  product geodin (1), isolated from the marine-derived fungus Aspergillus sp., a series of new ether derivatives (2–37) was designed and semisynthesized using a high-yielding one-step reaction. In addition, the insecticidal and antibacterial activities of all geodin congeners were evaluated systematically. Most of these derivatives showed better insecticidal activities against Helicoverpa armigera Hübner

  为了增强从海洋来源的真菌曲霉菌中分离出来的天然产物大地素 (1) 的生物活性，我们设计了一系列新的醚衍生物 (2-37)，并使用高产一步反应进行半合成。此外，还系统评价了所有geodin同系物的杀虫和抗菌活性。这些衍生物中的大多数对棉铃虫表现出比 1 更好的杀虫活性。特别是，15 表现出有效的杀虫活性，IC50 值为 89 μM，与阳性对照印楝素 (IC50 = 70 μM) 相当。此外，5、12、13、16、30和33对金黄色葡萄球菌和杀鲑气单胞菌具有很强的抗菌活性，MIC值在1.15-4.93 μM范围内。初步构效关系表明，在1中引入卤代苄基尤其是氟苄基并取代4-OH可能是提高geodin杀虫和抗菌活性的关键因素。

• Inner core’s seismic anisotropy is related to its rotation

  The inner core has a differential rotation relative to the crust and mantle, the relative linear velocity between the solid inner core and the molten outer core is the biggest at the equator and zero at pole area, As a result, the inner core grows faster at the equator than at the pole area. The gravitational force drives the material flow from the equator to the pole area and makes the inner core remain quasi-orbicular. The corresponding axial symmetric stress field makes c-axes of hexagonal close packed (hcp) iron align with inner core's rotation axis, resulting in observed seismic anisotropy.
