SAR-Based Optimization of a 4-Quinoline Carboxylic Acid Analogue with Potent Antiviral Activity
摘要:
It is established that drugs targeting viral proteins are at risk of generating resistant strains. However, drugs targeting host factors can potentially avoid this problem. Herein, we report structure-ctivity relationship studies leading to the discovery of a very potent lead compound 6-fluoro-2-(5-isopropyl-2-methyl-4-phenoxyphenyl) quinoline -4-carboxylic acid (C44) that inhibits human dihydroorotate dehydrogenase (DHODH) with an IC50 of 1 nM and viral replication of VSV and WSN-Influenza with an EC50 of 2 nM and 41 nM. We also solved the X-ray structure of human DHODH bound to C44, providing structural insight into the potent inhibition of biaryl ether analogues of brequinar.
(EN) 4-Quinoline-carboxylic acid derivatives, such as 2-(2'-fluoro-1,1'-biphenyl-4-yl)-6-fluoro-3-methyl-4-quinoline carboxylic acid, in combination with other immunosuppressive agents are useful for the treatment and/or prevention of transplantation rejection, graft vs. host disease, autoimmune diseases, and chronic inflammatory disease.(FR) Des dérivés d'acide quinoléine-4-carboxylique, par exemple l'acide 2-(2'-fluoro-1,1'-biphényle-4-yle)-6-fluoro-3-méthyle-4-quinoléine carboxylique, associés à d'autres agents immunosuppresseurs, sont utiles au traitement et/ou à la prévention du rejet du greffon, de la réaction du greffon contre l'hôte, des maladies auto-immunes et des affections inflammatoires chroniques.

Interleukin-2 (IL-2) in combination with 4-quinoline carboxylic acids and derivatives thereof, such as 2-(2′-fluoro-1,1′-biphenyl-4-yl)-6-fluoro-3-methyl-4-quinoline carboxylic acid, are useful for the treatment of solid tumors in mammals. The tumor-inhibiting effect of the combination of IL-2 and quinoline carboxylic acids exceeds the effect of either agent alone.

4-Quinolinecarboxylic acids and derivatives thereof, such as 2-(2′-fluoro-1,1′-biphenyl-4-yl)-6-fluoro-3-methyl-4-quinolinecarboxylic acid, are useful as immunomodulatory and anti-inflammatory agents. Pharmaceutical formulations containing such compounds are useful for the treatment of autoimmune diseases, transplantation rejection, graft vs. host disease, and chronic inflammatory disease such as rheumatoid arthritis.
