To improve definition of the physical and hormonal support of bone formation, we studied differentiation of human osteoblasts in vitro at varying combinations of ACTH, 1alpha,25-dihydroxyvitamin D 3 (1,25(OH) 2 D), and extracellular calcium, with and without added cortisol. Bone mineralization, alkaline phosphatase activity, and osteoblast-specific markers RunX2, osterix, and collagen I increased with 10 pM ACTH, 10 nM 1,25(OH) 2 D, or at 2 mM calcium with important synergistic activity of combinations of any of these stimuli. Signals induced by ACTH at 10-30 min included cAMP, TGF-beta, and Erk1/2 phosphorylation. Affymetrix gene expression analysis showed that 2 h treatment of ACTH or 1,25(OH) 2 D increased the expression of bone regulating and structural mRNAs, including collagen I, biglycan, the vitamin D receptor, and TGF-beta. Accelerating expression of these bone-specific genes was confirmed by quantitative PCR. Expression of 1,25(OH) 2 D 1alpha-hydroxylase (1alpha-hydroxylase) increased with 1,25(OH) 2 D, ACTH, and extracellular calcium from 0.5 to 2 mM. Unlike renal 1alpha-hydroxylase, in osteoblasts, 1alpha-hydroxylase activity is independent of parathyroid hormone. In keeping with calcium responsivity, calcium-sensing receptor RNA and protein increased with 10 nM ACTH or 1,25(OH) 2 D. Inclusion of 200 nM cortisol or 10 nM ACTH in differentiation media blunted osteoblasts alkaline phosphatase response to 1,25(OH) 2 D and calcium. Our results point to the importance of ACTH in bone maintenance and that extra skeletal (renal) 1,25(OH) 2 D is required for bone mineralization despite 1alpha-hydroxylase expression by osteoblasts.

Application of 150-61-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.150-61-8, Name is N1,N2-Diphenylethane-1,2-diamine, molecular formula is C14H16N2. In a article，once mentioned of 150-61-8

Mild palladium-catalyzed aminations of aryl tosylates and the first aminations of heteroaryl tosylates are described. In the presence of the combination of L2Pd(0) (L = P(o-tol)3) and the hindered Josiphos ligand CyPF-t-Bu, a variety of primary alkylamines and arylamines react with both aryl and heteroaryl tosylates at room temperature to form the corresponding secondary arylamines in high yields with complete selectivity for the monoarylamine. These reactions at room temperature occur in many cases with catalyst loadings of 0.1 mol % and 0.01 mol % in one case, constituting the most efficient aminations of aryl tosylates by nearly 2 orders of magnitude. This catalyst is made practical by the development of a convenient method to synthesize the L2Pd(0) precursor. This complex is stable to air as a solid. In contrast to conventional relative rates for reactions of aryl sulfonates, the reactions of aryl tosylates are faster than parallel reactions of aryl triflates, and the reactions of aryl tosylates are faster than parallel or competitive reactions of aryl chlorides.

The physicochemical properties of aqueous surfactant mixtures containing a nonionic fluorosurfactant (undecafluoro-n-pentyl-decaoxyethylene ether (C5F11EO10)) and various amounts of a cationic surfactant (decyltrimethylammonium bromide (DeTAB)) were determined by surface tension and conductivity measurements. All values of the critical micelle concentrations of the mixtures turn out to be smaller than those of both pure surfactants revealing the presence of a significant synergy for all DeTAB proportions in the mixed system. The analysis of the experimental data was performed on the basis of three different well established thermodynamic models of mixed micelle formation to determine several relevant parameters, especially the micelle composition, the interaction parameters, and the free energy of micelle formation. The results indicate that the dominant interactions between DeTAB and C5F11EO10 molecules are attractive. The main reason for this behavior could be attributed to the complexation between the polyoxyethylene chain of C5F11EO10 and the quaternary ammonium group of DeTAB giving rise to stable structures.

A novel ruthenium(II) polypyridyl complex connected covalently to a bolaamphiphile, containing amide linkages to provide rigidity via hydrogen bonding in the monolayer, has been prepared. The ruthenium(II) complexes of this ligand and of the intermediates in the synthesis were prepared by modification of the coordinated ligands, demonstrating the synthetic versatility and robustness of this family of complexes. All ruthenium complexes were characterised by electrochemical and spectroscopic techniques and were found to have similar properties to the parent complex [Ru(bipy)3]2+, and remain versatile photosensitisers, with well-defined properties, despite extensive substitution of the bipy ligand.

The enantiopure Ni(II) helicates [Ni2L1RR.Cl2] (1), [Ni2L1SS.Cl2] (1?), [Ni2L2RR.Cl2] (2), [Ni2L2SS.Cl2] (2?) were synthesized by one-pot self-assembly technique from R-(+)- or S-(?)-1,1?-binaphthyl-2,2?-diamine, with 4-methyl-2,6-diformyl phenol or 4-tert-butyl-2,6-diformyl phenol and nickel salts. This binuclear double stranded Ni(II) helicates were characterized by ESI-MS, IR and single crystal X-ray structure wherever applicable. The extensive chiroptical studies suggest that the complexes are enantiopure in nature. The chirality transfer from ligand L1RR & L2RR to Ni(II) metal centre produced DeltaDelta geometrical chirality, while their enantiomeric counterpart L1SS & L2SS produced LambdaLambda chirality in their respective complexes.These enantiopure helicates were applied as catalysts in asymmetric Michael addition of 1,3-dicarbonyl compounds with beta-nitrostyrene to produce nitroalkanes in good yield (96?98%) and ee (78?94%). (Figure presented.).

The catalytic asymmetric ring opening of meso-epoxides with aromatic amines was achieved using a new proline-based N,N?-dioxide-indium tris(triflate) complex in high yields (up to 99%) with excellent enantioselectivities (up to 99% ee) under mild conditions. The coordination ability of N,N?-dioxide 1c was investigated by X-ray and NMR analysis. A plausible seven-coordinate transition state model was proposed. The chiral N,N?-dioxides surveyed were synthesized from proline through only three conventional steps. The procedure could be run on a gram-scale without any loss of enantioselectivity. This protocol provides a highly practical and useful tool for the bulky preparation of optically pure beta-amino alcohols.
