4100-80-5, Name is 3-Methyldihydrofuran-2,5-dione, belongs to tetrahydrofurans compound, is a common compound. COA of Formula: C5H6O3In an article, once mentioned the new application about 4100-80-5.

Using molecular modeling and rationally designed structural modifications, the multi-target structure?activity relationship for a series of ranitidine analogs has been investigated. Incorporation of a variety of isosteric groups indicated that appropriate aromatic moieties provide optimal interactions with the hydrophobic and pi?pi interactions with the peripheral anionic site of the AChE active site. The SAR of a series of cyclic imides demonstrated that AChE inhibition is increased by additional aromatic rings, where 1,8-naphthalimide derivatives were the most potent analogs and other key determinants were revealed. In addition to improving AChE activity and chemical stability, structural modifications allowed determination of binding affinities and selectivities for M1?M4 receptors and butyrylcholinesterase (BuChE). These results as a whole indicate that the 4-nitropyridazine moiety of the JWS-USC-75IX parent ranitidine compound (JWS) can be replaced with other chemotypes while retaining effective AChE inhibition. These studies allowed investigation into multitargeted binding to key receptors and warrant further investigation into 1,8-naphthalimide ranitidine derivatives for the treatment of Alzheimer’s disease.

Application of 2144-40-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 2144-40-3, (cis-Tetrahydrofuran-2,5-diyl)dimethanol, introducing its new discovery.

2,5-Dimethylfuran (DMF) is an attractive biofuel being stable, insoluble in water and an alternative to gasoline. DMF is accessible via hydrodeoxygenation of the cellulosic bio-based platform chemical 5-hydroxymethylfurfural (HMF). Efficient transformations of HMF to DMF have been reported to date; however, the kinetics of the reaction and a comprehensive analysis of the reaction network have not been addressed yet. In the present work, a plausible reaction network based on kinetic study of the hydrodeoxygenation of HMF over a carbon-supported nickel catalyst is proposed. The study of the reaction network showed the reaction indeed proceeds via the hydrogenation of the aldehyde group of HMF to form 2,5-bishydroxymethylfuran (BHMF) and subsequent conversion of BHMF to 5-methylfurfurylalcohol (MFA) followed by hydrogenolysis of MFA to DMF. Side reactions include the formation of 2,5-dihydroxymethyltetrahydrofuran (DHMTHF) and 2,5-dimethyltetrahydrofuran (DMTHF). A suitable kinetic model enabled estimating the kinetic parameters in the reaction temperatures range of 150?190 C. Kinetics analysis revealed the hydrogenation of HMF to BHMF as rate-determining step, while subsequent deoxygenation to DMF proceeds faster. Interestingly, most undesired reactions were kinetically hindered under selected reaction conditions allowing high selectivity to the target product DMF.

An efficient asymmetric hydrogenation of beta,gamma-unsaturated gamma-lactams using an iridium-phosphoramidite complex is reported. The chiral gamma-lactams were obtained in excellent yields and enantioselectivities (up to 99% yield and 99% ee). The mechanistic studies indicated that the reduced products were obtained via the hydrogenation of the N-acyliminium cations, generated from beta,gamma-unsaturated gamma-lactams, which was verified by 1H NMR analysis. The reaction was carried out at a reduced catalyst loading of 0.1 mol %, and the reduced products can be transformed to two potential bioactive compounds. A new route is provided for the synthesis of chiral gamma-lactams.

We report the discovery of 7-oxo-2,4,5,7-tetrahydro-6H-pyrazolo[3,4-c]pyridine derivatives as a novel class of receptor interacting protein 1 (RIP1) kinase inhibitors. On the basis of the overlay study between HTS hit 10 and GSK2982772 (6) in RIP1 kinase, we designed and synthesized a novel class of RIP1 kinase inhibitor 11 possessing moderate RIP1 kinase inhibitory activity and P-gp mediated efflux. The optimization of the core structure and the exploration of appropriate substituents utilizing SBDD approach led to the discovery of 22, a highly potent, orally available, and brain-penetrating RIP1 kinase inhibitor with excellent PK profiles. Compound 22 significantly suppressed necroptotic cell death both in mouse and human cells. Oral administration of 22 (10 mg/kg, bid) attenuated disease progression in the mouse experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis (MS). Moreover, analysis of structure-kinetic relationship (SKR) for our novel chemical series was also discussed.
