GSK1904529A, which potently inhibits IGF-IR and IR activities in vitro and in vivo, is a promising candidate for therapeutic use in solid and hematologic cancers.GSK1904529A selectively inhibits IGF-IR and IR with IC50s of 27 and 25 nmol/L, respectively.IC50s for GSK1904529A in tumor cell lines ranged from 35 nmol/L to >30 umol/L. The tumor histologic types showing the greatest sensitivity to this compound were Ewing's sarcoma and multiple myeloma, where IC50s in three of five Ewing's sarcoma cell lines were <100 nmol/L and IC50s in five of eight multiple myeloma cell lines were <200 nmol/L.Oral administration of GSK1904529A decreases the growth of human tumor xenografts in mice.
