Abstract

The transforming growth factor β (TGF-β) type 1 receptor (ALK5) plays a pivotal role in the tumor microenvironment, making it an attractive target for therapeutic intervention. Small-molecule inhibitors of TGFβR1 offer a promising approach for the treatment of malignant tumors. In this study, a series of 1H-pyrrolo[2,3-b]pyridine derivatives were identified as novel TGFβR1 inhibitors. The most potent candidate, compound 7w, demonstrated inhibition of SMAD2/3 phosphorylation and Hep3B cell viability, with IC50 values of 160.3 nM and 228 μM, respectively. Compound 7w showed a synergistic anti-proliferation and pro-apoptotic effect when combined with sorafenib, highlighting its potential as a promising lead for the development of potential Anticancer therapies.
