Synthesis of (±)-10,10-dimethylhuperzine A — a huperzine analogue possessing a slower enzyme off-rate
摘要:
The synthesis of (+/-)-10,10-dimethylhuperzine A is reported together with its kinetic (k(on) and k(off)) and dissociation constants for the inhibition of fetal bovine serum acetylcholinesterase. While somewhat more potent than (+/-)-huperzine A, the dimethyl analogue shows a slower off-rate from AChE, a result that may be of potential therapeutic value.
