N-Desmethyl galanthamine is a plant alkaloid that is found in the Huperzia serrata plant. It has been shown to have cholinergic activity and calcium binding properties. N-Desmethyl galanthamine inhibits acetylcholinesterase, an enzyme responsible for the breakdown of acetylcholine, which is a neurotransmitter. This inhibition leads to increased levels of acetylcholine, which results in increased neuron stimulation and improved memory function. N-Desmethyl galanthamine also binds to β2 nicotinic receptor sites and blocks the binding of nicotine, leading to decreased nicotine dependence.

Carbendazim is a fungicide that inhibits the growth of fungi and bacteria. It has been shown to be potent inducers of polymerase chain reaction (PCR) amplification, with a rate constant of 0.0103 per minute. Carbendazim also has a significant effect on electrochemical impedance spectroscopy (EIS). The EIS analysis was used to compare carbendazim-treated cells with untreated cells, which showed that carbendazim causes an increase in the resistance across the cell membrane. This research suggests that carbendazim may be genotoxic, as it increased the amount of DNA damage observed in wild-type strains and altered the optical properties of DNA. Carbendazim is also an effective inhibitor of nitrite ion oxidation and colloidal gold deposition, which has led to its use as a water vapor control agent for plants.

Atorvastatin epoxydione impurity (EPI) is a heptanoic, hydrate, diastereoisomer, racemic mixture, enantiomer and impurity of Atorvastatin. The EPI has been minimized in the formulation process by using a novel synthesis route that employs a chiral pyrrole derivative as an intermediate. This minimization has allowed for the elimination of the tautomer and other impurities present in the original compound.
