Targeting FGFRs for tumor therapy: current status and novel strategies Supplementary dataset

The FGF receptors (FGFRs) belong to a family of receptor tyrosine kinases. Abundant evidence shows

that FGFRs are closely related to tumor cell invasion and angiogenesis. Hence, targeted modulation

of FGFRs has become an effective strategy for cancer treatment. Recently, the development of smallmolecule

inhibitors targeting FGFRs has been extensively studied, and three inhibitors have been approved

for marketing. Based on the clinical problems with the current inhibitors, there is a need to develop

novel inhibitors and technologies to address the pitfalls. This review summarizes recent advances in

small-molecule inhibitors targeting FGFRs, focusing on structure–activity relationships. Moreover, recent

progress of novel technologies are summarized to provide a reference for promoting the application of

drugs targeting FGFRs in tumor therapy.
