COX-2-IN-55 (compound 1) is an orally active Celecoxib analogue with broad-spectrum anticancer properties and relatively weak COX-2 inhibition. It specifically inhibits SERCA2, leading to increased caspase-3 cleavage and DR5 levels, which activates GRP78 and suppresses the progression of triple-negative breast cancer (TNBC). Additionally, COX-2-IN-55 downregulates the angiogenesis markers VEGF-α and IL-8, thereby inhibiting microvessel formation.

| In vitro | COX-2-IN-55 (compound 1) inhibits the viability of MDA-MB-231, MDA-MB-468, 4T1, T47D, and MCF-7 cells, with EC50 values of 14.99 μM, 14.26 μM, 11.23 μM, 17.3 μM, and 25.02 μM, respectively. |
| In vivo | COX-2-IN-55, administered at 25 mg/kg/day and 50 mg/kg/day orally for 28 days, exhibits significant antitumor activity in the MDA-MB-231 xenograft model using nu/nu nude mice, achieving up to 85% tumor regression. At a dosage of 100 mg/kg/day, COX-2-IN-55 does not cause notable biochemical or histological toxicity in mice after 48 days of treatment. |
