Huperzine A, in spite of the possible cholinergic side effects, seems to have a wide margin of safety. Toxicology studies show huperzine A to be non-toxic even when administered at 50-100 times the human therapeutic dose. The extract is active for 6 hours at a dose of 2 μg/kg with no remarkable side effects.
Lycorine has many derivatives used for anti-cancer research such as lycorine hydrochloride (LH) which is a novel anti-ovarian cancer agent, and data has shown that LH effectively inhibited mitotic proliferation of Hey1B cells with very low toxicity. This drug could be used for effective anti-ovarian cancer therapy in the future. [16]

In the treatment of organophosphate toxicity, cholinesterase reactivators such as Pralidoxime reactivate inhibited AChE at peripheral nicotinic receptors.Since AChE mediates effects on both nicotinic and muscarinic receptors, cholinesterase reactivators are co-administered with muscarinic antagonists, primarily atropine.
Huprine X is a synthetic cholinergic compound developed as a hybrid between the natural product Huperzine A and the synthetic drug tacrine.It is one of the most potent reversible inhibitors of acetylcholinesterase known, with a binding affinity of 0.026nM, [1] as well as showing direct agonist activity at both nicotinic and muscarinic acetylcholine receptors.
Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
