2CLisaB
2CLisaB, also known as 2--1,2,3,4-tetrahydroisoquinoline, is a serotonin receptor modulator of the phenethylamine, 2C, and N-benzylphenethylamine families. It is a cyclized phenethylamine analogue of the serotonergic psychedelic 25B-NBOMe in which the N-benzyl group has been cyclized with the amine to form a tetrahydroisoquinoline ring. The drug shows affinity for the serotonin 5-HT2A and 5-HT2C receptors. 2CLisaB was first described in the scientific literature by Michael Robert Braden of the lab of David E. Nichols at Purdue University in 2007.
The compound without the 4-bromo substitution is known as 2CLisaH. It shows much lower affinities for the serotonin 5-HT2A and 5-HT2C receptors.
