Our lead compound for a phosphoinositide 3-kinase (PI3K) inhibitor (1) was metabolically unstable because of rapid glucuronidation of the phenol moiety. Based on structure-activity relationship (SAR) information and a FlexSIS docking simulation score, aminopyrimidine was identified as a bioisostere of phenol. An X-ray structure study revealed a hydrogen bonding pattern of aminopyrimidine derivatives. Finally, aminopyrimidine derivatives 33 showed strong tumor growth inhibition against a KPL-4 breast cancer xenograft model in vivo.
