Tubulysin M 

Tubulysin M is a highly cytotoxic anti-microtubule toxin (anti-microtubule toxins) that is synthesized as an ADC cytotoxin (ADC Cytotoxin). Tubulysin M can be isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis. Tubulysin M displays extremely potent cytotoxic activity in mammalian cells, including multidrug-resistant cell lines, with IC₅₀ values in the low nanomolar range. Tubulysin M inhibits microtubule/tubulin polymerization and leads to cell cycle arrest and apoptosis^[1][2][3].
