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.
体外研究
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.
体内研究
ML204 hydrochloride (1 mg/kg; s.c.; twice a day; for 5 days) causes mortality associated with exacerbated hypothermia and decreases peritoneal leukocyte numbers and cytokines in LPS-injected mice.
Animal Model:
Nonfasted male C57BL/6 (2-3 months)
Dosage:
1 mg/kg
Administration:
Subcutaneous injection, twice a day, for 5 days (prior to LPS injection)
Result:
Induces mortality associated with increased hypothermia in mice with LPS-induced systemic inflammatory response.
