Abranches, Dinis O.; Soares, Bruna P.; Ferreira, Ana M.; Shimizu, Seishi; Pinho, Simao P.; Coutinho, Joao A. P. published an article in 2022, the title of the article was The impact of size and shape in the performance of hydrotropes: a case-study of alkanediols.Related Products of 111-29-5 And the article contains the following content:

Inspired by the recently proposed cooperative mechanism of hydrotropy, where water mols. mediate the aggregation of hydrotrope around the solute, this work studies the impact of apolar volume and polar group position on the performance of hydrotropes. To do so, the ability of two different families of alkanediols (1,2-alkanediols and 1,n-alkanediols) to increase the aqueous solubility of syringic acid is initially investigated. Interestingly, it is observed that in the dilute region (low hydrotrope concentration), the relative position of the hydroxyl groups of the alkanediols does not impact their performance. Instead, their ability to increase the solubility of syringic acid correlates remarkably well with the size of their alkyl chains. However, this is not the case for larger hydrotrope concentrations, where 1,2-alkanediols are found to perform, in general, better than 1,n-alkanediols. These seemingly contradictory findings are reconciled using theor. and exptl. techniques, namely the cooperative model of hydrotropy and chem. environment probes (Kamlet-Taft and pyrene polarity scales). It is found that the number of hydrotropes aggregated around a solute mol. does not increase linearly with the apolar volume of the former, reaching a maximum instead. This maximum is discussed in terms of competing solute-hydrotrope and hydrotrope-hydrotrope interactions. The results suggest that hydrotrope self-aggregation is more prevalent in 1,n-alkanediols, which neg. impacts their performance as hydrotropes. The results reported in this work support the cooperative model of hydrotropy and, from an application perspective, show that hydrotropes should be designed taking into consideration not only their apolar volume but also their ability to stabilize their self-aggregation in water, which neg. impacts their performance as solubility enhancers. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Related Products of 111-29-5

Hayashi, Mikihiro; Obara, Haruna; Miwa, Yohei published an article in 2021, the title of the article was Design and basic properties of polyester vitrimers combined with an ionomer concept.Reference of Pentane-1,5-diol And the article contains the following content:

Vitrimers are a novel class of crosslinked materials containing associative bond exchange properties. Here we demonstrate the preparation of vitrimers with ionic components to investigate the effects of ion-rich domain formation on vitrimer properties. An amorphous polyester that bears COOH side groups was synthesized, and some fraction of COOH was neutralized with Zn2+. The residual non-neutralized COOH was reacted with diepoxy crosslinkers, resulting in a network with ester bonds, OH groups, and COOH groups neutralized with Zn2+. The sample was further thermally annealed to induce aggregation of Zn2+ ionic groups. The aggregated Zn2+ groups in the network remained active for trans-esterification-based bond exchange, wherein the degree of ion aggregation can be a factor in tuning the bond-exchange properties. The present study provides some important knowledge on the design of new mol. systems of vitrimers with tunable bond exchange properties.

And the article contained the following:

By screening directed libraries of serine hydrolase inhibitors using the cell surface form of endothelial lipase (EL), the authors identified a series of carbamate-derived (EL) inhibitors. Compound (I) raised plasma HDL-C levels in the mouse, and a correlation was found between HDL-C and plasma compound levels. Spectroscopic and kinetic studies support a covalent mechanism of inhibition. The authors’ findings represent the first report of EL inhibition as an effective means for increasing HDL-C in an in vivo model.

Salerno, Anna; Fragasso, Gabriele; Montanaro, Claudia; Cera, Michela; Torlasco, Camilla; Maranta, Francesco; Margonato, Alberto published an article in 2010, the title of the article was Role of metabolic modulation in the management of chronic ischemic heart disease.SDS of cas: 32462-30-9 And the article contains the following content:

Abstract: Coronary artery disease (CAD) is a major cause of morbidity and mortality in the world. Therapy for stable CAD is currently based on conventional medical therapy, including nitrates, β-blockers and calcium-channels antagonists and, more recently, metabolic therapy, of which a pivotal therapeutic role is increasingly recognized. Under normoxic condition, the healthy heart derives 2/3 of its energy from the free fatty acid (FFA) pathway, the other source of energy being derived from glucose oxidation However, glycolysis requires less O2 per mol of ATP generated compared with FFA oxidation On this basis, shifting energy substrate utilization from fatty acid metabolism to glucose metabolism can be more efficient in terms of ATP production per mol of oxygen utilized. A number of different approaches have been used to manipulate energy metabolism in the heart. These approaches include direct agents, such as dichloroacetate, -carnitine, ribose or lipoic acid which directly increase glucose oxidation, or indirect methods, through the inhibition of free fatty acids oxidation Among these, the most important are carnitil-palmitoyl-transpherase I (CPT-I) inhibitors, which inhibit FFA mitochondrial uptake (e.g. etomoxir, perhexiline, oxphenicine), or 3-ketoacyl-coenzyme-A thiolase (3-KAT) inhibitors, such as trimetazidine, which inhibits the last enzyme involved in β-oxidation In most patients with ischemic heart disease metabolic abnormalities, if not adequately treated, will heavily contribute to the occurrence of complications, of whom severe left ventricular dysfunction is at present one of the most frequent and insidious. In this paper, all possible metabolic approaches to ischemic heart disease are reviewed and discussed. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).SDS of cas: 32462-30-9

Huangfu, Xinlei; Wang, Yueqiao; Lu, Guozhang; Cao, Yinwei; Tang, Guo; Zhao, Yufen published an article in 2020, the title of the article was Direct synthesis of phosphorotrithioites and phosphorotrithioates from white phosphorus and thiols.Synthetic Route of 143-10-2 And the article contains the following content:

White phosphorus (P4) is still the major com. P-atom source for the production of organophosphorus compounds Conventionally, C-S-P bonds were constructed from environmentally questionable P(O)X directly or indirectly. From the green chem. point of view, formation of C-S-P bonds from inorganic mol. P4 in an easy-to-operate and atom-economical way is essential because it will avoid the hazardous chlorination process. Only five methods for the formation of C-S-P bonds from P4 have been developed over the past 70 years. Here, the first general and high-yielding synthesis of P(SR)3 and P(O)(SR)3 involving P4 and thiols is presented. With the use of KOH or K2CO3 as a base and DMSO-toluene as a solvent, both arythiols and alkylthiols are tolerant in this transformation. The reaction is characterized by a complete conversion of white phosphorus. This operationally simple and environmentally sound reaction shows a broad scope of substrates and good functional group tolerance. Moreover, this method can be easily adapted to large-scale preparation The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Synthetic Route of 143-10-2

On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:

The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2
