Vinblastine Sulfate: The Vinca Alkaloid Powerhouse in Most cancers Therapeutics | Supplier & Manufacturer
1. What is Vinblastine?
Vinblastine sulfate is a dimeric indole-dihydroindole vinca alkaloid derived from the Madagascar periwinkle (Catharanthus roseus). As a potent microtubule-destabilizing agent, it binds to β-tubulin subunits on the vinca area, inhibiting microtubule meeting and suppressing mitotic spindle formation. This triggers G2/M part arrest и mitotic disaster in quickly proliferating cells. Acknowledged as an важные лекарства by WHO, it is clinically indispensable for treating Hodgkin lymphoma, testicular most cancers, and superior breast carcinoma.
