Alkaloids Library

547 compounds

Alkaloids are a large and complex group of cyclic compounds that contain N. About 2,000 different alkaloids have been isolated. Important alkaloids include morphine, strychnine, atropine, colchicine, ephedrine, quinine, and nicotine. Alkaloids are useful as diet ingredients, supplements, and pharmaceuticals, in medicine and in other applications in human life. They showed anti-inflammatory, anticancer, analgesics, local anesthetic and pain relief, neuropharmacologic, antimicrobial, antifungal, and many other activities. Alkaloids are also important compounds in organic synthesis for searching new semisynthetic and synthetic compounds with possibly better biological activity than parent compounds.

MCE designs a unique collection of 547 alkaloids that all come from natural products. MCE Alkaloids Library is a useful tool for drug discovery that can be used for high throughput screening (HTS) and high content screening (HCS).
