Herein, dose- and time-dependent in vitro anticancer activity studies of anti-inflammatory drugs, including celecoxib (C), indomethacin (I), and meloxicam (M), in combination with natural products (taxifolin (T), quercetin (Q), and rutin (R)) and doxorubicin (Dox), were carried out in MDA-MB-231, BT-20, MCF-7, and HT-29 human cancer cell lines. The obtained results highlight that drug C and T may be potential inhibitor candidates as SphK1 inhibitors for targeted cancer therapy. Overall, the combination of drug C with T has shown promising results, anticancer effects in breast and colon cancer cells and antiulcerative effects in rats.

In conclusion, this study shows that the combination of TQ with IR, Clx, or both exerts significant effects on SW620 colon cancer cells, such that by enhancing DNA damage, TQ may induce G2/M cell cycle arrest and apoptosis, while reducing inflammatory responses, oxidative stress, and G0/G1 cell cycle arrest. These in vitro findings indicate that TQ may enhance the chemotherapeutic effects of IR and act as a potential adjuvant therapy; however, further in vivo studies are required to verify its suggested effects.

COX-2 is a critical early-event biomarker and therapeutic target in colorectal adenomas. Targeting the COX-2 pathway represents a viable strategy for prevention, although challenges regarding safety and personalized application remain.

Rats were administered OANG (high/low dose) intra-articularly, with celecoxib as a positive control...Furthermore, OANG ameliorated hippocampal oxidative stress and inflammation (decreased Cleaved caspase-3, Malondialdehyde; increased IL-10). Network pharmacology and docking suggested the involvement of peroxisome proliferator-activated receptor gamma, mitogen-activated protein kinase 3, prostaglandin-endoperoxide synthase 2, and pathways such as estrogen signaling and cyclic adenosine monophosphate signaling.

This study investigates the in vitro antitumor properties and mechanism of action of novel vicinal diaryl-substituted heterocyclic COX-2 inhibitors, with a focus on VA1213, in comparison to celecoxib, a widely marketed COX-2 inhibitor known for its off-target effects...Its ability to interfere with multiple cancer-associated signaling pathways and reduce tumor cell aggressiveness underscores its potential as a promising therapeutic candidate. Further in vivo studies are warranted to confirm its efficacy and assess potential off-target effects.
