Hall, Thomas H.; Adams, Hannah; Vyas, Vijyesh K.; Michael Chu, K. L.; Wills, Martin published the artcile< Asymmetric transfer hydrogenation of unsaturated ketones; factors influencing 1,4- vs 1,2- regio- and enantioselectivity, and alkene vs alkyne directing effects>, HPLC of Formula: 1192620-83-9, the main research area is unsaturated ketone enantioselective regioselective transfer hydrogenation chemoselectivity.

A detailed study has been completed on the asym. transfer hydrogenation (ATH) of a series of enones using Ru(II) catalysts. Electron-rich rings adjacent to the C=O group reduce the level of C=O reduction compared to C=C. The ATH reaction can readily discriminate between double and triple bonds adjacent to ketones, reducing the double bond but leaving a triple bond intact in the major product.

Reany, Ofer; Blair, Stephanie; Kataky, Ritu; Parker, David published the artcile< Solution complexation behavior of 1,3,5-trioxycyclohexane based ligands and their evaluation as ionophores for Group IA/IIA metal cations>, Category: amides-buliding-blocks, the main research area is metal selectivity cyclohexanetriol solution complexation ligand conformation hydrogen bond.

A new series of cis,cis-cyclohexane-1,3,5-triol derivatives bearing one, two and three carbamoylalkyl substituents is reported. Ring interconversion promoted by intramol. hydrogen bonding is observed for the mono- and di-alkylated derivatives 3 and 4 depending on solvent polarity. 1H NMR parameters obtained have allowed the calculation of the Gibbs free energy change (ΔG 0) for the trioxa-equatorial ↔ trioxa-axial equilibrium, modeling the conformational changes promoted by ion binding. Selectivity coefficients have been assessed electrochem. using fixed interference methods for the detection of biol. relevant IA/IIA metal cations. Ionophore 4 displays a Nernstian response towards the detection of Ca2+ and logKCa,Mpot values are calculated Solution NMR studies confirm the formation of 1:1 complexes for 4 with lithium, while 2:1 complexation is favored with Ca2+. Detailed ES-MS studies performed under controlled conditions revealed similar trends in ion binding.

Meng, Fanfei; Mi, Pengcheng; Yu, Zhenwu; Wei, Wei; Gao, Li; Ren, Jinzhou; Li, Zhengming; Dai, Huanqin published the artcile< Design, synthesis and biological evaluation of 5-substituted sulfonylureas as antifungal agents targeting acetohydroxyacid synthase>, Recommanded Product: o-Chlorobenzenesulfonamide, the main research area is sulfonylurea preparation antifungal.

In this work, 36 target compounds I were designed and synthesized and several 5-substituted sulfonylureas I = [X =CH, N, R1 = Me, Cl, Br; R2 = CNOMe, CHCH2, CHO; R3 = H, Me, OMe; R4 = Me, OMe, etc.] possess much better antifungal activities than those of Fluconazole (FCZ) and amphotericin B (AMB). The most potent of these were I [X =CH, R1 = Br, R2 = CNOMe, R3 = R4 = OCH3], I [X =CH, R1 = Cl, R2 = CHCH2, R3 = R4 = OCH3] and I [X =CH, R1 = I, R2 = CHCH2, R3 = R4 = OCH3] with inhibition constants (Ki) determined in the range of 5.6∼9.6 nM for C. albicans AHAS and MICs(The MIC was determined as the drug concentration that inhibited fungal growth by >90% relative to the corresponding drug-free growth control) <0.05∼0.78μg/mL for C. albicans SC 5314, 17# and 2# (17# and 2# were two clin. isolated FCZ-resistant strains of C. albicans), S. cerevisiae SCXH1549 and C. parapsilosis ATCC22019 in YNB (yeast nitrogen base) media at 72 h post-treatment. Using the same media, the com. MICs of FCZ and AMB were only determined in the range of 0.25∼5μg/mL for the five strains at 24 h post-treatment. In order to elaborate the structure-activity relationship (SAR) a proposed double-pocket binding mode was simulated via mol. docking. The energy gap between the HOMOs and LUMOs of selected compounds showed that the 5-substituted groups of sulfonylureas I = [X =CH, N, R1 = Me, Cl, Br; R2 = CNOMe, CHCH2, CHO; R3 = H, Me, OMe; R4 = Me, OMe, etc.] had key impact on the antimicrobial bioactivity.

Zheng, Ye; Martinez-Acosta, Jaime A.; Khimji, Mohammed; Barbosa, Luiz C. A.; Clarkson, Guy J.; Wills., Martin published the artcile< Asymmetric Transfer Hydrogenation of Aryl Heteroaryl Ketones using Noyori-Ikariya Catalysts>, Computed Properties of 1192620-83-9, the main research area is aryl heteroaryl alc preparation enantioselective; heteroaryl aryl ketone asym transfer hydrogenation Noyori Ikariya catalyst.

A range of ketones ArC(O)R (Ar = Ph, 2-bromophenyl, naphthalen-1-yl, etc.; R = furan-2-yl, thiophen-2-yl, 1-methyl-1H-imidazol-2-yl) flanked by a combination of an aromatic and a heterocyclic ring were reduced under asym. transfer hydrogenation (ATH) conditions. Using a range of [(arene)Ru(TsDPEN)Cl] precatalysts, including tethered derivatives, I, the reduction enantioselectivity was high (up to 99% ee) in cases where the aromatic ring contained an ortho-substituent. The enantioselectivity is influenced by a combination of steric and electronic factors which for the furan and thiophene series, follow literature precedents. In the case of the N-methylimidazole-containing ketones ArC(O)R (R = 1-methyl-1H-imidazol-2-yl), an unexpected switch in enantioselectivity took place upon variation of the opposing aromatic group. Pyrrole- containing ketones II (R1 = Me, tert-butoxycarbonyl) were resistant to reduction This study demonstrates the asym. transfer hydrogenation (ATH) of a range of hindered heterocyclic ketones, in high conversion and ee, using Noyori-Ikariya catalysts I.

This study presents a first report on ruthenium-catalyzed asym. transfer hydrogenation (ATH) of levulinic acid (LA) to chiral γ-valerolactone (GVL). ATH of LA has been explored with Noyori’s chiral catalyst (Ru-TsDPEN) in methanol solvent. Efficacy of ATH reaction of LA was investigated under different reactions conditions such as temperature, catalyst, and hydrogen donor concentration The effect of various organic tertiary bases along with formic acid (FA) as a hydrogen donor was studied, and N-methylpiperidine with FA (1:1 molar ratio) was revealed as an efficient hydrogen donor for ATH of LA to GVL furnishing chiral GVL with complete conversion and 93% enantiomeric excess (ee). This operationally simple and mild ATH protocol was tested for practical applicability of ATH of LA obtained from biomass waste (rice husk and wheat straw) and furnished chiral GVL with 82% ee.

EPAC plays a central role in various biol. functions, and activation of the EPAC1 protein has shown potential benefits for the treatment of various human diseases. Herein, the synthesis and biochem. evaluation of a series of non-cyclic nucleotide EPAC1 activators is reported. Several potent EPAC1 binders were identified, e.g., I, which promote EPAC1 GEF activity in vitro. These agonists can also activate EPAC1 protein in cells, where they exhibit excellent selectivity towards EPAC over PKA and GPCRs. Moreover, four compounds exhibited improved selectivity towards activation of EPAC1 over EPAC2 in cells. Of these, I was found to robustly inhibit IL-6-activated STAT3 and subsequent induction of the pro-inflammatory VCAM1 cell adhesion protein. These novel EPAC1 activators may therefore act as useful pharmacol. tools for elucidation of EPAC function as well as promising drug leads for the treatment of relevant human diseases.

Liu, Peng; Yang, Jiazhi; Ai, Yao; Hao, Shushu; Chen, Xiaozhong; Li, Feng published the artcile< Recyclable covalent triazine framework-supported iridium catalyst for the N-methylation of amines with methanol in the presence of carbonate>, Formula: C6H6ClNO2S, the main research area is amine methyl preparation green chem; methanol amine methylation covalent triazine framework iridium catalyst; methyl sulfonamide preparation green chem; sulfonamide methanol methylation covalent triazine framework iridium catalyst.

An iridium complex Cp*Ir@CTF, which is synthesized by the coordinative immobilization of [Cp*IrCl2]2 on a functionalized covalent triazine framework (CTF), was found to be a general and highly efficient catalyst for the N-methylation of amines RNH2 [R = octyl, adamantan-1-yl, naphthalen-2-yl, 1,3-benzoxazol-2-yl, etc.], 1,2,3,4-tetrahydroisoquinoline and 1,3-bis(4-piperidyl)propane with methanol in the presence of carbonate. Under environmentally benign conditions, a variety of desirable products RNHCH3, RN(CH3)2, 2-methyl-1,2,3,4-tetrahydroisoquinoline and 1-methyl-4-(3-(1-methylpiperidin-4-yl)propyl)piperidine/R1S(O)2NH(CH3) (R1 = t-Bu, cyclopropyl, 4-chlorophenyl, thiophen-2-yl, etc.) were obtained in high yields with complete selectivities and functional group friendliness. Furthermore, the synthesized catalyst Cp*Ir@CTF could be recycled by simple filtration without obvious loss of catalytic activity after sixth cycle. Notably, this research exhibited the potential of covalent triazine framework-supported transition metal catalyst Cp*Ir@CTF for hydrogen autotransfer process.

Deb, S. B.; Gamare, J. S.; Kannan, S.; Drew, M. G. B. published the artcile< Uranyl(VI) and lanthanum(III) thio-diglycolamides complexes: Synthesis and structural studies involving nitrate complexation>, Application of C10H20ClNO, the main research area is thiodiglycolamide preparation complexation uranyl lanthanum nitrate; crystal structure uranyl lanthanum thiodiglycolamide nitrato complex; solvent extraction uranyl cation nitric acid medium thiodiglycolamide ligand.

New tri-functional ligands R2NCOCH2SCH2CONR2 (R = iso-Pr, Bu or iso-butyl) were prepared and characterized. The coordination chem. of these ligands with uranyl and lanthanum(III) nitrates was studied by using the IR, 1H NMR and elemental anal. methods. Structures for [UO2(NO3)2(iPr2NCOCH2SCH2CONiPr2)], [UO2(NO3)2(iBu2NCOCH2SCH2CONiBu2)], [La(NO3)3(iPr2NCOCH2SCH2CONiPr2)2] and [La(NO3)3(iBu2NCOCH2SCH2CONiBu2)2] were determined by single crystal x-ray diffraction. These structures show that the ligand acts as a bidentate chelating ligand and bonds through both the carbamoyl groups to the uranyl and La(III) nitrate groups. Solvent extraction studies show that the ligand can extract the uranyl ion from the HNO3 medium but does not show any ability to extract the Am(III) ion.
