Thioflosulide  (Synonyms: L-745337)

Thioflosulide (L-745337) is a selective cyclooxygenase-2 (COX2) inhibitor, with an IC₅₀ of 2.3 nM, and shows anti-inflammatory activity.

In a rat model of postoperative pain, Thioflosulide (L-745337) (40-80 μg, intrathecal) coadministered with intrathecal morphine (0.5 nmol) increases the withdrawal thresholds in a dose-dependent manner. Adding 80 μg Thioflosulide (L-745337) to 1 nmol morphine produces an antiallodynic effect greater than that of morphine at twice the dose. Thioflosulide (L-745337) (0-30 mg/kg, s.c.) combined with intrathecal morphine results in the same antiallodynic response as morphine alone^[1]. Thioflosulide (L-745337) shows anti-inflammatory activity, with the effective-dose of 0.4 mg/kg, and the maximal anti-inflammation dose of 5 mg/kg in arthritic rats^[2].
