This article details the enantioselective catalytic performance of crosslinked, polymer immobilized, Ir-based, chiral complexes for transfer hydrogenation of cyclic imines to chiral amines. Polymerization of the achiral vinyl monomer, divinylbenzene, and a polymerizable chiral 1,2-diamine monosulfonamide ligand followed by complexation with [IrCl₂Cp*]₂ affords the crosslinked polymeric chiral complex, which can be successfully applied to asym. transfer hydrogenation of cyclic imines. Polymeric catalysts prepared from amphiphilic achiral monomers have high catalytic activity in the reaction and can be used both in organic solvents and water to give chiral cyclic amines with a high level of enantioselectivity (up to 98% ee). The asym. reaction allows for reuse of the heterogeneous catalyst without any loss in activity or enantioselectivity over several runs. © 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Ahmed, Marawan published the artcileGPCR_LigandClassify.py; a rigorous machine learning classifier for GPCR targeting compounds, Computed Properties of 637-07-0, the publication is Scientific Reports (2021), 11(1), 9510, database is CAplus and MEDLINE.

The current study describes the construction of various ligand-based machine learning models to be used for drug-repurposing against the family of G-Protein Coupled Receptors (GPCRs). In building these models, we collected > 500,000 data points, encompassing exptl. measured mol. association data of > 160,000 unique ligands against > 250 GPCRs. These data points were retrieved from the GPCR-Ligand Association (GLASS) database. We have used diverse mol. featurization methods to describe the input mols. Multiple supervised ML algorithms were developed, tested and compared for their accuracy, F scores, as well as for their Matthews correlation coefficient scores (MCC). Our data suggest that combined with mol. fingerprinting, ensemble decision trees and gradient boosted trees ML algorithms are on the accuracy border of the rather sophisticated deep neural nets (DNNs)-based algorithms. On a test dataset, these models displayed an excellent performance, reaching a �90% classification accuracy. Addnl., we showcase a few examples where our models were able to identify interesting connections between known drugs from the Drug-Bank database and members of the GPCR family of receptors. Our findings are in excellent agreement with previously reported exptl. observations in the literature. We hope the models presented in this paper synergize with the currently ongoing interest of applying machine learning modeling in the field of drug repurposing and computational drug discovery in general.

The synthesis of various benzo[h]quinazoline analogs (4a-f, 6a-d, 8a and 8b) was accomplished through the reaction of chalcone with guanidine. The synthesized compounds (4a-f, 6a-d, 8a and 8b) were screened for their anticancer potential against different cancer cells viz MCF-7, DLD1, A549, DU145 & FaDu cell lines. Compounds 4a, 6a-d & 8b showed significant anticancer activity in these cancer cell lines with a range of IC₅₀ values of 1.5-12.99 μM. A functional study of promising mol. 6d at 7 μM (at the IC₅₀ value) over 24 and 48 h showed that it possesses anticancer activity through triggering apoptosis. In a tubulin polymerization assay, 6d effectively inhibited tubulin polymerization with an IC₅₀ of 2.27 μM. In silico docking studies of 6d revealed that 6d has good affinity with an estrogen receptor as well as a tubulin protein on its β-sheet of the colchicines binding site.

A method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu₂Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biol. active compounds via the boronate esters. The unique capabilities of this method are demonstrated by combining carbon-boron bond-forming reactions with palladium-catalyzed methylation in a tandem transformation.

Boebel, Timothy A. published the artcileIridium-Catalyzed Preparation of Silylboranes by Silane Borylation and Their Use in the Catalytic Borylation of Arenes, Category: chlorides-buliding-blocks, the publication is Organometallics (2008), 27(22), 6013-6019, database is CAplus.

Silylboranes are versatile reagents for transition metal-catalyzed reactions of unsaturated organic mols. These reagents are typically prepared by the addition of a silyl lithium species to a boron electrophile. However, the need to generate anionic silane reagents limits the scope of silylboranes that can be readily obtained. Here, the synthesis of trialkylsilylboranes by borylation of silanes catalyzed by iridium complexes is described. The reaction of trialkylhydrosilanes with B₂pin₂ catalyzed by the combination of [Ir(OMe)cod]₂ and 4,4′-di-tert-butylbipyridine forms trialkylsilylboronic esters. In addition, these trialkylsilylboranes serve as boron sources for iridium-catalyzed borylation of aryl C-H bonds. In contrast to diboron reagents, the silylboranes react with methylarenes at both the aryl and Me C-H bonds.

Pitts-McCoy, Anthony M. published the artcileGas-phase ion/ion chemistry as a probe for the presence of carboxylate groups in polypeptide cations, Product Details of C7H16ClNO2, the publication is Journal of the American Society for Mass Spectrometry (2019), 30(2), 329-338, database is CAplus and MEDLINE.

The reactivity of 1-hydroxybenzoyl triazole (HOBt) esters with the carboxylate functionality present in peptides is demonstrated in the gas phase with a doubly deprotonated dianion. The reaction forms an anhydride linkage at the carboxylate site. Upon ion trap collisional-induced dissociation (CID) of the modified peptide, the resulting spectrum shows a nominal loss of the mass of the reagent and a water mol. Analogous phenomenol. was also noted for model peptide cations that likely contain zwitterionic/salt-bridged motifs in reactions with a neg. charged HOBt ester. Control experiments indicate that a carboxylate group is the likely reactive site, rather than other possible nucleophilic sites present in the peptide. These observations suggest that HOBt ester chem. may be used as a chem. probe for the presence and location of carboxylate groups in net pos. charged polypeptide ions. As an illustration, deprotonated sulfobenzoyl HOBt was reacted with the [M+7H]⁷⁺ ion of ubiquitin. The ion was shown to react with the reagent and CID of the covalent reaction product yielded an abundant [M+6H-H₂O]⁶⁺ ion. Comparison of the CID product ion spectrum of this ion with that of the water loss product generated from CID of the unmodified [M+6H]⁶⁺ ion revealed the glutamic acid at residue 64 as a reactive site, suggesting that it is present in the deprotonated form.

cf. Fuson, et al., C.A. 41, 689g. A sample of Levinstein mustard gas was found to contain 61.4% S(CH₂CH₂Cl)₂ (I), m. 14.45°; 4.3% S₂(CH₂CH₂Cl)₂ (II), colorless liquid, m. 0.2°, b_0.3 90-2°; 17.4% S₃(CH₂CH₂Cl)₂ (III), m. 27°, b_0.3 110-12°; 10.7% S (free and combined with III); 6.2% tars and exptl. losses. I, II, and III were synthesized as follows: HOCH₂CH₂Cl and Na₂S₄ gave S(C₂H₄OH)₂, S₂(C₂H₄OH)₂, and S₃(C₂H₄OH)₂. These products and HCl gave I, II, and III, resp. On boiling with NaI in MeOH, II gave S₂(CH₂CH₂I)₂, m. 42°. II and PhONa in alc. gave S₂(CH₂CH₂OPh)₂, m. 96°. The labile polysulfide (IV) (S combined with III), upon boiling in Me₂CO formed S and III. IV was synthesized by heating 1 g. mol. III with 3 g. atoms rhombic S at 110° for several hrs. Since I or II do not form polysulfides on heating with S, it is thought that IV has a structure of the type (ClCH₂CH₂S)₂S→S→Sâ†?or(ClCH₂CH₂S)₂Sâ†?sub>S→Sâ†?/sub>→S→Sâ†?

The internal dynamics during the axisym. coalescence of an initially static free droplet and a sessile droplet of the same fluid are studied using both laboratory experiments and numerical simulations. A high-speed camera captured internal flows from the side, visualized by adding a dye to the free droplet. The numerical simulations employ the volume of fluid method, with the Kistler dynamic contact angle model to capture substrate wettability, quant. validated against the image-processed experiments It is shown that an internal jet can be formed when capillary waves reflected from the contact line create a small tip with high curvature on top of the coalesced droplet that propels fluid toward the substrate. Jet formation is found to depend on the substrate wettability, which influences capillary wave reflection; the importance of the advancing contact angle subordinated to that of the receding contact angle. It is systematically shown via regime maps that jet formation is enhanced by increasing the receding contact angle and by decreasing the droplet viscosity. Jets are seen at volume ratios very different from those accepted for free droplets, showing that a substrate with appropriate wettability can improve the efficiency of fluid mixing.
