In a Article£¬once mentioned of 2081-44-9, Application In Synthesis of Tetrahydro-2H-pyran-4-ol

Heat shock protein 90 (Hsp90) is a potential target for oncology therapeutics. Some inhibitors have shown antitumor effects in clinical trials, spurring the discovery of small molecule Hsp90 inhibitors. Here, we describe the structural optimization studies of a hit compound, tetrahydropyrido[4,3-d]pyrimidine-based Hsp90 inhibitor 15, which exhibits inhibitory activity against Hsp90. A series of analogues were synthesized, and their structure-activity and structure-property relationships were analyzed. These explorations led to the discovery of compound 73, which exhibited potent in vitro activities, good physicochemical properties, favorable ADME properties, and a potent antitumor effect in an HCT116 xenograft model. Furthermore, 73 exhibited no ocular toxicity in a rat retinal damage model, suggesting it is a relatively safe Hsp90 inhibitor. As a promising antitumor agent, 73 was progressed for further preclinical evaluation.

In a patnet, once mentioned the new application about 499-40-1, Computed Properties of C12H22O11

The syntheses and characterization of a series of dinuclear mu-oxalato copper(II) complexes of the general type [(NN)1 or 2Cu(C2O4)Cu(NN)1 or 2]2+, where NN=didentate dpyam (di-2-pyridylamine) ligand, are described. The crystal structures of three representative complexes have been determined. The dinuclear-oxalate bridged compounds [Cu(dpyam) 4(C2O4)](ClO4)2(H 2O)3 (1) and [Cu2(dpyam)4(C 2O4)](BF4)2(H2O) 3 (2) crystallize in the non-centrosymmetric triclinic space group P1 which are isomorphous and isostructural. The compound [Cu 2(dpyam)2(C2O4)(NO3) 2((CH3)2SO)2] (3) crystallizes in the centrosymmetric monoclinic space group P1 with all Cu-oxalate contacts in the equatorial plane. All three complexes contain six-coordinate copper centres bridged by planar bis-didentate oxalate groups from the equatorial position of one chromophore to the equatorial position of the other one. Both chromophores in 1 and 2 exhibit the compressed octahedral Cu(II) geometry, while 3 displays an elongated octahedral Cu(II) environment. The IR, ligand field and EPR measurements are in agreement with the structures found. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a very weak ferromagnetic interaction between the Cu(II) atoms for compound 1 and 2, with a singlet-triplet energy gap (J) of 2.42 and 3.38 cm-1, for compounds 1 and 2, respectively. Compound 3 has a strong antiferromagnetic interaction with a J of -305.1 cm-1, in agreement with coplanarity of the magnetic orbitals.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Patent£¬once mentioned of 14215-68-0, Formula: C8H15NO6

The present invention relates to a method for preparing a sialic acid derivative, wherein the method is characterized in that a process of using N-acetyl-D-glucosamine to prepare CMP-M-acetylneuraminic acid and a process of combining sialic acid with galactose or a galactose derivative to prepare a sialic acid (neuraminic acid) derivative are performed together in one reactor. According to the present invention, a high-priced cytidine 5′-monophosphoric acid (CMP) can be recycled in a reaction container, thereby reducing the amount of cytidine 5′-monophosphoric acid (CMP) introduced into the reaction, producing a sialic acid derivative using low-priced N-acetyl-D-glucosamine and pyruvic acid as substrates, and producing the sialic acid derivative at higher efficiency.

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.Formula: C8H15NO6, you can also check out more blogs about14215-68-0

Inexpensive and readily available sulfonic acids, p-toluenesulfonic acid, and sulfuric acid are versatile and efficient catalysts for the peracetylation of a broad spectrum of carbohydrate substrates in good yield and in a practical time frame. Three appealing features in sulfonic acid-catalyzed acetylation of free sugars were explored including (1) suppression of furanosyl acetate formation for d-galactose and l-fucose; (2) high yielding chemoselective acetylation of sialic acid under appropriate conditions; and (3) peracetylation of amino sugars with different amino protecting functions. Simple one-pot two step acetylation-thioglycosidation methods for the expeditious synthesis of p-tolyl per-O-acetyl thioglycosides were also delineated.

The 7-nitrobenz-2,1,3-oxadiazole (NBD) unit is a highly useful fluorescent tag with wide application in biology. Installation of the NBD group typically proceeds via the SNAr reaction between an amine and an NBD halide. Herein, we demonstrate that NBD-F 1 results in significantly higher yields than NBD-Cl 2, and that triethylamine in dimethylformamide at 23 C overnight is a broadly applicable set of conditions for this reaction. In particular, the highly useful fluorescent carbohydrate 2-NBD-glucosamine (2-NBDG, 3) can now be prepared in 75% yield with NBD-F as compared to 12% with NBD-Cl.

Synthesis, biological testing, structure-activity relationships (SARs), and selectivity of novel disubstituted dibenzosuberone derivatives as p38 MAP kinase inhibitors are described. Hydrophilic moieties were introduced at the 7-, 8-, and 9-position of the 2-phenylamino-dibenzosuberones, improving physicochemical properties as well as potency. Extremely potent inhibitors were obtained, with half-maximal inhibitory concentration (IC50) values in the low nM range in a whole blood assay measuring the inhibition of cytokine release. The high potency of the target compounds together with the outstanding selectivity of this novel class of compounds toward p38 mitogen activated protein (MAP) kinase as compared to other kinases indicate them to be most applicable as tools in pharmacological research and eventually they may foster a new generation of anti-inflammatory drugs.
