Alkaloids

Koumine

(1358-76-5)
Koumine is an alkaloid separated from Gelsemium elegans, shows potent anti-tumor activity. Koumine up-regulates the Bax/Bcl-2 ratio and caspase-3 expression in human breast cancer cells[1]. Koumine has anxiolytic, antistress, antipsoriatic, and analgesic activities[3], protects against the development of arthritis in Rheumatoid arthritis (RA) animal models[2].

Corynoxine

(6877-32-3)
Corynoxine is an enantiomer of Corynoxine B; induces autophagy in different neuronal cell lines, including N2a and SHSY-5Y cells.IC50 value:Tareget: Autophagy inducerIn vivo, Cory promotes the formation of autophagosomes in the fat bodies of Drosophila. By inducing autophagy, Cory promotes the clearance of wild-type and A53T α-syn in inducible PC12 cells. Interestingly, different from its enantiomer Cory B, Cory induces autophagy through the Akt/mTOR pathway as evidenced by the reduction

Seneciphylline

(480-81-9)
Seneciphylline is a toxic pyrrolizidine alkaloid in Senecio plants[1]. Seneciphylline significantly increases the activities of epoxide hydrase and glutathione-S-transferase but causes reduction of cytochrome P-450 and related monooxygenase activities[2].

Canadine

(5096-57-1)
(S)-(-)-Canadine is a protoberberine alkaloidwhich potently block functional KATP channels natively expressed on midbrain dopamine neurons. Canadine is used for treatment of degenerative diseases or conditions associated with KATP channel signaling. (S)-(-)-Canadine has a strong central nervous system-depressing activity and is used in the preparation of tetrahydroprotoberberine derivatives as new antipsychotic agents.

Alkaloids exist in nature (mainly plants, but some also exist in animals), a type of nitrogen-containing basic organic compounds, which have alkaloid-like properties. According to the basic structure of alkaloids, it can be divided into about 60 categories. Main types: organic amines, pyrrolidines, pyridines, isoquinolines, indoles, scopolamines, imidazoles, quinazolones, purines, steroids, diterpenes, and others.
