Biotransformation of some ring A and B epoxy steroids by the fungus Mucor plumbeus
The preparation of some ring A and B epoxy steroids derived from testosterone, pregnenolone and epiandrosterone using m-chloroperbenzoic acid is described. The biotransformation of the epoxy products by the fungus Mucor plumbeus are performed. The introduction of the epoxy group into the steroids moiety has affected the biotransformation results and gave only hydrolyzed products.
متن کاملSynthesis and Biotransformation of Some Halogenated Steroids by the Fungus Mucor plumbeus
Preparation of some chloro, bromo and iodo steroids derived from testosterone and epiandrosterone is described. The biotransformation of halogenated products by fungus mucor plumbeus are preformed. Introduction of the halogen atom into the steroids moiety severely affected the biotransformation results. Keyword: Mucor plumbeus, biotransformation, steroids, 3dibromomethylene-5α-androstan-17-one....
متن کاملMicrobial transformation of the diterpene mulin-11,13-dien-20-oic acid by Mucor plumbeus.
Two new mulinane-type derivatives: 16-hydroxy mulin-11,13-dien-20-oic (2) acid and 7alpha,16-dihydroxy mulin-11,13-dien-20-oic (3) acid were obtained by microbial transformation of mulin-11,13-dien-20-oic acid (1), along with tyrosol (4) using liquid cultures of Mucor plumbeus. The latter compound has not been previously identified in the genus Mucor. Structural elucidation of these metabolites...
متن کاملBiotransformation of a cage-like diels-alder adduct and derivatives by Mucor ramosissimus samutsevitsch
The present study aimed to evaluate the ability for biotransformation of the Diels-Alder adduct tricyclo[6.2.1.0(2,7)]undeca-4,9-dien-3,6-dione (1) and two synthetic derivatives by the saprobe fungus Mucor ramosissimus Samutsevitsch. Products from oxidation, isomerization and, regioselective and enantioselective reduction were achieved.
متن کاملSimulation of the Evt Model with Copula Functions
The literature has earlier examples that pointed out the weaknesses in traditional Monte Carlo simulations in modelling electricity prices. For example, Lucia and Schwartz (2002) applied EVT to electricity prices to assess the level of tail fatness in series followed by comparison of the Monte Carlo simulation results based on Gaussian and student-t distributions. Their simulation results impro...
