This product (cas 155742-64-6) is an intermediate of aprepitant. Aprepitant was the first neurokinin approved by the US FDA in 2003. (NK-1) receptor blocker, which blocks the action of substance P by binding to the NK-1 receptor (mainly present in the central nervous system and its periphery). This product can cross the blood-brain barrier and occupy the NK-1 receptor in the brain. It has selectivity and high affinity, and has a high affinity for NK. 2 and NK-3 receptor affinity is very low. At the same time, this product has a low affinity for the targets of other drugs (such as dopamine receptors, 5 HT receptors) for the treatment of chemotherapy-induced nausea and vomiting symptoms.
