| Hazard Information | Back Directory | [Uses]
KX1-004 is a potent and non-ATP competitive Src-PTK inhibitor with an IC50 of 40 μM. KX1-004 protects the cochlea from hazardous noise and prevents noise-induced hearing loss (NIHL)[1][2]. | [Biological Activity]
kx1-004 is a non-atp competitive inhibitor of pp60c-src with ic50 value of 40 μm [1].kx1-004 is a close analog of the indole-based src-ptk inhibitors reported previously. it has a 5-fluoro group and showed potent inhibition activity in isolated src-ptk assay. kx1-004 was found to have protective effect in noise-induced hearing loss. the chinchillas treated with 30 μm kx1-004 were exposed to continuous noise. and the results showed that treated ears exhibited up to 40 db less threshold shift (tts) and up to 25 db less permanent threshold shift (pts) than control ears. kx1-004 treatment also significantly reduced outer hair cell (ohc) loss than control. besides that, kx1-004 was proved to reduce the hearing loss and hair cell loss associated with impulse noise exposure markedly [1, 2]. | [in vivo]
KX1-004 (30 μM) provides significant protection against noise-induced temporary threshold shift (TTS), permanent threshold shift (PTS) and outer hair cells (OHC) loss[1].
KX1-004 (50 mg/kg) is effective against noise exposure[2]. | [storage]
