  • Stereochemistry, lipid length and branching influences Mincle agonist activity of monoacylglycerides

    than trehalose dibehenate (TDB), the prototypical Mincle agonist. Across the compound classes, the activity of the sn-1 substituted isomers was greater than the sn-3 counterparts. None of the representative compounds were cytotoxic, thus mitigating cytotoxicity as a potential mediator of cellular activity. Taken together, 6h (sn-1, iC26+1), 8a (sn-1, C32) and 8b (sn-3, C32) exhibited the best immunostimulatory
    在这里,我们报道了一系列对映体纯的线性,异支化和α支化单酰基甘油酯(MAGs)的合成,总收率为63-72%。探索了使用NFAT-GFP报告基因细胞通过人巨噬细胞诱导型C型凝集素(hMincle)发出信号的能力,以及化合物激活人单核细胞的能力。从这些研究中,人单核细胞的Mincle激活和白介素8(IL-8)的产生需要酰基链长度≥C22的MAG。此外,与线性MAG相比,异支MAG导致更明显的免疫反应,而含有C-32酰基链的α支MAG则比典型的Mincle激动剂海藻糖二山hen酸酯(TDB)活化细胞的程度更高。在整个复合类别中,sn的活动-1个取代的异构体大于sn -3对应的异构体。代表性化合物均无细胞毒性,因此可减轻细胞毒性,将其作为细胞活性的潜在介质。两者合计,6h(sn -1,iC26 + 1),8a(sn -1,C32)和8b(sn -3,C32)表现出最佳的免疫刺激特性,因此具有作为疫苗佐剂的潜力。
  • Insecticidal Activity of Extracts, Fractions, and Pure Molecules of Cissampelos pareira Linnaeus against Aphid, Aphis craccivora Koch

    Aphis craccivora Koch is a polyphagous and major pest of leguminous crops causing significant damage by reducing the yield. Repeated application of synthetic insecticides for the control of aphids has led to development of resistance. Therefore, the present study aimed to screen the insecticidal activity of root/stem extracts/fractions, and pure molecules from Cissampelos pareira Linnaeus against A. craccivora for identification of lead(s). Among root extract/fractions, the n-hexane fraction was found most effective (LC50 = 1828.19 mg/L) against A. craccivora, followed by parent extract (LC50 = 2211.54 mg/L). Among stem extract/fractions, the n-hexane fraction (LC50 = 1246.92 mg/L) was more effective than the water and n-butanol fractions. Based on GC and GC-MS analysis, among different compounds identified in the n-hexane fraction of root and stem, ethyl palmitate (known to possess insecticidal activity) was present in the highest concentration (24.94 to 52.95%) in both the fractions. Among pure molecules, pareirarineformate was found most effective (LC50 = 1491.93 mg/L) against A. craccivora, followed by cissamine (LC50 = 1556.31 mg/L). Parent extract and fractions of C. pareira possess promising activity against aphid. Further, field bio-efficacy studies are necessary to validate the current findings for the development of botanical formulation.

    Aphis craccivora Koch是一种多食性和主要的豆科作物害虫,通过减少产量造成显著损害。反复使用合成杀虫剂来控制蚜虫已经导致了抗药性的产生。因此,本研究旨在筛选来自Cissampelos pareira Linnaeus的根/茎提取物/分馏物和纯分子的杀虫活性,以识别潜在的领先物质。在根提取物/分馏物中,正己烷分馏物对A. craccivora的效果最好(LC50 = 1828.19 mg/L),其次是母体提取物(LC50 = 2211.54 mg/L)。在茎提取物/分馏物中,正己烷分馏物(LC50 = 1246.92 mg/L)比水和正丁醇分馏物更有效。基于GC和GC-MS分析,在根和茎的正己烷分馏物中识别出的不同化合物中,乙酸乙酯(已知具有杀虫活性)在两个分馏物中的浓度最高(24.94至52.95%)。在纯分子中,pareirarineformate对A. craccivora的效果最好(LC50 = 1491.93 mg/L),其次是cissamine(LC50 = 1556.31 mg/L)。C. pareira的母体提取物和分馏物具有很好的杀虫活性。进一步的田间生物效力研究有必要验证当前的发现以开发植物制剂。
