ICD inducer-2
ICD inducer-2 is a immunogenic cell death inducer. ICD inducer-2 binds to the colchicine binding site on tubulin to inhibit tubulin polymerization. ICD inducer-2 exhibits broad-spectrum antiproliferative activity across multiple cancer cell lines. ICD inducer-2 inhibits cells migration, causes G2/M phase and induces apoptosis. ICD inducer-2 promotes infiltration of CD4+ and CD8+ T cells into the tumor microenvironment. ICD inducer-2 downregulates antiapoptotic protein Bcl-2, upregulates proapoptotic proteins Bax and Bim-1, and increases cleaved caspase 3, cleaved caspase 9, and cleaved PARP levels. ICD inducer-2 overcomes paclitaxel resistance in xenograft models and achieves tumor growth inhibition. ICD inducer-2 can be used for the research of cancer, such as lung carcinoma.
