structures have been characterized by IR, 1H NMR, 13C NMR, mass spectral and elemental analysis. The novel compounds were designed as Mycobacterium tuberculosis shikimate kinase (MtSK) inhibitors based on docking studies using Sybyl-X 2.0 software. In silico ADMET predictions revealed that all compounds had minimal toxic effects and had good absorption as well as solubility characteristics. Thus these
合成了一系列吡唑啉衍生物,并通过IR,1 H NMR,13 C NMR,质谱和元素分析对它们的结构进行了表征。该新化合物被设计为结核分枝杆菌iki酸酯激酶(MtSK)抑制剂基于使用Sybyl-X 2.0软件的对接研究。在计算机模拟中ADMET的预测表明,所有化合物均具有最小的毒性作用,并具有良好的吸收性和溶解性。因此,这些化合物可作为开发新的抗结核药物的潜在先导化合物。在测试的化合物4c,5b和6a中,它们显示出有希望的抗结核活性。另外,还使用色氨酸蓝排除法评估了某些化合物对EAC细胞系的细胞毒活性。

A series of Nazarovcyclizations has been studied involving N-heterocyclic-substituted 1-arylprop-2-en-1-one derivatives (aza-chalcones). Superacid catalyzed reactions of these derivatives provide good yields of heterocyclic-substituted 1-indanones. A mechanism is proposed involving diprotonated, superelectrophilic intermediates.

The invention features substituted fused bicyclic compounds, pharmaceutical compositions containing them, and methods of using them to treat or prevent histamine-mediated diseases and conditions.
The rapid synthesis of novel dicyclic spiropyrrolidine was reported, using [3+2]-cycloaddition of isatin N,N′-cyclic azomethine imine 1,3-dipoles, generated from the condensation of substituted isatins and pyrazolidones, with chalcones in 2–5 min. The dicyclic spiropyrrolidine oxoindole was smoothly acquired in moderate to excellent yields (35–95%) with high diastereoselectivities (>20 : 1 dr).
