REDUCTION OF PRO-INFLAMMATORY HDL USING A LEUKOTRIENE INHIBITOR
-
Paragraph 00200, (2018/09/12)
A method involving the administration of a therapeutically effective amount of a leukotriene inhibitor, a pharmaceutically acceptable salt, a pharmaceutically acceptable N-oxide, a pharmaceutically active metabolite, a pharmaceutically acceptable prodrug, or pharmaceutically acceptable solvate thereof to a human for reducing a level of pro-inflammatory HDL in the human. Various examples of leukotriene inhibitors, including 3-[3-tert-butylsulfanyl-1-[4-(6-ethoxy-pyridin- 3-yl)-benzyl]-5-(5-methyl-pyridin-2-ylmethoxy)-1H-indol-2-yl]-2, 2-dimethyl-propionic acid, are disclosed for administration for the reduction of pro-inflammatory HDL in a human. Reduction of pro-inflammatory HDL by the leukotriene inhibitor may include conversion of at least a portion of pro-inflammatory HDL to anti-inflammatory HDL.
Enantioselective Intermolecular [2 + 2] Photocycloaddition Reactions of 2(1H)-Quinolones Induced by Visible Light Irradiation

In the presence of a chiral thioxanthone catalyst (10 mol %) the title compounds underwent a clean intermolecular [2 + 2] photocycloaddition with electron-deficient olefins at λ = 419 nm. The reactions not only proceeded with excellent regio- and diastereoselectivity but also delivered the respective cyclobutane products with significant enantiomeric excess (up to 95% ee). Key to the success of the reactions is a two-point hydrogen bonding between quinolone and catalyst enabling efficient energy transfer and high enantioface differentiation. Preliminary work indicated that solar irradiation can be used for this process and that the substrate scope can be further expanded to isoquinolones.

A novel method for the regioselective C2-chlorination of heterocyclic N-oxides has been developed. PPh3/Cl3CCN were used as chlorinating reagents and the desired N-heterocyclic chlorides were obtained smoothly in satisfactory yields. The reactions proceeded in a highly efficient and selective manner across a broad range of substrates demonstrating excellent functional group tolerance. In addition, this chlorination reaction can be used for the modification of N-heterocyclic scaffolds of appealing ligands and pharmaceuticals.

A facile and inexpensive route for the preparation of α-halobenzopyridines from α-unsubstituted benzopyridines via N-methylbenzopyridin-α-ones was developed. α-Unsubstituted benzopyridines were converted easily into the corresponding N-methylbenzopyridin-α-ones, which were halogenated using PPh3-TCICA or PPh3-DBICA without using solvent to give α-halobenzopyridines.

Since high levels of nitric oxide (NO) are implicated in neurodegenerative disorders, inhibition of the neuronal isoform of nitric oxide synthase (nNOS) and reduction of NO levels are therapeutically desirable. Nonetheless, many nNOS inhibitors mimic l-arginine and are poorly bioavailable. 2-Aminoquinoline-based scaffolds were designed with the hope that they could (a) mimic aminopyridines as potent, isoform-selective arginine isosteres and (b) possess chemical properties more conducive to oral bioavailability and CNS penetration. A series of these compounds was synthesized and assayed against purified nNOS enzymes, endothelial NOS (eNOS), and inducible NOS (iNOS). Several compounds built on a 7-substituted 2-aminoquinoline core are potent and isoform-selective; X-ray crystallography indicates that aminoquinolines exert inhibitory effects by mimicking substrate interactions with the conserved active site glutamate residue. The most potent and selective compounds, 7 and 15, were tested in a Caco-2 assay and showed good permeability and low efflux, suggesting high potential for oral bioavailability.
A practical and mild chlorination of fused heterocyclic N-oxides

supporting information, p. 7130 - 7132 (2015/02/02)
Fused azine N-oxides were selectively chlorinated at C2 in moderate to excellent yields, employing Vilsmeier reagent as both the activating agent and the nucleophilic chloride source. Remarkable features of the method include simple operation, mild reaction conditions, a wide substrate scope, and the use of only stoichiometric amount of POCl3. The potential extension of this method to a one-pot oxidation/chlorination sequence that obviates the need for isolation of the N-oxide intermediates is also validated.
