Polo-like kinase-2 (Plk-2) is a potential therapeutic target for Parkinson’s disease and this Letter describes the SAR of a series of dihydropteridinone based Plk-2 inhibitors. By optimizing both the N-8 substituent and the biaryl region of the inhibitors we obtained single digit nanomolar compounds such as 37 with excellent selectivity for Plk-2 over Plk-1. When dosed orally in rats, compound 37 demonstrated a 41-45% reduction of pS129-alpha-synuclein levels in the cerebral cortex.

An intriguing conversion of arylglyoxal, cyclic dicarbonyl compounds and phenols to diverse furan analogues under FeCl3 or MeSO3H catalysis is reported. Utilizing this synthetic protocol, a variety of furan analogues could be easily obtained in moderate to good yields with different substituted patterns by varying the reaction medium. Atom-economical characteristics and mild conditions of this method are in accord with the concept of modern green chemistry.

Electric Literature of 17347-61-4, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 17347-61-4, Name is 2,2-Dimethylsuccinicanhydride,introducing its new discovery.

The paper reports on the synthesis of a series of acyl derivatives of betulin and dihydroquinopimaric acid and the study of their antiviral activity against influenza A virus (H7N1), herpes simplex virus type 1 (HSV-1), ECHO 6, and HIV-1 in comparison with the activity of the previously obtained acylates and original terpenoids. It has been demonstrated that acylated betulin and betulinic acid show no advantage in inhibiting the reproduction of all the tested viruses compared with the betulic acid, while structural modifications at positions C3 and C28 of the triterpene core led to some changes in the spectrum of antiviral activity. Modification of dihydroquinopimaric acid at position C4 increased the activity of this compound against influenza virus A (H7N1).

Phosphodiesterase 4 catalyzes the hydrolysis of cyclic AMP and is a target for the development of anti-inflammatory agents. We have designed and synthesized a series of phenyl alkyl ketones as PDE4 inhibitors. Among them, 13 compounds were identified as having submicromolar IC50 values. The most potent compounds have IC50 values of in the mid- to low-nanomolar range. Compound 5v also showed preference for PDE4 with selectivity of >2000-fold over PDE7, PDE9, PDE2, and PDE5. Docking of 5v, 5zf, and 5za into the binding pocket of the PDE4 catalytic domain revealed a similar binding profile to PDE4 with rolipram except that the fluorine atoms of the difluoromethyl groups of 5v, 5za, and 5zf are within a reasonable range for hydrogen bond formation with the amide hydrogen of Thr 333 and the long alkyl chain bears additional van der Waals interactions with His 160, Asp 318, and Tyr 159.

We report structure-guided modifications of the benzyloxy substituent of the Insulin-like Growth Factor-1 Receptor (IGF-1R) inhibitor NVP-AEW541. This chemical group has been shown to confer selectivity against other protein kinases but at the expense of a metabolism liability. X-ray crystallography has revealed that the benzyloxy moiety interacts with a lysine cation of the IGF-1R kinase domain via its ether function and its aromatic pi-system and is nicely embedded in an induced hydrophobic pocket. We show that 1,4-diethers displaying an adequate hydrophobic and constrained shape are advantageous benzyloxy replacements. A single digit nanomolar inhibitor (compound 20, IC50 = 8.9 nM) was identified following this approach.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: Tetrahydrofurans, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 453-20-3, Name is 3-Hydroxytetrahydrofuran, molecular formula is C4H8O2

UV irradiation of bis(cis-1,2-dicyano-1,2-ethylenedithiolate)zinc bis(tetrabutylammonium) in aqueous tetrahydrofuran (THF) or 2,5-dihydrofuran (2,5-DHF) leads to the semiconductor n-ZnS which photocatalyses an efficient H2 evolution (Phi300nm =/>0.1) coupled to a chemoselective dehydrodimerization of the cyclic ether.The reacion does not occur in pure water nor in dry ethers. n-ZnS, which immediately photocorrodes in pure water, becames very stable in the presence of 2,5-DHF. 2,3-DHF and six-membered ethers do not dehydrodimerize or prevent photocorrosion.The H2-evolution rate increases linearity with light intensity and does not change as a function of temperature (20-50 deg C) or pH (4-10).In the case of 2,5-DHF, the previously unknown 2,2′-, 2,3′, and 3,3′-dehydrodimers are formed in the ratio of 1:2:1, respectively, on analytical and preparative scales.With THF, the reaction proceeds regioselectively with the exclusive formation of the 2,2′-dihydrodimer.A complete material balance shows that no water is consumed although the initial gas phase contains more than 90percent D2 when D2O is used.The latter value decreases with increasing turnover and is accompained by the formation of HD and H2.These results are compatible with the reduction of water to hydrogen by conduction band electrons.The dehydrodimers are produced by dimerization of the corresponding radicals formed most likely by hole oxidation of the cyclic ether with subsequent deprotonation.Comparison with reactions of OH<*> generated in homogeneous solution reveals a higher selectivity for the catalytic ZnS system.
