Synthesis of analogues of the 2,3,6-triazaphenothiazine ring system

Treatment of 2,3-dichloroquinoxalines with 2-amino-6-picoline-3-thiol gave a mixture of 2,3-bis(2-amino-6-picolinyl-3-thio)quinoxalines (16, R = H, Cl) and 2,3-bis (N,N-dimethylamino)quinoxalines (15, R = H, Cl) separated by fractional crystallization. A similar reaction of 3-amino-6-methoxypyridine-2(1H)-thione (9) with 4,5-dichloropyridazin-3(2H)-one (21) gave 4-chloro-5-(3-amino-6-methoxypyridyl-2-thio)pyridazin-3(2H)-one (22). Concentrated hydrochloric acid-catalysed cyclization of 22 gave the nonrearranged 7-methoxy-2,3,6-triazaphenothiazin-1(2H)-one. The action of compound 22 in refluxing glacial acetic acid gave, on the other hand, 7-methoxy-2,3,6-triazaphenothiazin-4(3H)-one via a Smiles rearrangement. These cyclized compounds are the first known derivatives of the new 2,3,6-triazaphenothiazine ring system.

Pyrrolo[3,2-b ]quinoxaline derivatives as types I1/2 and II Eph tyrosine kinase inhibitors: Structure-based design, synthesis, and in vivo validation

The X-ray crystal structures of the catalytic domain of the EphA3 tyrosine kinase in complex with two type I inhibitors previously discovered in silico (compounds A and B) were used to design type I1/2 and II inhibitors. Chemical synthesis of about 25 derivatives culminated in the discovery of compounds 11d (type I1/2), 7b, and 7g (both of type II), which have low-nanomolar affinity for Eph kinases in vitro and a good selectivity profile on a panel of 453 human kinases (395 nonmutant). Surface plasmon resonance measurements show a very slow unbinding rate (1/115 min) for inhibitor 7m. Slow dissociation is consistent with a type II binding mode in which the hydrophobic moiety (trifluoromethyl-benzene) of the inhibitor is deeply buried in a cavity originating from the displacement of the Phe side chain of the so-called DFG motif as observed in the crystal structure of compound 7m. The inhibitor 11d displayed good in vivo efficacy in a human breast cancer xenograft.

Identification and optimization of anthranilic sulfonamides as novel, selective cholecystokinin-2 receptor antagonists

A high throughput screening approach to the identification of selective cholecystokinin-2 receptor (CCK-2R) ligands resulted in the discovery of a novel series of antagonists, represented by 1-[2-[(2,1,3-benzothiadiazol-4- ylsulfonyl)amino]-5-chlorobenzoyl]-piperidine (1; CCK-2R, pKI = 6.4). Preliminary exploration of the structure-activity relationships around the anthranilic ring and the amide and sulfonamide moieties led to a nearly 50-fold improvement of receptor affinity and showed a greater than 1000-fold selectivity over the related cholecystokinin-1 receptor. Pharmacokinetic evaluation led to the identification of 4-[4-iodo-2-[(5-quinoxalinylsulfonyl)amino]benzoyl]- morpholine, 26d, a compound that demonstrates promising pharmacokinetic properties in the rat and dog with respect to plasma clearance and oral bioavailability and is a potent inhibitor in vivo of pentagastrin-stimulated acid secretion in the rat when dosed orally.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 17056-99-4, you can also check out more blogs about17056-99-4

Synthesis and biological evaluation of novel 2-arylamino-3-(arylsulfonyl) quinoxalines as PI3Kalpha inhibitors

A series of novel 2-arylamino-3-(arylsulfonyl)quinoxalines was synthesized through a newly developed approach. All synthesized target compounds were screened for their cytotoxicities against cancer cell lines including PC3, A549, HCT116, HL60 and KB. Representative compounds with favorable cytotoxicities were tested for their PI3Kalpha inhibitory activities. Among the synthesized target compounds, 17 (PI3Kalpha IC50: 0.07 muM) displayed the most potent cellular activities (IC50 values of 0.14 muM, 0.07 muM, 0.95 muM and 0.05 muM against PC3, A549, HCT116 and HL 60, respectively).

Synthesis and properties of 2,3-heteroannulated thiochromones – hetero analogs of thioxanthone

[Figure not available: see fulltext.] This article provides generalized and systematic data on the synthesis and some properties of 2,3-heteroannulated thiochromones that can be viewed as hetero analogs of thioxanthone. The main emphasis is on various methods for the preparation of compounds that are arranged according to the starting material structures. Analysis of literature data shows that the most valuable and commonly used starting materials for obtaining hetero analogs of thioxanthone are substituted thiophenols, 2(3)-functionalized thiochromone derivatives, as well as 4-hydroxydithiocoumarins and (?-haloaroyl)thioacetamides. Azathioxanthones (thiochromenopyridines) are the most studied examples of 2,3-heterothiochromones. This review is concluded with some basic facts about 2,3-carboannulated thiochromones. A total of 99 references are given.
