Abstract
Attempted synthesis of testosterone glucuronide using commercial UDP-glucuronyl transferase from either bovine or ovine sources was unsuccessful, giving 2–5% yields. This low yield was due to contaminating β-glucuronidase which hydrolysed the product. Limitation of glucuronidase activity using improved pH control and inhibitors, plus optimisation of other reaction conditions, increased the yield to 20–30% with the ovine enzyme and allowed practical preparative synthesis.
