Catharanthine is a precursor of the anti-tumor drugs vinblastine and vincristine, formed by dimerization of catharanthine with vindoline. Catharanthine itself is an inhibitor of tubulin self-assembly into microtubules, although not so potent as vinblastine or vincristine. Catharanthine also has anticholinergic activity. It showed muscarinic antagonism at 10 microM and fully inhibited nicotinic receptor mediated diaphragm contractions with an IC50 of 59.6 microM.

Catharanthus roseus (L.) G. Don is a plant species known for its production of a variety of terpenoid indole alkaloids, many of which have pharmacological activities. Catharanthine can be chemically coupled to the abundant leaf alkaloid vindoline to form the
We compared the interaction of several catharanthine alkaloids including, ibogaine, vincristine, and vinblastine, with that for the noncompetitive antagonist phencyclidine (PCP) at muscle nicotinic acetylcholine receptors (AChRs) in different conformational states. The results established that catharanthine alkaloids: (a) inhibit, in

Catharanthine content and agronomic traits in major Catharanthus roseus varieties were analyzed. It was found that there existed great difference in catharanthine content and agronomic traits among the varieties. Catharanthine content was the highest in variety Pacifica Polka Dot (PPD)
