Abstract: Objective The aim of this study was to identify small-molecule drugs that inhibit neomycin-induced hair-cell-like cell(HEI-OC1)death, and to verify their effects on hair cells in cochlear explants and the lateral line of zebrafish. Methods Small-molecule drugs that increased the viability of HEI-OC1 cells were identified using Cell Counting Kit-8. The protective effect of the identified small-molecule drugs was verified in hair cells of cochlear explants and zebrafish by Immunofluorescence staining. Results Of the 350 small-molecule drugs screened, clomipramine hydrochloride was found to significantly improve the survival rate of neomycin-treated HEI-OC1 cells. In addition, clomipramine hydrochloride was found to have a protective effect on hair cells of neomycin-treated mouse cochlear explants and the lateral line of zebrafish. Conclusion Clomipramine hydrochloride, which as an FDA-approved clinical drug, has a protective effect against neomycin-induced hair cell damage.
