Synthesis and identification of [1,3,5]triazine-pyridine biheteroaryl as a novel series of potent cyclin-dependent kinase inhibitors

On the basis of previous studies, we identified pyrazine-pyridine A as a potent vascular endothelial growth factor inhibitor and pyrimidine-pyridine B as a moderately potent cyclin dependent kinase (CDK) inhibitor. A proposed combination of CGP-60474 and compound B led to the discovery of [1,3,5]triazine-pyridine as a new series of potent CDK inhibitors. Palladium-catalyzed C-C bond formation reactions, particularly the Negishi coupling reaction, were used to assemble various triazine-heteroaryl analogues effectively. Among them, compound 20 displayed high inhibitory potency at CDKl (IC50 = 0.021 muM), CDK2, and CDK5 and submicromolar potency at CDK4, CDK6, and CDK7. Compound 20 also displayed high potency at GSK-3beta. It demonstrated potent antiproliferative activity on various tumor cell lines, including HeLa, HCT-116, U937, and A375. When 20 was administered intraperitoneally at 150 and 125 mg/kg to nude mice bearing human A375 xenografts, the compound produced a significant survival increase. Molecular docking studies were conducted in an attempt to enhance the understanding of the observed structure-activity relationship.

AlCl3-DMA reagent in the regioselective solvent free Friedel-Crafts acylation reaction of benzodioxin derivatives

A general method for the regioselective solvent free Friedel-Crafts acylation of 2-substituted-1,4-benzodioxin derivatives in excellent yields employing the AlCl3-DMA reagent with acyl halides or anhydrides as acylating agents is described. The acylation of 2-substituted-1,4-benzodioxin derivatives provides the 6-acyl compound as the major product. However, the saturated analogs affords the 7-acyl regioisomer as the main compound.

Chalcone?benzoxaborole hybrids as novel anticancer agents

In this study, we report the synthesis of a series of chalcone?benzoxaborole hybrid molecules and the evaluation of their anticancer activity. Their anticancer potency and toxicity were tested on three human cancer cell lines and two normal cell lines. The 4-fluoro compound 15 was found to be the most potent compound with an IC50value of 1.4 muM on SKOV3 cells. The 4-iodo compound 18 and 3-methyloxy-4-amino compound 47 showed good potency on SKOV3 cells while exhibiting low toxicity on normal cells. This work extended the application of benzoxaboroles to the field of anticancer research.

Structural modifications to tetrahydropyridine-3-carboxylate esters en route to the discovery of M5-preferring muscarinic receptor orthosteric antagonists

The M5 muscarinic acetylcholine receptor is suggested to be a potential pharmacotherapeutic target for the treatment of drug abuse. We describe herein the discovery of a series of M5-preferring orthosteric antagonists based on the scaffold of 1,2,5,6-tetrahydropyridine-3- carboxylic acid. Compound 56, the most selective compound in this series, possesses an 11-fold selectivity for the M5 over M1 receptor and shows little activity at M2-M4. This compound, although exhibiting modest affinity (Ki = 2.24 muM) for the [3H]N-methylscopolamine binding site on the M5 receptor, is potent (IC50 = 0.45 nM) in inhibiting oxotremorine-evoked [3H]DA release from rat striatal slices. Further, a homology model of human M5 receptor based on the crystal structure of the rat M3 receptor was constructed, and docking studies of compounds 28 and 56 were performed in an attempt to understand the possible binding mode of these novel analogues to the receptor.

PYRANOQUINAZOLINE DERIVATIVES AND NAPHTHOPYRAN DERIVATIVES

[Problem] A problem is presented in that conventional photochromic compounds cannot be considered adequate in terms of the colorizing/decolorizing rate and durability, and the production process therefore has many steps. The present invention provides an industrially applicable photochromic compound that has both a rapid colorizing/decolorizing reaction and high durability and can also be synthesized at a low cost. [Solution] This compound is characterized in that etheric oxygen atoms are bonded to the carbon atoms at position 1 of a pyranoquinazoline (8H-pyrano[3,2-f]quinazoline) skeleton and position 10 of a naphthopyran (3H-naphtho[2,1-b]pyran) skeleton, said compound having photochromic properties and being a photochromic compound that has both a rapid colorizing/decolorizing reaction and high durability. Also provided is an industrially applicable photochromic compound that can be synthesized at a low cost.
