New thymol-3,4-disubstitutedthiazole hybrids were synthesised as dual COX-2/5-LOX inhibitors. Compounds , , , and displayed inhibitory activity against COX-2 (IC= 0.037, 0.042, 0.046, and 0.039 µM nearly equal to celecoxib (IC= 0.045 µM. , , and showed SI (379, 341, and 374, respectively) higher than that of celecoxib (327). - elicited 5-LOX inhibitory activity higher than quercetin. -, -, , and possessed inhibition of formalin induced paw edoema higher than celecoxib. , , , -, and showed gastrointestinal safety profile as celecoxib and diclofenac sodium in the population of fasted rats. Induced fit docking and molecular dynamics simulation predicted good fitting of and without changing the packing and globularity of the apo protein. In conclusion, and achieved the target goal as multitarget inhibitors of inflammation.

Ethnopharmacological Relevance: Traditional Chinese medicine (TCM) is frequently used to treat osteoarthritis (OA). Duhuo Jisheng decoction (DHJSD), a Chinese patent medicine, was commonly used Chinese herbal formula for the treatment of OA. In Western medicine, dual inhibition of cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) enzyme has been proved to be a promising strategy to treat inflammatory diseases with reduced side effects.

Cyclooxygenase (COX) and lipoxygenase (LOX) enzymes play a pivotal role in producing pro-inflammatory eicosanoids, including prostaglandins (PGs) and leukotrienes (LTs), in the inflammation process. Mitragynine is a primary alkaloid contained in the kratom's leaves and has been reported to show anti-inflammatory activity by suppressing COX-2 mRNA translation to lowering PGs synthesis. In this study, the Kratom's alkaloid extract containing ~ 46% mitragynine was found to exhibit dual inhibition activity towards COX-2/5-LOX enzymes at concentrations below 25 ppm in the LPS-induced RAW 264.

Piperazine derivatives were screened using the ChEMBL database, paving the way for the design, synthesis, and evaluation of a novel series of dual COX-2/5-LOX inhibitors and identifying their role in mitigating cancer cell proliferation. Compound 9d with 4-Cl substitution at the terminal phenyl ring showed promising inhibition of COX-2 (IC = 0.25 ± 0.

Background: Non-communicable diseases are chronic systemic inflammation in humans that occurs because of enhanced inflammatory mediators of the arachidonic acid cascade. We aimed to explore whether the lead chalcone compounds could exhibit anti-inflammatory activity via dual blockage of COX-2/5-LOX enzymes and their regulatory mechanism.
Methods: RAW 264.
