Erbstatin, a tyrosine kinase inhibitor, inhibited p59fyn- and p56lck-kinases in vitrowith IC50s of 0.21 and 0.18μg/ml, respectively. Inositol phosphates formation, enhanced by anti-CD3, was also inhibited by erbstatin. Moreover, erbstatin treatment prevented anti-CD3-induced interleukin 2 (IL-2) production, but phorbol ester-induced IL-2 production was not affected by erbstatin.
