Small molecule compounds and compositions containing said compounds useful for inhibiting signaling by certain Toll-like receptors (TLRs), particularly TLR9, are provided. The compounds and compositions can be used to inhibit immune responses, including unwanted immune responses in particular. Compounds, compositions, and methods are provided to treat a variety of conditions involving unwanted immune responses, including for example autoimmune disease, inflammation, transplant rejection, and sepsis.
A series of novel 1,2,3-benzotriazin-4-one derivatives were synthesized by the reaction of 3-bromoalkyl-1,2,3-benzotriazin-4-ones with potassium salt of 2-cyanoimino-4-oxothiazolidine in the presence of potassiumiodide. Nematicidal assays in vivo showed that some of them exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita, up to 100% at the
通过3-溴烷基-1,2,3-苯并三嗪-4-酮与2-氰基氨基-4-氧噻唑烷的钾盐反应,合成了一系列新的1,2,3-苯并三嗪-4-酮衍生物。碘化钾的存在。杀线虫试验在体内表明,它们中的一些表现出对所造成的黄瓜根结线虫病良好的防治效果南方根结线虫以10.0毫克的L的浓度,最高可达100%-1,表明1,2,3-苯并三-4-one衍生物可能是新型杀线虫剂的潜力。杀线虫活性受分子中取代基类型,取代位置和接头长度的组合影响。浓度为5.0和1.0 mg L –1时的抑制率数据还提供了具有高抑制活性的化合物。当在体外测试时,没有一个对隐孢霉菌有直接抑制作用。体内和体外数据之间显着差异的研究正在进行中。

search for novel more effective insecticides, natural products could be used as ideal template compounds due to their good environmental compatibility, various bioactivities, unique scaffolds and mode of action. We have found that natural product evodiamine, the main active component from the fruits of Evodia rutaecarpa (Juss.) Benth, displayed obvious insecticidal activities against lepidoptera pests
Recyclable (PhSe)<sub>2</sub>-catalyzed selective oxidation of isatin by H<sub>2</sub>O<sub>2</sub>: a practical and waste-free access to isatoic anhydride under mild and neutral conditions
A practical and waste-free synthesis of isatoic anhydride was reported. The feature of this methodology is the simple isolation procedure by filtration, which facilitates the direct recovery and reuse of both organoselenium catalysts and solvents.
