Wy-41,195 demonstrated significant inhibitory effects (54-60%) when administered topically at 0.25-2% concentrations in a rat passive eyelid anaphylaxis assay. In contrast, topically applied disodium cromoglycate (DSCG) showed non significant inhibition at these concentrations. The potency of Wy-41,195 was more than 8 times greater than DSCG, and this compound may be an effective topical agent in man in preventing allergic and associated conditions.
