Arylpyridines, arylpyrimidines and related compounds as potential modulator agents of the VEGF, hTERT and c-Myc oncogenes.
2019
Twenty-four derivatives structurally related to honokiol have been synthesized and biologically evaluated. IC50 values were determined towards the HT-29, MCF-7 and HEK-293 cell lines. Some of these derivatives exhibited comparable or lower IC50 values than honokiol towards the HT-29 and MCF-7 cell lines or else higher selectivity indexes than the natural product. Twelve selected derivatives were evaluated for their ability to inhibit the expression of the VEGFA, hTERT and c-Myc genes and also to inhibit the production of total c-Myc protein and the secretion of the VEGF protein. One of the most promising compounds, 3-(2,4-dimethoxyphenyl)pyridine, may be a good candidate for further studies…
Synthesis of honokiol analogues and evaluation of their modulating action on VEGF protein secretion and telomerase-related gene expressions
2017
A group of 36 biphenyl derivatives structurally related to honokiol were synthesized by means of Suzuki coupling reactions. Their cytotoxicities were evaluated and compared to that of honokiol. Some of the compounds were then evaluated for their ability to downregulate the secretion of the VEGF protein and the expression of the VEGF, hTERT, and c-Myc genes; the two latter involved in the activation of telomerase in tumoral cells. Some of the synthetized derivatives showed promising pharmacological features as they exhibited IC50 values in low micromolar range, good therapeutic margins, and a multiple mode of action on tumor cells based on the inhibition of VEGF and, at the same time, of the…
