Effects of ether lipid 1-O-octadecyl-2-methoxy-rac-glycero- 3-phosphocholine and its analogs PAF and CPAF on the release of nitric oxide in primary cultures of rat astrocytes.
Ether lipid 1-O-octadecyl-2-O-methoxy-rac-glicero-3-phosphocholine (ET-18-OCH3) is an immunomodulator with antineoplastic activity. Its analog compounds PAF and CPAF share some of its biological effects. In our experiments, even very small amounts of ET-18-OCH3 released a remarkable quantity of nitric oxide (NO) from rat astrocytes cultured in vitro. The NO biosynthesis was inhibited by pretreatment with the antagonist BN 50730. The effect of ET-18-OCH3 was greater than that of the LPS inducer. PAF did not produce NO, even at high doses, while the nonmetabolizable CPAF only induced a significant release of NO from 12 micrograms/ml onwards. These results demonstrate that ET-18-OCH3 is functionally active also in astrocyte cultures. Stimulation of NO biosynthesis is of a great value on account of its the known effect as a neurotransmitter, potentiator of immune defences and possible modulator of cerebral circulation.

The effect of ether lipid 1-O-octadecyl-2-O-methoxy-rac-glycero-3-phosphocholine and its analogues platelet activating factor and carbamyl-platelet activating factor on the biosynthesis of interleukin-6 in human thymic epithelial cells cultivated in vitro
The effect of ether lipid 1-O-Octadecyl-2-O-methoxy-rac-glycero-3-phosphocholine (ET-18-OCH3), platelet activating factor (PAF) and carbamyl activating factor (CPAF) on the release of IL-6 in human thymic epithelium cultivated in vitro was studied. ET-18-OCH3 significantly increased the release of IL-6, giving the greatest effect at the dose of 2 micrograms/ml. PAF had no effect. The non-metabolizable CPAF was less effective than ET-18-OCH3 and showed the greatest release of IL-6 at the dose of 1 microgram/ml. Ether lipid ET-18-OCH3 has a thymotrophic effect as has also been demonstrated by other results obtained in our previous work.
