1,2-Dihydro-1-oxopyrrolo<3,2,1-kl>phenothiazine-2-carboxamides and Congeners, Dual Cyclooxygenase/5-Lipoxygenase Inhibitors with Antiinflammatory Activity

A series of 1,2-dihydro-1-oxopyrrolo<3,2,1-kl>phenothiazine, 1,2-dihydro-1-oxopyrrolo<3,2,1-kl>phenoxazine, and 1,2-dihydro-1-oxopyrrolo<3,2,1-de>acridine-2-carboxamides were prepared by reaction of 1,2-dihydro-1-oxopyrrolo<3,2,1-kl>phenothiazine or other corresponding phenoxazine and acridan ethyl or methyl esters with appropriate amines.Several members of this family were found to be potent, dual inhibitors of cyclooxygenase and 5-lipoxygenase pathways of arachidonic acid metabolism and to have in vivo antiinflammatory activity in the rat foot edema assay.Structure-activity relationships within this family of compounds are described. 1,2-Dihydro-N-(2-thiazolyl)-1-oxopyrrolo<3,2,1-kl>phenothiazine-1-carboxamide (34) was found to be one of the best compounds to display potent cyclooxygenase/5-lipoxygenase inhibition of arachidonic acid metabolism.Its IC50s against the enzymes sourced from rat basophillic leukemia-1 (RBL-1) cells were 0.07 and 1.4 muM, respectively.It was active in the rat foot edema test for antiinflammatory effect (48percent inhibition at 33 mg/kg po) and in the mouse phenylbenzoquinone induced writhing test for analgesic effect (93percent inhibition at 32 mg/kg po).

Design of Gut-Restricted Thiazolidine Agonists of G Protein-Coupled Bile Acid Receptor 1 (GPBAR1, TGR5)

Bile acid signaling and metabolism in the gastrointestinal tract have wide-ranging influences on systemic disease. G protein-coupled bile acid receptor 1 (GPBAR1, TGR5) is one of the major effectors in bile acid sensing, with demonstrated influence on metabolic, inflammatory, and proliferative processes. The pharmacologic utility of TGR5 agonists has been limited by systemic target-related effects such as excessive gallbladder filling and blockade of gallbladder emptying. Gut-restricted TGR5 agonists, however, have the potential to avoid these side effects and consequently be developed into drugs with acceptable safety profiles. We describe the discovery and optimization of a series of gut-restricted TGR5 agonists that elicit a potent response in mice, with minimal gallbladder-related effects. The series includes 12 (TGR5 EC50: human, 143 nM; mouse, 1.2 nM), a compound with minimal systemic availability that may have therapeutic value to patients with type 2 diabetes mellitus, nonalcoholic steatohepatitis, or inflammatory bowel disease.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 3080-99-7.

Regioselective synthesis of heterocycles containing nitrogen neighboring an aromatic ring by reductive ring expansion using diisobutylaluminum hydride and studies on the reaction mechanism

(Chemical Equation Presented) A systematic investigation of the reductive ring-expansion reaction of cyclic ketoximes fused to aromatic ringswith diisobutylaluminum hydride (DIBALH) is described. This reaction regioselectively afforded a variety of five- to eight-membered bicyclic heterocycles or tricyclic heterocycles containing nitrogen neighboring an aromatic ring, including indoline, 1,2,3,4,5,6-hexahydrobenz[b]azocine, 3,4-dihydro-2H-benzo[b] [1,4]oxazine, 2,3,4,5-tetrahydrobenzo[b][1,4]thiazepine, 1,2,3,4,5,6- hexahydroazepino[3,2-b]-indole, 2,3,4,5-tetrahydro-1H-benzothieno[2,3-b]azepine, 2,3,4,5-tetrahydro-1H-benzothieno[3,2-b]-azepine, 5,6-dihydrophenanthridine, and 5,6,11,12-tetrahydrodibenz[b, f]azocine. The reaction mechanism leading to the rearrangement was investigated on the basis of the restricted Becke three-parameter plus Lee-Yang-Parr (B3LYP) density functional theory (DFT) with the 6-31G (d) basis set. It was found that the reaction proceeds through a three-centered transition state via a stepwise mechanism because the potential energy curve along the intrinsic reaction coordinate (IRC) had twomaxima (saddle points; TS1 and TS2) and the partial phenonium cation intermediate C. In addition to cyclic ketoximes fused to aromatic rings, the reactions of various cyclic and acyclic ketoximeswere examined to investigate preference of migrating group. It was found that themore electron-rich group migrated preferentially to give the corresponding secondary amines.

Selective N-alkylation of arylamines with alkyl chloride in ionic liquids: Scope and applications

An efficient N-selective alkylation of primary aromatic amines in molten quaternary ammonium salts, as the solvent, under relatively mild and base-free conditions is presented. On the basis of the Kamlet-Taft parameters and the nucleophilicity of the IL (ionic liquid) anions, the influence of the ionic liquid was evaluated. This protocol was validated on a larger multigram scale and with the syntheses of bioactive heterocycles (e.g., 1,4-benzothiazine and quinoxalines) and new efficient MALDI matrixes. Copyright
