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 Penangkapan bagian G2/M Dan mitotic disaster in quickly proliferating cells. Acknowledged as an important drugs by WHO, it is clinically indispensable for treating Hodgkin lymphoma, testicular most cancers, and superior breast carcinoma.

11. Tanya Jawab
Q1: Can vinblastine be used as a dietary complement?
A: Completely not. Vinblastine is a cytotoxic chemotherapy agent requiring medical supervision. Self-administration is life-threatening.
Q2: How does nattokinase examine for kidney well being?
A: Nattokinase lacks scientific proof for nephroprotection. Vinblastine might trigger nephrotoxicity at excessive doses. Neither compound is indicated for renal situations.
Q3: Why is vincristine impurity management crucial?
*A: Vincristine causes extreme neurotoxicity at microgram doses. Our UPLC-PDA methodology detects ≤0.01% impurity.*
