| Description: | AMTB hydrochloride is a selective TRPM8 channel blocker. AMTB hydrochloride inhibits icilin-induced TRPM8 channel activation with a pIC50 of 6.23. AMTB hydrochloride can be used for the research of the overactive bladder and painful bladder syndrome. AMTB hydrochloride is a non-selective inhibitor of voltage-gated sodium channels (NaV)[1][2]. | 
| In Vivo: | In the anesthetized rat, AMTB (3 mg/kg; intravenous) hydrochloride decreases the frequency of volume-induced bladder contractions, without reducing the amplitude of contraction[1]. | 
| In Vitro: | AMTB hydrochloride blocks veratridine-induced membrane potential changes at each NaV1 isoform (pIC50s ranging 4.83-5.69 for NaV1.1- NaV1.8)[2]. AMTB hydrochloride decreases viable cell number in MDA-MB-231 and SK-BR-3 breast cancer cell lines (30 and 100 μM), and also reduces the migration of MDA-MB-231 cells (30 μM)[2]. |
