napththalen-1-yl)ureas, and 1b, a class of indole-pyrimidinyl compounds which were patented respectively, we designed, de novo synthesized, and evaluated two kinds of novel series of lactone benzoylhydrazine derivatives and 2-nitro-1-phenyl-1H-indole derivatives in an effort to develop pharmacologically tractable agents to alleviate the progression of AD. Fourteen of the seventeen synthesized compounds

synthetic route toward newcopper(II) chlorate complexes with potential use in modern advanced ignition or initiation systems is described. Obtained compounds were not only accurately characterized (XRD, IR, UV/Vis EA and DTA) but also investigated for their energetic character (sensitivities, initiation capability and laser ignition). The copper 4-aminotriazolyl chlorate complex showed excellent initiation
描述了一种在现代先进点火或引发系统中具有潜在用途的新型氯酸铜 (II) 复合物的便捷合成路线。获得的化合物不仅被准确表征(XRD、IR、UV/Vis EA 和 DTA),而且还研究了它们的能量特性(灵敏度、引发能力和激光点火)。4-氨基三唑基氯酸铜配合物显示出优异的PETN引发,同时还具有热稳定性和安全性。进行了固态 UV-Vis 测量,以获得对激光引发机制的可能见解。In contrast to expectations, the presented copper(II) chlorate energetic coordination compounds show manageable sensitivities that can be tamed or boosted by the appropriate choice of nitrogen-rich ligands.

the substitution groups of C3 and C4 of coumarin should be relatively large hydrophobic groups and 3) the linker part should be least substituted. Based on the SAR analysis, we synthesized compound 32 as a potent entry inhibitor of EBOV and MARV (IC50 = 0.5 μM for EBOV and 1.5 μM for MARV). The mutation studies of Ebola glycoprotein and molecular docking studies showed that the coumarin and its substituted
3,4‐Bis(1H‐5‐tetrazolyl)furoxan (H2BTF, 2) and its monoanionic salts that contain nitrogen‐rich cations were readily synthesized and fully characterized by multinuclear NMR (1H, 13C) and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses.
