Protein kinase CK-1 inhibitors as new potential drugs for amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease where motor neurons in cortex, brain stem, and spinal cord die progressively, resulting in muscle wasting, paralysis, and death. Currently, effective therapies for ALS are lacking; however, identification of pathological TAR DNA-binding protein 43 (TDP-43) as the hallmark lesion in sporadic ALS suggests new therapeutic targets for pharmacological intervention. Pathological TDP-43 phosphorylation appears to drive the onset and progression of ALS and may result from upregulation of the protein kinase CK-1 in affected neurons, resulting in postranslational TDP-43 modification. Consequently, brain penetrant specific CK-1 inhibitors may provide a new therapeutic strategy for treating ALS and other TDP-43 proteinopathies. Using a chemical genetic approach, we report the discovery and further optimization of a number of potent CK-1delta inhibitors. Moreover, these small heterocyclic molecules are able to prevent TDP-43 phosphorylation in cell cultures, to increase Drosophila lifespan by reduction of TDP-43 neurotoxicity, and are predicted to cross the blood-brain barrier. Thus, N-(benzothiazolyl)-2-phenyl-acetamides are valuable drug candidates for further studies and may be a new therapeutic approach for ALS and others pathologies in which TDP-43 is involved.

Discovery of potent IDO1 inhibitors derived from tryptophan using scaffold-hopping and structure-based design approaches

Indoleamine 2,3-dioxygenase 1 (IDO1) is frequently hijacked by tumors to escape the host immune response, and the enzyme is now firmly established as an attractive target for cancer immunotherapy. To identify novel IDO1 inhibitors suitable for drug development, a scaffold-hopping strategy combined with the average electrostatic potentials calculation was ultilized to design novel benzoxazolinone derivatives. Among these, compounds 7e, 7f and 9c exhibited the inhibitory potency in the low micromolar range and displayed negligible level of cytotoxicity against HeLa cells. Treatment with these three compounds promoted the proliferation of T lymphocyte and led to the dramatic decrease of regulatory T cells in the B16F1 cells and naive T cells co-culture system. Subsequent spectroscopic experiments suggested that these benzoxazolinones formed a coordinate bond with the heme iron to stabilize the complex. This study suggested that the benzoxazolinone was an interesting scaffold for discovering novel IDO1 inhibitors, and these compounds are attractive candidates for further development.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 13451-79-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13451-79-1, in my other articles.

Benzoxazolamines and Benzothiazolamines: Potent, Enantioselective Inhibitors of Leukotriene Biosynthesis with a Novel Mechanism of Action

A series of benzoxazolamine and benzothiazolamine analogs that inhibit leukotriene (LT) biosynthesis are described.The initial lead, (S)-N-(benzothiazol-2-yl)phenylalanine ethyl ester (5a), was discovered in a screening program for inhibition of Ca-ionophore-A23187-induced LTB4 release in human polymorphonuclear leukocytes (IC50 0.23 muM).Through structural modification, it was determined that hydrophobic substituents in the 5-position and replacement of the phenyl ring of phenylalanine with a cyclohexyl group greatly enhance potency.Several ester bioisosteres that retain potency and enantiomeric selectivity are described.Lead optimization culminated in (S)-N-<2-cyclohexyl-1-(2-pyridinyl)ethyl>-5-methyl-2-benzoxazolamine (43b), IC50 0.001 muM.The compounds described are not inhibitors of 5-lipoxygenase but, rather, act at the level of arachidonic acid release.

Fragment-based design of 3-aminopyridine-derived amides as potent inhibitors of human nicotinamide phosphoribosyltransferase (NAMPT)

The fragment-based identification of two novel and potent biochemical inhibitors of the nicotinamide phosphoribosyltransferase (NAMPT) enzyme is described. These compounds (51 and 63) incorporate an amide moiety derived from 3-aminopyridine, and are thus structurally distinct from other known anti-NAMPT agents. Each exhibits potent inhibition of NAMPT biochemical activity (IC 50 = 19 and 15 nM, respectively) as well as robust antiproliferative properties in A2780 cell culture experiments (IC50 = 121 and 99 nM, respectively). However, additional biological studies indicate that only inhibitor 51 exerts its A2780 cell culture effects via a NAMPT-mediated mechanism. The crystal structures of both 51 and 63 in complex with NAMPT are also independently described.

Inhibitory effects of Japanese horseradish (Wasabia japonica) on the formation and genotoxicity of a potent carcinogen, acrylamide

BACKGROUND: The formation of acrylamide (AA) in cooked foods has raised human health concerns. AA is metabolized by cytochrome P450 2E1 (CYP2E1) to glycidamide (GA), which forms DNA adducts. This study examined the inhibitory effects of wasabi (Japanese horseradish, Wasabia japonica) roots and leaves as well as their active component, allyl isothiocyanate (AIT), on the formation and genotoxicity of AA. RESULTS: AA formation (51.8 ¡À 4.2 mug kg?1) was inhibited with ?2 mg mL?1 of AIT. Wasabi roots also inhibited AA formation (?90% reduction), but wasabi leaves were not effective at 2 mg mL?1. Wasabi roots and leaves decreased the number of cells with micronuclei by approximately 33 and 24% respectively compared with the AA treatment group. Moreover, wasabi roots and leaves (100 mg kg?1 body weight (BW) day?1 for each) decreased AA (100 mg kg?1 BW day?1)-induced DNA damage. The AA-induced CYP2E1 activity was decreased by 39 and 26% with wasabi roots and leaves respectively. Further, the activity of glutathione S-transferase, which catalyzes the detoxification of AA via glutathione conjugation, increased by 54 and 33% with wasabi roots and leaves respectively. CONCLUSION: These results indicate that wasabi roots and leaves are effective ingredients for inhibiting the formation and genotoxicity of AA.

Room-temperature cobalt-catalyzed arylation of aromatic acids: overriding the ortho-selectivity via the oxidative assembly of carboxylate and aryl titanate reagents using oxygen

A room temperature phosphine or NHC ligand-free cobalt-catalyzed arylation of (hetero)aromatic acids has been developed. It involves an oxidative cross-coupling between carboxylate and aryl titanate reagents using oxygen as an oxidant, and the arylation at the position ortho, meta and para to the carboxylic acid group could all be achieved. As application, various (hetero)aromatic acids including xenalipin, tafamidis and the key intermediate for a cardioprotective compound have been efficiently synthesized.
