General description

2,5-Dimethyl-celecoxib is a derivative of the anti-inflammatory drug, celecoxib.[1]

Application

2,5-Dimethyl-celecoxib may be used as an internal standard for the determination of celecoxib in human plasma samples by liquid chromatography coupled to electrospray ionization and time of flight mass spectrometry (LC-ESI-TOF-MS).[2]
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem/physiol Actions

Celecoxib analog devoid of COX-2 inhibitor activity, induces apoptosis by inhibiting expression of survivin.
Celecoxib, and the inactive analog 2′,5′-dimethyl celecoxib both induce apoptosis in a many cancer cell lines by down-regulating the expression of survivin. This activiy is mediated via an AKT mediated pathway, and is unique to this class of cyclo-oxygenase inhibitors, as non-selective NSAIDs or other COX-2 specific inhibitors such as rofecoxib, do not effect survivin expression. Unlike celecoxib, 2′,5′-dimethyl celecoxib is devoid of any inhibitory activity against COX-2.

Endoplasmic reticulum (ER) calcium homeostasis is disrupted in diverse pathologies, including neurodegeneration, cardiovascular diseases, and diabetes. Temporally defining calcium dysregulation during disease progression, however, has been challenging. Here we describe secreted ER calcium-monitoring proteins (SERCaMPs), which allow for longitudinal monitoring
