摘要

Eleven novel C-16 triazole-fused isosteviol derivatives 6a–6k were synthesized by “Huisgen-click” 1,3-dipolar cycloaddition reaction. The structures of synthesized compounds were characterized by IR, NMR, and HR-MS spectra, respectively. Furthermore, the anti-LSD1 activity of compounds was investigated, after which the results revealed that compound 6h exhibited the best inhibitory activity with an IC50 value of 8.944 ± 1.013 μM. The structure–activity relationships were further analyzed to guide the future design of novel isosteviol derivatives with enhanced LSD1 inhibitory capabilities.
