alpha-tocopheryloxyacetic acid
An orally bioavailable vitamin E derivative with potential antineoplastic and immunostimulating activities. Upon administration, alpha-tocopheryloxyacetic acid (alpha-TEA) induces tumor autophagy; the autophagosomes formed, which carry tumor associated antigens (TAAs), allow for increased cross-presentation of TAAs by professional antigen-presenting cells (APCs). This activates a T-cell-mediated T-helper type 1 (TH1) response, generates a cytotoxic T-lymphocyte (CTL) response against cancer cells, and reduces the frequency of regulatory T-cell (Treg) differentiation. In addition, alpha-TEA modulates the release of various cytokines and chemokines and induces tumor cell apoptosis. Altogether, this results in decreased tumor cell proliferation. Check for active clinical trials using this agent. (NCI Thesaurus)
