Hsp90-IN-46 is a Hsp90 inhibitor. Hsp90-IN-46 exhibits broad-spectrum antiproliferative activity against tumor cell lines. Hsp90-IN-46 inhibits breast cancer cell proliferation by reducing colony formation and downregulating the proliferation marker Ki-67. Hsp90-IN-46 inhibits Hsp90 and its ATPase activity, downregulates the downstream substrate oncoproteins HER2 and CDK4, and moderately induces the heat shock response. Hsp90-IN-46 shows significant antitumor activity in a mouse model of triple-negative breast cancer tumor xenografts. Hsp90-IN-46 can be used for research on various cancers including triple-negative breast cancer, leukemia, non-small cell lung cancer, colon cancer, ovarian cancer, renal cancer, prostate cancer.
