Neuronal sodium channels blockers interfere with ion flux and have been used for managing neuropathic pain, epilepsy, and cerebral ischemic disorders. In the current study, four groups of 2, 4-diamino-1, 3, 5-triazine derivatives were synthesized and investigated for their neuronal sodium channels binding activity. 5-Aryl-1, 3, 5-triazaspiro [5.5] undeca-1, 3- diene-2, 4-diamines (4a–4j) were found to have the best neuronal sodium binding activity ...
