设计并合成了一系列新的脱氢松香酸1,3,4-恶二嗪-5(6H)-one衍生物(6a–n)作为潜在的抗微生物剂和抗肿瘤剂。它们的结构通过IR,1 H NMR,13 C NMR,MS和元素分析进行表征。使用连续稀释法评估所有标题化合物对四种细菌和三种真菌菌株的抗菌活性。其中,化合物6e对枯草芽孢杆菌具有最高的抗菌活性。最低抑菌浓度(MIC)值为1.9μg/ mL。此外,还通过MTT比色法对三种人类癌细胞系(MCF-7,SMMC-7772和HeLa)测定了标题化合物的体外细胞毒性活性。结果,化合物6b,6g,6k和6m表现出对至少一种IC 50值低于10μM的细胞系的显着抑制作用。特别发现化合物6m对MCF-7,SMMC-7721和HeLa细胞的IC 50值分别为2.26±0.23、0.97±0.11和1.89±0.31μM ,是最有效的衍生物,与阳性对照依托泊苷相当。

The present invention relates to new cardiotonic Steroid Compounds of Formula (I) or (II) wherein X1, X2, X3, L, R1, R2, R3, R4, and R5 have the same meaning as that defined in the Claims. The invention also relates to the use of said Compounds as medicaments, in particular in the treatment of Cancer.
available N‐aryl conjugated hydrazones with tert‐butyl iodide has been developed. In this reaction, tert‐butyl iodide is used as anhydrous HI source, and the generated HI acts as a Brønsted acid and a reducing agent. This operationally simple method allows access to various indole derivatives. Furthermore, the procedure can be applied to the synthesis of biologicallyactive compounds.
A method of treating cancer in which a compound that inhibits the expression, production or release of IL-10 by immune cells is combined with a compound that stimulates the production of IL-12 when given in combination with, or in the presence of TNFa. Said method is effective when provided in addition to standard therapies, notably chemotherapy using cytotoxic drugs and other forms of immune therapy including therapeutic vaccines.
