The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (2S)-(+)-3-Chloropropane-1,2-diol(SMILESS: OC[C@H](O)CCl,cas:60827-45-4) is researched.Reference of 5,5′-Dimethyl-2,2′-bipyridine. The article 《The effect of the isomers of α-chlorohydrin and racemic β-chlorolactate on the rat kidney》 in relation to this compound, is published in Chemico-Biological Interactions. Let’s take a look at the latest research on this compound (cas:60827-45-4).

The (R)- [57090-45-6] and (S)-isomers [60827-45-4] of the male antifertility agent α-chlorohydrin have been synthesized. When administered to rats, the (R)-isomer induced a period of diuresis and glucosuria, whereas the (S)-isomer, which possesses the antifertility activity, had no detrimental action on the kidney. Neither of the isomers of α-chlorohydrin nor those of an active analog, 3-amino-1-chloropropan-2-ol, had any inhibitory activity on the oxidative metabolism of glucose  [50-99-7] or lactate  [50-21-5] in isolated kidney tubules. However, (RS)-β-chlorolactate  [1713-85-5], a metabolite common to both compounds, inhibited the oxidation of glucose, lactate, pyruvate  [127-17-3], and glutamate  [56-86-0] to CO2. It is proposed that the antifertility action of the (S)-isomers of α-chlorohydrin and 3-amino-1-chloropropan-2-ol is unrelated to the renal toxicity of the (R)-isomers, a toxic action involving the inhibition of oxidative metabolism by (S)-β-chlorolactate or a further product of this metabolite.

Previously, we reported on the discovery of a novel series of bicyclo[3.1.0]hexane fused thiophene derivatives that serve as potent and selective S1P1 receptor agonists. Here, we discuss our efforts to simplify the bicyclohexane fused thiophene head. In a first step the bicyclohexane moiety could be replaced by a simpler, less rigid cyclohexane ring without compromising the S1P receptor affinity profile of these novel compounds In a second step, the thiophene head was simplified even further by replacing the cyclohexane ring with an iso-Bu group attached either to position 4 or position 5 of the thiophene. These structurally much simpler headgroups again furnished potent and selective S1P1 agonists (e.g., 87), which efficiently and dose dependently reduced the number of circulating lymphocytes upon oral administration to male Wistar rats. For several compounds discussed in this report lymphatic transport is an important route of absorption that may offer opportunities for a tissue targeted approach with minimal plasma exposure.

As far as I know, this compound(60827-45-4)Application of 60827-45-4 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Stereospecific analysis of fatty acid esters of chloropropanediol isolated from fresh goat milk》. Authors are Myher, J. J.; Kuksis, A.; Marai, L.; Cerbulis, J..The article about the compound:(2S)-(+)-3-Chloropropane-1,2-diolcas:60827-45-4,SMILESS:OC[C@H](O)CCl).Product Details of 60827-45-4. Through the article, more information about this compound (cas:60827-45-4) is conveyed.

The fatty acid esters of chloropropanediol isolated from goat milk fat in small quantities were subjected to a stereospecific anal. via phospholipase C and phosphocholine esters as intermediates. Synthetic racemic 1-chloro-2,3-dioleoylpropanediol was prepared by standard methods and was used as a control. The stereospecific analyses were performed following release of the fatty acids from the primary positions of each chloropropanediol diester with pancreatic lipase. The resulting 1-chloro-2-acylpropanediols were then converted into the corresponding phosphocholine derivatives by a stepwise reaction with phosphorus oxychloride and choline chloride. The 1-chloro-2-acyl-3-phosphocholinepropanediols were subjected to hydrolysis with phospholipase C (Clostridium perfringens), which hydrolyzed 50% of the phosphatide within 2 min and the rest of it in 2 h. From previous experience with glycerol esters, it was assumed that the more rapidly hydrolyzed mols. were the sn-1-chloro-2-acylpropanediol derivatives and the more slowly hydrolyzed ones the sn-2-acyl-3-chloropropanediol derivatives Hydrolysis with phospholipase A2 (Crotalus adamanteus) released 50% of the total fatty acid along with the corresponding lyso compound within 10 min, after which there was no further reaction. The hydrolysis products were assayed directly by gas chromatog. or were isolated by TLC prior to quantitation by gas chromatog. Both naturally occurring and synthetic chloropropanediol diesters behaved similarly on stereospecific anal. and were therefore concluded to be racemic.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (2S)-(+)-3-Chloropropane-1,2-diol, is researched, Molecular C3H7ClO2, CAS is 60827-45-4, about Solid Phase Behavior, Polymorphism, and Crystal Structure Features of Chiral Drug Metaxalone.Application of 60827-45-4.

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.

Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 60827-45-4, is researched, Molecular C3H7ClO2, about The action of (S)-α-chlorohydrin and 6-chloro-6-deoxyglucose on the metabolism of guinea pig spermatozoa, the main research direction is chlorohydrin sperm metabolism; chlorodeoxyglucose sperm metabolism; glycolysis sperm chlorohydrin chlorodeoxyglucose; lactate fructose sperm chlorohydrin chlorodeoxyglucose; fructose lactate sperm chlorohydrin chlorodeoxyglucose.Name: (2S)-(+)-3-Chloropropane-1,2-diol.

(S)-α-Chlorohydrin  [60827-45-4] inhibited the conversion of D-fructose  [57-48-7] to lactate  [50-21-5] by mature guinea pig spermatozoa in vitro. At 2 mM, there was a specific inhibition of glyceraldehyde-phosphate dehydrogenase  [9001-50-7], resulting in the accumulation of fructose 1,6-bisphosphate  [488-69-7], dihydroxyacetone 3-phosphate  [57-04-5], and glyceraldehyde 3-phosphate  [591-59-3] and a concomitant decrease in the concentration of endogenous lactate. (R,S)-[3-36Cl]-α-chlorohydrin was metabolized by the spermatozoa to 3-chlorolactaldehyde  [84709-24-0] of unknown configuration. Exogenous (R,S)-3-chlorolactaldehyde  [84709-24-0] (2 mM) was an inhibitor of glyceraldehyde-phosphate dehydrogenase in guinea pig spermatozoa, whereas (R)-α-chlorohydrin  [57090-45-6] (10 mM) had no significant effect on the metabolism of fructose. 6-Chloro-6-deoxyglucose  [40656-44-8] (10 mM) inhibited glyceraldehyde-phosphate dehydrogenase in guinea pig spermatozoa in vitro and was metabolized to 3-chlorolactaldehyde which was presumably the (S)-isomer. The antiglycolytic actions of (S)-α-chlorohydrin and 6-chloro-6-deoxyglucose in guinea pig spermatozoa are probably due to the action of a common metabolite, (S)-3-chlorolactaldehyde  [86747-03-7].

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 Optical isomers of chloropropanols: Mechanisms of their formation and decomposition in foods, published in 2002, which mentions a compound: 60827-45-4, Name is (2S)-(+)-3-Chloropropane-1,2-diol, Molecular C3H7ClO2, Category: iodides-buliding-blocks.

Protein hydrolyzates produced by hydrochloric acid hydrolysis were analyzed for 3-chloropropane-1,2-diol and its enantiomers. It was found that (R)-3-chloropropane-1,2-diol and (S)-3-chloropropane-1,2-diol were present in the hydrolyzates in equimolar concentrations Model system experiments with glycerol, triolein and soy lecithin heated with hydrochloric acid in solution showed that these materials were precursors of 3-chloropropane-1,2-diol and yielded racemic mixtures of its enantiomers. Yields of 3-chloropropane-1,2-diols decreased in the order triolein > lecithin > glycerol. Mechanisms of 3-chloropropane-1,2-diol enantiomer formation during the production of protein hydrolyzates are presented and discussed as well as reaction pathways of their decomposition in alk. media via the corresponding (R)- and (S)-hydroxymethyloxiranes. In alk. media both 3-chloropropane-1,2-diol enantiomers decomposed at the same rate.
