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.
