  Synthesis and Biological Screening of 2-Substituted 5,6-Dihydro-5-oxo- 4H-1,3,4-oxadiazine-4-propanenitriles and of Their Intermediates

  摘要：

  To evaluate the effect of substituents on biological activities of electron-rich N-containing heterocycles, the variably 2-substituted 5,6-dihydro-5-oxo-4H-1,3,4-oxadiazine-4-propanenitriles 26-33 were synthesized and evaluated for antibacterial, antifungal, and enzyme-inhibition activities. The target compounds were obtained from alkyl 4- or 3-hydroxy benzoates 1 and 2, respectively, and from methyl indoleacetate 3. The phenolic OH group of benzoates I and 2 were substituted with p-toluenesulfonyl ( --> 4 and 5), benzoyl ( 6 and 7), and benzyl groups ( 8 and 9) and then converted to 5,6-dihydro-5-oxo-4H-1,3,4-oxadiazine-4-propanenitriles. To establish structure-activity relationships (SAR), a pharmacological screening of the intervening intermediates was also conducted, which revealed that the intermediate hydrazide 11 possesses significant antimicrobial and MAO-A inhibiting properties and intermediates 12,24,28, and 29 appreciable antifungal activities. Compound 7 inhibits a-chymotrypsin.

  was designed and synthesized, and the target compounds were evaluated for their insecticidal activity against five aphid species. Most of the tested compounds exhibited potent insecticidal activity against Eriosoma lanigerum (Hausmann), Myzus persicae, and Aphis citricola. Compounds 20g and 24g displayed the highest activity against E. lanigerum, showing LC50 values of 27.6 and 30.4 μg/mL, respectively

  设计并合成了一系列具有取代的1,3,4-恶二唑结构的新型甾体衍生物，并评估了目标化合物对五种蚜虫的杀虫活性。大多数测试的化合物表现出对鼠尾草（Hausmann）、桃蚜和柑橘蚜的有效杀虫活性。化合物20g和24g对E. lanigerum 的活性最高，LC 50值分别为 27.6 和 30.4 μg/mL。E. lanigerum中肠细胞的超微结构变化通过透射电子显微镜检测，表明这些甾体恶唑衍生物可能通过破坏昆虫中肠细胞的线粒体和核膜来发挥其杀虫活性。此外，田间试验表明，化合物20g表现出与阳性对照毒死蜱和噻虫嗪对E. lanigerum的效果相似，在200 μg/mL剂量下21天后达到89.5%的控制率。我们还通过测定三种杀虫剂解毒酶的活性研究了E. lanigerum 中目标化合物的水解和代谢。复合物20g50 μg/mL 对羧酸酯酶的抑制作用类似于已知的抑制剂磷酸三苯酯。上述结果证明了

  Eight new β-N-substituted acyl hydrazides along with their corresponding acyl derivatives were synthesized and screened for in vitro β-glucuronidase inhibition and found to be active against the enzyme. All of these compounds were found to be noncompetitive inhibitors except for N′-(2-cyanoethyl)-4-hydroxy benzohydrazide (10), which was found to be an uncompetitive inhibitor. Structure–activity relationship studies indicated that the benzyloxy group present in compounds 12 and 13 is responsible for the β-glucuronidase inhibition activity.
