N-phenyl-4-pyrazolo[1,5-6]pyridazin-3-ylpyrimidin-2-amines as potent and selective inhibitors of glycogen synthase kinase 3 with good cellular efficacy

Glycogen synthase kinase 3 regulates glycogen synthase, the rate-determining enzyme for glycogen synthesis. Liver and muscle glycogen synthesis is defective in type 2 diabetics, resulting in elevated plasma glucose levels. Inhibition of GSK-3 could potentially be an effective method to control plasma glucose levels in type 2 diabetics. Structure-activity studies on a N-phenyl-4-pyrazolo[1,5-b]pyridazin-3-ylpyrimidin-2-amine series have led to the identification of potent and selective compounds with good cellular efficacy. Molecular modeling studies have given insights into the mode of binding of these inhibitors. Since the initial leads were also potent inhibitors of CDK-2/CDK-4, an extensive SAR was performed at various positions of the pyrazolo[1,5-b] pyridazin core to afford potent GSK-3 inhibitors that were highly selective over CDK-2. In addition, these inhibitors also exhibited very good cell efficacy and functional response. A representative example was shown to have good oral exposure levels, extending their utility in an in vivo setting. These inhibitors provide a viable lead series in the discovery of new therapies for the treatment of type 2 diabetes.

Process for dyeing mixed anionic/cationic polyamide substrates with a specific type of vinyl sulfone dye

The invention is a process for dyeing polyamide substrates comprising anionic and cationic fibers in multi-colored patterns. Cross-staining or dyeing of the cationic fibers by the anionic-dyeable nylon colorant is avoided. The anionic dyeable fiber portion is dyed with a fiber-reactive vinyl sulfone dye having one or more sulfonic acid substituents and one or more vinyl sulfone groups with the proviso that the sum of the number of sulfonic acid and vinyl sulfone substituents is at least three. The dyeing process is conducted at a pH of about 2 to about 4. Optionally the cationic portion of the substrate may be dyed with a basic dye in admixture with the vinyl sulfone dye.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C5H5ClN2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1121-79-5, Name is 3-Chloro-6-methylpyridazine, molecular formula is C5H5ClN2

Identification, synthesis, and biological evaluation of 6-[(6 R)-2-(4-fluorophenyl)-6-(hydroxymethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a ]pyrimidin-3-yl]-2-(2-methylphenyl)pyridazin-3(2 H)-one (AS1940477), a potent p38 MAP kinase inhibitor

Several p38 MAPK inhibitors have been shown to effectively block the production of cytokines such as IL-1beta, TNFalpha, and IL-6. Inhibitors of p38 MAP kinase therefore have significant therapeutic potential for the treatment of autoimmune disease. Compound 2a was identified as a potent TNFalpha production inhibitor in vitro but suffered from poor oral bioavailability. Structural modification of 2a led to the discovery of tetrahydropyrazolopyrimidine derivatives, exemplified by compound 3, with an improved pharmacokinetic profile. We found that blocking metabolism at the methyl group of the amine and constructing the tetrahydropyrimidine core were important to obtaining compounds with good biological profiles and oral bioavailability. Pursuing the structure-activity relationships of this series led to the discovery of AS1940477 (3f), with excellent cellular activity and a favorable pharmacokinetic profile. This compound represents a highly potent inhibitor of p38 MAP kinase with regard to in vivo activity in an adjuvant-induced arthritis model.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C5H5ClN2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1121-79-5, in my other articles.
