17α, 20α-dihydroxy-4-pregnen-3-one, not its 20β isomer, is produced from 17α-hydroxyprogesterone by spermatozoa of secondary male groupers (Epinephelus tauvina) derived from females implanted with 17α-methyltestosterone

Sperm of secondary male groupers(Epinephelus tauvina), derived from females implanted with 17α-methyltestosterone (MT), were incubated with [3H]17-hydroxyprogesterone for 2 hr. The medium was extracted and analyzed by high performance liquid chromat

Endocrine-disrupting chemicals, known to be present in the environment, have great potential for interfering with reproductive health in wildlife and humans. There is, however, little direct evidence that endocrine disruption has adversely affected f

Publikováno v: Theriogenology. 55(3)

A new integrated approach including computer-assisted sperm analysis (CASA), viability staining and fertilization was used to study the quality of cryodiluents used in fish sperm cryopreservation. As an example the sperm quality of an African catfish

Conformational free energy differences in steroids. Part I. Equilibration of 3β-substituted 5α- and 5β-cholestan-6-ones

Autor: D. Neville Jones, D. E. Kime

Publikováno v: J. Chem. Soc. C. :846-851

Equilibration of 3β-substituted 5α-cholestan-6-ones with their 5β-isomers provided a method for the determination of the conformational free energy difference between an axial and an equatorial 3-substituent. These differences for the hydroxy, ace

Conformational free energy differences in steroids. Part II. Equilibration of 3α-methyl-5α- and -5β-cholestan-6-ones, and of 3α-chloro-5α- and -5β-cholestan-6-ones

Autor: D. Neville Jones, R. Grayshan, D. E. Kime

Publikováno v: J. Chem. Soc. C. :48-54

The conformational preference of the methyl group determined by equilibration of 3α-methyl-5α-cholestan-6-one with its 5β-isomer agreed well with values obtained in other systems. For 3α-chlorine the method is invalidated by electrostatic interac

Conformational free energy differences in steroids. Part III. Equilibration of 3α-hydroxy-, 3α-methoxy-, and 3α-acetoxy-5β-cholestan-6-ones with their 5α-isomers

Publikováno v: J. Chem. Soc. C. :1208-1215

The equilibria mentioned in the title are influenced by electrostatic interactions between the 3α-substituents and the C-6 keto-group, calculated values for which are in accord with the observed effects. Restricted rotation in the axial hydroxy- and
