Amifampridine-d₃  (Synonyms: 3,4-Diaminopyridine-d₃)

Amifampridine-d₃ (3,4-Diaminopyridine-d₃) is deuterium labeled Amifampridine. Amifampridine (3,4-Diaminopyridine) is an orally active, potent and cell permeable voltage-gated potassium (K_v) channel blocker (PCB). Amifampridine is efficacy in the reversal of BoNT/A (HY-P79153) intoxication. Amifampridine increases transmitter release from neuromuscular junctions (NMJs). Amifampridine can be used for Lambert-Eaton myasthenic syndrome (LEMS) research^[1][2][3].

氢、碳和其他元素的稳定重同位素已被掺入药物分子中，主要用作药物开发过程中定量的示踪剂。氘化因其可能影响药物的药代动力学和代谢特征而受到关注。
