Administration of aqueous extracts of V. rosea flower and leaf have been found to regulate the blood sugar level in alloxan diabetic male albino rats. V. rosea therapy not only produced blood glucose homeostasis but also reversed changes in carbohydrate, protein, lipid metabolisms and metabolic and
Deacetylvinblastine (DAVLB) hydrazide, a cytotoxic vinca alkaloid, has been linked to the monoclonal antibody, KS1/4, via aldehyde residues of the oxidized carbohydrate groups on the antibody. The resulting KS1/4-DAVLB hydrazide conjugate is unstable in solution with both the acyl hydrazone linkage
We have shown that a glycoprotein(s) with a molecular weight of approximately 180,000 exists on the surface of cultured lymphoblasts selected for resistance to vinblastine (VLB) (CEM/VLB100). The amount of this glycoprotein, which is barely detectable on the VLB-sensitive cells (CEM), appears to be
During a phase I trial of EC145 (a folate-targeted vinca alkaloid conjugate), constipation was identified as the dose-limiting toxicity, probably from a nonfolate receptor-related liver clearance process capable of releasing unconjugated vinca alkaloid from EC145 and shuttling it to the bile. Here,
A panel of four murine monoclonal antibodies apparently directed against three distinct epitopes of carcinoembryonic antigen (CEA) was conjugated via oxidized carbohydrate groups to 4-desacetylvinblastine-3-carboxyhydrazide. The resulting antibody-vinca conjugates were evaluated for antitumor
A method has been developed to allow the direct coupling of the cytotoxic vinca alkaloid 4-desacetylvinblastine-3-carbohydrazide (DAVLB hydrazide) to a variety of murine monoclonal antibodies directed against human solid tumors. Periodate oxidation of carbohydrate residues on the antibodies,
