Curcumin is a multi-functional pharmacologically safe natural agent with proven cytoprotective effects to healthy human cells. In this study, a new series of sulfonamides with curcumin scaffold were synthesized, characterized and investigated for their carbonic anhydrase isoenzyme I (human) and II (bovine) isoforms. The structures of newly synthesized compounds were described by IR, 1H NMR and 13C NMR spectral data. Compound 14 showed the Ki value of 0.99 muM with highest inhibitory activity among all other synthesized compounds against hCA-I enzyme. Similarly enzyme kinetic studies of compound 14, 16 and 30 against bCAII enzyme showed Ki values of 0.71, 0.67 and 0.71 muM respectively. Our biological assays results showed that most of active compounds have similar inhibitory activities compared to standard acetazolamide drug. The molecular docking predicted binding modes showed that these compounds bind with hCA-1 enzyme in similar fashion.

The present review provides a survey on the structural features, synthetic methodologies, and reactions of phenyl sulfonylacetophenone, considered to be one of the most important synthons in the field of synthetic organic chemistry. beta-Ketosulfone is an active C?H acid which has been widely used as a nucleophile in many organic transformations. It has been used for synthesis of five- and six-membered ring systems containing one or two heteroatoms. In addition, it has been used as a starting material for synthesis of fused heterocycles, cyclopropane, cyclopentene, and cyclohexanone derivatives. beta-Ketosulfone has been used for synthesis of gamma- and delta-ketosulfones, 1,4-diketones, amides, ethers, and substituted benzene derivatives due to its high synthetic importance. It is a reactive intermediate in electrophilic reactions such as halogenation, alkylation, arylation, heteroarylation, and coupling reactions, and is involved in other types of reaction such as Diels?Alder condensation with aldehydes and desulfonylation. The mechanistic pathways of these reactions and their important synthetic applications are discussed herein.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C3H3NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 288-14-2, in my other articles.

Heterocycles play an essential role in modern pharmaceutical and agrochemical developments, representing a very common structural unit in marketed drugs. Over the 46 new drugs approved in 2017 by the FDA, 25 contain in their structure a heterocyclic core. The development of novel and straightforward labeling strategies for the effective insertion of carbon isotopes into heterocylic scaffolds is an inspiring and vibrant field of research. The use of carbon-11, carbon-13, and carbon-14 isotopes is well established in life science and particularly in pharmaceutical and agrochemical industry. Their introduction into small organic molecules represents a crucial step for the radiochemists. Because the labeling should occur in metabolically stable positions and in the shortest synthetic route, their incorporation into the heterocycles represents a viable solution. This review summarizes recent contributions to this area of research through the analysis of different industrial and academic cases.

Hydrophosphination of CO2 with 1,3,2-Diazaphospholene (NHP-H; 1) afforded phosphorus formate (NHP-OCOH; 2) through the formation of a bond between the electrophilic phosphorus atom in 1 and the oxygen atom from CO2, along with hydride transfer to the carbon atom of CO2. Transfer of the formate from 2 to Ph2SiH2 produced Ph2Si(OCHO)2 (3) in a reaction that could be carried out in a catalytic manner by using 5 mol % of 1. These elementary reactions were applied to the metal-free catalytic N-formylation of amine derivatives with CO2 in one pot under ambient conditions.

Treatment of glomerular diseases remains challenging. There are limited therapeutic options currently available for focal segmental glomerulosclerosis (FSGS) and immunoglobulin A nephropathy (IgAN) and they are generally ineffective in a substantial proportion of patients who progress to end-stage kidney disease during long-term followup. Standard management involving renin-angiotensin-aldosterone system (RAAS) inhibitors, corticosteroids and various immunosuppressive therapies does not always achieve.

A novel and convenient photo-mediated halogenated spirocyclization of N-(p-methoxyaryl)propiolamides has been developed. The photolysis of phenyliodine bis(trifluoroacetate) (PIFA) as an iodination reagent led to iodinated ipso-cyclization under the irradiation of a xenon lamp, while brominated ipso-cyclization or chlorinated ipso-cyclization was achieved by irradiating a mixture of PIFA and KBr/KCl under a blue LED. The present protocol simply utilizes light as the safe and clean energy source and doesn’t require any external photocatalyst providing various 3-halospiro[4,5]trienones in good to excellent yields (up to 93%).
