Lynn published the artcile< Abiotic Reduction Reactions of Dichloroacetamide Safeners: Transformations of ""Inert"" Agrochemical Constituents>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is abiotic reduction reaction modeling dichloroacetamide safener transformation.

Safeners are so-called “”inert”” constituents of herbicide formulations added to protect crops from the toxic effects of herbicides. We examined the reactivity of three dichloroacetamide safeners and 12 structural analogs [all neutral compounds of the form Cl2CXC(=O)NRR’; X = H, Cl; R-groups include alkyl, branched alkyl, n-allyl, and cyclic moieties] in one homogeneous and two heterogeneous reductant systems: solutions of Cr(H2O)62+, suspensions of FeII-amended goethite, and suspensions of FeII-amended hematite. Analyses of reaction products indicate each safener can undergo stepwise hydrogenolysis (replacement of chlorine by hydrogen) in each system at near-neutral pH. The first hydrogenolysis step generates compounds similar (in one case, identical) to herbicide active ingredients. Rates of product formation and (when reactions were sufficiently fast) parent loss were quantified; reaction rates in heterogeneous systems spanned 2 orders of magnitude and were strongly influenced by R-group structure. The length of n-alkyl R-groups exerted opposite effects on hydrogenolysis rates in homogeneous vs. heterogeneous systems: as R-group size increased, reduction rates in heterogeneous systems increased, whereas reduction rates in the homogeneous system decreased. Branched alkyl R-groups decreased hydrogenolysis rates relative to their straight-chain homologs in both homogeneous and heterogeneous systems. Reaction rates in heterogeneous systems can be described via polyparameter linear free energy relationships employing mol. parameters likely to influence dichloroacetamide adsorption. The propensity of dichloroacetamide safeners to undergo reductive transformations into herbicide-like products challenges their classification as “”inert”” agrochem. ingredients.

Ahmad, Tanveer; Mehmood, Tariq; Shahid, Muhammad; Ahmad, Adnan; Basra, Muhammad Asim Raza; Zia-ur-Rehman, Muhammad; Munawar, Munawar Ali published the artcile< In vivo anti-diabetic studies of sulfonylurea-sulfonamide hybrids>, HPLC of Formula: 94-20-2, the main research area is antidiabetic sulfonylurea sulfonamide hybrid.

Owing to alarming increase of diabetes mellitus around the world, there is a need to discover new mols. to tackle with the problem. In this work, sulfonamides and sulfonylurea-sulfonamide hybrids were synthesized from simple mol. of 4-aminobenzenesulfonamide by its reaction with aryl sulfonyl chlorides. Anti-diabetic activities of these pharmacophores were studied by oral glucose tolerance test (OGTT) percentage anal. on Sprague Dawley (SD) rats at the dose of 20mg/kg using glibenclamide (GC). Among these synthesized pharmacophores, six compounds exhibited percentage reduction (20.47 ± 2.54 to 44.97 ± 2.16%) and (20.79 ± 1.55 to 37 ± 2.94%) in blood glucose level at 20mg/kg dose compared to glibenclamide (74 ± 3.10% reduction) 50mg/kg dose of glibenclamide after 2 and 5 h of oral administration resp. Present results showed that these compounds might be excellent addition in the drugs used to suppress the higher level of blood glucose level in diabetes mellitus.

Mao, Zhifan; Liu, Wenwen; Huang, Yunyuan; Sun, Tianyue; Bao, Keting; Feng, Jiali; Moskalev, Alexey; Hu, Zelan; Li, Jian published the artcile< Anti-aging effects of chlorpropamide depend on mitochondrial complex-II and the production of mitochondrial reactive oxygen species>, SDS of cas: 94-20-2, the main research area is chlorpropamide antiaging agent mitochondrial complex2 aging; ATP sensitive potassium channels; Anti-aging; Chlorpropamide; Mitochondrial complex II; Mitochondrial reactive oxygen species; Senescence; Succinate dehydrogenase; Sulfonylureas.

Sulfonylureas are widely used oral anti-diabetic drugs. However, its long-term usage effects on patients lifespan remain controversial, with no reports of influence on animal longevity. Hence, the anti-aging effects of chlorpropamide along with glimepiride, glibenclamide, and tolbutamide were studied with special emphasis on the interaction of chlorpropamide with mitochondrial ATP-sensitive K+ (mitoK-ATP) channels and mitochondrial complex II. Chlorpropamide delayed aging in Caenorhabditis elegans, human lung fibroblast MRC-5 cells and reduced doxorubicin-induced senescence in both MRC-5 cells and mice. In addition, the mitochondrial membrane potential and ATP levels were significantly increased in chlorpropamide-treated worms, which is consistent with the function of its reported targets, mitoK-ATP channels. Increased levels of mitochondrial reactive oxygen species (mtROS) were observed in chlorpropamide-treated worms. Moreover, the lifespan extension by chlorpropamide required complex II and increased mtROS levels, indicating that chlorpropamide acts on complex II directly or indirectly via mitoK-ATP to increase the production of mtROS as a pro-longevity signal. This study provides mechanistic insight into the anti-aging effects of sulfonylureas in C. elegans.

In this sustainable protocol, 2-aminobenzonitriles were directly transformed to quinazolinones using alc.-water system. A variety of quinazolinones was successfully synthesized in good to excellent yields by utilizing challenging methanol and aliphatic alcs. The practical applicability of the protocol was extended by preparative scale synthesis of various heterocycles as well as natural products. To understand the mechanism of this protocol, several control experiments and DFT studies were carried out. Based on the DFT calculations, a metal-ligand cooperative mechanism was proposed for this system.

Baranauskiene, Lina; Skiudaite, Lina; Michailoviene, Vilma; Petrauskas, Vytautas; Matulis, Daumantas published the artcile< Thiazide and other Cl-benzenesulfonamide-bearing clinical drug affinities for human carbonic anhydrases>, Safety of o-Chlorobenzenesulfonamide, the main research area is human carbonic anhydrase chlorine benzenesulfonamide thiazide drug affinity.

Twelve carbonic anhydrase (CA) isoforms catalyze carbon dioxide hydration to bicarbonate and acid protons and are responsible for many biol. functions in human body. Despite their vital functions, they are also responsible for, or implicated in, numerous ailments and diseases such as glaucoma, high altitude sickness, and cancer. Because CA isoforms are highly homologous, clin. drugs designed to inhibit enzymic activity of a particular isoform, can also bind to others with similar affinity causing toxic side effects. In this study, the affinities of twelve CA isoforms have been determined for nineteen clin. used drugs used to treat hypertension related diseases, i.e. thiazides, indapamide, and metolazone. Their affinities were determined using a fluorescent thermal shift assay. Stopped flow assay and isothermal titration calorimetry were also employed on a subset of compounds and proteins to confirm inhibition of CA enzymic activity and verify the quant. agreement between different assays. The findings of this study showed that pharmaceuticals could bind to human CA isoforms with variable affinities and inhibit their catalytic activity, even though the drug was intended to interact with a different (non-CA) protein target. Relatively minor structural changes of the compounds may cause significant changes in affinity and selectivity for a particular CA isoform.

Cohen, Jordana B.; Gadde, Kishore M. published the artcile< Weight Loss Medications in the Treatment of Obesity and Hypertension>, Related Products of 96829-58-2, the main research area is review antiobesity agent weight loss obesity hypertension; Blood pressure; Hypertension; Obesity; Weight loss; Weight loss medication; Weight loss pharmacotherapy.

A review. Purpose of Review: Weight loss is strongly associated with improvement in blood pressure; however, the mechanism of weight loss can impact the magnitude and sustainability of blood pressure reduction Recent Findings: Five drugs-orlistat, lorcaserin, liraglutide, phentermine/topiramate, and naltrexone/bupropion-are currently approved for weight loss therapy in the USA. Naltrexone/bupropion results in an increase in in-office and ambulatory blood pressure compared to placebo. Other therapies are associated with modest lowering of blood pressure, and are generally well-tolerated; nonetheless, evidence is limited regarding their effect on blood pressure, particularly longitudinally, in individuals with hypertension. Summary: Although weight loss medications can be an effective adjunct to lifestyle modifications in individuals with obesity, there is limited evidence regarding their benefit with regard to blood pressure. Future studies evaluating the effectiveness of weight loss medications should include careful assessment of their short- and long-term impact on blood pressure in individuals with hypertension.
