Cyclic phosphatidic acid (cPA) is a naturally occurring phospholipid mediator possessing cyclic phosphate ring, which is necessary for its specific biological activities. To stabilize cyclic phosphate ring of cPA, we synthesized a series of cPA derivatives. We have shown that racemic 3-S-cPA, with a phosphate oxygen atom replaced with a sulfur atom at the sn-3, was a more effective autotaxin (ATX) inhibitor than cPA. In this study, we showed that racemic 3-S-cPA also had potent biological activities such as inhibition of cancer cell migration, suppression of the nociceptive reflex, and attenuation of ischemia-induced delayed neuronal cell death in the hippocampal CA1. Moreover, we synthesized both enantiomers of palmitoleoyl derivative of 3-S-cPA, and found that the chirality of 3-S-cPA is not involved in ATX inhibition. Based on these findings, racemic 3-S-cPA is suggested as an effective therapeutic compound like cPA. (C) 2012 Elsevier Ltd. All rights reserved.
