Using an NMR-based screen, a series of novel phosphotyrosine mimetics were
discovered that bind to the SH2 domain of Lck. These compounds may serve as
useful leads for the design of nonpeptide inhibitors of SH2 domains with i
mproved bioavailability and metabolic stability compared to the natural lig
ands that contain phosphotyrosine. (C) 1999 Elsevier Science Ltd. All right
