Synthesis and PGE2 production inhibition of s-triazine derivatives as a novel scaffold in RAW 264.7 macrophage cells
摘要:
We present the synthesis and biological evaluation of a collection of s-triazine derivatives as a novel scaffold of compounds with the capability to inhibit the PGE(2) production in LPS-induced RAW 264.7 macrophage cells. A total of 12 derivatives were synthesized and assayed for PGE(2) reduction at 10 mu M concentration. Two compounds (7b and 7i) exhibiting >90% inhibition of PGE(2) production were found to have IC50 values of 5.76 and 5.52 mu M, respectively. They were counter screened for inhibition on COX-2 activity in a cell free assay. Specifically, compound 7i (R-1 = 4-Bn-Ph, R-2 = Cl, R-3 = Ph, R-5 = CO2Me) was highly active in cells while maintaining little COX-2 inhibition (similar to 0% at 10 mu M). Molecular docking study provides the possibility that compound 7i could inhibit PGE(2) production by blocking the PGH(2) binding site of mPGES-1 instead of COX-2 enzyme. Based on this result, our synthetic efforts will focus on intensive structure-activity relationship (SAR) study of s-triazine scaffold to discovery a potential PGE(2) synthesis inhibitor.

(EN) The use of triazine compounds of formula (I) for the preparation of a medicament for use in a method for defaunation of ruminant animals, in which an effective amount of the compound is administered to the animals. Defaunation is the selective removal of protozoa from the rumen in preference to removal or deactivation of bacteria. In formula (I): x = 1 or 2, R = H or lower alkyl, Ar = phenyl, diphenyl, naphthyl, anthracyl or phenanthryl radicals and substituted derivatives thereof.(FR) Utilisation de composés de triazine de la formule (I) pour la préparation d'un médicament utilisé dans un procédé de défaunation de ruminants, selon lequel une quantité efficace du composé est administrée aux animaux. La défaunation consiste à enlever de préférence sélectivement des protozoaires de la panse au lieu d'enlever ou de désactiver des bactéries. Dans la formule (I) x = 1 ou 2, R = H ou alkyle inférieur, Ar = radicaux de phényle, diphényle, naphtyle, anthracyle ou phénanthryle et dérivés substitués de ces radicaux.
