光谱分析揭示HOMO-LUMO跃迁主导其紫外-可见吸收（260–345 nm），理论计算表明B环3'-OH位点反应性最强，氢键作用影响BDE值。分子对接筛选出橙皮素（hesperetin）等5种潜在MAO-B抑制剂，为天然抗氧化剂开发提供新思路。 七种黄酮类化合物（flavanones）通过计算模拟评估 ...

Summary: Rasagiline is a novel, investigational propargylamine that irreversibly and selectively inhibits monoamine oxidase type B (MAO-B). Rasagiline demonstrates complete and selective ...

Specifically, 3-phenyl substitution in coumarin derivatives significantly enhanced MAO-B inhibition and increased selectivity for MAO-A, while 4-phenyl substitution is more effective for MAO-A ...
