Title: Evans Blue and other dyes as protein tyrosine phosphatase inhibitors.
Authors: Shrestha S, Shim YS, Kim KC, Lee KH, Cho H.
Abstract: Commonly used dyes including Evans Blue and Trypan Blue were examined for their inhibitory activities against protein tyrosine phosphatases (PTPases), all of them showed inhibition of PTPases with different potencies. Of the 13 dyes tested, four exhibited IC(50) value of less than 10 microM, Evans Blue lowest IC(50) of 1.3 microM against PTP1B. Care must be taken in the use of dyes for clinical or biochemical experiments to avoid unwanted side effects. Some of the low molecular weight dyes might be useful as lead compounds for the development of potent and selective PTPase inhibitors.
