| | 3,3`-Dithiobispropanoic acid bis(N-hydroxysucciniMde ester) Usage And Synthesis |
| Description | DSP Crosslinker is a cleavable crosslinker. It contains two terminal NHS ester moieties which can react with primary amines. The disulfide bonds can be cleaved via a reduction reaction using Dithiothreitol (DTT) reagent. | | Chemical Properties | Off-White Solid | | Uses | 3,3`-Dithiobispropanoic acid bis(N-hydroxysucciniMde ester) can be used as amine reactive homobifunctional cross-linking reagent, cleavable under mild conditions with hydroxylamine (pH 8.5, 3-6 h, 37oC) | | Uses | 3,3`-Dithiobispropanoic acid bis(N-hydroxysucciniMde ester) can be used in the crosslinking of intracellular proteins prior to cell lysis. | | Uses | 3,3′-Dithiodipropionic acid di(N-hydroxysuccinimide ester) (DSP) has been used as a protein cross-linker. | | General Description | 3,3′-Dithiodipropionic acid di(N-hydroxysuccinimide ester) (DSP) is a homobifunctional cross-linking reagent containing a cleavable disulfide linkage. It is typically coupled to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5). | | reaction suitability | reagent type: cross-linking reagent | | Synthesis | General procedure for the synthesis of bis(N-hydroxysuccinimide ester) 3,3'-dithiobispropionic acid from 3,3'-dithiobispropionic acid and N-hydroxysuccinimide: To a solution of dichloromethane (20 mL) containing 3,3'-dithiobispropionic acid (1 g, 4.75 mmol) was added sequentially 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride ( WSC) (2.16 g, 10.5 mmol) and N-hydroxysuccinimide (1.21 g, 10.5 mmol). The reaction mixture was stirred at room temperature for 2 hours. Upon completion of the reaction, the solution was concentrated by vacuum to remove the solvent and the obtained residue was purified by silica column chromatography (eluent ratio ethyl acetate/hexane = 1:5) to give the final target product 3,3'-dithiodipropionic acid bis(N-hydroxybutanediimide ester) (1.63 g, 85% yield). The structure of the product was confirmed by 1H NMR (DMSO-d6, 400 MHz) and FAB mass spectrometry: 1H NMR δ 3.16 (m, 8H), 2.82 (s, 8H); FAB mass spectrometry (DMSO-d6) [(M+H)+] calculated value of 405, measured value 405. | | References | [1] Bioorganic and Medicinal Chemistry, 2012, vol. 20, # 1, p. 96 - 100
