Abstract

The present disclosure describes an oligobenzamide-based peptidomimetic agent with potent antiproliferative activity against triple negative breast cancer (TNBC), including TNBC cells representing all the known molecular subtypes. Lysosomal acid lipase A (LIPA) was identified as important for this agent's activity with the ER localization, not the lysosomal lipase function, of LIPA being critical. This agent can also block the growth in vitro and in vivo of multiple cancer types that have high basal level of ER stress and LIPA expression, including estrogen receptor-positive breast, pancreatic, glioblastoma and ovarian cancers. Thus, the inventors propose a new targeted strategy for TNBC and other rapidly proliferating cancers.
