CKD-516 (CAT: I010176) is a valine prodrug of (S516) and functions as a vascular disrupting agent (VDA) with potential applications in the treatment of solid cancers. It acts as a tubulin inhibitor, specifically targeting the tubulin of the endothelial cytoskeleton. By selectively disrupting tubulin, CKD-516 interferes with the formation and stability of microtubules in endothelial cells, leading to the disruption of the tumor vasculature. This disruption of the tumor blood supply can result in tumor regression and inhibition of tumor growth. CKD-516’s ability to selectively target endothelial tubulin makes it a promising candidate for the treatment of solid cancers.
