Phytochemicals like Lawsone have some drawbacks that stem from their poor solubility. Low solubility in aqueous mediums results in low bioavailability, poor permeability and instability of phytochemical compounds in biological environments. The aim of this study was to design nanoniosomes containing
Ru(ii)-Naphthoquinone complexes with high selectivity for triple-negative breast cancer.

Substituted lawsone Mannich bases 2a-e, 3a-e and 4a-e were prepared and tested for their biological activities. The new fatty alkyl substituted compounds 2a-c exhibited strong and selective growth inhibitory activities in the low one-digit micromolar and sub-micromolar range against a panel of human
