• The abietane natural products have been identified as potential leads against breast cancer.
• A focused-compound library based on the abietane molecular scaffold was synthesized.
• A promising compound lead against the triple-negative breast cancer was investigated.
Breast cancer remains the leading cause of cancer-related death among women. The invasive triple-negative subtype is unresponsive to estrogen therapy, and few effective treatments are available. In search of new chemical scaffolds to target this disease, we conducted a phenotypic screen against the human breast carcinoma cell lines MDA-MB-231, MA11, and MCF-7 using terrestrial natural products. Natural products that preferentially inhibited proliferation of triple-negative MDA-MB-231 cells over estrogen receptor–positive cells were further studied; herein we focused on the abietanes. The activity of the abietane carnosol prompted us to generate a focus library from the readily available (+)-dehydroabietylamine. The lead compound 61 displayed a promising EC50 of 9.0 μM against MDA-MB-231 and our mechanistic studies indicate it induced apoptosis, which was associated with activation of caspase-9 and -3 and the cleavage of PARP. Here we describe our current progress towards this promising therapeutic candidate.
