Synthesis and Quantitative Structure–Activity Relationship (QSAR) Study of Novel <i>N</i>-Arylsulfonyl-3-acylindole Arylcarbonyl Hydrazone Derivatives as Nematicidal Agents
natural-product-based pesticidal agents, 54 novel N-arylsulfonyl-3-acylindole arylcarbonyl hydrazonederivatives were prepared, and their structures were well characterized by 1H NMR, 13C NMR, HRMS, ESI-MS, and mp. Their nematicidal activity was evaluated against that of the pine wood nematode, Bursaphelenchus xylophilus in vivo. Among all of the derivatives, especially V-12 and V-39 displayed the best
在我们旨在发现和开发基于天然产物的杀虫剂的程序的继续中,制备了54种新颖的N-芳基磺酰基-3-酰基亚芳基芳基羰基hydr衍生物,并通过1 H NMR,13 C NMR对其结构进行了很好的表征, HRMS,ESI-MS和mp。在体内对它们的杀线虫活性针对松木线虫Bursaphelenchus xylophilus进行了评估。在所有衍生物中,尤其是V-12和V-39表现出最有希望的杀线虫活性,LC 50值分别为1.0969和1.2632 mg / L。这建议引入R 1和R 2为了进一步制备这些作为杀线虫剂的化合物,可以考虑将R 3作为吸电子取代基,R 3作为甲基,R 4作为苯基作为具有吸电子取代基的化合物。六个选定的描述符是WHIM描述符(E1m),两个GETAWAY描述符(R1m +和R3m +),负担特征值描述符(BEHm8)和两个边缘邻接索引描述符(EEig05x和EEig13d)。定量
Anti HIV-1 agents 5: Synthesis and anti-HIV-1 activity of some N-arylsulfonyl-3-acetylindoles in vitro
In continuation of our program aimed at the discovery and development of compounds with superior anti-human immunodeficiency virus type 1 (HIV-1) activity, 21N-arylsulfonyl-3-acetylindole analogs (2a-u) were synthesized and preliminarily evaluated as HIV-1 inhibitors in vitro. Among of all the analogs, several compounds exhibited significant anti-HIV-1 activity, especially N-phenylsulfonyl-3-acetyl-6-methylindole (2j) and N-(p-ethyl)phenylsulfonyl-3-acetyl-6-methylindole (2n) showed the most potent anti-HIV-1 activity with EC50 values of 0.36 and 0.13 mu g/mL, and TI values of >555.55 and 791.85, respectively. It demonstrated that introduction of the acetyl group at the 3-position of N-arylsulfonyl-6-methylindoles could generally lead to the more potent analogs. (C) 2010 Elsevier Ltd. All rights reserved.
