Methylcarbamyl PAF C-16 is a stable analog of PAF C-16 with a half-life greater than 100 minutes in platelet poor plasma due to its resistance to degradation by PAF-AH. It is nearly equipotent with PAF C-16 in its ability to induce platelet aggregation both in isolated platelets and in platelet-rich plasma. In...

PAF C-16 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the "remodeling" and 'de novo' pathways. It is a potent mediator of neutrophil migration, and the production of reactive oxygen species, and IL-6 in human macrophages. It is a more potent mediator of...

PAF C-18 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the "remodeling" and 'de novo' pathways. It is less potent than PAF C-16 in the induction of platelet aggregation, but equipotent in activation of guinea pig macrophages. PAF C-18 induces the release of...

Hexadecyl acetyl glycerol (HAG) is an analog of DAG, which inhibits the activation of PKC by DAG. It also inhibits the growth of HL-60 cells and induces differentiation to cells resembling mononuclear phagocytes. Following treatment with 5 µg/ml HAG for six days, HL-60 cells demonstrated a 10-fold increase in...
