Tubulosine is an alkaloid that functions as a selective inhibitor of the Janus kinase 3 (JAK3) with an IC50 of 9.9 nM. It exhibits enhanced inhibition of JAK3 compared to other JAK family members, with IC50 values of 69.5 nM for JAK1, 84.9 nM for JAK2, and 76.3 nM for TYK2. Tubulosine induces both apoptotic and necrotic/autophagic cell death in cancer cells and disrupts peptide chain elongation in eukaryotic polysomes. This compound demonstrates promising anticancer activity, particularly in breast cancer cell lines, making it a valuable tool for cancer research.
