产品描述

2,5-dimethyl Celecoxib is a derivative of celecoxib that does not inhibit COX-2 (IC50 = >100 μM).1 It does inhibit microsomal prostaglandin E synthase-1 (mPGES-1) in HeLa cells (IC50 = 15.6 μM) and reduces prostaglandin E2 production in HeLa, A549, and HCA-7 cells (IC50s = 0.64, 0.83, and 3.08 μM, respectively).2 It inhibits proliferation of drug-sensitive RPMI8226 and multidrug-resistant 8226/Dox40 multiple myeloma cells, as well as increases the rate of apoptosis when used at concentrations of 20 and 30 μM.3 2,5-dimethyl Celecoxib reduces the expression of survivin, cyclin A, cyclin B, MEK1, and MEK2 in 8226/Dox40 cells. The antiproliferative effect of 2,5-dimethyl celecoxib is independent of mPGES-1 inhibition.2

2,5-dimethyl Celecoxib induces apoptosis and autophagy via activation of ROS/JNK axis in nasopharyngeal carcinoma cells

Aging (Albany NY) 2021 Sep 12;13(17):21483-21496.PMID:34511433DOI:10.18632/aging.203488.

2,5-dimethyl Celecoxib (DMC), a close derivative of celecoxib, has also been reported to have anticancer effects. However, the effects and underlying molecular mechanisms of DMC with respect to nasopharyngeal carcinoma are still largely unknown. In this study, we present that DMC has displayed anticancer potency in nasopharyngeal carcinoma in vitro and in vivo. Mechanistically, we found DMC induced apoptosis and autophagy for anticancer therapy against nasopharyngeal carcinoma. Furthermore, DMC-induced autophagy could remarkably attenuate after the treatment of reactive oxygen species (ROS) scavenger N-acetyl cysteine (NAC) and c-Jun N-terminal kinase (JNK) inhibitor SP600125 (SP). Taken together, these results suggested DMC induced apoptosis and autophagic death via activation of ROS/JNK axis in NPC cells, which providing us new insights into developing potential therapeutic agents for nasopharyngeal carcinoma patients.

2,5-dimethyl Celecoxib Inhibits Proliferation and Cell Cycle and Induces Apoptosis in Glioblastoma by Suppressing CIP2A/PP2A/Akt Signaling Axis

J Mol Neurosci 2021 Aug;71(8):1703-1713.PMID:33400072DOI:10.1007/s12031-020-01773-8.

2,5-Dimethyl-celecoxib (DMC) is a close structural analog of the selective COX-2 inhibitor celecoxib that lacks COX-2-inhibitory function. Thus, DMC is a promising drug for anti-tumor. In this study, we evaluated the efficacy and the molecular basis of DMC in the treatment of human glioblastoma multiforme (GBM). DMC inhibited the growth and proliferation of GBM cell lines (LN229, A172, U251, and U87MG) in a dose-dependent manner (P < 0.001). In GBM cells treated with DMC, detection by flow cytometry showed cell cycle arrest, and proteins involved in cell cycle such as P21 were increased. Compared with control group, Annexin-V/PI-staining in DMC-treatment group was increased, indicating that DMC could induce apoptosis in GBM cells. Also, associated proteins including cleaved caspase 3 and cleaved PARP-1 were increased. It was further explored whether DMC blocked cell cycle and induced apoptosis in GBM cells through CIP2A/PP2A/AKT signaling pathway. After treatment of DMC, the phosphorylation of Akt was reduced while the total Akt level was not affected. DMC suppressed the expression of CIP2A in a time-dependent manner, while the CIP2A overexpression group reversed cell cycle and apoptotic protein expression led by DMC. Finally, in a xenograft model in nude mice using LN229 cells, DMC suppressed tumor growth. These findings proved that DMC could block cell cycle and induce apoptosis in GBM cells by suppressing CIP2A/PP2A/Akt signaling axis, which indicated that DMC could be an effective option for GBM treatment.

Enhancement of photodynamic therapy by 2,5-dimethyl Celecoxib, a non-cyclooxygenase-2 inhibitor analog of celecoxib

Cancer Lett 2011 May 1;304(1):33-40.PMID:21339042DOI:10.1016/j.canlet.2011.01.023.

Photodynamic therapy (PDT) effectiveness can be improved by employing combined modality approaches involving pharmaceuticals targeting the tumor microenvironment and/or tumor cell death pathways. In one approach, combining PDT with celecoxib improves long-term tumoricidal activity without increasing normal tissue photosensitization. However, side effects arising from the use of coxib based cyclooxygenase-2 (COX-2) inhibitors, including cardiovascular injury, decreases the clinical applications of this class of compounds. A growing number of studies demonstrate that the tumoricidal actions of coxibs such as celecoxib involve non-COX-2 mediated mechanisms. The celecoxib analog, 2,5-dimethyl Celecoxib (DMC), lacks COX-2 inhibitory activity but exhibits cytotoxic properties comparable to the COX-2 inhibitor celecoxib. We compared the effectiveness of DMC and celecoxib in modulating PDT response at both the in vitro and in vivo level using a C3H/BA murine mammary carcinoma model. Both DMC and celecoxib blocked PDT induced expression of the pro-survival protein survivin, enhanced the endoplasmic reticulum stress (ERS) response of PDT, and increased both apoptosis and cytotoxicity in BA cells exposed to combination protocols. DMC enhanced the in vivo tumoricidal responsiveness of PDT without altering PGE2 levels. Our data demonstrates that DMC improved PDT by increasing apoptosis and tumoricidal activity without modulating COX-2 catalytic activity. Our results also suggest that celecoxib mediated enhancement of PDT may involve both COX-2 dependent and independent mechanisms.

Dimethyl celecoxib as a novel non-cyclooxygenase 2 therapy in the treatment of non-small cell lung cancer

J Thorac Cardiovasc Surg 2005 Nov;130(5):1406-12.PMID:16256796DOI:10.1016/j.jtcvs.2005.07.018.

Objectives: The cyclooxygenase 2 enzyme has become a therapeutic target in cancer treatment. Cyclooxygenase 2 blockade with selective inhibitors increases apoptosis and decreases the metastatic potential of lung cancer cells. Some of the antitumor effects of these inhibitors may occur through both cyclooxygenase 2-dependent and independent pathways. Our goal was to investigate these pathways using celecoxib (selective cyclooxygenase 2 inhibitor) and 2,5-dimethyl Celecoxib, a structural analog modified to eliminate cyclooxygenase 2 inhibitory activity, while potentially maintaining antineoplastic properties. Methods: 2,5-dimethyl Celecoxib was synthesized in the Department of Chemistry at the University of Southern California. With the use of non-small cell lung cancer cells (A549), prostaglandin E2 production was quantified by enzyme-linked immunosorbent assay to assess cyclooxygenase 2 activity. Cell proliferation was assessed by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt assay. Cell migration was performed using transwell inserts that were matrigel coated for invasion experiments. Gelatin zymography was used to assess matrix-metalloproteinase activity. Results: 2,5-dimethyl Celecoxib did not inhibit interleukin-1beta-stimulated prostaglandin E2 production, whereas celecoxib did even at low doses. Both celecoxib and 2,5-dimethyl Celecoxib decreased tumor cell viability and proliferation with IC50 for celecoxib and 2,5-dimethyl Celecoxib of 73 and 53 micromol/L, respectively. Both drugs were also potent inducers of apoptosis, and both inhibited tumor cell migration and invasion. This was associated with down-regulation of matrix metalloproteinase activity. Conclusions: 2,5-dimethyl Celecoxib is a structural analog of celecoxib that lacks cyclooxygenase 2 inhibitory activity but exhibits significant antineoplastic properties comparable to celecoxib. This suggests that the antineoplastic activities of celecoxib are, at least in part, cyclooxygenase independent and that therapeutic strategies can be developed without the side effects of global cyclooxygenase 2 blockade.
