CA4P has been shown in the laboratory to shut down the blood supply to tumours. It is one of the first vascular targeting drugs to be tested in patients. This drug was originally isolated from the African Bush Willow. The first studies in patients with this drug were aimed at finding out whether it can be safely given to patients, what side effects it produces and whether it can actually shut down the blood supply to human tumours.

CA4P binds tubulin with a higher efficacy than colchicines, and was therefore initially investigated as an anti-mitotic agent. However, it was later observed to also induce vascular shutdown and necrosis in tumours. Clinical trials have revealed its positive effects, either as a single agent or in combination with chemotherapy, in patients with ovarian, lung or anaplastic thyroid cancer. Biochemical analyses revealed that CA4P rapidly diminished the tyrosine phosphorylation of VE-cadherin and beta-catenin, thereby blocking the endothelial signalling pathway that is necessary for maintaining a functional endothelial cell structure and survival.
