Epothilone D – correct drug, wrong disease

Correct Diagnosis, Wrong Medication, Unusual Adverse Event

A 37 year old white woman with a well-known history of migraine headaches presented to an urgent care center with a chief complaint of severe headache with associated nausea that was unrelieved by medication that she had at home. She had taken Axert® (almotriptan) at home and repeated it once, without any improvement in her symptoms; she typically had good results with this medication. Upon pre...

Highly Efficient CYP167A1 (EpoK) dependent Epothilone B Formation and Production of 7-Ketone Epothilone D as a New Epothilone Derivative

Since their discovery in the soil bacterium Sorangium cellulosum, epothilones have emerged as a valuable substance class with promising anti-tumor activity. Because of their benefits in the treatment of cancer and neurodegenerative diseases, epothilones are targets for drug design and pharmaceutical research. The final step of their biosynthesis - a cytochrome P450 mediated epoxidation of epoth...

Stabilized Polymer Micelles for the Development of IT-147, an Epothilone D Drug-Loaded Formulation

Epothilones have demonstrated promising potential for oncology applications but suffer from a narrow therapeutic window. Epothilone D stabilizes microtubules leading to apoptosis, is active against multidrug-resistant cells, and is efficacious in animal tumor models despite lack of stability in rodent plasma. Clinical development was terminated in phase II due to dose limiting toxicities near t...

Thalidomide in small cell lung cancer: wrong drug or wrong disease?

Design, synthesis and biological evaluation of bridged epothilone D analogues.

Six epothilone D analogues with a bridge between the C4-methyl and the C12-methyl carbons were prepared in an attempt to constrain epothilone D to its proposed tubulin-binding conformation. Ring-closing metathesis (RCM) was employed as the key step to build the C4-C26 bridge. In antiproliferative assays in the human ovarian cancer (A2780) and prostate cancer (PC3) cell lines, and also in tubuli...
