Author is Jackson, H.; Rooney, F. R.; Fitzpatrick, R. W.; Gibson, K. H..

In male rats, a single oral dose of S(+)α-chlorohydrin (I) [60827-45-4] (12.5 mg/kg) produced temporary infertility following pairing with females from matings between days 2 and 6 after the I dose. A similar dose of the racemic mixture [96-24-2] was ineffective and the antifertility effect of the active isomer was comparable to that produced by a mixture of similar amounts of the S(+)- and R(-) [57090-45-6]-isomer or the corresponding dose of the racemate (25 mg/kg). However, the latter dose of the S(+)-isomer induced sterility during week 1, some degree of recovery of fertility in weeks 2-3 followed by permanent sterility. The S(+) isomer also maintained the reversible antifertility effect on epididymal spermatozoa at a daily oral dose of 5-10 mg/kg. Preparation of derivatives of I may provide compounds with high antifertility potency and low toxicity.

Author is Suzuki, Toshio; Kasai, Naoya; Yamamoto, Ryoichi; Minamiura, Noshi.

A bacterium that assimilates (S)-3-chloro-1,2-propanediol [monochlorohydrin (MCH)] was isolated from soil by enrichment culture. The bacterium was identified as Pseudomonas sp. by taxonomic studies. The strain grew in a medium containing racemic MCH as a source of carbon and degraded (S)-MCH stereoselectively, liberating chloride ions. The residual isomer was the (R)-form [99.5% enantiomeric excess (ee)], which was obtained from the racemate in a final yield of 36% by using this strain. Subsequently, highly optically active (R)-glycidol (GLD) (99.3% ee) was prepared from the (R)-MCH obtained by reaction in alk. solution The cell-free extracts of the cells had both dehalogenating and epoxide-opening activities, which converted various halohydrins to the corresponding epoxides and epoxides to the corresponding diols, resp.

In addition to the previously known A-rac and B-rac polymorphs of the chiral drug metaxalone 1, an enantiopure A-(S)-form was obtained and studied. According to x-ray anal., the crystalline organization of this form is close to the A-rac-1 polymorph. Crystallization of metaxalone melts is accompanied by the formation of a previously unknown metastable C-phase, which in the case of both racemic and enantiomeric samples are transformed into A-rac-1 or A-(S)-1. Anal. of the PXRD and IR spectra of crystalline samples revealed a similarity of the internal structure for the A-(S)-1, A-rac-1, C-(S)-1, and C-rac-1 crystalline forms and the essential difference of all of these phases from the B-rac-1 phase. According to the thermochem. data, the dependences of the change in the Gibbs free energy for all the phases studied are plotted in the interval from the m.p. to 20°. Under standard conditions, the crystalline modifications of metaxalone, relative to ΔG0, form such a series: B-rac-1 < A-(S)-1 ≈ A-rac-1 < C-rac-1 < C-(S)-1. A model that describes all the exptl. revealed features of metaxalone crystallization is proposed.
