Abstract:
Provided herein are steroidal compounds that are androsta-5,7-dienes or a pregna-5,7-dienes and ultraviolet B (UVB) conversion products thereof which includes pharmaceutical compositions of the steroidal compounds. Also provided is a method for producing hydroxylated metabolites of cholecalciferol via the P450scc (CYPl IA 1) or CYP27B 1 enzyme systems and the hydroxylated metabolites so produced. In addition, a method for inhibiting proliferation of either a normally or abnormally proliferating cell by contacting the cell with any of the compounds described herein. A related method is provided of treating a condition associated with the proliferating cell such as a cancer, a skin disorder, a defect in cell differentiation, cosmetic, prophylaxsis, or healthy cell maintenance.
Abstract:
Provided herein is an enzymatic method of producing hydroxylated ergosterols and hydroxylated ergocalciferols using the cytochrome P450scc enzyme and/or the CYP27B1 enzyme and the hydroxylated compounds so produced. Also provided are methods of using the hydroxylated ergosterols and hydroxylated ergocalciferols to treat a tumor or other pathophysiologic condition.
Abstract:
Provided herein are enzymatic methods of producing steroid compounds S such as 7-dehydropregnenolone, hydroxy derivatives thereof and vitamin D2- and D3- like compounds and derivatives thereof. Also provided are the derivatives of the vitamin D3-like compounds so generated via the action of cytochrome P450scc enzyme on substrates 7-dehydrocholesterol, vitamin D2 or vitamin D3.
