| | Tubulysin B Usage And Synthesis |
| Description |
Tubulysin B is a highly cytotoxic peptide and potent microtubule destabilizing agent isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis. Tubulysin B has IC50 values in the picomolar range against many cancer cell lines, including those with multidrug-resistant properties. It is a cytotoxic activity tubulysin which inhibits tubulin polymerization and leads to cell cycle arrest and apoptosis.
