Abstract: | he interest in the prostaglandin (PG) synthesis by animal cells today grows steadily because of the difficulties in obtaining
them by any other way. Murine peritoneal macrophages can under certain con ditions synthesize large amounts of PGs. The effect
of well-known nonsteroidal anti-inflammatory drug ibuprofen on PG synthesis by the cells using a high-performance liquid chromatography
(HPLC) method with fluorescence detection of 4-bromomethyl-7-methoxy coumarin (BrMMC) derivatives was studied. In our case,
the main metabolites were PGE2 and PGF2a. The PG synthesis activation effect was shown by ibuprofen concentrations in the 10-10-10-14M range with the maximum effect at the 10-12M. In this case, the ibupro fen effect was comparable in value with the effect of the well-known cell PG synthesis activator—calcium
ionophore A23187.
Although the exact mechanism of such an effect is not clear at the moment, at low concentration, ibuprofen itself is able
to activiate PG synthesis in murine peritoneal macrophages. |
