A series of some new tetrahydroindolocarbazole derivatives has been synthesized. The structure of the synthesized compounds has been confirmed by different spectroscopic techniques such as IR, NMR, elemental analysis and massspectrometry. The target compounds were evaluated for their antitumor activity against breast cancer cell line MCF-7, their GI% and their LC50 have been determined. Six of the
已经合成了一系列新的四氢吲哚并咔唑衍生物。合成的化合物的结构已通过不同的光谱技术(例如IR,NMR,元素分析和质谱法)确认。评估了目标化合物对乳腺癌细胞系MCF-7的抗肿瘤活性,确定了其GI%和LC 50。六个合成的化合物对MCF-7细胞系的GI%值超过70%,在71.9%至85.0%之间,此外化合物11的GI%值为99.9%,被认为是合成衍生物中活性最高的衍生物。化合物11 与DOX相比,u PA水平显着降低至3.5 ng / ml。化合物5,11和15显示出在MTAP和CDKN2A的表达显著减少,除了在DNA损伤彗星试验方法的显着降低。进行了分子建模研究,以解释活性配体作为uPA抑制剂的行为。

BIMs (bis-indolylmethanes) (1(a-n)) were synthesized using glacial acetic acid as a protic acid for promotion of the condensation reaction of indoles with aldehydes in high yields (86-98 %). Corresponding tetrahydroindolo[2,3-b]carbazoles (2(a-m)) were synthesized via condensation of BIMs with aldehydes. Ten synthesized compounds have been submitted to the national cancer institute in the USA where all the submitted samples have been selected for one dose screening. As a result of the one dose screening of BIMs (1(e,f,h,i,n)) and of the indolocarbazoles (2(e,f,h,i,j)) the average highest cytostatic effects was recorded here for the BIM 1(h) and the indolocarbazole (2e) that showed the lowest mean values of "47.39%" and of "21.63%" respectively. Both compounds (1(h) and 2(e)) were further tested in five dose screening with the tested substance (1(h)) being significantly more sensitive for several cancers cell line as corresponding to their GI(50) values. Furthermore, the basically substituted derivative 2(e) showed the highest antipoliferative activity in a nanomolar scale towards the three selected cancers cell lines Non small lung cell NCI-H460 with GI(50) "616 nM", Ovarian Cancer cell line OVCAR-4 with GI(50) "562 nM" and Breast Cancer cell line MCF7 with GI(50) "930 nM".

posed by MRSA. In this work, about 60 compounds of bis-indoles (diindolylmethanes and diindolylmethenes) were synthesized and screened as antibacterialagents against S. aureus and methicillin-resistant S. aureus (MRSA). The quantitative structure-activityrelationships (QSAR) of the compounds were also carried out in this work. Results: Good numbers of the compounds appear to be good antibiotic candidates
