The present invention is directed to, in part, fused heteroaryl compounds and compositions useful for preventing and/or treating a disease or condition relating to aberrant function of a voltage-gated, sodium ion channel, for example, abnormal late/persistent sodium current. Methods of treating a disease or condition relating to aberrant function of a sodium ion channel including Dravet syndrome or epilepsy are also provided herein.
Synthesis of heteroaryl amines has been an important topic in organic chemistry because of their importance in small-molecule discovery. In particular, 2-aminopyrimidines represent a highlyprivilegedstructuralmotif that is prevalent in bioactive molecules, but a general strategy to introduce the pyrimidine C2–N bonds via direct functionalization is elusive. Here we describe a synthetic platform
A cephem compound of the formula:
wherein R1 stands for an optionally substituted lower alkyl group, R2 stands for H or a lower alkyl group, R3 stands for H, an optionally substituted hydrocarbon group, cyano group, a lower alkyloxy group or a lower alkylthio group, and the ring A stands for an optionally substituted non-quaternarized nitrogen-containing heterocyclic ring, provided that, when A is unsubstituted 2-pyridyl group, R3 stands for a group other than hydrogen, or their esters or salts, has excellent antibacterial activities, oral absorbability and stability, and is useful as an antibacterial agent.
