A series of 18 chrysin derivatives, prepared by alkylation and condensation, were fully characterized by NMR and other techniques and tested in vivo against the diabetes mellitus. Several modified compounds especially those with propyl, butyl, octyl and tolyl groups were found to have hypoglycemic effect on diabetec mice in spite of the fact that chrysin itself had inhibited insulin release by 40-60%. None of the test animals died at the maximum dose 500mg/kg and did not cause any significant change in general feature, water and food consumption, body weight and organ weight when we examined the acute oral toxicity of those compounds having significant hypoglycemic effect.

Twenty-three chrysin derivatives were designed and synthesized by alkylation and bromination reactions. Their structures were confirmed by NMR and mass spectrometry, and their in vitro ⍺-glucosidase (AG) inhibitory activity was investigated. Chrysin derivatives except for 3a, 3b, 2q, and 2r, revealed better activity than the reference acarbose with moderate to very strong inhibition against AG. Notably
通过烷基化和溴化反应设计合成了 23 种白杨素衍生物。通过核磁共振和质谱确定了它们的结构,并研究了它们的体外⍺-葡萄糖苷酶 (AG) 抑制活性。除3a、3b、2q和2r之外的白杨素衍生物显示出比参考阿卡波糖更好的活性,具有中度到非常强的 AG 抑制作用。值得注意的是,2f、2j和4对 AG ⍺-葡萄糖苷酶抑制活性表现出非常强的作用,IC 50值分别为 0.08、3.47 和 2.97 μM。同时,酶动力学研究表明2f为竞争型抑制剂,2j和4为混合型抑制剂。
