to be the most effective. Our study revealed that (−)-usnic acid exhibited higher antiviral activity than its (+)-enantiomer, but in the pairs of enantiomer derivatives such as enamines, pyrazoles and chalcones, the (+)-enantiomers were more potent inhibitors of the virus. For other groups of compounds the inhibiting activities of the enantiomers were comparable. Further optimization of the structure
流感病毒是严重的人类病原体,在世界范围内导致很高的发病率和死亡率。由于高突变率,它能够快速发展耐药性,这使得寻找具有广泛范围和替代靶标的新型抗病毒药成为必要。在本研究中,我们描述了松萝酸(2,6-diacetyl-7,9-dihydroxy-8,9b-dimethyl-1,3(2 H,9b H)-二苯并呋喃二酮)。结果表明,通过引入侧链部分可以提高松萝酸的抗病毒活性。用查耳酮修饰似乎是最有效的。我们的研究表明,(-)-松香酸比其(+)-对映体具有更高的抗病毒活性,但在对映体衍生物对(例如烯胺,吡唑和查耳酮)中,(+)-对映体是更有效的病毒抑制剂。对于其他类型的化合物,对映体的抑制活性是可比的。因此,结构的进一步优化可能导致开发出具有替代靶标和病毒抑制作用机理的新型抗流感化合物。
