The discovery of aminopyrazines as novel, potent Nav1.7 antagonists: Hit-to-lead identification and SAR
摘要:
Herein the discovery of a novel class of aminoheterocyclic Na(v)1.7 antagonists is reported. Hit compound 1 was potent but suffered from poor pharmacokinetics and selectivity. The compact structure of 1 offered a modular synthetic strategy towards a broad structure-activity relationship analysis. This analysis led to the identification of aminopyrazine 41, which had vastly improved hERG selectivity and pharmacokinetic properties. (C) 2012 Elsevier Ltd. All rights reserved.

Polyhexahydrotriazine (PHT) and polyhemiaminal (PHA) materials incorporating divalent or trivalent bridging groups tend to form highly cross-linked polymers. While highly cross-linked polymers have certain advantageous with respect to stability and various physical characteristics, they are difficult to process once formed. PHA and PHT materials incorporating a plurality of trivalent PHA/PHT groups, a plurality of divalent bridging groups, and a plurality of monovalent end groups are disclosed. According to an embodiment, the cross-link density and molecular weight can be controlled by the inclusion of the end groups. Lower cross-link density and molecular weight give PHA and PHT materials improved characteristics with respect to film and fiber formation methods. A method of coating a component or substrate with a polymer is also disclosed. Embodiments of the method can be used to form either a PHA or PHT film on a substrate, such as microelectronic component.

The presence of a large molecular dipole moment in diphenyl ethers leads unequivocally to a centrosymmetric crystalstructure.
