The present invention relates to novel compounds of Formulae I-XI: wherein each A, A', Q, Q', W, Rw, Y, and Z, and -- are as defined herein, which inhibit NOD-like receptor protein 3 (NLRP3) inflammasome activity. The invention further relates to the processes for their preparation, pharmaceutical compositions and medicaments containing them, and their use in the treatment of diseases and disorders mediated by NLRP3.
theoretical predictions suggest similar detonation velocities and pressures for both compounds, actual detonation performance tests indicate that ECPs-2 has stronger explosive power and initiating capability, with potential for use as a laser initiator (E = 126 mJ). The simple preparation method and inexpensive starting materials enrich the research on primary explosives.
对于含能化合物,其结构决定其性能,即使其结构的微小变化也会对其性能产生重大影响。含能材料的应用场景多种多样,其性能要求也各不相同。为了研究不同取代基位置对起爆药性能的影响,我们制备了两种Ag( I )基配合物,[Ag(2-IZCA)ClO 4 ] n ( ECPs -1 )和[Ag(4-IZCA) ClO 4 ] n ( ECPs-2 ),使用结构异构配体1H-咪唑-2-碳酰肼( 2-IZCA )和1H-咪唑-4-碳酰肼( 4-IZCA )。使用红外、元素分析和单晶X射线衍射证实了结构。实验结果表明两种ECP均表现出良好的热稳定性。然而,与ECPs-1相比,ECPs-2表现出较低的热初始分解温度(T d = 210°C)、较低的机械敏感性(IS = 27 J,FS = 84 N)和更集中的能量输出。尽管理论预测表明两种化合物的爆速和压力相似,但实际爆轰性能测试表明ECPs-2具有更强的爆炸
Pentafluorophenyl ester activation for the preparation of N,N′-diaroylhydrazines

Procedures are reported for the preparation of N,N'-diaroylhydrazines using pentafluorophenyl (Pfp) ester activation of aryl carboxylic acids. Mild conditions which avoid intermediate protection of ring substituents, allows the synthesis of both symmetrical and unsymmetrical diaroylhydrazines in high yields. The recent discovery of potent HIV-1 integrase inhibition by N,N'-bis-salicylhydrazine (1) highlights the potential importance of this class of compounds. The stability of pre-activated Pfp ester intermediates and the facility with which N,N'-diaroylhydrazines can be synthesized using this procedure (stirring at room temperature in DMF) may make the method particularly attractive for synthesis of hydrazide libraries.
