Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 86329-79-5, Name is Cefodizime Disodium, category: thiazole.

Cefodizime, a new cephem antibiotic, was intravenously injected to mice with systemic or urinary tract infection by Escherichia coli and those with respiratory infection by Streptococcus pneumoniae, and the time courses of the plasma and tissue cefodizime levels were determined and compared with those in healthy mice (control group). In mice with systemic infection, the drug level in the plasma, liver, kidneys and lung changed on the basis of the two-compartment model. In this group, disappearance of the drug from plasma and tissues was obviously delayed and decrease in elimination constant (K(E)) and increase in the apparent volume of distribution (V2) were noted as compared with the control group. In the group with respiratory infection, T 1/2 (beta) and AUC for the hepatic drug level and T 1/2 (beta) for the renal drug level increased but in the other organs there was no great difference from the control group. In the urinary tract infection group, T 1/2 (beta) and AUC in the kidneys (infected site) and liver that mainly participate in elimination of cefodizime considerably increased differently from the control group. Changes of the distribution volume seemed to correspond with a physiological change of increase in body water content in the peripheral tissues (muscle, etc.) of the systemic infection group and in the liver, kidneys, etc. of the urinary tract infection group. Regarding the protein binding ratio, the urinary tract infection group showed a significant decrease as compared with the control group, but no distinct difference was noted in systemic and respiratory infections.

Application of 38205-60-6, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.38205-60-6, Name is 1-(2,4-Dimethylthiazol-5-yl)ethanone, molecular formula is C7H9NOS. In a patent, introducing its new discovery.

Following the identification through virtual screening of 4-(2,4-dimethyl-thiazol-5-yl)pyrimidin-2-ylamines as moderately potent inhibitors of cyclin-dependent kinase-2 (CDK2), a CDK inhibitor analogue program was initiated. The first aims were to optimize potency and to evaluate the cellular mode of action of lead candidate molecules. Here the synthetic chemistry, the structure-guided design approach, and the structure-activity relationships (SARs) that led to the discovery of 2-anilino-4-(thiazol-5-yl)pyrimidine ATP-antagonistic CDK2 inhibitors, many with very low nM Kis against CDK2, are reported. Furthermore, X-ray crystal structures of four representative analogues from our chemical series in complex with CDK2 are presented, and these structures are used to rationalize the observed biochemical SARs. Finally results are reported that show, using the most potent CDK2 inhibitor compound from the current series, that the observed antiproliferative and proapoptotic effects are consistent with cellular CDK2 and CDK9 inhibition.

Thrombin inhibitors are potentially useful in medicine for their anticoagulant and antithrombotic effects. We synthesized and evaluated diverse heterocycle-activated ketones based on the D-Phe-Pro-Arg, and related thrombin active-site recognition motifs, as candidate inhibitors. The peptide-based alpha-ketoheterocycles were typically prepared by either an imidate or a Weinreb amide route (Schemes 1 and 2), the latter of which proved to be more general. Test compounds were generally assayed for inhibition of human alpha-thrombin and bovine trypsin. From a structure-based design standpoint, the heterocycle allows one to explore and adjust interactions within the S1? subsite of thrombin. The preferred alpha-ketoheterocycle is a pi-rich 2-substituted azole with at least two heteroatoms proximal to the carbon bearing the keto group, and a preferred thrombin inhibitor is 2-ketobenzothiazole 3, with a potent Ki value of 0.2 nM and ca. 15-fold selectivity over trypsin. 2-Ketobenzothiazole 13 exhibited exceedingly potent thrombin inhibition (Ki = 0.000 65 nM; slow tight binding). Several alpha-ketoheterocycles had thrombin Ki values in the range 0.1-400 nM. The “Arg” unit in the alpha-ketoheterocycles can be sensitive to stereomutation under mildy basic conditions. For example, 2-ketothiazoles 4 and 59 readily epimerize at pH 7.4, although they are fairly stable stereochemically at pH 3-4; thus, suitable conditions had to be selected for the enzymatic assays. Lead D-Phe-Pro-Arg 2-benzothiazoles 3, 4, and 68 displayed good selectivity for thrombin over other key coagulation enzymes (e.g., factor Xa, plasmin, protein Ca, uPA, tPA, and streptokinase); however, their selectivity for thrombin over trypsin was modest (<25-fold). Compounds 3, 4, and 68 exhibited potent in vitro antithrombotic activity as measured by inhibition of gel-filtered platelet aggregation induced by alpha-thrombin (IC50 = 30-40 nM). They also proved to be potent anticoagulant/ antithrombotic agents in vivo on intravenous administration, as determined in the canine arteriovenous shunt (ED50 = 0.45-0.65 mg/kg) and the rabbit deep vein thrombosis (ED50 = 0.1-0.4 mg/kg) models. Intravenous administration of 3, and several analogues, to guinea pigs caused hypotension and electrocardiogram abnormalities. Such cardiovascular side effects were also observed with some nonguanidine inhibitors and inhibitors having recognition motifs other than D-Phe-Pro-Arg. 2-Benzothiazolecarboxylates 4 and 68 exhibited significantly diminished cardiovascular side effects, and benzothiazolecarboxylic acid 4 had the best profile with respect to therapeutic index. The X-ray crystal structures of the ternary complexes 3-thrombin-hirugen and 4-thrombin-hirugen depict novel interactions in the S1? region, with the benzothiazole ring forming a hydrogen bond with His-57 and an aromatic stacking interaction with Trp-60D of thrombin's insertion loop. The benzothiazole ring of 3 displaces the Lys-60F side chain into a U-shaped gauche conformation, whereas the benzothiazole carboxylate of 4 forms a salt bridge with the side chain of Lys-60F such that it adopts an extended anti conformation. Since 3 has a 10-fold greater affinity for thrombin than does 4, any increase in binding energy resulting from this salt bridge is apparently offset by perturbations across the enzyme (viz. Figure 4). The increased affinity and selectivity of 2-ketobenzothiazole inhibitors, such as 3, may be primarily due to the aromatic stacking interaction with Trp-60D. However, energy contour calculations with the computer program GRID also indicate a favorable interaction between the benzothiazole sulfur atom and a hydrophobic patch on the surface of thrombin.

Nuclear magnetic resonance (NMR) spectroscopy has been established as a potent method for the determination of foldamer structures in solution. However, the NMR techniques could be limited by averaging, so additional experimental techniques are often needed to fully endorse the folding properties of a sequence. We have recently demonstrated that oligo-gamma-peptides composed of 4-amino(methyl)-1,3-thiazole-5-carboxylic acids (ATCs) adopt an original helical fold stabilized by hydrogen bonds forming C9 pseudocycles. The main objective of the present work is to reinvestigate the folding of ATC oligomer 1 in order to identify reliable FT-IR and NMR structural markers that are of value for tracking the degree of organization of ATC-based peptides.

In this paper, we present the structure-based design, synthesis and biological activity of N-pyrazole, N?-thiazole-ureas as potent inhibitors of p38alpha mitogen-activated protein kinase (p38alpha MAPK). Guided by complex crystal structures, we employed the initially identified N-aryl, N?-thiazole urea scaffold and introduced key structural elements that allowed the formation of novel hydrogen bonding interactions within the allosteric site of p38alpha, resulting in potent type III inhibitors. [4-(3-tert-Butyl-5-{[(1,3-thiazol-2-ylamino)carbonyl]amino}-1H-pyrazol-1-yl) -phenyl]acetic acid 18c was found to be the most potent compound within this series and inhibited p38alpha activity with an IC50 of 135 ± 21 nM. Its closest analog, ethyl [4-(3-tert-butyl-5-{[(1,3-thiazol-2-ylamino) carbonyl]amino}-1H-pyrazol-1-yl)phenyl]acetate 18b, effectively inhibited p38alpha mediated phosphorylation of the mitogen activated protein kinase activated protein kinase 2 (MK2) in HeLa cells.
