Nevertheless, considering that serpentine's has: (i) high in vitro potency (IC50 = 0.775 [micro]M) as
acetylcholinesterase inhibitor in comparison with physostigmine (6.45 [micro]M); (ii) a competitive and low affinity interaction with muscarinic receptors ([K.sub.b] = 6.5 [micro]M); and (iii) no neuromuscular nicotinic antagonism up to 100 [micro]M, serpentine may be an interesting lead compound.
