St. Jude Reference #SJ-06-0006
Researchers at St. Jude have generated a human carboxylesterase that efficiently activates the anticancer drug CPT-11. This was performed using site directed mutagenesis of hCE1 using information provided by the crystal structures of wildtype hCE1 and a rabbit liver CE (rCE).
Previous research developed enzyme/prodrug therapy approaches using rCE and CPT-11, this novel enzyme (hCE1mut6), would replace the rabbit protein in these studies and be much more likely to be used in any clinical application of this technology.
