5-Lipoxygenase-Activating Protein Inhibitors: Development of 3-[3-tert-Butylsulfanyl-1-[4-(6-methoxy-pyridin-3-yl)-benzyl]-5-(pyridin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic Acid (AM103)
摘要:
The potent and selective 5-lipoxygenase-activating protein leukotriene synthesis inhibitor 3-[3-tert-butyl-sulfanyl-1-[4-(6-methoxy-pyridin-3-yl)-benzyl]-5-(pyridin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethylpropionic acid (11j) is described. Lead optimization was designed to afford compounds with superior in vitro and in vivo inhibition of leukotriene synthesis in addition to having excellent pharmacokinetics and safety in rats and dogs. The key structural features of these new compounds are incorporation of heterocycles on the indole N-benzyl substituent and replacement of the quinoline group resulting in compounds with excellent in vitro and in vim activities, superior pharmacokinetics, and improved physical properties. The methoxypyridine derivative 11j has an IC50 of 4.2 nM in a 5-lipoxygenase-activating protein (FLAP) binding assay, an IC50 of 349 nM in the human blood LTB4 inhibition assay, and is efficacious in a murine ovalbumin model of allergen-induced asthma. Compound 11j was selected for clinical development and has successfully completed phase I trials in healthy volunteers.
Described herein is the FLAP inhibitor 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, or a pharmaceutically acceptable salt thereof. Also described are methods of preparing the FLAP inhibitor, or a pharmaceutically acceptable salt thereof, including solvates, and polymorphs thereof. Also described herein are pharmaceutical compositions suitable for administration to a mammal that include the FLAP inhibitor, or a pharmaceutically acceptable salt thereof, and methods of using such pharmaceutical compositions for treating respiratory conditions or diseases, as well as other leukotriene-dependent or leukotriene mediated conditions or diseases.

Disclosed herein are compositions and compounds that combine an inhibitor of
5
-lipoxygenase activating protein (FLAP) and a modulator of NO levels in a mammal. The NO modulator can be an agent that induces the production of NO in a mammal, or can be an agent that itself produces NO in the mammal. Further disclosed herein are strategies for synthesizing such compounds, and methods for testing whether the combination compounds and compositions provide a desired benefit. Also disclosed herein are pharmaceutical compositions and formulations that combine a FLAP inhibitor and an NO modulator. Further described herein are methods for using such compositions and compounds for the treatment of diseases, conditions, and disorders in a mammal, including a human. Such treatment methods include the separate administration of a FLAP inhibitor and a NO modulator to the mammal, and the simultaneous administration of a FLAP inhibitor and a NO modulator to the mammal.
