Pidotimod是一种合成的二肽分子，对适应性和先天性免疫反应都有生物学免疫活性。对动物和人的样本进行体外研究发现Pidotimod对适应性和先天性免疫反应都有很好的活性，这一结论也在体内实验中得到了确认。这些活性已经应用到临床，在减轻儿童上呼吸道和尿道感染复发率上效果良好。在成人呼吸道感染复发的抑制上也有同样效果A synthetic dipeptide with immunological modulatory activity on both the adaptive and innate immune responses. Pidotimod is an immunostimulant.Pidotimod is a synthetic dipeptide molecule with biological and immunological activity on both the adaptive and the innate immune responses. In vitro studies, both from animal and human specimens, have documented a good activity on innate and adaptive immune responses and have been confirmed by in vivo studies. These activities have been applied in clinical studies demonstrating the efficacy of pidotimod in reducing the rate of recurrent infections of the upper respiratory and urinary tracts in children. The same results are obtained in recurrent respiratory tract infections in adults. A synthetic dipeptide with immunological modulatory activity on both the adaptive and innate immune responses.
