Additional Information

 Information about this agent
The epothilones are a new class of cytotoxic molecules identified as potential chemotherapeutic drugs. As of September 2008[update], epothilones A to F have been identified and characterised. Early studies in cancer cell lines and in human cancer patients indicate superior efficacy to the taxanes. Their mechanism of action is similar, but their chemical structure is simpler. Due to their better water solubility, cremophors (solubilizing agents used for paclitaxel which can affect cardiac function and cause severe hypersensitivity) are not needed. Endotoxin-like properties known from paclitaxel, like activation of macrophages synthesizing inflammatory cytokines and nitric oxide, are not observed for epothilone B. Epothilones were originally identified as metabolites produced by the myxobacterium Sorangium cellulosum. see http://en.wikipedia.org/wiki/Epothilone.
Clinical trials about Epotilones:
 Several epothilone analogs are currently undergoing clinical development for treatment of various cancers. One analog, ixabepilone, was approved in October 2007 by the United States Food and Drug Administration for use in the treatment of aggressive metastatic or locally advanced breast cancer no longer responding to currently available chemotherapies.  In November 2008, the EMEA has refused a marketing authorisation for Ixabepilone.  Epothilone B has proven to contain potent in vivo anticancer activities at tolerate dose levels in several human xenograft models.  As a result, epothilone B and its various analogues are currently undergoing various clinical phases (patupilone [EPO906] and sagopilone [SH-Y03757A, ZK-EPO, chemical structure] are in phase II trials; BMS-310705 and BMS-247550 in phase I trials). Results of a phase III trial with ixabepilone in combination with capecitabine in metastatic breast cancer have been announced. see http://en.wikipedia.org/wiki/Epothilone.
