Interruption of TGF beta signaling through inhibition of the TGF beta R1 kinase domain may prove to have beneficial effect in both fibrotic and oncological diseases. Herein we describe the SAR of a novel series of TGF beta R1 kinase inhibitors containing a pyrazolone core. Most TGF beta R1 kinase inhibitors described to date contain a core five-membered ring bearing N as H-bond acceptor. Described herein is a novel strategy to replace the core structure with pyrazolone ring, in which the carbonyl group is designed as an H-bond acceptor to interact with catalytic Lys 232.

[EN] The invention is related to compounds of formula (I) as antagonists of the TGFß family type I receptors, Alk5 and/or AIk 4, compositions and methods of use. The compounds of formula (I) can be employed in the prevention and/or treatment of diseases such as fibrosis (e.g., renal fibrosis, pulmonary fibrosis, and hepatic fibrosis), progressive cancers, or other diseases for which reduction of TGFß family signaling activity is desirable. [FR] L'invention concerne des composés de formule (I) utilisés comme antagonistes des récepteurs de type I de la famille du TGFß, Alk5 et/ou AIk 4, des compositions et des procédés d'utilisation. Les composés de formule (I) peuvent être utilisés dans la prévention et/ou le traitement de maladies telles que la fibrose (p. ex. la fibrose rénale, la fibrose pulmonaire et la fibrose hépatique), cancers évolutifs ou autres maladies pour lesquelles la diminution de l'activité de signalisation de la famille du TGFß est désirable.

The invention is related to compounds of formula (I) as antagonists of the TGFβ family type I receptors, Alk5 and/or AIk 4, compositions and methods of use. The compounds of formula (I) can be employed in the prevention and/or treatment of diseases such as fibrosis (e.g., renal fibrosis, pulmonary fibrosis, and hepatic fibrosis), progressive cancers, or other diseases for which reduction of TGFβ family signaling activity is desirable.
