Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C13H22BrN, you can also check out more blogs about5197-95-5

In the series of 1-pyrenylmethylamines studied in this work the relationships among structure, interaction with DNA, and murine antitumor activity were examined.Binding studies show that all of these 1-pyrenylmethylamine derivatives bind to some extent to DNA by intercalation.The presence of additional basic amine groups in the side chain enhances DNA binding due to electrostatic interactions.Those compounds containing only a single basic benzylic amine bind similarly to DNA.Only the presence of bulky side chains appears to decrease the DNA interactions in the compounds examined.Although antitumor activity is seen for (1-pyrenylmethyl)amino alcohols, useful antitumor activity in the series is limited to those congeners bearing the 2-amino-1,3-propanediol-type side chain.These derivatives bind moderately to DNA.DNA binding is a necessary but not sufficient criterion for antitumor activity in the series.In addition, the strength of DNA binding does not correlate with the antitumor activity in the group of active compounds.Three related 2-<(arylmethyl)amino>-1,3-propanediol derivatives (AMAPs) are currently in clinical trials as potential antitumor agents.

CDC7 is a serine/threonine kinase that has been shown to be required for the initiation and maintenance of DNA replication. Up-regulation of CDC7 is detected in multiple tumor cell lines, with inhibition of CDC7 resulting in cell cycle arrest. In this paper, we disclose the discovery of a potent and selective CDC7 inhibitor, XL413 (14), which was advanced into Phase 1 clinical trials. Starting from advanced lead 3, described in a preceding communication, we optimized the CDC7 potency and selectivity to demonstrate in vitro CDC7 dependent cell cycle arrest and in vivo tumor growth inhibition in a Colo-205 xenograft model.

We recently identified bis(amide) CCG-1423 (1) as a novel inhibitor of RhoA/C-mediated gene transcription that is capable of inhibiting invasion of PC-3 prostate cancer cells in a Matrigel model of metastasis. An initial structure-activity relationship study focusing on bioisosteric replacement of the amides and conformational restriction identified two compounds, 4g and 8, with improved selectivity for inhibition of RhoA/C-mediated gene transcription and attenuated cytotoxicity relative to 1. Both compounds were also capable of inhibiting cell invasion with equal efficacy to 1 but with less attendant cytotoxicity.

A small library of 17 modular and easily accessible phenol-derived chiral phosphine – phosphite ligands was evaluated in the asymmetric Rh-catalyzed hydroformylation of styrene. It was found that the stereochemical outcome of the reaction is highly dependent on the chiral phosphite moiety and the substituents on the phenolic backbone. Among the ligands studied, Taddol-based ligands of type 10 bearing bulky substituents in ortho-position to the phosphite performed best, with enantioselectivities of up to 85% ee and regioselectivities of ?98:2. High-pressure NMR of the active catalyst [HRh(P-P)(CO)2] (P-P = 10h) revealed an equatorial-apical coordination of the ligand at rhodium. Temperature dependency of the coupling constants observed during the experiment indicates equilibrium between the two equatorial-apical isomers, with the isomer in which the phosphite occupies the equatorial position being the dominant species.

High-yield syntheses of Cu(II)- and Ni(II)-templated [2]pseudorotaxane precursors (CuPRT and NiPRT, respectively) were achieved by threading bis(azide)bis(amide)-2,2-bipyridine axle into a bis(amide)tris(amine) macrocycle. Single-crystal X-ray structural analysis of CuPRT revealed complete threading of the axle fragment into the wheel cavity, where strong aromatic pi-pi stacking interactions between two parallel arene moieties of the wheel and the pyridyl unit of axle are operative in addition to metal ion templation. Attachment of a newly developed bulky stopper molecule with a terminal alkyne to CuPRT via a Cu(I)-catalyzed azide-alkyne cycloaddition reaction failed as a result of dethreading of the azide-terminated axle under the reaction conditions. However, the synthesis of a metal-free [2]rotaxane containing triazole with other functionalities in the axle was achieved in ?45% yield upon coupling between azide-terminated NiPRT and the alkyne-terminated stopper. The [2]rotaxane was characterized by mass spectrometry, 1D and 2D NMR (COSY, DOSY, and ROESY) experiments. Comparative solution-state NMR studies of the [2]rotaxane in its unprotonated and protonated states were carried out to locate the position of the wheel on the axle of the metal-free [2]rotaxane. Furthermore, a variable-temperature 1H NMR study in DMSO-d6 of [2]rotaxane supported the kinetic inertness of the interlocked structure, where the newly developed stopper prevents dethreading of the 30-membered wheel from the axle.

Application of 1941-30-6, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1941-30-6, Name is Tetrapropylammonium bromide, molecular formula is C12H28BrN. In a Article，once mentioned of 1941-30-6

We report for the first time phonon properties of [(C3H7)4N][M(N(CN)2)3] with M?Mn, Co, Ni (TPrAM), and theoretical Density Functional Theory (DFT) data for isolated TPrA+ cation obtained using harmonic and anharmonic approximation. Manganese compound undergoes one structural temperature-induced phase transition, whereas others exhibit multiple structural phase transitions in a broad temperature ranges. Temperature-dependent Raman studies let us obtain insight into mechanism of these transitions. The phase transition at about 330 K in TPrAMn involves mainly the ordering of the dca bridges coordinating Mn2+ ions and is accompanied by partial ordering of the TPrA+ cations and their shift in the cavities. However, the behavior of TPrANi is different. In particular, very large broadening of bands, attributed to vibrations of the dca and TPrA+ cations, revealed highly dynamic nature of these groups in all phases. This result indicates that observed phase transitions are associated with changing the dynamic disorder of both organic ions. Raman studies also show that all phase transformations are accompanied by slight modification in tilting of the NiN6 octahedra caused by shift of the TPrA+ ions in the cavities.
