The acid catalyzed oxidation of benzyl alcs. by N-chlorosaccharin was studied in aqueous AcOH medium in the presence of saccharin. The reaction is first-order with respect to [substrate] and [oxidant]. A plot of log k_obs vs. ρ is linear with σ = -3.07. The rate is not affected by added Cl^–. Bunnett’s plot shows that water mols. act as proton transfer agents in the rate determining step.

And the article was included in Materials Today Communications in 2022.COA of Formula: C9H3Cl3O3 This article mentions the following:

A nanofiltration membrane with a high affinity to water and high rejection of salts and hydrocarbons was developed by intercalating a supramol. compound, graphene oxide with β-cyclodextrin (GO-beta-CD), into its layer of separation The GO-beta-CD membranes were synthesized by interfacial polymerization of an aqueous solution of (GO-beta-CD)/piperazine with an organic solution of 1, 3, 5-benzenetricarbonyl trichloride on porous substrates of polysulfone (PSf). Fourier transform IR spectroscopy (FTIR), field-emission scanning electron microscope (SEM), energy dispersive x-ray(EDX), and at. force microscope (AFM) analyses were applied to confirm the successful incorporation of GO-beta-CD into the rejection layer of the synthesized membrane and analyze the morphol., surface characteristics, and structure of the membrane surface. The hydrophilicity and porosity of the GO-beta-CD-embedded membranes were greatly enhanced and were confirmed by the contact angle decline and permeability enhancement. The collective results and analyses showed that the permeability, salt rejection and oil separation were significantly enhanced by the addition of GO-beta-CD. The prepared membranes were featured with hydrocarbons separation efficiency of about 100%, divalent salt rejection of about 89% and monovalent salt rejection of about 74%. The fluxes of the produced membranes were 80% greater than NF bare membranes. Addnl., the GO-beta-CD membranes were stable under a long-trail filtration of 15 h and exhibited excellent mech. and performance stability.

And the article was included in Journal of Chemical Information and Modeling in 2006.SDS of cas: 2168-06-1 This article mentions the following:

The authors developed a new method to improve the accuracy of mol. interaction data using a mol. interaction matrix. This method was applied to enhance the database enrichment of in silico drug screening and in silico target protein screening using a protein-compound affinity matrix calculated by a protein-compound docking software. Our assumption was that the protein-compound binding free energy of a compound could be improved by a linear combination of its docking scores with many different proteins. The authors proposed two approaches to determine the coefficients of the linear combination. The first approach is based on similarity among the proteins, and the second is a machine-learning approach based on the known active compounds These methods were applied to in silico screening of the active compounds of several target proteins and in silico target protein screening.

Phosphoglycerate mutase 1 (PGAM1) coordinates glycolysis, pentose phosphate pathway, and serine synthesis to promote tumor growth through the regulation of its substrate 3-phosphoglycerate (3 PG) and product 2-phosphoglycerate (2 PG). Herein, based on our previously reported PGAM1 inhibitor PGMI-004A, we have developed anthraquinone derivatives as novel allosteric PGAM1 inhibitors and the structure-activity relationship (SAR) was investigated. In addition, we determined the co-crystal structure of PGAM1 and the inhibitor 8g, demonstrating that the inhibitor was located at a novel allosteric site. Among the derivatives, compound 8t was selected for further study, with IC₅₀ values of 0.25 and approx. 5 μM in enzymic and cell-based assays, resp. Mechanistically, compound 8t reduced the glycolysis and oxygen consumption rate in cancer cells, which led to decreased ATP (ATP) production and subsequent 5′ adenosine monophosphate-activated protein kinase (AMPK) activation. The inhibitor 8t also exhibited good efficacy in delaying tumor growth in H1299 xenograft model without obvious toxicity. Taken together, this proof-of-principle work further validates PGAM1 as a potential target for cancer therapy and provides useful information on anti-tumor drug discovery targeting PGAM1.

Sirtuins are protein deacylases regulating metabolism and stress responses, and are implicated in aging-related diseases. Small mol. activators for the human sirtuins Sirt1-7 are sought as chem. tools and potential therapeutics, such as for cancer. Activators are available for Sirt1 and exploit its unique N-terminus, whereas drug-like activators for Sirt2-7 are lacking. The authors synthesized and screened pyrrolo[1,2-a]quinoxaline derivatives, yielding the first synthetic Sirt6 activators. Biochem. assays show direct, substrate-independent compound binding to the Sirt6 catalytic core and potent activation of Sirt6-dependent deacetylation of peptide substrates and complete nucleosomes. Crystal structures of Sirt6/activator complexes reveal that the compounds bind to a Sirt6-specific acyl channel pocket and identify key interactions. The authors’ results establish potent Sirt6 activation with small mols. and provide a structural basis for further development of Sirt6 activators as tools and therapeutics.
