Used in cancer research, particularly targeting hypoxic tumor cells. It inhibits carbonic anhydrase IX (CAIX), an enzyme overexpressed in various solid tumors under low oxygen conditions. By blocking CAIX activity, this compound helps disrupt pH regulation in cancer cells, leading to reduced tumor growth and metastasis. It is studied for potential use in combination with chemotherapy and radiotherapy to enhance treatment efficacy. Also serves as a tool compound for validating CAIX as a therapeutic target in preclinical models.
