Bacterial CYP154C8 catalyzes carbon-carbon bond cleavage in steroids

Here, we report the first bacterial cytochrome P450, CYP154C8, that catalyzes the C–C bond cleavage reaction of steroids. A major change in product distribution is observed with CYP154C8, when the reactions are supported by NADPH and spinach redox partners ferredoxin and ferredoxin reductase, compared with previously reported reactions supported by NADH and redox partners containing putidaredoxin and putidaredoxin reductase. The NMR-based structural elucidation of reaction products reveals 21-hydroxyprednisone as the major product for prednisone, while the other product is identified as 1-dehydroadrenosterone obtained due to C–C bond cleavage. A similar pattern of product formation is observed with cortisone, hydrocortisone, and prednisone. The reaction catalyzed by CYP154C8 in the presence of oxygen surrogates also prominently shows the formation of C–C bond cleavage products.

Electrochemically Enabled One-Pot Multistep Synthesis of C19 Androgen Steroids

The synthesis of many valuable C19 androgens can be accomplished by removal of the C17 side chain from more abundant corticosteroids, followed by further derivatization of the resulting 17-keto derivative. Conventional chemical reagents pose significant drawbacks for this synthetic strategy, as large amounts of waste are generated, and quenching of the reaction mixture and purification of the 17-ketosteroid intermediate are typically required. Herein, we present mild, safe, and sustainable electrochemical strategies for the preparation of C19 steroids. A reagent and catalyst free protocol for the removal of the C17 side chain of corticosteroids via anodic oxidation has been developed, enabling several one-pot, multistep procedures for the synthesis of androgen steroids. In addition, simultaneous anodic C17 side chain cleavage and cathodic catalytic hydrogenation of a steroid has been demonstrated, rendering a convenient and highly atom economic procedure for the synthesis of saturated androgens.

Steroid transformations with Exophiala jeanselmei var. lecanii-corni and Ceratocystis paradoxa

The fungi Exophiala jeanselmei var. lecanii-corni [IMI (International Mycological Institute) 312989, UAMH (University of Alberta Microfungus Collection and Herbarium) 8783] and Ceratocystis paradoxa (IMI 374529, UAMH 8784) have been examined for their potential in steroid biotransformation. The study has determined that E. jeanselmei var. lecanii-corni effected overall anti-Markovnikov hydration on dehydroisoandrosterone, and side-chain degradation on a variety of pregnanes. Both ascomycetes were found to carry out redox reactions of alcohols and ketones as well as 1,4 reduction of α,β-unsaturated carbonyl systems.
