elemental analysis in certain cases. Antitumor activities as a trial to obtain more effective and less toxic agents were evaluated. The antitumor activity results indicated that the selected tetrahydroacridinederivatives showed antitumor activity against the liver cancer (HEPG2) tumor cell line tested, but with varying intensities in comparison to the known anticancer drugs, 5-fluorouracil and doxorubicin
这项研究旨在合成和评估许多9-取代的四氢ac啶衍生物的化学治疗活性。起始原料a啶酰肼可通过环己酮和邻氨基苯甲酸之间的相互作用,然后将产物氯化,然后将最后一种化合物与水合肼缩合来制备。新化合物的结构由IR建立,1在某些情况下,还需要1 H NMR,MS光谱和元素分析。评价了抗肿瘤活性,以期获得更有效和毒性更低的药物。抗肿瘤活性结果表明,所选的四氢ac啶衍生物对测试的肝癌(HEPG2)肿瘤细胞系具有抗肿瘤活性,但与已知的抗癌药物5-氟尿嘧啶和阿霉素相比强度不同。已发现化合物VIb对肝癌(HEPG2)呈剂量依赖性,活性最高,并具有明显的生长抑制作用(浓度为0.694μg/ ml),而化合物XVIIIa在生长抑制活性方面排名第二(2.97) μg/ ml浓度)。
Facile Synthesis, Antioxidant and Antimicrobial Activity of Amino Methylene Bisphosphonates
A green and efficient preparation method for the amino bisphosphonates is accomplished by simple mixing and stirring of diethylphosphite, triethylorthoformate and various amines in the presence of amberlyst-15 as catalyst at room temperature under solvent free conditions. The title compounds are characterized by IR, 1H-, 13C-, 31P-NMR and mass spectra, also studied their antimicrobial and antioxidant activity.

analyses. Some of the new synthesized compounds were assayed for their in vitro antibacterialactivity against Gram-positive bacteria, Staphylococcus aureus and Staphylococcus epidermidis, Gram-negative bacteria, Escherichia coli and Klebsiella pneumonia and antifungal activity against Aspergillus fumigatus and Candida albicans. Most of the new compounds showed significant antibacterial and antifungal

crystallography studies. Three of its Ru(III) complexes were synthesized and characterized by analytical and spectroscopic studies. The DNA binding properties of HL and its Ru(III) complexes have been investigated by electronic absorption spectroscopy. Also, HL and its Ru(III) complex [RuCl2(AsPh3)L] were tested for DNA cleavage properties. The results showed that the complex cleaves DNA more rapidly than the
席夫碱 (HL) 已被合成并通过物理化学、光谱和 X 射线晶体学研究表征。其三种 Ru(III) 配合物被合成并通过分析和光谱研究表征。已通过电子吸收光谱研究了 HL 及其 Ru(III) 配合物的 DNA 结合特性。此外,还测试了 HL 及其 Ru(III) 复合物 [RuCl2(AsPh3)L] 的 DNA 切割特性。结果表明,复合物比游离配体更快地切割 DNA。此外,还进行了 HL 和复合物 [RuCl2(AsPh3)L] 的细胞毒性的体外研究。
