What are Catharanthus Alkaloids? Alkaloids: Bitter tasting, nitrogenous compounds that are alkaline in their chemical properties. Catharanthus alkaloids are “the most important plant source of materials used in chemotherapy.” Although there are approximately 130 alkaloids in Catharanthus roseus, there are four major ones in clinical use: Vinblastine Vincristine Vindesine Vinorelbine Alkaloids: Bitter tasting, nitrogenous compounds that are alkaline in their chemical properties.

How are the Catharanthus alkaloids used to treat diseases? Administered intravenously Metabolized by the liver & excreted Work by stopping mitosis of affected cells, thus causing cell death Bind to the tubulin monomers & prevent microtubules from forming so that the chromosomes can ’ t separate (mitosis stops in metaphase) Administered intravenously Metabolized by the liver & excreted Work by stopping mitosis of affected cells, thus causing cell death Bind to the tubulin monomers & prevent microtubules from forming so that the chromosomes can ’ t separate (mitosis stops in metaphase)

The History of Catharanthus roseus The pantropical distribution of C. roseus was caused by sailors Brazilian remedy for hemorrhoids and scabies. Periwinkle was originally studied in the lab as a cure for diabetes, not for cancer. Jamaican Periwinkle tea Supply of leaves was insufficient for research Catharanthus roseus was grown in Canada. Finally, vinblastine was isolated in 1957 in Dr. J.B. Collip ’ s Department of Medical Research at the University of Western Ontario.

DO NOT try eating or smoking rosy periwinkle for “medicinal purposes.” Periwinkle is POISONOUS if smoked or ingested Horrible side effects! Birth defects Neurotoxicity, peripheral neuropathy Loss ofpetite Loss of appetite, nausea, cramps & constipation Fever Amenorrhoea Hair loss Incontinence Mouth ulcers, jaw pain Increased risk of infections Nosebleeds, bleeding gums, bruises Pain and discoloration along vein DO NOT try eating or smoking rosy periwinkle for “medicinal purposes.” Periwinkle is POISONOUS if smoked or ingested Horrible side effects!
