Senexins are potent and selective quinazoline inhibitors of CDK8/19 Mediator kinases. To improve their potency and metabolic stability, quinoline-based derivatives were designed through a structure-guided strategy based on the simulated drug–target dockin

Paragraph 0108; 0110-0111, (2020/03/09)
Disclosed herein are quinoline-based compounds and method for inhibiting CDK8 or CDK19 for the intervention in diseases, disorders, and conditions. The quinoline-based composition comprise substituents at quinoline ring positions 4 and 6, wherein the substituent at position 4 is selected from a substituted or unsubstituted arylalkylamine or a substituted or unsubstituted arylhetrocyclylamine. Pharmaceutical compositions comprising the substituted qunioline compositions, methods of inhibiting CDK8 or CDK19, and methods of treating CDK8/19-associated diseases, disorders, or conditions are also disclosed.

C-H activation of position 3 of a substituted pyrazole ring catalyzed by palladium(II) was straightforward and convenient for arylated or heteroarylated 5,5-dimethyl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazoles. Moreover, we introduced simple protection of the nitrogen in the pyridin-2-yl directing group, which otherwise does not allow a cross-coupling reaction, by transformation to the N-oxide. Selected final products were reasonably selective ALK5 kinase inhibitors.

Highly efficient thermal cyclization reactions of alkylidene esters in continuous flow to give aromatic/heteroaromatic derivatives
Lengyel, László,Nagy, Tibor Zs.,Sipos, Gellért,Jones, Richard,Dormán, Gy?rgy,ürge, László,Darvas, Ferenc
scheme or table, p. 738 - 743 (2012/03/08)
Intramolecular thermal cyclization and benzannulation reactions of the Gould-Jacobs and Conrad-Limpach types were performed in a designed continuous flow reactor system at temperatures in the range of 300-360°C and under high pressure conditions (100-160 bar) with very short residence times (0.45-4.5 min) in tetrahydrofuran as a low-boiling point solvent. Substituted heteroaromatic compounds including pyridopyrimidinones and hydroxyquinolines were synthesized in moderate to high yields. Application of the reaction conditions also allows the synthesis of naphthol and biphenyl derivatives. The procedure involves an easy work-up and the non-batchwise preparative synthesis method is suitable for automation.

Assembly of 4-aminoquinolines via palladium catalysis: A mild and convenient alternative to SNAr methodology

, p. 2232 - 2235 (2007/10/03)
4-Aminoquinolines, classically prepared via SNAr chemistry from an amine and 4-haloquinoline, are important scaffolds in medicinal chemistry. Interest in these compounds prompted us to explore palladium catalysis as an alternative to the existing methods for their preparation. Initial results followed by an iterative screening paradigm confirmed Pd(OAc)2/ DPEphos/K3PO4 as a mild and convenient alternative for the formation of the C-N bond in 4-aminoquinolines. A description of the screen and the scope of this methodology are discussed herein.
Synthesis of ring-substituted 4-aminoquinolines and evaluation of their antimalarial activities
Madrid, Peter B.,Sherrill, John,Liou, Ally P.,Weisman, Jennifer L.,DeRisi, Joseph L.,Guy, R. Kiplin
, p. 1015 - 1018 (2007/10/03)
A simple two-step synthesis method was used to make 51 B-ring-substituted 4-hydroxyquinolines allowing analysis of the effect of ring substitutions on inhibition of growth of chloroquine sensitive and resistant strains of Plasmodium falciparum, the dominant cause of malaria morbidity. Substituted quinoline rings other than the 7-chloroquinoline ring found in chloroquine were found to have significant activity against the drug-resistant strain of P. falciparum W2.
