Triple-Negative Breast Cancer (TNBC)

Allosteric EGFR inhibitor targeting dimerization interface

PCL-TNBC-009 is a novel allosteric EGFR inhibitor designed for triple-negative breast cancer. It features a 2-aminopyrimidine core linked via a benzamide bridge to an N-methylpiperazine moiety for improved solubility. The molecule passes all Lipinski and Veber criteria with zero PAINS alerts. ML models flag moderate hERG and high DILI risk, suggesting the carboxamide linker may need optimization. ChEMBL similarity analysis reveals structural kinship to imatinib-class kinase inhibitors, supporting the proposed mechanism.
