- W2999362938 abstract "Betti bases (aminobenzylnaphthols) have not been studied extensively to explore their possible pharmacological applications. Our group prepared a small and focused library of twenty-three Betti bases from the multicomponent reaction of 2-naphthol with primary or secondary cyclic amines and representative aromatic aldehydes. The compounds were prepared in 52-90% yield using environmentally friendly procedures. The E-factor and the atom economy for our process were 3.92 and 94%, respectively. The study of the anti-proliferative activity against human solid tumor cell lines pointed out that these Betti bases represent privileged scaffolds and could be used for the development of pharmacologically-active compounds in cancer therapeutics. The 50% growth inhibitory (GI50) values of the most potent compounds were in the low micromolar range. Fourteen of these Betti bases were less active in HBL-100 breast cancer cells than towards the breast cancer cell line T-47D. A subset of these Betti bases was further tested against the human breast cancer cell lines MCF-7 and MDA-MB-453. The results indicated a correlation in the sensitivity of T-47D cells to Betti bases. We explored computationally the interaction of the Betti bases with SLC6A14, a Na+- and Cl-- dependent influx transporter of both neutral and cationic amino acids that is overexpressed in T-47D cells. SLC6A14 is inhibited by α-methyl-tryptophan, which blocks cell growth via deprivation of amino acid influx. The docking studies indicated that our Betti bases might behave as tryptophan mimetics, blocking this solute carrier transporter and inducing the anti-proliferative effects. Importantly, these Betti bases showed good cytotoxic selectivity towards cancer cells with no activity against normal human fibroblast cells BJ-hTERT." @default.
