Licofelone是一种 COX/LOX 双重抑制剂，IC50分别为 0.21和0.18 μM，有潜力研究骨关节炎，具有抗炎和抗增殖作用。它可诱导细胞凋亡，减少促炎性白三烯和前列腺素的产生。

Licofelone is a dual COX/LOX inhibitor potentially for the treatment of osteoarthritis. Licofelone is both an analgesic and an anti-inflammatory. Inhibition of 5-LOX may reduce the gastrointestinal toxicity associated with other non-steroidal anti-inflammatory drugs, which only inhibit COX (cyclooxygenase).

The dual COX/5-LOX inhibitor licofelone triggers apoptosis in a dose- and time-dependent manner in HCA-7 colon cancer cells.?Induction of apoptosis was related to the recruitment of the intrinsic mitochondrial apoptotic pathway, as shown by loss in mitochondrial membrane potential, cytochrome c release, caspase-9 and 3 activation and poly-(ADP-ribose)polymerase-1 cleavage.?Moreover, licofelone induced the cleavage of the full-length p21(Bax) into p18(Bax), a more potent inducer of the apoptotic process than the uncleaved form.?Pre-treatment of HCA-7 cells with the pan-caspase inhibitor z-VAD-fmk significantly blocked licofelone-induced apoptosis, confirming that this process occurred primarily in a caspase-dependent pathway.?Licofelone was able to affect the arachidonic acid (AA) cascade, as it blocked the activity of 5-LOX and COX enzymes, and it induced, through the phosphorylation of cytoplasmic phospholipase A(2) (cPLA(2)), the release of unesterified AA from HCA-7 membrane phospholipids.[1]
