The consecutive addition of acyl radicals and N-alkylindole nucleophiles to styrenes was established, as well as some additional radical-nucleophile combinations. Both aryl and aliphatic aldehydes give reasonable yields. The reaction proceeds best for alpha-substituted styrenes, effectively creating a quaternary all-carbon center. Some iridium-based photoredox systems are catalytically active; furthermore, a base is needed in this transformation. Radicals are formed by reductive perester cleavage and hydrogen atom transfer.

Separation of bovine serum albumin (BSA) and hemoglobin (Hb), two proteins with almost identical molecular weight, has been a big challenge for more than two decades. Using traditional ultrafiltraion membranes separation of these proteins is possible only at the isoelectric point of one protein via electrostatic repulsion between the membrane and the other protein. Here we introduce an integral asymmetric isoporous membrane from polystyrene-block-poly(2-hydroxyethyl meth-acrylate-ran-2-(succinyloxy)ethyl methacrylate) (PS-b-P(HEMA-r-SEMA)) having random-OH and-COOH groups along the pore walls prepared by a method which combines solvent induced self-assembly of the block copolymer and nonsolvent induced phase separation (SNIPS). The membrane consists of soft isoporous channels due to swelling of the P(HEMA-r-SEMA) blocks in a hydrated state. The effective pore size of the membrane in a hydrated state is significantly lower compared to that in a dry state. These soft channels allow the permeation of BSA while retaining Hb at constant pH 7.4 where both proteins are negatively charged. In comparison to 22 commercial and in-house prepared membranes the PS-b-P(HEMA-r-SEMA) membrane presents unprecedented ideal selectivity of BSA over Hb (psi(BSA/Hb) = 16). Unlike the conventional technique in this case the electroneutrality of one protein is not mandatory which will provide significantly easier handling.

Safety of 2,5-Dimethoxybenzaldehyde. Authors Wadhwa, P; Jain, P; Jadhav, HR in BENTHAM SCIENCE PUBL LTD published article about in [Wadhwa, Pankaj; Jain, Priti; Jadhav, Hemant R.] Birla Inst Technol & Sci, Dept Pharm, Pilani 333031, Rajasthan, India; [Wadhwa, Pankaj] Lovely Profess Univ, Lovely Sch Pharmaceut Sci, Phagwara 144401, Punjab, India; [Jain, Priti] RC Patel Inst Pharmaceut Educ & Res, Shirpur, Dhule, India in 2021.0, Cited 18.0.

Aim: To design, synthesis and in vitro evaluation of 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile derivatives as HIV integrase strand transfer inhibitors. Background: Human immunodeficiency virus-1 (HIV-1), a member of retroviridae family, is the primary causative agent of acquired immunodeficiency syndrome (AIDS). Three enzymes viz: integrase (IN), reverse transcriptase (RT) and protease play important role in its replication cycle. HIV-1 integrase is responsible for the incorporation of viral DNA into human chromosomal DNA by catalyzing two independent reactions, 3′-processing (3′-P) and strand transfer (ST), which are observed as the point of no-return in HIV infection. Objective: To develop inhibitors against HIV integrase strand transfer step. Methods: Our previous results indicated that tetrahydro pyrimidine-5-carboxamide derivatives are potent HIV-1 IN inhibitors (unpublished results from our laboratory). Taking clue from above studies and our own experience, we hypothesized 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues (14a to 14n) as inhibitors of HIV-1 Integrase strand transfer. Prototype compound 14 can be viewed as hybrid structure having characteristics of dihydropyrimidine derivatives 10-12 and tyrphostin 13. Results: A total of fourteen derivatives of 4-oxo-6-substituted phenyl-2-thioxo-1,2,3,4-tetrahydro-pyrimidine-5-carbonitrile (14a-14n) were synthesized and evaluated using HIV-1 Integrase Assay Kit (Xpressbio Life Science Products, USA). The percentage inhibition of all compounds was investigated at 10 mu M concentration and IC50 value of few highly active compounds was studied. The obtained results were validated by in silico molecular docking study using Glide (maestro version 9.3, Schrodinger suite) in extra precision (XP) mode. Conclusion: Fourteen 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues were synthesized and evaluated for HIV-1 IN inhibitory activity. Three compounds 14a, 14e, and 14h exhibited significant percentage inhibition of HIV-1 IN. There was good in vitro – in silico correlation. However, none of the derivative was active against HIV-1 and HIV-2 below their cytotoxic concentration. It needs to be seen whether these compounds can be explored further for their anti-HIV or cytotoxic potential.

Though density functional theory is widely accepted as one of the most successful developments in theoretical chemistry in the past few decades, the knowledge of how to apply this new electronic structure theory, to help us better understand chemical processes and transformations, is still an unaccomplished task. The information-theoretic approach is emerging as a viable option for that purpose in the recent literature, providing new insights about steric effect, cooperativity, electrophilicity, nucleophilicity, stereoselectivity, homochirality, etc. In this work, based on the result from a recent paper by one of us [J. Chem. Phys, 2019, 151, 141103], we present two quantifications of the relative Fisher information and discuss their physiochemical properties and possible applications. To that end, their analytical properties have been elucidated. They have also been applied to six categories of systems to illustrate their applicability. A better descriptor to quantify the single bond rotation barrier has been obtained. The relative Fisher information can also simultaneously determine electrophilicity and nucleophilicity, and effectively describe helical structures with different homochiral and heterochiral propensities. As integral parts of the information-theoretic approach, these newly introduced quantities will provide us with more analytical tools toward the long-term goal of crafting a chemical reactivity theory in the density-based language.

This work entails deep red emitting Eu-III based complexes with a variety of ternary beta-diketonate ligands and 1,10-phenanthroline as the ancillary ligand in the system. The solid state structure and spectroscopic analysis has been outlaid in terms of photoluminescence and crystallography. A luminescence quantum efficiency of 50% was obtained for the [tris-(4,4,4-trifluoro-1-chlorophenyl-butanedione)mono-(1,10-phenanthroline)europium(iii)] complexes. Moreover, complexes [tris-(2,2,6,6-tetramethyl-heptanedione)mono-(1,10-phenanthroline) europium(iii)] and {[hexa-(benzyl carboxylic acid) bis-(1,10-phenanthroline)di-europium(iii)]-mu-[kappa(2)-O,O ‘-(benzyl carboxylic acid)](2)} were found to also have quantum yields of 9% and 28% with respective sensitization efficiencies of 85%, 15% and 58%. These results were articulated with crystallographic details pertaining to the nature of coordination and the effect of steric and electronic properties thereof which somewhat impacts the Eu-N bond distances. A symmetry correlation was drawn between the crystallographic data and the photoluminescence data.

Ir-catalyzed cascade dehydrogenative CH/BH and BH/OH cross-coupling of carboranyl carboxylic acid with readily available benzoic acid has been achieved, leading to the facile synthesis of previously unavailable carborano-coumarin in a simple one-pot process. Two cage B-H, one aryl C-H and one O-H bonds are activated to construct efficiently new B-C and B-O bonds. The cascade cyclization can stop at the first B-H/C-H cross-coupling step by tuning the reaction conditions, resulting in a series of alpha-carboranyl benzoic acid and aryl carborane derivatives. Control experiments indicate that B-H/C-H dehydrocoupling proceeds preferentially over B-H/O-H dehydrocoupling, and both directing groups and oxidants are crucial for this reaction. An iridium(V) intermediate is proposed to be involved in the catalytic cycle.

A practical method for the umpolung selenocyanation of aryl ketones, alkyl ketones, beta-ketoesters and electron-rich arenes has been developed, affording various selenocyanates in moderate to excellent yields. This transformation proceeds by an oxidative umpolung selenocyanation through nitrogen oxides-mediated electrophilic selenocyanation process. This method is simpler, more efficient, and less costly than precedent methods. Further transformations of the arylselenocyanate was performed to prove the synthetic utility of this methodology.
