Purpose: 4,4-Bipyridine and 1,2-bis(4-pyridyl)ethane were combined with achiral, racemic mixture or pure enantiomers of selected carboxylic acids with similar constituents (p-toluic acid, rac-2-phenylbutyric acid, racemic or S-phenylsuccinic acid). Succinate exits the mitochondrial matrix and passes through the inner mitochondrial membrane via dicarboxylate transporters, primarily SLC25A10, a succinate-fumarate/malate transporter. 2) Calculate the enantiomeric excess if the specific rotation obtained after recrystallization is 103.2. [31] SDH mutations have also been identified in gastrointestinal stromal tumors, renal tumors, thyroid tumors, testicular seminomas and neuroblastomas. This is an ordinary acid-base reaction that produces a salt. is conducted between the pheny- Swirl and pour as fast as possible into a clean Buchner funnel. this experiment, a reflux reaction The solid that results is now-resolved phenylsuccinic acid in its protonated form. May cause eye irritation. Most often, these pieces can attach to the enzyme only in one particular, orientation. Copyright 2007-2023 Santa Cruz Biotechnology Inc. All Rights Reserved. [29] As of 2016 the inhibition of succinate-mediated ROS production was under investigation as a therapeutic drug target.[29]. out to be a good recrystallization solvent for this product. Chirality is a necessary condition for the existence of optical activity (the ability to cause rotation of the plane of polarized light). [11], Genetically engineered Escherichia coli and Saccharomyces cerevisiae are proposed for the commercial production via fermentation of glucose. a mixture of both enantiomers Show transcribed image text. Measure the specific rotation and determine the enantiomeric excess of the sample. It now must be recovered from the salt (the second step).

[36] Additionally, succinate-promoted activation of HIF-1 generates a pseudo-hypoxic state that can promote tumorneogensis by transcriptional activation of genes involved in proliferation, metabolism and angiogenesis. Growth Des. Both anions are colorless and can be isolated as the salts, e.g., Na(CH2)2(CO2H)(CO2) and Na2(CH2)2(CO2)2. [26] As such, succinate links TCA cycle dysfunction or metabolic changes to cell-cell communication and to oxidative stress-related responses. Keep adding hot water until the solid fully dissolves. Any rotational effect that one enantiomer has on plane-polarized light will be exactly canceled somewhere else in the mixture by its mirror image. L. Fbin, Cryst. ()-phenylsuccinic acid N CO 2H H H (-)-Proline Week 1: Resolution of ()-phenylsuccinic acid Procedure In a clean, dry, 250 mL round-bottomed flask, dissolve 2.9 g of ()-phenylsuccinic acid in 75 mL of 2-propanol. The solid was recrystallized and the final solid is filtered out. ABC corresponds to the atomic number of the most characteristic element or the most characteristic organic group in the molecule. To purify, recrystallize the (S)-phenylsuccinic acid precipitate from wa- behave identically toward physical tests like melting and boiling points and solubility in given solvents. CAS Number: 4036-30-. Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space, changing gene expression patterns, modulating epigenetic landscape or demonstrating hormone-like signaling. Diastecomers are not chemically identical, and so they differ in common physical properties. S. Mittapalli, M. K. C. Mannava, U. [15], Succinic acid is a precursor to some polyesters and a component of some alkyd resins. Note that the two diastercomeric salts (S.S) and (R.S) differ in their mions (phenylsuccinate), which are nonsuper-posable mirror images, but have identical cations (L-proline).

[25], Accumulation of fumarate can drive the reverse activity of SDH, thus enhancing succinate generation. So, for optical activity to be evident, there must be an excess of one enantiomer over its mirror image. [12], In 2004, succinate was placed on the US Department of Energy's list of top 12 platform chemicals from biomass. Share Improve this answer Follow edited Oct 28, 2019 at 15:24 This property is a direct consequence of the configuration, or orientation of, bonded atoms in space, around the chiral center. J. M. Chen, Z. Under anaerobic conditions certain bacteria such as A. succinogenes, A. succiniciproducens and M. succiniciproducens, run the TCA cycle in reverse and convert glucose to succinate through the intermediates of oxaloacetate, malate and fumarate. Succinate is also produced from butane via maleic anhydride. Once the water is boiling, add hot water to the 125mL flask with the solid. Stir the mixture with a glass rod for 5 minutes. Moreover, the cold water wash and filtration performed was able to recover the crude solid. ter. Use a Pasteur pipet to drizzle 1-2 mL of ice-cold water over the entire surface of the solid to wash away as much 6 M HCl as possible. The phenylsuccinic acid Give the % of each enantiomer. Typi- cally, the less soluble diastere- omeric salt was isolated, the enantiomer of phenylsuccinic acid remains. May cause eye, skin, and respiratory [30][32], Extracellular succinate regulates cardiomyocyte viability through GPR91 activation; long-term succinate exposure leads to pathological cardiomyocyte hypertrophy.

Heat and gently swirl the mixture on the hot plate until all the solid dissolves (add a little more water if the entire solid is not in solution just as the solution begins to gently boil). Shop DL-Phenylsuccinic acid, 98+%, Thermo Scientific Chemicals at Fishersci.com This process Question: In this experiment, racemic (RS)-phenylsuccinic acid is separated (resolved) into optically active cautiouets in a sequence of two steps. N. Shan, A. D. Bond, and W. Jones, Cryst. [32] Overall, the EC50 for succinate-GPR91 is in the 2050 uM range. [40] In spite of a general downregulation of the TCA cycle under these conditions, succinate concentration is increased. This shows the degree to which a sample contains one enantiomer in greater amounts than the other. Sorry, it seems JavaScript is not enabled in your browser. Lowell, Massachusetts.

Subsequently, the primary substrate enters the binding pocket and lastly dioxygen binds to the enzyme-substrate complex. To get rid of 2-propanol and any unreacted phenylsuccinic acid, wash the crystals with 10 mL of acetone. Transamination and subsequent decarboxylation of alpha-ketoglutarate leads to the formation of GABA.

This work presents more extensive results of separation of phenylsuccinic acid enantiomers by biphasic recognition chiral extraction (BRCE), which is an important intermediate of N-methyl--phensuximide and antitumor agents (in Fig. Molecular Weight: 194.18. One proline has a position available for one extra proton, so the two protons end up on two different prolines. [7] For dendritic cells, succinate functions as a chemoattractant and increases their antigen-presenting function via receptor stimulated cytokine production. [32] In inflammatory macrophages, succinate-induced stability of HIF1 results in increased transcription of HIF1-dependent genes, including the pro-inflammatory cytokine interleukin-1. This specificity of attachment means that the atoms of the product always end up being connected to each other in only one of several possible ways. comes insoluble in water.

[6][22]:Section 17.1 All metabolic pathways that are interlinked with the TCA cycle, including the metabolism of carbohydrates, amino acids, fatty acids, cholesterol, and heme, rely on the temporary formation of succinate. Curr. 7, 4 (2007). Succinic acid is a white, odorless solid with a highly acidic taste. In the retina, succinate accumulates in retinal ganglion cells in response to ischemic conditions. configuration enantiomer, the other diastereomer must be more soluble during the filtration In order to recrystallize the solid, boiling water was added to the solid until it fully dissolves to achieve a complete homoge-nous mixture. It washes away in the acidic water, leaving nearly pure phenylsuccinic acid as the solid.) properties of this substance have not been fully investigated. The phenylsuccinic acid gave up two positives, so it is a dianion. [28], The activity of succinate dehydrogenase (SDH), which interconverts succinate into fumarate participates in mitochondrial reactive oxygen species (ROS) production by directing electron flow in the electron transport chain. Article These chemicals are invariably synthesized by catalysts called I enzymes, which are large chiral molecules specially designed to carry out a particular chemical transformation. Single crystal structures, thermal analysis, powder X-ray analysis and equilibrium solubility in water and ethanol of the cocrystals were measured. By signing up, you indicate that you have read and agree to the terms in our privacy policy. 4, 339 (2007). Chem. The phenylsuccinic acid would bind to the proton (H+), where it loses its negative charge and becomes insoluble in water. In the liver, succinate serves as a paracrine signal, released by anoxic hepatocytes, and targets stellate cells via GPR91. How does one obtain optically active compounds? [41], Succinate accumulation under hypoxic conditions has been implicated in the reperfusion injury through increased ROS production. Insoluble in water. The chiral recognition abilities of . [35] Succinate may interfere with the enzymatic process by attaching to the Fe(II) center first, prohibiting the binding of 2-oxoglutarate. [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. Let Cool for 15 min: very chunky, wet-sand-like consistency, almost solid - slushy, stacking interaction leads to the formation of 3D supramolecular structure. Optically active reagents have long been important in studies of reaction mechanisms because they may offer glimpses at the molecular details of the process as the reaction proceeds. To purify, recrystallize the (S)-phenylsuccinic acid precipitate from water. 4, 310 (2007). Growth Des. [30] Transport across the plasma membrane is likely tissue specific. Organic Chemistry I As a consequence, the mixture cases no net rotation, and appears optically inactive. Add L-proline (1.15 g 0.01 mole). The resulting solid acid can be recovered by filtration. [19] Succinic acid is used primarily as an acidity regulator[20] in the food and beverage industry. sion of an enantiomer to a di- <> [12][13], Succinic acid can be dehydrogenated to fumaric acid or be converted to diesters, such as diethylsuccinate (CH2CO2CH2CH3)2. 7, 880 (2005). 4, 279 (1987).
