OBJECTIVE
The protein kinase C (PKC) family of serine-threonine kinases plays an important role in cancer cell progression. Thus, molecules that target PKC have potential as anticancer agents. The current study aims to understand the treatment of breast cancer cells with alkyl cinnamates. We have

Encouraging selectivity and low micromolar activity against HeLa cervical carcinoma (IC50⩾3.0μM) and the aggressive MDA-MB-231 triple negative breast carcinoma (IC50⩾9.6μM) cell lines has been exhibited by a number of readily accessible 4-(N-benzylamino)cinnamate esters. The potential of the ligands
