P/Q-type calcium channel Inhibitor

ω-Agatoxin IVA TFA is a potent, selective P/Q type Ca²⁺ (Cav2.1) channel blocker with IC₅₀ values of 2 nM and 90 nM. ω-Agatoxin IVA TFA inhibits glutamate exocytosis and calcium influx elicited by high potassium. ω-Agatoxin IVA TFA inhibits Capsaicin (HY-10448)-induced CGRP release and vasodilation. ω-Agatoxin IVA TFA can be used for the research of neurological and cardiovascular disease.

ω-Agatoxin TK, a peptidyl toxin of the venom of Agelenopsis aperta, is a potent and selective P/Q type Ca²⁺ channel blocker. ω-Agatoxin TK inhibits the high K⁺ depolarisation-induced rise in internal Ca²⁺ in cerebral isolated nerve endings with an IC₅₀ of of 60 nM. ω-Agatoxin TK has no effect on L-type, N-type, or T-type calcium channels.

LY393615 (NCC1048) is a novel neuronal Ca²⁺ (calcium channel) and Na ⁺ channel (sodium channel) blocker with IC₅₀s of 1.9 μΜ and 5.2 μΜ for α1A and α1B calcium channel subunits. LY393615 has good brain penetration and neuroprotective effects in models of in cerebral ischemia that can be used for neurological disease research.
