histamines and N alpha-methyl-histamines on anaesthetized cats with Heidenhain pouches (author's transl)].
In particular, the action of N alpha-methyl-histamine has to be considered since its secretory response is approximately 1.5 times greater than that of histamine and its secretion lasted for a longer period of time. After C-5-alkylsubstitution, both 5-methyl-histamine and N alpha,5-dimethyl-histamine showed secretory action comparable to that of histamine; the agonistic activity, however, decreased with increasing chain length.
