Synthetic and natural alkyl phosphates, also known as phosphoantigens, stimulate the proliferation of ??-T lymphocytes.{17387} Isopentenyl pyrophosphate, and related derivatives including (E)-hydroxy-dimethyl-allyl pyrophosphate ((E)-HDMAPP), are particularly effective activators of ??-T cells.{17389,17388} (E)-C-HDMAPP is the pyrophosphonate form of (E)-HDMAPP. The pyrophosphonate moiety in (E)-C-HDMAPP is much less susceptible to chemical or enzymatic hydrolysis than its pyrophosphate counterpart. As a result, (E)-C-HDMAPP is much more stable in solution and in vascular circulation.{16651} (E)-C-HDMAPP possesses comparable activity to (E)-HDMAPP, which is the most potent of the isoprenoid phosphoantigens. (E)-C-HDMAPP stimulates the synthesis of tumor necrosis factor (TNF-?) by ??-T lymphocytes with an IC50 value of 0.91 nM.{16651} (E)-C-HDMAPP also significantly increases the number of circulating ??-T cells in vivo, in cynomolgus monkeys.{16651}
