natural product-like polyprenylated phenols and quinones were synthesized and their neuroprotective activity was tested using human monoamine oxidase B (MAO-B) and SH-SY5Y cells. Eight compounds inhibited MAO-B (IC50 values < 25 μM) and the inhibition mode and molecular docking of two (8c and 16c) were investigated. Compounds inhibiting MAO-B activity were additionally tested for their ability to protect
合成了27种天然产物状的聚异戊二烯基酚和醌,并使用人单胺氧化酶B(MAO-B)和SH-SY5Y细胞测试了它们的神经保护活性。八种化合物抑制了MAO-B(IC50值<25μM),并研究了两种化合物(8c和16c)的抑制模式和分子对接。还测试了抑制MAO-B活性的化合物保护SH-SY5Y细胞免于过氧化物损伤的能力。三种衍生物(3c,8c和16c)同时具有MAO-B抑制和神经保护作用。结构活性关系研究表明,酚羟基和较长的侧链对于这两种活性都很重要。
