  • Photochemical rearrangements of highly functionalized longipinene derivatives
    作者:Pedro Joseph-Nathan、Myriam Meléndez-Rodríguez、Carlos M. Cerda-García-Rojas、César A.N. Catalan

    Ultraviolet irradiation of 7β,9α-diacetyloxylongipin-2-en-1-one (3) affords the vulgarone A derivative 5 and compound 7 which possesses a novel tricyclic sesquiterpene skeleton named pingilonane. The photorearrangements of 3 occur via [1,3] sigmatropic shifts of the C4C10 or of the C4C5 bond, respectively. Similarly, irradiation of 7β,8α,9α-triacetyloxylongipin-2-en-1-one (4) affords 6 and 8. Some

  • Antifeedant and Cytotoxic Activity of Longipinane Derivatives
    作者:Carlos Cerda-García-Rojas、Eleuterio Burgueño-Tapia、Luisa Román-Marín、Juan Hernández-Hernández、Teresa Agulló-Ortuño、Azucena González-Coloma、Pedro Joseph-Nathan

    The polyoxygenated longipinane derivatives 1–8 were tested as antifeedant compounds against the herbivorous insects Spodoptera littoralis, Rhopalosiphum padi, and Myzus persicae. Compounds 1–3 and 8 exhibited significant antifeedant activity against S. littoralis and M. persicae. The antifeedant activity against S. littoralis increased moderately after the C-8 hydroxy group in 3 was removed to afford 1 and increased strongly after the remaining two hydroxy groups were acetylated to afford 2. Compound 1 was active on M. persicae. Compounds 1, 3, and 4, with an unsaturated six-membered ring, exhibited an increase in post-ingestive effects on S. littoralis ranging from antifeedant in the case of 1 to toxic for compounds 3 and 4. These compounds did not have any phytotoxic effect on Lactuca sativa. When tested on a panel of tumoral cells, compounds 2 and 6 exhibited moderate selective cytotoxic effects on the p53 null lung carcinoma cells H1299, which were not affected by the drug paclitaxel. In addition, vibrational circular dichroism (VCD) was applied to the representative longipinene derivative 2 to verify its absolute configuration, and the sensitivity of the VCD methodology was evaluated by comparing spectra of the three diastereoisomers (4R,5S,7R,9R,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one (2), (4R,5S,7S,9R,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one, and (4R,5S,7R,9S,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one.
    将多氧长桧烷衍生物 1-8 作为抗草食性昆虫滨海鞘翅目(Spodoptera littoralis)、蚜蝇(Rhopalosiphum padi)和棉铃虫(Myzus persicae)的反食性化合物进行了测试。化合物 1-3 和 8 对滨海鞘翅目昆虫和柿螨具有显著的抗飞虫活性。在去除 3 中的 C-8 羟基生成 1 后,对 S. littoralis 的抗飞虫活性略有增加,而在将剩余的两个羟基乙酰化生成 2 后,抗飞虫活性则有了大幅增加。化合物 1 对 M. persicae 具有活性。化合物 1、3 和 4 具有一个不饱和的六元环,对 S. littoralis 的后消食作用有所增加,从化合物 1 的反消食作用到化合物 3 和 4 的毒性作用不等。这些化合物对仙人掌没有任何植物毒性作用。在对一组肿瘤细胞进行测试时,化合物 2 和 6 对 p53 缺失的肺癌细胞 H1299 显示出中等程度的选择性细胞毒性作用,而紫杉醇对这些细胞没有影响。此外,还对具有代表性的长皮烯衍生物 2 进行了振动圆二色性分析(VCD),以验证其绝对构型,并通过比较三种非对映异构体(4R、5S,7R,9R,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one (2), (4R,5S,7S,9R,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one, and (4R,5S,7R,9S,10R,11R)-7,9-diacetyloxylongipin-2-en-1-one.
