Central nervous system injury, specifically traumatic brain and spinal cord can have significant long lasting effects. There are no comprehensive treatments to combat the injury sequalae of events that occurring following a central trauma. Herein we discuss potential for epothilone family microtubule stabilizing agents improve outcomes experimentally induced These drugs, which able cross blood-...
The synthesis of two deoxygenated analogues of potent epothilones is reported in an effort to analyze the relative importance of molecular conformation and ligand-target interactions to biological activity. 7-deoxy-epothilone D and 7-deoxy-(S)-14-methoxy-epothilone D were prepared through total synthesis and shown to maintain the conformational preferences of their biologically active parent co...
Microtubules are unique cytoskeletal structures that have structural subunits of αβ tubulin. Taxol is a typical microtubule stabilizing drug. The epothilones are other natural products with similar mechanism of action totaxol. Despite the highly conserved nature of β-tubulin, some organism like Saccharomyces cerevesia (S.cerevesia) is resistance to taxol, but sensitive to epothilones. In order ...
Epothilones in epithelial ovarian, fallopian tube, or primary peritoneal cancer: a systematic review
The epothilones are a group of novel microtubule-targeted, antimitotic compounds that have a paclitaxel-like, assembly enhancing effect on tubulin in vitro as well as in cultured cells. We hypothesize that epothilones induce mitotic arrest by suppressing microtubule dynamics. To test this hypothesis, we used MCF7 cells stably transfected with GFP-alpha-tubulin to analyze microtubule dynamics at...
Sagopilone (ZK-EPO) is the first fully synthetic epothilone undergoing clinical trials for the treatment of human tumors. Here, we investigate the cellular pathways by which sagopilone blocks tumor cell proliferation and compare the intracellular pharmacokinetics and the in vivo pharmacodynamics of sagopilone with other microtubule-stabilizing (or tubulin-polymerizing) agents. Cellular uptake a...
Challenges in the discovery of more potent agents to treat the castration-resistant prostate carcinoma (CRPC) reflect the frustrating condition due to development of its drug-resistance in addition to hormone-refractoriness. Although among the different CRPC therapy modalities, the chemotherapy regimens might seem conceptually outclassed as exhibiting a scant tumor cell-selectivity if compared ...
