Effect of IKK-2 inhibitor on local Th1 and Th2 type inflammation.

We studied the capacity of IKK-2 inhibitor ([5-(p-fluorophenyl)-2-ureido] thiophene-3-carboxamide) and non-steroidal anti-inflammatory drug voltaren to reduce the severity of local inflammation in Th1- and Th2-type immune response. The test substances (inhibitor in concentrations from 2×10(-13)to 2×10(-16)M and 9.8×10(-4)M voltaren) were shown to reduce edema caused by sheep erythrocytes (Th1-type immune response) and local immediate-type hypersensitivity response (Th2-type immune response). The anti-inflammatory effects of IKK-2 inhibitor in Th1-type immune response were similar to those of voltaren.
