SH-FAPI-4

SH-FAPI-4 is a specific fibroblast activation protein inhibitor (FAPI) compound that belongs to the FAPI family of molecules. SH-FAPI-4 is expected to selectively accumulate in FAP-positive tumors and disrupt the functions of cancer-associated fibroblasts (CAFs) within the tumor microenvironment. By inhibiting FAP activity, this compound aims to potentially slow tumor growth, enhance the efficacy of other cancer treatments, and modulate the tumor microenvironment.
