A simple and efficient method for the direct synthesis of nitriles from aldehydes using ammonium acetate as the nitrogen source has been developed. The reactions were performed with iodine as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant under mild conditions. A variety of aromatic, heteroaromatic, aliphatic and allylic aldehydes could be converted into their corresponding nitriles in good to excellent yields.

We have studied the subtleties of fragment docking and binding using data generated in a Pim-1 kinase inhibitor program. Crystallographic and docking data analyses have been undertaken using inhibitor complexes derived from an in-house surface plasmon resonance (SPR) fragment screen, a virtual needle screen, and a de novo designed fragment inhibitor hybrid. These investigations highlight that fragments that do not fill their binding pocket can exhibit promiscuous hydrophobic interactions due to the lack of steric constraints imposed on them by the boundaries of said pocket. As a result, docking modes that disagree with an observed crystal structure but maintain key crystallographically observed hydrogen bonds still have potential value in ligand design and optimization. This observation runs counter to the lore in fragment-based drug design that all fragment elaboration must be based on the parent crystal structure alone.

Regiocontrolled nitration of 4-quinolone, the highly privileged scaffold, has been developed at ambient conditions. The nitro group can selectively be introduced at diverse positions simply by tuning the reactivity of the moiety. Discrimination is being achieved through the selective functionalization of the free N-H group. The functional group has been screened theoretically with the help of Fukui function and local softness calculation. Theoretical predictions are synchronized well with the experimental findings. Finally, this nitration technique allows quick access to the structurally diverse 4-quinolones.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10242-12-3 is helpful to your research. Reference of 10242-12-3

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 1-Oxo-1,3-dihydroisobenzofuran-5-carbonitrile, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 82104-74-3, name is 1-Oxo-1,3-dihydroisobenzofuran-5-carbonitrile.

The synthesis and biological activity of two series of nonclassical thymidylate synthase (TS) inhibitors are described. The first is a series of 10-propargyl-5.8-dideazafolic acid derivatives (10a-j) and the second is a series of the analogous 2-desamino derivatives (13a-c,k), both bearing a more lipophilic substituent on the phenyl ring than the CO-glutamate of classical antifolates. Compounds 10a-j were prepared in a straightforward manner, generally by treatment of N-[6-(bromomethyl)-3,4-dihydro-4-oxo-2-quinazolinyl]-2,2- dimethylpropanamide (6) with various phenyl-substituted N-propargylanilines (8), followed by deprotection. Compounds 13a-c,k were prepared similarly from [6-(bromomethyl)-4-oxo-3(4H)-quinazolinyl]methyl 2,2-dimethylpropanoate (11). The compounds were tested for inhibition of purified L1210 TS and for inhibition of L1210 cell growth in vitro. Several of these nonclassical analogues approached the TS inhibitory potency of 10-propargyl-5,8-dideazafolic acid (1, CB3717), a glutamate-containing TS inhibitor. 2-Amino target compounds 10a-j were generally potent inhibitors of L1210 TS, with IC50s within the range of 0.51-11.5 muM, compared to 0.05 muM for 1. The order of potency for phenyl substitution at the 4-position in this series was the following: COCF3?NO2?CONH2?COCH3>SO2NMe2>SO2NMe2>CN>>OCF3?F. The 2-desamino target compounds 13a-c,k also exhibited significant, although diminished, TS inhibition. Both series were growth inhibitory to cells in tissue culture and this inhibition could be reversed by thymidine alone, indicating that the primary targt was TS. None of the compounds was a potent inhibitor of dihydrofolate reductase. These studies indicate that the presence of the glutamate moiety in folate analogues is not an absolute requirement for potent inhibition of TS.

Reference of 1552-42-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1552-42-7, Name is Crystal violet lactone, molecular formula is C26H29N3O2. In a Article，once mentioned of 1552-42-7

Multiphoton absorption (MPA) is an enabling technology for many applications. However, due to the low probability of MPA processes, their accurate characterization remains a challenge. Here we introduce a new technique, two-beam constant emission intensity (2-BCEIn) spectroscopy, that offers substantial advantages over other existing methods that use the generation of optical emission for the characterization of absorptive nonlinearities. We use 2-BCEIn to study nonlinear absorption in solutions of crystal violet lactone (CVL) over a range of excitation wavelengths in which the dominant nonlinear absorption process transitions from two-photon absorption (750 nm) to three-photon absorption (830 nm). At an excitation wavelength of 800 nm, both two-photon absorption and three-photon absorption contribute substantially to the nonlinear fluorescence excitation (NFE) signal, although the dynamic range of the NFE data is not sufficient to quantify the contributions of each process. 2-BCEIn spectroscopy enables the direct measurement of the local exponent at each emission intensity. 2-BCEIn measurements made at several different emission intensities demonstrate unambiguously that the nonlinear excitation of CVL at 800 nm cannot be described solely as the sum of a two-photon process and a three-photon process. A kinetic model that includes intrapulse excited-state absorption reproduces the features of the 2-BCEIn measurements and enables the determination of the ratio of the three-photon absorption cross section to the two-photon absorption cross section. Such information cannot easily be extracted from conventional NFE measurements. These results demonstrate the power and versatility of two-beam action spectroscopies for elucidating the complex photophysics of multiphoton absorption processes.

The search for Insulin Sensitivity Enhancer (ISE) compounds, for potential use in the treatment of Type II diabetes, has led to the synthesis of compounds that contain a benzofuran spacer between an aryloyl substituent and a 2,4-thiazolidinedione pharmacophore. Sequential combination of haloacetyl aryl substrates with 5-formylsalicylaldehyde gave the desired 2-aryloyl-5-formylbenzofuran intermediates. A related class of compounds, those with a methylene tether between the aromatic moiety and the benzofuran spacer, were also prepared through this strategy.
