Tubulin inhibitor 38

Tubulin Inhibitor 38 (Compound 14), a tetrazole-based agent, demonstrates significant antiproliferative effects by inducing mitotic arrest and blocking the cell cycle at the G2/M phase, ultimately triggering apoptosis. Administered at 100 nM for 24 hours, it shows considerable cytotoxicity and selectivity within HeLa, MCF7, and U87 MG cell lines [1].
