Direct reductive aminations with catalytic molybdenum dioxide dichloride and phenylsilane

A powerful direct reductive amination (DRA) method is developed, using catalytic MoO2Cl2 and phenylsilane (PhSiH3) as the reducing agent. The alkylation of a range of amines (pKa 0-7.8) with both an electron-deficient and two electron-rich-aldehydes is achieved in good to excellent yields. The novel employment of this DRA in alcoholic solvents significantly improves the reaction scope and excellent functional group selectivity is exhibited.

New Anti-Inflammatory Hybrid N-Acyl Hydrazone-Linked Isoxazole Derivatives as COX-2 Inhibitors:Rational Design, Synthesis and Biological Evaluation

Selectivity of a drug becomes a major problem in the treatment of a clinical disease and many nonsteroidal anti-inflammatory drugs (NSAID’s) are classic examples of this conundrum. In the present study, we designed a set of hybrid compounds (11 a-p, 12 a-i) that compose new N-acyl hydrazones (NAH) linked with isoxazoles, using rational drug design approach. The binding affinities of newly designed compounds were calculated and compared with known non anti-inflammatory NAH and cyclooxygenase-2 (COX-2) inhibitors (coxibs) at the active sites of cyclooxygenase-1 (COX-1) and COX-2. The comparison revealed that the hybrid compounds bind with COX-2 active site in a fashion quite similar to known non anti-inflammatory compounds (4). Based on these findings, we further synthesized the compounds (11 a-p, 12 a-i) and subjected them to in vitro, in vivo anti-inflammatory studies. Compound 11 l (IC50=5.8 muM) and 12 c (IC50 = 4.1 muM) were found to be active COX-2 inhibitors. Compounds 12 a, 12 b and 12 e displayed COX-2 enzyme inhibition at lower micro molar concentrations. The compounds were also evaluated for antioxidant activity and compound 11 h exhibited an effective antioxidant activity when compared with ascorbic acid. Additionally, these compounds were screened for anti-bacterial activities and compound 11 l and 12 h were exhibited greater anti-bacterial activity against gram +ve and -ve than standards Ciprofloxacin and Flucloxacillin.

A comprehensive overview of directing groups applied in metal-catalysed C-H functionalisation chemistry

The present review is devoted to summarizing the recent advances (2015-2017) in the field of metal-catalysed group-directed C-H functionalisation. In order to clearly showcase the molecular diversity that can now be accessed by means of directed C-H functionalisation, the whole is organized following the directing groups installed on a substrate. Its aim is to be a comprehensive reference work, where a specific directing group can be easily found, together with the transformations which have been carried out with it. Hence, the primary format of this review is schemes accompanied with a concise explanatory text, in which the directing groups are ordered in sections according to their chemical structure. The schemes feature typical substrates used, the products obtained as well as the required reaction conditions. Importantly, each example is commented on with respect to the most important positive features and drawbacks, on aspects such as selectivity, substrate scope, reaction conditions, directing group removal, and greenness. The targeted readership are both experts in the field of C-H functionalisation chemistry (to provide a comprehensive overview of the progress made in the last years) and, even more so, all organic chemists who want to introduce the C-H functionalisation way of thinking for a design of straightforward, efficient and step-economic synthetic routes towards molecules of interest to them. Accordingly, this review should be of particular interest also for scientists from industrial R&D sector. Hence, the overall goal of this review is to promote the application of C-H functionalisation reactions outside the research groups dedicated to method development and establishing it as a valuable reaction archetype in contemporary R&D, comparable to the role cross-coupling reactions play to date.

Back to the future: Advances in development of broad-spectrum capsid-binding inhibitors of enteroviruses

The hydrophobic pocket within viral capsid protein 1 is a target to combat the rhino- and enteroviruses (RV and EV) using small molecules. The highly conserved amino acids lining this pocket enable the development of antivirals with broad-spectrum of activity against numerous RVs and EVs. Inhibitor binding blocks: the attachment of the virion to the host cell membrane, viral uncoating, and/or production of infectious virus particles. Syntheses and biological studies of the most well-known antipicornaviral capsid binders have been reviewed and we propose next steps in this research.

Degradation of pharmaceutical mixtures in aqueous solutions using UV/peracetic acid process: Kinetics, degradation pathways and comparison with UV/H2O2

This paper presents an evaluation of UV/PAA process for degradation of four pharmaceuticals venlafaxine (VEN), sulfamethoxazole (SFX), fluoxetine (FLU) and carbamazepine (CBZ) with comparison to UV/H2O2 process. The effectiveness of combining PAA and H2O2 at various proportions while irradiating with UVC were also evaluated. UVC/PAA (lambda = 254 nm) was effective in degrading all four pharmaceuticals and followed pseudo first-order kinetics. Increasing PAA dosage or UVC intensity resulted in a linear increase in pseudo-first order rate coefficient. Both PAA in dark conditions and UVA/PAA (lambda = 360 nm) were marginally effective to degrade SFX and ineffective to degrade VEN, CBZ and FLU; indicating the need for UVC irradiation for activation of PAA. For similar oxidant dosages of 50 mg/L UVC/H2O2 was found to be faster than UV/PAA for VEN, CBZ and FLU by 55%, 75% and 33%, respectively. Under similar conditions, SFX was degraded 24% faster by UV/PAA. Increase in the proportion of H2O2 to PAA in UVC/PAA/H2O2 improved kinetics of degradation compared to PAA alone. Tests on TOC were conducted to determine the amount of acetic acid that is released to water when treatment by UVC/PAA is conducted. Results demonstrated that 70% of PAA by mass was ultimately converted to acetic acid and remained in the treated solutions. Hydroxyl radical attack is hypothesized to be the main mechanism of degradation by UV/PAA as degradation intermediates identified for all the target pharmaceuticals coincided with by-products identified during UV/H2O2 process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 288-14-2, you can also check out more blogs about288-14-2
