Allocryptopine is isoquinoline alkaloid found primarily in the plant families Fumariaceae, Papaveraceae, Berberidaceae, Ranunculaceae, Rutaceae, and Sapindaceae. It have been reported to possess strong antibacterial, anti-inflammatoty, antiparasitic, antineoplastic and anti-addictive activities. Allocryptopine inhibits human acetylcholinesterase and butyrylcholinesterase. It blocks hERG current in HEK293 cells. Allocryptopine strongly enhanced the I(peak) of the T353I channel by enhancing the plasma membrane (PM) expression of Nav1.5 and rescued defective trafficking after co-incubation with HEK293 cells that carry mutation channel 24 h. A possible preparation for the treatment of HIV-1 and HIV-2 viruses containing pharmaceutically effective amounts of allocryptopine has been patented.
