A new palladium-catalyzed reductive desulfonative aminocarbonylation reaction with benzylsulfonyl chlorides RCH₂S(O)₂Cl (R = Ph, 3,4-dimethylphenyl, 2,4-dichlorophenyl, etc.) as C(sp³) electrophiles has been developed. Using nitroarenes R¹NO₂ (R¹ = Ph, quinolin-8-yl, 2H-1,3-benzodioxol-5-yl, etc.) as readily accessible and stable nitrogen surrogates, a wide range of arylacetamides RCH₂C(O)NHR¹ were easily prepared in high yields with very good functional group compatibility. Mo(CO)₆ plays a dual role as both a CO source and reductant. Moreover, a late-stage modification of natural products was also achieved via this aminocarbonylation strategy.

The effects of electron-withdrawing or -donating substituents on different parts of the mol., as well as those produced by the incorporation of an addnl. fused ring, were analyzed. Several compounds showed significant antimalarial activity in vitro with IC₅₀ values as low as 60 nM and a certain efficacy in vivo by reducing parasitemia in Plasmodium berghei mouse models.

Amani, A. published the artcileCrystal structure of 2,2-diphenyl-4-dimethylaminopentanenitrile, C₁₉H₂₂N₂, Safety of 2-Chloro-N,N-dimethylpropan-1-amine hydrochloride, the publication is Zeitschrift fuer Kristallographie – New Crystal Structures (2005), 220(4), 549-550, database is CAplus.

The title compound was synthesized by reaction of 1-dimethylamino-2-chloropropane hydrochloride and diphenylacetonitrile in the presence of NaOH as a base. Crystallog. data and at. coordinates are given. Its crystal structure is built up by only the C₁₉H₂₂N₂ mols. within which all bond lengths are almost in normal ranges. C6 atom is substituted with two Ph groups and the C8-C6-C14 angle is 108.2(4)°. The C7-C6-C14 angle of 104.3(2)° and C2-C1-C16 angle of 110.8(2)° deviate slightly from the ideal value of 109.5°. The planes of the two Ph rings on C6 are oriented differently to each other with one in a horizontal and the other in a vertical manner. The arrangement of two mols. in the unit cell is in a manner that intermol. π-π stacking interactions between two horizontal Ph groups are achieved. These interactions were not observed for the vertical Ph groups.

Some nitrogen and sulfur containing aromatic ligands are ubiquitous components both for physiol. active products and important pharmaceuticals. The study of binuclear complexes of these ligands with transition metal copper(II) is highly interesting due to their significance in phys. and bioinorganic chem., material science and multi-electron redox chem. Likewise novel complexes of copper(II) palmitate with N and S donor ligands were synthesized and viscometric behavior of these complexes was studied in non aqueous benzene-methanol solvent mixture Their study helps in interpretation of solute-solvent interactions, structural insight of micelle and colloidal chem. behavior in binary systems. Study of these factors is essential as it indirectly makes them responsible for their immense applicability in wide areas of field.

Martinez-Lopez, Yoan published the artcilePrediction of aquatic toxicity of benzene derivatives using molecular descriptor from atomic weighted vectors, Application of 3-Chloro-4-fluoronitrobenzene, the publication is Environmental Toxicology and Pharmacology (2017), 314-321, database is CAplus and MEDLINE.

Several descriptors from atom weighted vectors are used in the prediction of aquatic toxicity of set of organic compounds of 392 benzene derivatives to the protozoo ciliate Tetrahymena pyriformis (log(IGC50)^-1). These descriptors are calculated using the MD-LOVIs software and various Aggregation Operators are examined with the aim comparing their performances in predicting aquatic toxicity. Variability anal. is used to quantify the information content of these mol. descriptors by an information theory-based algorithm. Multiple Linear Regression with Genetic Algorithms is used to obtain models of the structure-toxicity relationships; the best model shows values of Q² = 0.830 and R² = 0.837 using six variables. The authors’ models compare favorably with other previously published models that use the same data set. The obtained results suggest that these descriptors provide an effective alternative for determining aquatic toxicity of benzene derivatives

Nadaf, Afra Quasar A. published the artcileDesign, synthesis and biological evaluation of novel N,4-diphenylthiazol-2-amine derivatives, Computed Properties of 3696-23-9, the publication is Medicinal Chemistry Research (2020), 29(3), 442-458, database is CAplus.

Novel N,4-diphenylthiazol-2-amine derivatives I (R¹ = Cl, OMe; R² = Br, NO₂; R³ = Et, i-Pr, n-Pr, s-Bu, octan-3-yl) were designed and synthesized employing Hantzsch method. The three-step reaction involved in the synthesis occurred at a faster rate with excellent yields in eco-friendly conditions. Single-crystal X-ray diffraction studies also confirmed the formation of title compds I. These compounds I were evaluated in vitro for their antimicrobial and anti-inflammatory activities. The results demonstrated that most of the tested compounds I showed potent antifungal activity. Interestingly, these compounds I also exhibited good anti-inflammatory and moderate antibacterial activity towards sensitive as well as resistant bacterial strains. In silico studies depicted their good binding affinity profile against S. aureus (PDB ID: 1AD4) and C. albicans (PDB ID: 1AI9).

Zhang, Zhongsheng published the artcileStructure-guided discovery of selective methionyl-tRNA synthetase inhibitors with potent activity against Trypanosoma brucei, COA of Formula: C7H8BClO2, the publication is RSC Medicinal Chemistry (2020), 11(8), 885-895, database is CAplus and MEDLINE.

Based on crystal structures of Trypanosoma brucei methionyl-tRNA synthetase (TbMetRS) bound to inhibitors, we designed, synthesized, and evaluated two series of novel TbMetRS inhibitors targeting this parasite enzyme. One series has a 1,3-dihydro-imidazol-2-one containing linker, the other has a rigid fused aromatic ring in the linker. For both series of compounds, potent inhibition of parasite growth was achieved with EC₅₀ < 10 nM and most compounds exhibited low general toxicity to mammalian cells with CC₅₀s > 20 000 nM. Selectivity over human mitochondrial methionyl tRNA synthetase was also evaluated, using a cell-based mitochondrial protein synthesis assay, and selectivity in a range of 20-200-fold was achieved. The inhibitors exhibited poor permeability across the blood brain barrier, necessitating future efforts to optimize the compounds for use in late stage human African trypanosomiasis.

Sobol, Marcin published the artcileCytotoxicity study of novel water-soluble chitosan derivatives applied as membrane material of alginate microcapsules, Synthetic Route of 4584-49-0, the publication is Journal of Biomedical Materials Research, Part A (2013), 101A(7), 1907-1914, database is CAplus and MEDLINE.

The majority of cell encapsulation systems applied so far are based on polyelectrolyte complexes of alginate and polyvalent metal cations. Although widely used, these systems suffer from the risk of disintegration. This can be partially solved by applying chitosan as addnl. outer membrane. However, chitosan can be dissolved in water only at a low pH, which limits its use in the field of bioencapsulation. In this study, novel primary and tertiary amine chitosan derivatives have been synthesized, which may be dissolved at pH 7.0, and retain the ability to effectively form addnl. membrane on the surface of alginate beads. As aqueous solutions tertiary amines dimethylamino-1-propyl-chitosan and dimethylethylamine-chitosan with linear hydrochloride aliphatic chains had the lowest toxicity, whereas dimethylpropylamine-chitosan, diethylaminoethyl-chitosan, and diisopropylaminoethyl-chitosan with branched hydrochloride aliphatic were cytotoxic to the majority of tested cells. When applied as polyelectrolyte complexation agent on the surface of alginate beads, none of the derivates had any neg. effect on the metabolic activity of encapsulated beta-cells. © 2012 Wiley Periodicals, Inc.
