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.
The present invention comprises novel aromatic molecules, which can be used in the treatment of pathological conditions, such as cancer, skin diseases, muscle disorders, and immune system-related disorders such as disorders of the haematopoietic system including the haematologic system in human and veterinary medicine.
