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

A bacterium capable of assimilating 3-chloro-1,2-propanediol was isolated from soil by enrichment culture. The strain was identified as Alcaligenes sp. by taxonomic studies. The crude extracts of the cells had dehalogenating activities and converted various halohydrins to the corresponding epoxides. 3-Chloro-1,2-propanediol was degraded stereospecifically by the strain, liberating Cl-. The residual isomer was found by use of this strain in 38% yield, and (S)-glycidol (99.4% enantiomeric excess) was subsequently synthesized from the obtained (S)-3-chloro-1,2-propanediol by alk. treatment.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 60827-45-4, is researched, SMILESS is OC[C@H](O)CCl, Molecular C3H7ClO2Journal, Article, Research Support, Non-U.S. Gov’t, Experientia called Formation of the active antifertility metabolite of (S)-α-chlorohydrin in boar sperm, Author is Jones, A. R.; Stevenson, D., the main research direction is chlorohydrin metabolism sperm; glycerol chlorohydrin metabolism sperm; enzyme chlorohydrin metabolism sperm.Computed Properties of C3H7ClO2.

Incubation of boar sperm with (S)-α-chlorohydrin (I) [60827-45-4] resulted in formation of (S)-3-chlorolactaldehyde (II) [86747-03-7]. I inhibited the production of 14CO2 when 14C-labeled fructose  [57-48-7] was the substrate but had no effect when 14C-labeled glycerol  [56-81-5] was used. (R,S)-3-Chlorolactaldehyde  [84709-24-0], however, inhibited CO2 formation from glycerol. The oxidation of 14C-labeled glycerol-3-phosphate  [57-03-4] was similarly inhibited by I confirming that the presence of glycerol but not its metabolites prevented the oxidation of I to II. Glycerol reversed the inhibition of fructose metab by I. Addnl., preincubation of sperm with I inhibited glycerol metabolism Apparently, I is metabolized to II in sperm by an enzyme involved in the oxidation of glycerol to glyceraldehyde. The presence of glycerol decreases the activity of this enzyme towards I thereby preventing formation of II, an inhibitor of glyceraldehyde 3-phosphate dehydrogenase  [9001-50-7].

Computed Properties of C9H11Cu. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Carbonylation of a Tetrameric Aryloxocopper(I) Cluster. Author is Lopes, Cesar; Hakansson, Mikael; Jagner, Susan.

Carbonylation of 2,6-diphenylphenoxocopper(I), tetrameric [(CuOC6H3Ph2)4] (1), results in a [{Cu(OC6H3Ph2)(CO)}2] dimer (2). The parent aryl oxide, [(CuOC6H3Ph2)4], which was prepared from mesitylcopper(I) and 2,6-diphenylphenol, has an approx. planar Cu4O4 core, in which Cu(I) is two-coordinated and Cu-O bonds range from 1.834(7) to 1.865(7) Å. Its carbonylation product 2 is a μ2-phenoxo-bridged dimer, containing three-coordinated Cu(I), with longer Cu-O bonds, viz. 1.953(7)-1.995(7) Å. Cu-C bond lengths in 2 are 1.78(1) and 1.79(1) Å, resp., with both carbonyl C-O distances equal to 1.12(1) Å, and Cu-C-O angles of 174(1) and 179(1)°, resp. Carbonyl stretching frequencies in the IR are 2099, 2103, and 2112 cm-1 for the solid and 2102 cm-1 in toluene solution, and the 13C NMR signal (toluene solution) is at 168 ppm. From comparison with other carbonyl complexes of Cu(I), the Cu-C bond is judged to be predominantly of σ character, with minimal metal → ligand π* contribution. Both 1 and 2 retain their aggregation states on dissolution in nonpolar solvents, as ascertained by cryoscopic mol. weight determinations of the compounds in benzene.

The Hedgehog (Hh-) signaling pathway is a key developmental pathway which gets reactivated in many human tumors, and smoothened (Smo) antagonists are emerging as novel agents for the treatment of malignancies dependent on the Hh-pathway, with the most advanced compounds demonstrating encouraging results in initial clin. trials. A novel series of potent bicyclic hydantoin Smo antagonists was reported in the preceding article, these have been resolved, and optimized to identify potent homochiral derivatives with clean off-target profiles and good pharmacokinetic properties in preclin. species. While showing in vivo efficacy in mouse allograft models, unsubstituted bicyclic tetrahydroimidazo[1,5-a]pyrazine-1,3(2H,5H)-diones were shown to epimerize in plasma. Alkylation of the C-8 position blocks this epimerization, resulting in the identification of MK-5710 which was selected for further development.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called The male antifertility activity of 6-chloro-6-deoxyglucose, published in 1991-12-31, which mentions a compound: 60827-45-4, Name is (2S)-(+)-3-Chloropropane-1,2-diol, Molecular C3H7ClO2, Application of 60827-45-4.

6-Chloro-6-deoxy[U-14C]glucose is not metabolized by mature boar spermatozoa nor has it any specific inhibitory action on their metabolic activity in vitro. The compound is metabolized by the male rat and the identification of 2 urinary metabolites as α-chlorohydrin and 3-chlorolactate confirmed that (S)-3-chlorolactaldehyde is produced by this species in vivo. A tissue distribution study revealed that radioactivity from 6-chloro-6-deoxy[U-14C]glucose was more concentrated in rat caudal spermatozoa than in any other of the major tissues.
