Grade: GMP product Tested for sterility and bacterial endotoxins Description: SH-FAPI-4 is a selective fibroblast activation protein (FAP) inhibitor from the FAPI family. It is designed to accumulate specifically in FAP-positive tumors and interfere with the function of cancer-associated fibroblasts (CAFs) in the tumor microenvironment. By inhibiting FAP activity, SH-FAPI-4 aims to slow tumor progression, enhance the effectiveness of other cancer therapies, and modulate the tumor environment.
