| Research Abstract |
Tight Junction is a sealing structure in the closely associated area of two adjacent cells located in epithelium of skin, intestine and so on. TJ functions not only a impermeable barrier to bacteria and exogeneous toxins, but also to medical drug, especially biomedicines. Therefore, it is required for injection or the other invasive methods to give medication the biomedicines to patients. However, if we have a compound which open the TJ transiently, it would be possible to give the orally or percutaneous medication.
Therefore, we constructed the two screening systems, and screened the compounds which open the TJ transiently. We successfully obtained one compound.
