Glutathione depletion by L-buthionine sulfoximine antagonizes taxol cytotoxicity.
Taxol is a naturally occurring chemotherapeutic agent that is active against a variety of tumors. Taxol is believed to act by binding tightly to microtubules and preventing their disaggregation. Others have shown that depletion of cellular glutathione results in the disaggregation of microtubules, presumably by allowing the oxidation of some or all of the cysteine residues in tubulins. We studi...
متن کاملButhionine sulfoximine diverts the melanogenesis pathway toward
23 Buthionine sulfoximine (BSO) is a specific inhibitor of γ-glutamylcysteine synthetase, thus 24 blocking the synthesis of glutathione (GSH). It is known that this makes that BSO affects melanin 25 synthesis because of the role of thiols in melanogenesis. However, BSO may also react with the 26 intermediate oxidation products of melanogenesis, a possibility that has not been investigated from ...
متن کاملRadiation survival parameters of antineoplastic drug-sensitive and -resistant human ovarian cancer cell lines and their modification by buthionine sulfoximine.
The optimum integration of chemotherapy and irradiation is of potential clinical significance in the treatment of ovarian cancer. A series of human ovarian cancer cell lines have been developed in which dose-response relationships to standard anticancer drugs have been determined, and the patterns of cross-resistance between these drugs and irradiation have been established. By stepwise incubat...
متن کاملMethotrexate delivery via folate targeted dendrimer-based nanotherapeutic platform.
This paper provides a synopsis of the advancements made in advancing a dendrimer-based nanomedicine towards human clinical trials by the Michigan Nanotechnology Institute for Medicine and Biological Sciences. A brief description of the synthesis and characterization of a targeted multifunctional therapeutic will demonstrate the simple yet delicate task of producing novel chemotherapeutic agents...
متن کاملPhase I study of continuous-infusion L-S,R-buthionine sulfoximine with intravenous melphalan.
BACKGROUND Increased intracellular glutathione has long been associated with tumor cell resistance to various cytotoxic agents. An inhibitor of glutathione biosynthesis, L-S,R-buthionine sulfoximine (BSO), has been shown to enhance the cytotoxicity of chemotherapeutic agents in vitro and in vivo. We performed a phase I study of BSO administered with the anticancer drug melphalan to determine th...
