Mitotic Block of Human Blood Cells by Vinca herbacea, Catharanthus roseus and Colchicine Alkaloids
Catharanthus roseus (L.) G.Don is a plant which produces anticancer and anti-mitotic indole alkaloids. Colchicine is an anti-mitotic drug. Anti-mitotic effects of Vinca herbacea Waldst. & Kit. indole alkaloids is unknown. The study were evaluated the antimitotic effect of alkaloids of V. herbacea, Catharanthus roseus andcolchicineon mitosis and microtubule arrangement of human blood cells. In t...
متن کاملNegative-pressure cavitation extraction of four main vinca alkaloids from Catharanthus roseus leaves.
In the present study, an improved method termed negative-pressure cavitation extraction (NPCE) followed by reverse phase high-performance liquid chromatography (RP-HPLC) was developed for the extraction and quantification of vindoline (VDL), catharanthine (CTR), vincristine (VCR) and vinblastine (VLB) from Catharanthus roseus leaves. The optimized method employed 60-mesh particles, 80% ethanol,...
متن کامل5-Methyltryptophan resistant cells of Catharanthus roseus.
Several cell lines resistant to 5-methyltryptophan were selected from wild type cells of different Catharanthus roseus suspension cultures. The resistant cells had up to 30 times the normal levels of free tryptophan. Despite the increased pool size of tryptophan anthranilate synthetase activity of resistant cells was as sensitive to inhibition by L-tryptophan as wild type cells. The overproduct...
متن کاملThe seco-iridoid pathway from Catharanthus roseus
The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum of high-value pharmacological and insect-repellent activities. Vinblastine and vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels, leading to high market prices and poor availab...
متن کاملThe Role of the Alkaloids of Catharanthus Roseus (l.) G.don (vinca Rosea) and Their Derivatives in Cancer Chemotherapy
The search for useful foodstuffs, dyes, medicinal agents, and other materials from plants, animals, or minerals is as old as civilization itself. It should not be surprising, therefore, to learn that all pharmacological prototypes originate from one of these three kingdoms. The alkaloids, nitrogen-containing plant bases, notwithstanding the advent of antibiotics and many valuable synthetic drug...
