Microtubule/Tubulin

SS28, a SRT501 analog with oral bioavailability, inhibits tubulin polymerization to cause cell cycle arrest at G2/M phase. SS28 results in apoptosis rather than necrosis tubulin.

Sagopilone is a fully synthetic low-molecular-weight epothilone with potential antineoplastic activity.

DM1-SMe is a potent maytansinoid microtubular inhibitor and an unconjugated DM1 as a mixed disulfide with thiomethane to cap its sulfhydryl group.

Tubulysin family of secondary metabolites are originally isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis. These compounds are potent microtubule destabilizing agents with IC50 values in the picomolar range against many cancer cell lines, including those with multidrug resistant properties. Tubulysins have limited therapeutic utility due to severe toxicity, so Tubulysins are ideal candidates to be incorporated into molecule drug conjugate (SMDC) delivery system.

VERU-111 is a novel, oral α and β tubulin inhibitor that blocks tubulin polymerization and is not a substrate for multi-drug resistance mechanisms.

CCB02 is a selective CPAP-tubulin interaction inhibitor, binding to tubulin and competing for the CPAP binding site of β-tubulin, with an IC50 of 689 nM, and shows potent anti-tumor activity.

Tubulin inhibitor 1 is a tubulin inhibitor, inhibits tubulin polymerization.

MPT0B392 is demonstrated to be a novel microtubule-depolymerizing agent and enhances the cytotoxicity of sirolimus in sirolimus-resistant acute leukemic cells and the multidrug resistant cell line.

Latrunculin A (LAT-A) is a toxin isolated from the red sea sponge Latrunculia magnifica, binds to actin monomers, inhibits polymerization of actin, with Kds of 0.1, 0.4, 4.7 μM and 0.19 μM for ATP-actin, ADP-Pi-actin, ADP-actin and G-actin, respectively.

Tubulysin A(TubA) is a myxobacterial product that can function as an antiangiogenic agent in many in vitro assays; anti-microtubule, anti-mitotic, an apoptosis inducer, anticancer, anti-angiogenic, and antiproliferative.

Valecobulin (CKD516) is a valine prodrug of (S516) and a vascular disrupting agent (VDA). Valecobulin is a potent β-tubulin polymerization inhibitor with marked antitumor activity against murine and human solid tumors.

Eribulin (E7389) is a microtubule targeting agent that is used in the treatment of metastatic breast cancer.

Lexibulin 2Hcl (CYT-997 2Hcl) is a potent tubulin polymerisation inhibitor with IC50 of 10-100 nM in cancer cell lines; with potent cytotoxic and vascular disrupting activity in vitro and in vivo.

PF-06380101 (Aur0101), an auristatin microtubule inhibitor, is a cytotoxic Dolastatin 10 analogue.

Tasidotin hydrochloride is a peptide analog of the antimitotic depsipeptide dolastatin 15, as an inhibitor of microtubule assembly and microtubule dynamics.
