Description

Tolmetin is an orally active and potent COX inhibitor with IC50s of 0.35 µM and 0.82 µM human COX-1 and COX-2, respectively. Tolmetin is a non-steroidal anti-inflammatory drug (NSAID)[1][2].

IC50 & Target[1]

Human COX-1

0.35 μM (IC50)

Human COX-2

0.82 μM (IC50)

In Vitro

Tolmetin (0.25 mM) does not attenuate lipid peroxidation in rat brain homogenate. Tolmetin (0.25, 0.5, 0.75, 1 mM) shows radical scavenging properties but without superoxide anion generation in rat brain homogenat[3].
Tolmetin (0.001-100 μM) shows anticancer activity againts HT-29 colon cancer cell line in a dose-dependent manner[4].
Tolmetin (0-100 μM) shows no effect on osteoblast growth[5].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo

Tolmetin (30,100 mg/kg; gavage; single dose or twice daily for 3 and 14 days) shows maximal ulcerogenic effect 4 h after the single dose, while potently decreases after 3 and 14 days of repeated administration in male Wistar rats weighing 180-200 g. Tolmetin causes gastric lesions in 100 mg/kg[2].
Tolmetin (5 mg/kg twice a day for 5 days) pre-treatment considerably attenuates quinolinic acid (QA)-induced neurotoxicity[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
