Methods and systems for evaluating and predicting the reactivity of natural and engineered monooxygenase enzymes are provided. Methods are provided for acquiring a functional profile (fingerprint) of monooxygenases that encode information regarding the active site configuration of such monooxygenases. Methods are also provided for carrying out analysis of a monooxygenase fingerprint, to formulate predictions regarding the reactivity properties (e.g., substrate reactivity, chemo-, regio, and stereoselectivity properties) of the fingerprinted monooxygenases.

A novel ketone derivative of artemisinin, artemisitone-9, was produced by the biotransformation of cultured Streptomyces griseus ATCC 13273. The structure of the ketone product Was fully elucidated by various spectroscopic techniques, and the mechanism of generating Such novel metabolite is also discussed. (C) 2006 Elsevier Ltd.

Derivatives of the antimalarial agent artemisinin, compositions comprising the derivatives, methods for preparing the derivatives, and their uses in pharmaceutical compositions intended for the treatment of parasitic infections are provided. Methods are provided for the production of artemisinin derivatives via functionalization of positions C7 and C6a, and optionally, in conjunction with modifications at positions C10 and C9, via chemoenzymatic methods. Recombinant cytochrome P450 polypeptides are also provided for use in the methods. The artemisinin derivatives can be used for the treatment of malaria and other parasitic infections, alone or in combination with other antiparasitic drugs.
