Twenty-three natural jamunone analogues along with a series of jamunone-based derivatives were synthesized and evaluated for their inhibitory effects against breast cancer (BC) MDA-MB-231 and MCF-7 cells. The preliminary structure-activity relationship revealed that the length of aliphatic side chain and free phenolic hydroxyl group at the scaffold played a vital role in anti-BC activities and the methyl group on chromanone affected the selectivity of molecules against MDA-MB-231 and MCF-7 cells. Among them, jamunone M (JM) was screened as the most effective anti-triple-negative breast cancer (anti-TNBC) candidate with a high selectivity against BC cells over normal human cells. Mechanistic investigations indicated that JM could induce mitochondria-mediated apoptosis and cause G0/G1 phase arrest in BC cells. Furthermore, JM significantly restrained tumor growth in MDA-MB-231 xenograft mice without apparent toxicity. Interestingly, JM could downregulate phosphatidylinositide 3-kinase (PI3K)/Akt pathway by suppressing protein-tyrosine phosphatase 1B (PTP1B) expression. These findings revealed the potential of JM as an appealing therapeutic drug candidate for TNBC.

The synthesis of the title compound 1e was achieved by an easy three-step procedure from 1,3,5-benzenetriol (1a, phloroglucinol).Compound 1a was C-methylated using MeI.The crude mixture obtained was acetylated to give 1d which was converted into 1e using BF3*AcOH complex.Benzylation of the latter with benzyl chloride afforded the new non-aromatic compound 2.Reaction of 2 with NaOH and benzoyl chloride (Scheme 1) gave the new compound 4.Its structure was established by X-ray analysis. - Keywords: Acetophenone / Di-C-methylphloracetopheneone
