Emoxypine (ethylmethylhydroxypyridine) succinate (MEXIDOL®) is a 3-hydroxypyridine derivative which is quite similar in structure to Vitamin B6 (pyridoxine). The most important components of the mechanism of action of Mexidol® are its antioxidant and membranotropic effects, the ability to modulate functioning of receptors and membrane-bound enzymes, restore a neurotransmitter balance. Due to its mechanism of action Mexidol® has a wide range of pharmacological effects, realized on at least two levels – neuronal and vascular. It has antihypoxic, anti-ischemic, neuroprotective, nootropic, vegetotrophic, anti-stress, anxiolytic, anticonvulsant, anti-alcohol, cardioprotective, anti-atherogenic, geroprotective and other actions. Under the action of Mexidol®, it is observed an improvement in cerebral circulation and microcirculation. Emoxypine is distributed in Russia but it is widely unknown in other regions.

Bisbenzimide ethoxide is a fluorescent nucleic acid stain useful for DNA labeling in fluorescence microscopy and flow cytometry. It appears to bind to AT-rich regions containing at least four such basepairs. Bisbenzimide ethoxide seems to bind relatively poorly to nucleotide sequences containing the alternating step TpA. Bisbenzimide ethoxide induced apoptosis in the HL-60 cells in a time- and dose-dependent manner. Endogenous nuclear topoisomerase I activity in HL-60 cells was inhibited by treatment with Bisbenzimide ethoxide.

Harmaline is a fluorescent psychoactive indole alkaloid from the group of harmala alkaloids and beta-carbolines. It is a partially hydrogenated form of harmine. Harmaline is produced by various plants including Peganum harmala aswell as Banisteriopsis caapi. Harmaline has been investigated as an anti-cancer agent and for the treatment of dementia in rats. However, Harmaline is known to induce tremors in rats.
