The anti-inflammatory effects of lactic acid derivatives were investigated on ultraviolet B (UVB)-irradiated HaCaT human keratinocytes. A pretreatment with indole-3-lactic acid (ILA) and 4-hydroxyphenyllactic acid (HPLA) inhibited the UVB-induced production of interlekin-6 (IL-6). The inhibitory effect of L-HPLA was equivalent to that of a corresponding racemic mixture (DL-HPLA), suggesting that optical isomerism did not affect the anti-inflammatory activity of HPLA.
