组胺-α，α，β，β-d4二盐酸盐是组胺的氘代类似物，存在于大多数哺乳动物组织中，主要储存在嗜碱性粒细胞和肥大细胞中。该化合物通过至少3种特异性受体表现出多种生物学作用，并诱导血管舒张和支气管收缩，刺激胃酸分泌。 Histamine-α,α,β,β-d4 Dihydrochloride is a deuterated analog of histamine, which is present in most mammalian tissues primarily stored in basophils and mast cells. This compound exhibits multiple biological effects through at least 3 specific receptors and induces vasodilation and bronchoconstriction snd stimulates gastric acid secretion.
