Anti-uveitis and inhibition of fibroblast-like corneal and conjunctival cells by interleukin-1 blockers

Effects of interleukin-1 (IL-1) blockers, CK130 and CK131, on IL-1-induced uveitis and proliferation of fibroblast-like corneal and conjunctival cells were investigated in this study. It was found that CK130 and CK131 inhibited IL-1-induced uveitis in rat eyes effectively at 3 mg/kg and 10 mg/kg, respectively. Further, CK130 and CK131 inhibited fibroblast-like corneal and conjunctival cell growth effectively at 10–300 μg/ml and 30–300 μg/ml, respectively. It was also found that DNA synthesis was markedly reduced by CK130 and CK131 at 30–100 μg/ml. RNA synthesis was also inhibited by these CK compounds but protein synthesis was little affected or enhanced.
