Sambasivarao, K. published the artcileEffect of some antihistamines on the uterine response to estrogen in the rat, Synthetic Route of 2508-72-7, the publication is Indian Journal of Physiology and Pharmacology (1977), 21(3), 207-8, database is CAplus and MEDLINE.
Water imbibition by rat uterus induced by estradiol dipropionate (I dipropionate) [113-38-2] (10 μg/day for 5 days, i.p.) was not decreased by antihistamines, but was augmented by 1 of them, viz. antazoline-HCl [2508-72-7]. Thus, previously observed prolongation of the estrous cycle by antihistamines may not be due to blockade of uterine hyperemia or edema induced by estrogens.
Indian Journal of Physiology and Pharmacology published new progress about 2508-72-7. 2508-72-7 belongs to imidazoles-derivatives, auxiliary class Inhibitor,Immunology/Inflammation,Histamine Receptor, name is N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, and the molecular formula is C17H20ClN3, Synthetic Route of 2508-72-7.
