CGS 23885
CGS 23885 is an orally active 5-lipoxygenase (5-lipoxygenase) inhibitor. CGS 23885 reduces the production of 5-hydroxyeicosatetraenoic acid (5-hydroxyeicosatetraenoic acid), LTB4, and LTC4/D4/E4. CGS 23885 inhibits cell infiltration in rat pleurisy. CGS 23885 can be used in pleurisy-related research.

In Vitro
CGS 23885 (Compound 43) potently inhibits 5-lipoxygenase activity in guinea pig polymorphonuclear leukocytes (PMNs), with an IC50 value of 43 nM for the inhibition of 5-HETE production and an IC50 value of 48 nM for the inhibition of LTB4 production[1].
CGS 23885 weakly inhibits ram seminal vesicle cyclooxygenase with an IC50 of 36 μM, and exhibits high selectivity for 5-lipoxygenase[1].
CGS 23885 moderately inhibits human platelet 12-lipoxygenase with an IC50 of 0.64 μM[1].
CGS 23885 inhibits 5-lipoxygenase activity in canine whole blood with an IC50 of 0.11 μM[1].
CGS 23885 inhibits the activity of 5-lipoxygenase in human whole blood with an IC50 of 0.89 μM[1].

Animal Model:Sprague-Dawley rats (male, 220-235 g, pleurisy induced by intrapleural κ-carrageenan and calcium ionophore A23187)[2]
-
Dosage:1 mg/kg; 3 mg/kg; 10 mg/kg; 30 mg/kg
-
Administration:p.o.; 1 h before carrageenan injection and 1 h before A23187 injection
-
Result:Inhibited A23187-enhanced LTB4 biosynthesis by 32% and LTC4/D4/E4 biosynthesis by 4% at 1 mg/kg.
Inhibited A23187-enhanced LTB4 biosynthesis by 73% and LTC4/D4/E4 biosynthesis by 33-35% at 3 mg/kg.
Inhibited A23187-enhanced LTB4 biosynthesis by 93% and LTC4/D4/E4 biosynthesis by 52-67% at 10 mg/kg.
Inhibited A23187-enhanced LTB4 biosynthesis by 97% and caused a 24% significant reduction in total cellular influx at 30 mg/kg.
Showed a positive correlation between pleural fluid concentration and inhibition of LTB4 biosynthesis, with an IC50 of 21 ng/mL for LTB4 inhibition.
Produced no significant effect on exudate volume, PGE2 levels, or TXB2 levels at all doses; no significant effect on total cellular influx at 1, 3, 10 mg/kg.
