用途一
DA 4643 is one of histamine H2-receptor antagonistic. Two histamine H2-receptor antagonists of the phenylformamidine type, mifentidine (N-isopropyl-N'-(4-1H-imidazol-4-yl-phenyl) formamidine dihydrochloride; I) and DA 4643 (N-methyl-N'-(3-(2-guanidinothiazol-4-yl)-phenyl) formamidine dihydrochloride; II), have been investigated by experimental physico-chemical studies and theoretical conformational analysis. Both mifentidine and DA 4643 interact with the histamine H2-receptor at the same site, utilizing in the binding process the same, or closely similar, receptor structural features.常見問題列表
概述
DA 4643(鹽酸鹽)是一種H2受體拮抗劑,其化學(xué)名為2-胍基-4(3-甲基氨基亞甲基亞氨基苯基)噻唑二鹽酸鹽。它與細(xì)胞色素P-450的相互作用較弱,比西咪替丁和替奧替丁對P-450的抑制作用更小。DA 4643(鹽酸鹽)能夠抑制酶促和非酶促脂質(zhì)過氧化反應(yīng)。這種抑制作用可能不是通過抑制試劑代謝酶實現(xiàn)的,而是由于該化合物本身具有抗氧化特性。與其他H2受體拮抗劑如西咪替丁、雷尼替丁和替奧替丁相比,DA 4643(鹽酸鹽)在脂質(zhì)過氧化抑制方面表現(xiàn)出獨特的作用。這些特性使DA 4643(鹽酸鹽)成為一種潛在的具有多重作用機制的H2受體拮抗劑。
