Common NameCPA(18:2(9Z,12Z)/0:0)
DescriptioncPA(18:2(9Z,12Z)/0:0) is a cyclic phosphatidic acid or cyclic lysophosphatidic acid. It is a glycerophospholipid in which a cyclic phosphate moiety occupies two glycerol substitution sites. Lysophosphatidic acids can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1). Fatty acids containing 16 and 18 carbons are the most common. Cyclic phosphatidic acids have been detected in a wide range of organisms including humans, especially in the brain but also in serum (at a concentration of 10-7M). cPA's have a cyclic phosphate at the sn-2 and sn-3 positions of the glycerol carbons, and this structure is absolutely necessary for their activities. In particular, it is found in tissues subject to injury, and while it may have some similar signalling functions to lysophosphatidic acid per se, it also has some quite distinct biological activities. For example, cyclic phosphatidic acid is known to be a specific inhibitor of DNA polymerase alpha. It has an appreciable effect on the inhibition of cancer cell invasion and metastasis.
