Troparilとは 意味・読み方・使い方

(–)-2β-Carbomethoxy-3β-phenyltropane (Troparil, WIN 35,065-2, β-CPT) is a stimulant drug used in scientific research. CPT is a phenyltropane based dopamine reuptake inhibitor (DRI) and is derived from methylecgonidine. Troparil is documented to be a few times more potent than cocaine as a dopamine reuptake inhibitor, but is less potent as a serotonin reuptake inhibitor, and has a duration spanning a few times longer, since the phenyl ring is directly connected to tropane through a non-hydrolyzable carbon-carbon bond. The lack of an ester linkage removes the local anesthetic action from the drug, so CPT is a pure stimulant. This change in activity also makes CPT slightly less cardiotoxic than cocaine. The most commonly used form of β-CPT is the tartrate salt, but the hydrochloride and naphthalenedisulfonate salts are also available, as well as the free base.
