Challenging inflammatory process at molecular, cellular and in vivo levels via some new pyrazolyl thiazolones.

Perihan A Elzahhar, Rana A Alaaeddine, Rasha Nassra, Azza Ismail, Hala F Labib, Mohamed G Temraz, Ahmed S F Belal, Ahmed F El-Yazbi,

The work reported herein describes the synthesis of a new series of anti-inflammatory pyrazolyl thiazolones. In addition to COX-2/15-LOX inhibition, these hybrids exerted their anti-inflammatory actions through novel mechanisms. The most active compounds possessed COX-2 inhibitory activities comparable to celecoxib (IC<sub>50</sub> values of 0.09-0.14 µM) with significant 15-LOX inhibitory activities (IC<sub>50</sub>s ...
