Having identified 3 as the most active of the synthesised l-sugar analogues, its effects on the viability of additional cancer cell lines including BT549, MDA-MB-453, MDA-MB-468, and Hs578t (triple negative breast cancer lines), and BT474 (hormone receptor positive breast cancer cells) (Figure 3) was investigated. Here, NR4A1 is linked to triple-negative breast carcinoma.
