Asymmetric total synthesis and identification of tetrahydroprotoberberine derivatives as new antipsychotic agents possessing a dopamine D1, D2 and serotonin 5-HT1A multi-action profile
An effective and rapid method for the microwave-assisted preparation of the key intermediate for the totalsynthesis of tetrahydroprotoberberines (THPBs) including l-stepholidine (l-SPD) was developed. Thirty-one THPB derivatives with diverse substituents on A and D ring were synthesized, and their binding affinity to dopamine D1, D2 and serotonin 5-HT1A and 5-HT2A receptors were determined.

The present disclosure relates to a compound of Formula I or a non-toxic pharmaceutically acceptable salt thereof, wherein each R1, R2, R3, and R4 is independently selected from methyl (-CH3) and trideuteromethyl (-CD3), at least one of R1, R2, R3, and R4 is selected from trideuteromethyl (-CD3).
The compound is a deuterated derivative of L-tetrahydropalmatine, which not only markedly improves pharmacological effects, but also significantly reduces cardiac side effects, liver toxicity, and remarkably decreases individual differences.
