crystal structure of a cationic bile salt Derivative 3β 5β 7α 12α 3 2 naphthyloylamino 7 12 dihydroxycholan 24 triethylAmmonium iodide
Crystals, 2019Co-Authors: Francisco Meijide, Julio A. Seijas, Santiago De Frutos, Victor H. H. Soto, M Vazqueztato, Juan Ventura Trillo Novo, José Vázquez TatoAbstract:The crystal structure of the iodide salt of a Quaternary Ammonium Derivative of cholic acid having a naphthalene group attached to the 3rd position of the steroid nucleus through an amide bond ([3β,5β,7α,12α]-3-(2-naphthyloylamino)-7,12-dihydroxycholan-24-triethylAmmonium iodide) has been resolved. The compound crystallizes in the P212121 orthorhombic space group (a/A = 10.9458(3); b/A = 12.1625(3); c/A = 28.4706(7)). The lateral chain adopts a fully extended tttt conformation because the Quaternary Ammonium group cannot participate in the formation of hydrogen bonds. The iodide ion is involved in the formation of hydrogen bonds as well as the amide group and the two steroid hydroxy groups. Hirshfeld surface analysis confirms that these contacts, as well as the electrostatic interactions, stabilize the structure. The helixes around the 21 screw axis are right-handed ones.

synthesis and moisture absorption and retention activities of a carboxymethyl and a Quaternary Ammonium Derivative of α α trehalose
Carbohydrate Research, 2010Co-Authors: Shaoli Yang, Zhanyong Guo, Yuling Zhou, Lili Zhou, Qinzhao Xue, Fengping Miao, Song QinAbstract:Carboxymethyl alpha,alpha-trehalose (CMT) and a Quaternary Ammonium Derivative of alpha,alpha-trehalose (QT) were successfully prepared, and their moisture absorption and retention activities were assessed. Results showed that both CMT and QT had better moisture absorption abilities at 43% and 81% relative humidity (RH) than alpha,alpha-trehalose. In addition, the two alpha,alpha-trehalose Derivatives had better moisture retention abilities than alpha,alpha-trehalose under three humidity conditions: 81% RH, 43% RH, and under dry conditions. Therefore, carboxymethylation and quaternarization could improve the moisture absorption and retention abilities of alpha,alpha-trehalose. CMT and QT showed better moisture absorption ability and moisture retention ability than that of hyaluronan (HA), and could potentially find a use as moisture retention ingredient, for example, in cosmetics.
