Floctafenine

Floctafenine, a nonsteroidal anti-inflammatory agent (NSAID), acts as an effective analgesic agent^[1][2]. Floctafenine is an inhibitor of COX-1 and COX-2 activities in vitro,showing a slightly higher potency towards COX-I. Floctafenine is used for the research of short term pain treatment^[3]. In Vitro: Floctafenine (0.1-100 μM; in the presence of LPS; 24 hours) is slightly more potent 1.5-fold to inhibit in vitro platelet COX-I than monocyte COX-2. The IC₅₀ values for platelet COX-I and monocyte COX-2 inhibition are 2.33 μM (95%CI) and 3.47 μM (95%CI), respectively in heparinized whole blood samples^[3].
Floctafenine (0.1-100 μM; in the presence of A23187; 1 hour) does not significantly affect A23187-caused LTB4 generation even up to 100 μM^[3].
In Vivo: Floctafenine (intraperitoneal?injection; 50 mg/kg; single dose; 30 minutes prior to p-benzoquinone) has an inhibitory effects on p-benoquinone-induced writhing in rats, inhibition of writhing is 65.98%^[1].
