Description
KIAA1363 is a 2-
acetyl monoacylglyceryl ether (MAGE) hydrolase that is upregulated in aggressive cancers from various tissues.
1 The enzyme catalyzes the hydrolysis of the 2-
acetyl MAGE to MAGE and serves as a central enzyme in the PAF and LPA signaling network.
2 AS 115 is a potent and selective inactivator of KIAA1363, displaying an IC
50 value of 150 nM when tested as a racemic mixture in the invasive ovarian cancer cell line SKOV3.
2 Treatment of SKOV3 cells with 10 μM AS-
115 for 4 hours significantly reduced the formation of MAGE, alkyl-
lysophosphatidylcholine, and alkyl-
lysophosphatidic acid. The activity of the individual enantiomers of AS 115,
i.e. (+)-
AS 115 and (?)-
AS 115, has not been determined.
