ML204 hydrochloride 是一个有效的、选择性的 TRPC4/TRPC5 通道的抑制剂，较 TRPC6 的选择性高出 20 倍，不影响其他的 TRP 通道和电压门控的钠、钾或 Ca²⁺ 通道。

ML204 hydrochloride is a novel, potent, selective TRPC4/TRPC5 channel inhibitor, with at least 19-fold selectivity against TRPC6 and no appreciable effect on all other TRP channels, nor on voltage-gated sodium, potassium, or Ca channels.

Solid

TRPC4 TRPC5

ML204 hydrochloride inhibits TRPC4β-mediated intracellular Ca rise with an IC50 value of 0.96 μM (HEK293 cells) and exhibits 19-fold selectivity against muscarinic receptor-coupled TRPC6 channel activation.
ML204 hydrochloride blocks TRPC4β activity induced through either Gi/o stimulation by μ-opioid, 5HT1A serotonin, and M2 muscarinic receptors or Gq/11 stimulation by the endogenous M3-like muscarinic receptors.
ML204 hydrochloride blocks LPS-induced TRPC5 channel activity.
