2-O-methyl PAF C-16 is a synthetic PAF analog which contains a methyl group, attached by an ether linkage, at the sn-2 position. Although the biological activities of 2-O-methyl PAF C-16 have not been well characterized, the C-18 analog has been shown to mediate a number of biological responses including decreasing plasma membrane fluidity and inhibiting tumor cell invasiveness in embryonic chick heart. In rat astrocytes, the C-18 analog causes the release of large quantities of NO by a pathway involving activation of NOS.
2-O-Methyl PAF C-16 (ET-18-O-OCH3), a structural analog of the mediator of inflammation platelet-activating factor (PAF), is a cytotoxic ether lipid. 2-O-Methyl PAF C-16 stimulates TNF-α release in murine macrophages[1].
