Epothilone D Chemical Properties,Usage,Production
Description
Epothilones are microtubule-stabilizing agents with potential anti-neoplastic actions. They are natural macrolides that have high potency in both taxane-sensitive and taxane-resistant models. Epothilone D is a desoxy form of epothilone B (Item No. 10924) that inhibits the growth of a variety of cancer cells both in vitro (IC50 values range from 0.97 to 21 nM) and in mice. Epothilone D is brain penetrant and reduces neurodegeneration in aged tau transgenic mice. Effects include improved axonal transport, decreased tau neuropathology, and reduced hippocampal neuron loss. Epothilone D also rescues microtubule defects and attenuates nigrostriatal degeneration in a mouse model of Parkinson’s disease.

Uses
Epothilones are polyketide natural products that inhibit cancer cells by a mechanism similar to paclitaxel, and also are effective against paclitaxel-resistant tumours. Epothilone D is in phase I clinical testing of in patients with advanced solid tumours. Epothilone D is a cytotoxic macrolide that stabilises malignant cells'' microtubules and arrests mitosis, a characteristic it shares with other epothilones. They bind to the same hepatic sites as does paclitaxel (Taxol) in a 1:1 stoichiometric ratio of a, b-tubulin heterodimers.
Definition
ChEBI: An epithilone that is epithilone C in which the hydrogen at position 13 of the oxacyclohexadec-13-ene-2,6-dione macrocycle has been replaced by a methyl group.
in vitro
epothilone d is a more potent microtubule stabilizer in vitro than epothilone a or b. in vitro, epothilone d showed potent cytotoxicity in a panel of human tumor cell lines, with similar potency to paclitaxel. it also showed definite advantage over paclitaxel in drug-resistant cell lines, and retained its cytotoxicity against a multidrug resistant cell line over-expressing p-glycoprotein [1].
in vivo
in vivo, antitumor efficacy of epothilone d has been observed in both paclitaxel sensitive and resistant xenografts, as well as certain multidrug resistant xenografts including a doxorubinresistant ccrf-cem leukemic cell xenograft [1].
target
Tubulin
IC 50
2.9 nm for mcf-7 cell line; 2.7 nm for kb-31 cell line; 9.5 nm for ccrf-cem cell line
