The glycogen synthase kinase 3 (GSK-3) is implicated in multiple cellular processes and has been linked to the pathogenesis of Alzheimer’s disease (AD). In the course of our research topic we synthesized a library of potent GSK-3 inhibitors. We utilized the urea scaffold present in the potent and highly selective GSK-3 inhibitor AR-A014418 (AstraZeneca). This moiety suits both (a) a convergent approach utilizing readily accessible building blocks and (b) a divergent approach based on a microwave heating assisted Suzuki coupling. We established a chromatography-free purification method to generate products with sufficient purity for the biological assays. The structure-activity relationship of the library provided the rationale for the synthesis of the benzothiazolylurea 66 (IC50 = 140 nM) and the pyridylurea 62 (IC 50 = 98 nM), which displayed two to threefold enhanced activity versus the reference compound 18 (AR-A014418: IC50 = 330 nM) in our assays.

Synthetic Route of 5331-91-9, 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.5331-91-9, Name is 5-Chlorobenzo[d]thiazole-2(3H)-thione, molecular formula is C7H4ClNS2. In a patent, introducing its new discovery.

CSF diagnostics has proved to be a formidable testing ground for N-glycoproteomic analysis of neurological diseases. To characterize specific N-glycan profiles of CSF in early and advanced phases of Alzheimer?s disease, as well as in lysosomal storage disorders such as Tay-Sachs disease, we set up in our lab a robust and feasible protocol by coupling bioanalytical methods and mass spectrometry analysis. Starting from a few microliters of CSF, after protein denaturation, reduction, and alkylation, N-glycans are released from glycoproteins using the peptide-N-glycosidase F (PNGase F) and purified. The analysis of permethylated N-glycans by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and MALDI-TOF MS/MS allowed us to identify specific glyco-structures and also to distinguish between isobaric N-glycans.

Pyridine carboxamide-based inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified and optimized to a variety of topologically related scaffolds. In particular, the 2-methyl nicotinic acid scaffold was developed into inhibitors with improved biochemical (IC50-GT1b = 0.014 muM) and cell-based HCV replicon potency (EC50-GT1b = 0.7 muM). Biophysical and biochemical characterization identified this novel series of compounds as palm site binders to HCV polymerase.

A series of 1, 5-benzothiazepines were synthesized using disulfides and alpha, beta-unsaturated carbonyl or nitrile compounds as reaction substrates. After reductive cleavage of the S-S bond of disulfides, the resulting thiols were reacted with alpha,beta-unsaturated carbonyl or nitrile compounds to generated seven-membered heterocyclic compounds. In the presence of ammonium thioglycolate, the Michael reaction occurred between disulfides (1) and 4-methyl-3-penten-2-one to give 2, 2, 4-trymethyl-3H-1, 5-benzothiazepine derivatives in good yields. When ethyl acrylate or acrylonitrile was used as the Michael acceptor, 90-99% of (2-amino- phenylsulfanyl)propionitriles (3) and/or 92-99% of (2-amino-phenylsulfanyl) propionic acid ethyl esters (4) were produced. Subsequently, the 1, 5-benzothiazepine compounds 5 and 6 were obtained due to the cyclization reaction. The Japan Institute of Heterocyclic Chemistry.
