(Biphenyl-4-yl)methylammonium Chlorides: Potent Anticonvulsants That Modulate Na+ Currents
摘要:
We have reported that compounds containing a biaryl linked unit (Ar-X-Ar') modulated Na+ currents by promoting slow inactivation and fast inactivation processes and by inducing frequency (use)-dependent inhibition of Na+ currents. These electrophysiological properties have been drugs. In this study, we demonstrate that the readily accessible associated with the mode of action of several antiepileptic (biphenyl-4-yl)methylammonium chlorides (compound class B) exhibited a broad range of anticonvulsant activities in animal models, and in the maximal electroshock seizure test the activity of (3'-trifluoromethoxybiphenyl-4-yl)methylammonium chloride (8) exceeded that of phenobarbital and phenytoin upon oral administration to rats. Electrophysiological studies of 8 using mouse catecholamine A-differentiated cells and rat embryonic cortical neurons confirmed that 8 promoted slow and fast inactivation in both cell types but did not affect the frequency (use)-dependent block of Na+ currents.

peptidomimetic inhibitors of the coagulation factorXa (fXa) could help set more effective therapeutic options (to prevent atrial fibrillation). In this respect, we explored the conformational impact on the enzyme inhibition potency of the malonamide bridge, compared to the glycinamide one, as a linker connecting the P1 benzamidine anchoring moiety to the P4 aryl group of novelselective fXa inhibitors. We carried
seriously undesirable effects. Trace amine-associated receptor 1 (TAAR1) has emerged as an ideal target for the design of antischizophrenia drugs, with the ability to mediate multiple psychological functions by sensing endogenous amine-containing metabolites without the side effects of catalepsy. In this work, a series of novel TAAR1 agonists were designed based on the structural analysis of the TAAR1 activation
现有的抗精神病药物未能治疗精神分裂症的认知障碍,并引发了许多严重的不良反应。痕量胺相关受体 1 (TAAR1) 已成为抗精神分裂症药物设计的理想靶标,能够通过感知内源性含胺代谢物来介导多种心理功能,而不会产生僵住症的副作用。在这项工作中,基于TAAR1激活口袋的结构分析,设计了一系列新型TAAR1激动剂。其中, 6e表现出有效的TAAR1-G s /G q双通路激活特性,与仅激活TAAR1-G s通路的临床候选药物SEP-363856不同。在啮齿动物模型中, 6e显着减轻 MK-801 诱导的精神分裂症样认知表型,但不会诱发僵直症。此外, 6e·HCl表现出良好的药代动力学( T 1/2 = 2.31 h, F = 39%)和安全特性。这些都表明6e·HCl可作为治疗精神分裂症的新候选药物。
