Chromatog. NMR spectroscopy can seperate the mixtures of species with significantly different mol. size, but generally fails for isomeric species. Herein, we reported the resolution of trans- and cis-isomers and their structural analog, which are different in mol. shapes, but similar in mass, were greatly enhanced in the presence of silica soluble The mixtures of maleic acid, fumaric acid and succinic acid, and the mixtures of trans- and cis-1,2-cyclohexanedicarboxylic acids, were distinguished by virtue of their different degrees of interaction with silica soluble Moreover, we found mixed solvents could improve the spectral resolution of DOSY spectra of mixtures

Application In Synthesis of cis-Cyclohexane-1,2-dicarboxylic acid. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: cis-Cyclohexane-1,2-dicarboxylic acid, is researched, Molecular C8H12O4, CAS is 610-09-3, about Organic ligand binding by a hydrophobic cavity in a designed tetrameric coiled-coil protein. Author is Mizuno, Toshihisa; Hasegawa, Chinatsu; Tanabe, Yoichi; Hamajima, Kenta; Muto, Takashi; Nishi, Yoshinori; Oda, Masayuki; Kobayashi, Yuji; Tanaka, Toshiki.

The design and characterization of a hydrophobic cavity in de novo designed proteins provides a wide range of information about the functions of de novo proteins. We designed a de novo tetrameric coiled-coil protein with a hydrophobic pocketlike cavity. Tetrameric coiled coils with hydrophobic cavities have previously been reported. By replacing one Leu residue at the a position with Ala, hydrophobic cavities that did not flatten out due to loose peptide chains were reliably created. To perform a detailed examination of the ligand-binding characteristics of the cavities, we originally designed two other coiled-coil proteins: AM2, with eight Ala substitutions at the adjacent a and d positions at the center of a bundled structure, and AM2W, with one Trp and seven Ala substitutions at the same positions. To increase the association of the helical peptides, each helical peptide was connected with flexible linkers, which resulted in a single peptide chain. These proteins exhibited CD spectra corresponding to superhelical structures, despite weakened hydrophobic packing. AM2W exhibited binding affinity for size-complementary organic compounds The dissociation constants, Kd, of AM2W were 220 nM for adamantane, 81 μM for 1-adamantanol, and 294 μM for 1-adamantane acetic acid, as measured by fluorescence titration analyses. Although it was contrary to expectations, AM2 did not exhibit any binding affinity, probably due to structural defects around the designed hydrophobic cavity. Interestingly, AM2W exhibited incremental structure stability through ligand binding. Plugging of structural defects with organic ligands would be expected to facilitate protein folding.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Hunsdiecker reaction of silver salts of cis- and trans-1,2-cyclohexanedicarboxylic acid》. Authors are Abell, Paul I..The article about the compound:cis-Cyclohexane-1,2-dicarboxylic acidcas:610-09-3,SMILESS:O=C([C@H]1[C@@H](C(O)=O)CCCC1)O).Application of 610-09-3.

Decarboxylation of the Ag salts of cis- and trans-1,2-cyclohexanedicarboxylic acids (I, Ia) by the action of halogen according to Hunsdiecker, et al. (C.A. 38, 374), gave only trans-1,2-dibromocyclohexane (IIa) through isomerization which appeared to take place at an intermediate stage in the reaction. Com. cis-1,2-cyclohexanedicarboxylic anhydride hydrolyzed in boiling H2O gave I, m. 191-4°, isomerized by heating 8 hrs. at 170-80° with a small amount of dilute HCl in a sealed tube to yield 61.5% Ia, m. 228.5-30.5° (from EtOH). Carefully neutralized solutions of the Na salts of I and Ia treated with an exactly equivalent quantity of aqueous AgNO3 and filtered, the precipitate carefully washed with H2O, alc., and Et2O, dried several days over P2O5 in vacuo, and screened to 100 mesh gave Ag salts (III, IIIa) suitable for reaction with Br. Reaction of III and IIIa with Br was carried out at various temperatures by the inverse addition procedure of Conly (C.A. 48, 2561b) in which the dry III or IIIa was added to Br in CCl4, in an apparatus in which the speed and extent of the reaction were followed by observation of the CO2 evolved. The products of the reaction were tabulated (Ag salt, temperature of reaction, % yield, m.p. IIa, n25D, and structure as shown by infrared spectrum given): III, 0-25°, 43, -4.8°, 1.5503, all trans; III, reflux, 47, -4.7°, 1.5505, all trans; IIIa, 0-25°, 48, -4.5°, 1.5507, all trans; IIIa, reflux, 37, -2.5°, 1.5510, all trans. To establish the stability to isomerization under the above exptl. conditions, known cis-1,2-dibromocyclohexane (II) and IIa were refluxed 12 hrs. with Br and AgBr. II, m. 10.0°, n25D 1.5512, was recovered with a 60% yield of material, m. 6.5°, n25D 1.5511, all cis; and IIa, m. -4.5°, n25D 1.5505, similarly yielded 94% material, m. -4.5°, n25D 1.5505, all trans. Although the data did not distinguish partial isomerization from complete retention of configuration a very large proportion of II survived the reaction. No isomerization of II took place on 12 hrs. refluxing with Br and AgBr in anhydrous CCl4. The mechanistic implications were discussed briefly.

The maleic, oxalic and citric acids showed infinitely large kH values indicating very strong interactions with D-cellobiose. The next highest interactions were found with phthalic acid (kH = 248.8 Hz).
