The regulation of would healing is one of the most important fields of research in ophthalmology today. Rabbit corneal fibroblast cultures were used to study the effects of interleukin-1 (IL-1) blockers on the proliferation of fibroblasts which is closely related to the wound healing. It was found that IL-1 blockers, such as CK-17, CK-101A, CK-2 and CK-103A, suppress fibroblast proliferation in a concentration-dependent manner. DNA synthesis was significantly inhibited by CK-17 and CK-103A but not by CK-101A and CK1-102. Although the synthesis of mRNA was reduced by all CK-compounds at most concentration tested, the synthesis of protein was only slightly reduced or unaffected. These results indicate that CK-compounds are potent fibroblast inhibitors but not cytolytic agents.
