VT-104 is a potent and selective TEAD Auto-palmitoylation inhibitor that Inhibits Proliferation and Tumor Growth of NF2-deficient Mesothelioma. VT104 is an analog of VT102, which has improved potency and good oral pharmacokinetics in mice. VT104 prevented palmitoylation of the TEAD1 protein. VT104 showed excellent orally bioavailability and long half-lives, which inhibits tumor growth and also lead to shrinkage of established tumors in preclinical models of human mesothelioma CDX models deficient in functional Merlin.
