The present invention relates to pharmaceutical compositions containing tumor-selective targeted inhibitor glycoconjugates. These bioconjugates are ALK5 inhibitors covalently bound to biocompatible carrier molecules which selectively target and specifically bind to Muc4 that is overexpressed on a variety of tumor cell types. The ALK5 inhibitors are conjugated to tumor targetable glycans through a covalent linker. Preferably the acid-labile linker is designed to be stable in plasma and releases pharmacologically active inhibitors through acid-catalyzed hydrolysis in the acidic environment of the target tumor where the inhibitor activity is restored. Because the glycoconjugates are stable at physiological pH and in plasma, they advantageously reduce undesirable systemic ALK5 inhibitor activity; however, the preferable glycoconjugates are acid-labile conjugates that can be hydrolyzed upon reaching the more acid environment of the tumor.
[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.
