Also calculate the samples enantiomeric excess. Insoluble in water. 3) Recovery of resolved acid: Add all of the solid to 8 mL of ice-cold 6 M HCl in a small beaker or glass tube, place the sample in an ice bath. InChI=1S/C10H10O4/c11-9(12)6-8(10(13)14)7-4-2-1-3-5-7/h1-5,8H,6H2,(H,11,12)(H,13,14)/t8-/m0/s1, CSID:643286, http://www.chemspider.com/Chemical-Structure.643286.html (accessed 08:22, Mar 4, 2023), Validated by Experts, Validated by Users, Non-Validated, Removed by Users, Predicted data is generated using the ACD/Labs Percepta Platform - PhysChem Module, Predicted data is generated using the US Environmental Protection Agencys EPISuite, Click to predict properties on the Chemicalize site, For medical information relating to Covid-19, please consult the. Determine the mass of purified crystals and prepare a solution to analyze by polarimetry, first measure about 0.4g of your (S)-phenylsuccinic acid and then dissolve in exactly 10mL of HPLC-grade acetone. Multiple studies have demonstrated succinate-induced aggregation, but the effect has high inter-individual variability. [26] As such, succinate links TCA cycle dysfunction or metabolic changes to cell-cell communication and to oxidative stress-related responses. Through these mechanisms, succinate accumulation has been shown to regulate production of inflammatory cytokines. OPTICAL RESOLUTION OF 2-PHENYLSUCCINIC ACID (From R. Stephani and V. Cesare, Journal of Chemical Education 74, 1226, 1997) 1) Background: The purposes of this experiment are to show how enantiomers can be separated if they are converted into a mixture of diastereomers and to understand how careful choice of solvent can permit selective precipitation of one compound from a mixture of compounds. 100mL round bottom flask. where the more soluble compound Copyright 2007-2023 Santa Cruz Biotechnology Inc. All Rights Reserved. First, we exploit its chemical nature it is m acid) by treating it with an optically active biologically produced base, L-proline. The phenylsuccinic acid acts as the proton donor, while proline is the proton acceptor OH Ph OH OH Ph protoner) acid-base reaction OH SINH phreyhuccinic acid L-prolier (base) equimolarite of R+5) (5) PLUS The two salts shown above are stereoisomers that are not mirror images, so are a pair of diastereomers. 8, 4533 (2008).

The enantiomeric excess was 35.5% which is the measurement of purity. In this experiment, a reflux reaction is conducted between the pheny-succinic acid and proline to produce salt. [5], Historically, succinic acid was obtained from amber by distillation and has thus been known as spirit of amber. Soc. Google Scholar. Molecular Formula: C 10 H 10 O 4. Mass of product dissolved in acetone: 0 Solubility: Not available. [7] The mechanism by which succinate accumulates in immune cells is not fully understood. [5], As a radical group it is called a succinyl (/sksnl/) group. One proline has a position available for one extra proton, so the two protons end up on two different prolines. Exact concentration: 0 10 mL=0. May cause respiratory tract irritation. 2) Pre-Lab Report: EXPERIMENTAL SECTION 1) Synthesis of diastereomeric salts: Weigh racemic phenylsuccinic acid (0,5g, 2.57 mmole) and L-prolinc (0.3 g. 2.61 mmole) into a 100 ml boiling flask, and swirl to dissolve the solid. The enantiomeric excess (ee) can be calculated with the expression above, where []mixture and []pureenantiomer are the specific rotations of th. [19] Succinic acid is used primarily as an acidity regulator[20] in the food and beverage industry. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. (R)-(-)-Phenylsuccinic acid | C10H10O4 | CID 736145 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological . too much present in sample (soluble) Think of a chiral center as an atom to which four different, groups are covalently attached. The calculated specific rotation came out to be 60.65, meaning that it was not optimally pure but the fact that it was positive meaning that it was more of an S enan-tiomer than an R which was preferred. If you study models of chiral molecules, it soon becomes apparent that their mirror images are not superposable on each other. Inhalation: 7, 880 (2005). In this experiment, 2-propanol is the suitable solvent that will selectively precipitate most of one diastercomer and leave most of the other diastercomer in the solution. Molecular Formula: C 10 H 10 O 4. Oversuccination occurs when more than one succinate adds to a substrate. The chiral recognition abilities of . phenylsuccinic acid (H 2A) as the model enantiomers. Molecular Formula:C10H10O4 Molecular Weight:194.19 Section 10 - Stability and Reactivity HIF1 is known to induce transcription of more than 60 genes, including genes involved in vascularization and angiogenesis, energy metabolism, cell survival, and tumor invasion. 2) Calculate the enantiomeric excess if the specific rotation obtained after recrystallization is 103.2. (If there is no precipitate, use a Pasteur pipet to remove about I mL to a small test tube. Japan (1987), 60, 824-827). A key candidate transporter is INDY (I'm not dead yet), a sodium-independent anion exchanger, which moves both dicarboxylate and citrate into the bloodstream. cally, the less soluble diastere- [32] The ligand specificity of GPR91 was rigorously tested using 800 pharmacologically active compounds and 200 carboxylic acid and succinate-like compounds, all of which demonstrated significantly lower binding affinity. [30] In general, leakage from the mitochondria requires succinate overproduction or underconsumption and occurs due to reduced, reverse or completely absent activity of SDH or alternative changes in metabolic state. ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agencys EPISuite, Compounds with the same molecular formula, Search Google for structures with same skeleton, CAUTION: May irritate eyes, skin, and respiratory tract. Succinate thus serves as a direct electron donor to the electron transport chain, and itself is converted into fumarate. solid. In order to recrystallize the. C. B. Aakery and D. J. Salmon, CrystEngComm 7, 439 (2005). Percent recovery: 00 100 =4% 1035, 203 (2013). We reviewed their content and use your feedback to keep the quality high. The phenylsuccinic acid is a proton donor making proline the proton acceptor. Question: In this experiment, racemic (RS)-phenylsuccinic acid is separated (resolved) into optically active cautiouets in a sequence of two steps. The chiral recognition abilities of the two selectors are opposite . CAS Number: 635-51-8. comes insoluble in water. The site owner may have set restrictions that prevent you from accessing the site. [citation needed], Succinate is one of three oncometabolites, metabolic intermediates whose accumulation causes metabolic and non-metabolic dysregulation implicated in tumorigenesis. Stir the mixture with a glass rod for 5 minutes. A suitable solvent is found by trial and error. [30] Transport across the plasma membrane is likely tissue specific. For this reason, if the biologically produced product contains one or more chiral centers, it is optically active Examples include table sugar, honey, monosodium glutamate (MSG), vitamins, paper (if we could measure it! May cause eye irritation. The toxicological properties To purify, recrystallize the (S)-phenylsuccinic acid precipitate from water. The first source was natural products chemicals produced by living organisms. In the retina, succinate accumulates in retinal ganglion cells in response to ischemic conditions. The solid that results is now-resolved phenylsuccinic acid in its protonated form. succinic acid and proline to pro- [citation needed], As a food additive and dietary supplement, succinic acid is generally recognized as safe by the U.S. Food and Drug Administration. [40] In spite of a general downregulation of the TCA cycle under these conditions, succinate concentration is increased. 4 0 obj This shows the degree to which a sample contains one enantiomer in greater amounts than the other. This diethyl ester is a substrate in the Stobbe condensation.

Add a magnetic stir bar and gently mix the contents of the flask until you achieve a Keep adding hot water until the solid fully dissolves. This involves an acid-base reaction with (s)-proline and restoring the enantiomer by neutralizing the salt created to find the optical purity by measuring the optical rotation using polarimetry. [35] First, 2-oxoglutarate coordinates with an Fe(II) ion bound to a conserved 2-histidinyl1-aspartyl/glutamyl triad of residues present in the enzymatic center. Part of Springer Nature.

Allow to fully dry & poor the filtrate into the aqueous hazardous waste container. [36][37], Succinate inhibition of prolyl hydroxylases (PHDs) stabilizes the transcription factor hypoxia inducible factor (HIF)1. Once the water is boiling, add hot water to the 125mL flask with the solid. Accumulation of either fumarate or succinate reduces the activity of 2-oxoglutarate-dependent dioxygenases, including histone and DNA demethylases, prolyl hydroxylases and collagen prolyl-4-hydroxylases, through competitive inhibition. Proline likewise gains 18+, but this gives ita net + charge, making it very soluble in water. This is simple since neutral phenylsuccinic acid is poorly soluble in water. F. Toda, K. Tanaka, A.
