Tubulysin B is an agent of potent microtubule destabilizing and highly cytotoxic peptide isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis.
CCK2R Ligand-Linker Conjugate 1 is a hydrophilic peptide linker that conjugates to the cytotoxic antimicrotubule agents Desacetyl Vinblastine Hydrazide (DAVBH) and Tubulysin B Hydrazide (TubBH) as ligand-linker conjugates[1].
