Vinca Alkaloids

A group of powerful CYTOTOXIC (anticancer) drugs used to treat acute LEUKAEMIA, LYMPHOMA and some solid tumours such as breast and lung cancers. Originally derived from the periwinkle plant, the latest vinca alkaloid (VINORELBINE) is a semi-synthetic drug. These alkaloids, which are given intravenously, have potentially serious side-effects on the nervous system and also suppress the production of MYELOID cells in the bone marrow.... vinca alkaloids

Vinca Minor

Linn.

Family: Apocynaceae.

Habitat: Grown in Indian gardens as an ornamental.

English: Lesser Periwinkle.

Action: Astringent and circulatory stimulant (contain alkaloid vin- camine). Used for gastric catarrh, chronic dyspepsia; restlessness, headache, dizziness, and for the prevention of premature aging of brain cells, as a geriatic support.

The herb contains indole alkaloids (0.15-1.4%). The major constituent in vincamine; others include vinic, apovincamine, vincadifformin.

Vincamine is hypotensive; increases blood flow and oxygen supply to the brain. The vincamine content in the herb is low and fluctuates greatly. Overdose of the extract brings about a severe drop in blood pressure.

Vincamine, as a pure substance is available for therapeutic administration.... vinca minor

Vinca Rosea

Linn.

Synonym: Catharanthus roseus (Linn.) G.Don.

Family: Apocynaceae.

Habitat: Native of West Indies; commonly grown in Indian gardens.

Ayurvedic: Sadaapushpaa, Sadam- pushpa, Nityakalyaani, Sadaaba- haar.

Siddha: Nithiya kalyani, Sudukadu mallikai.

Action: Cytotoxic.

Over one hundred monomeric and bisindole alkaloids have been isolated.

The indole alkaloid, vincamine, is a vasodilator; the bisindole alkaloids vinblastine and vincristine proved to be highly effective as cancer chemothera- peutic agents.

Vinblastine and vincristine are clinically used in a number of thrombo- cytopenic disorders, such as refractory idiopathic thrombocytopenic purpurea and haemolytic anaemia.

Vinblastine in combination with other chemotherapeutic agents (cis- platin and bleomycin) is used for the treatment of metastatic testicular cancer; also against bladder cancer, breast cancer, non-small cell lung cancer and Hodgkin's lymphoma in combination with other drugs.

Vincristine, in various combinations, is highly effective in acute leukemia in children and lymphocytic leukemia; and pediatric tumours. (The Treatise on Indian Medicinal Plants.)... vinca rosea
