Tubulin/HDAC-IN-1 is a dual inhibitor of tubulin and HDAC8, interacting with tubulin via CH/pi interactions and with HDAC8 through hydrogen bonds. It effectively inhibits tubulin polymerization and selectively targets HDAC8 with an IC50 of 150 nM. Additionally, Tubulin/HDAC-IN-1 demonstrates cytotoxicity against various human cancer cells, induces cell cycle arrest in the G2/M phase, and triggers cell apoptosis, making it valuable for studying hematologic and solid tumors, including neuroblastoma and leukemia [1].
