Valecobulin (CKD516), a valine prodrug of (S516) and a vascular disrupting agent (VDA), is a potent beta-tubulin polymerization inhibitor with marked antitumor activity against murine and human solid tumors[1][2].
The size change of the tumor in VX2 liver tumor-bearing rabbits is significantly smaller in the Valecobulin (CKD516)( 5, 9, or 12 mg/m2, i.v.)- treated group than in control group[2].|| Animal Model:|VX2 liver tumor-bearing rabbits (Male New Zealand White rabbits weighing between 2.5 and 3.5 kg)[2]. |Dosage:|Dissolved in 5 mL of saline at a dose of 5, 9, or 12 mg/m2 of body surface area.|Administration:|Intravenous injection once.|Result:|The size change of the tumors was significantly smaller in the treated group than in control group.

Involvement of ER stress and reactive oxygen species generation in anti-cancer effect of CKD-516 for lung cancer
Cancer Chemother Pharmacol 2020 Apr;85(4):685-697.PMID:32157413DOI:10.1007/s00280-020-04043-x
Purpose: CKD-516 (Valecobulin), a vascular-disrupting agent, inhibits microtubule elongation. We evaluated the effect of CKD-516 on lung cancer cells and the underlying molecular mechanisms. Methods: The effects of S516, an active metabolite of CKD-516, were evaluated in HUVECs and three lung cancer cell lines and by a microtubule polymerization assay. Tubulin cross-linking was used to identify the binding site of S516 on tubulin, and Western blotting was performed to identify the intracellular pathways leading to cell death. Subcutaneous lung cancer xenograft models were used to assess the in vivo effect of CKD-516 on tumor growth. Results: S516 targeted the colchicine binding site on β-tubulin. In lung cancer cells, S516 increased endoplasmic reticulum (ER) stress and induced reactive oxygen species (ROS) generation by mitochondria and the ER. In addition, CKD-516 monotherapy strongly inhibited the growth of lung cancer xenograft tumors and exerted a synergistic effect with carboplatin. Conclusion: The findings suggest that CKD-516 exerts an anticancer effect in company with inducing ER stress and ROS production via microtubule disruption in lung cancer cells. CKD-516 may thus have therapeutic potential for lung cancer.
