Abstract:
:Pyrazine-fused 23-hydroxybetulinic acid was synthesized by introducing a pyrazine ring between C-2 and C-3 position and further modifications were carried out by substitution of C-28 carboxyl group by ester and amide linkage to enhance the antitumor activity. The biological screening results showed that all of the derivatives exhibited more significant antiproliferative activity than the parent compound. In particular compound 12a exhibited the most potent activity with IC50 values of 3.53 μM, 4.42 μM and 5.13 μM against cell lines SF-763, B16 and Hela, respectively. In the preliminary mechanism study, 12a caused cell arrest in G1 phase and significantly induced apoptosis of B16 cells in a dose-dependent manner. Furthermore, the in vivo antitumor activity of 12a was validated (tumor inhibitory ratio of 55.6% and 62.7%, respectively) in mice with H22 liver cancer and B16 melanoma.
