(S,R,S)-AHPC-C2-amide-benzofuranylmethyl-pyridine is a dual-targeting PROTAC molecule. (S,R,S)-AHPC-C2-amide-benzofuranylmethyl-pyridine not only targets the ubiquitination and degradation of Smad3, but also elevates the protein level of HIF-α, thereby exerting multi-pathway anti-fibrotic and renoprotective effects. (S,R,S)-AHPC-C2-amide-benzofuranylmethyl-pyridine can be used in a wide range of tumor studies including cancers with KRAS inhibitor resistance, covering pancreatic ductal adenocarcinoma, acute myeloid leukemia, and various soft tissue sarcomas (such as fibrosarcoma, liposarcoma, chondrosarcoma, etc.). (S,R,S)-AHPC-C2-amide-benzofuranylmethyl-pyridine can also be applied to research related to various solid tumors and hematological malignancies, involving multiple cancer types such as colon cancer, breast cancer, ovarian cancer, non-small cell lung cancer, glioblastoma, and melanoma .
