objective: the purpose of this study was to observe the effects of methoxyamine (mx) on the cytotoxic effects and dna damage caused by 5-fluorouoracil (5-fu), in combination with gamma-rays in human colon cancer cell line. materials and methods: in this experimental study, ht29 cells were cultured as a monolayer and treated with different concentrations of 5-fu along with 1 mm mx for 24 h. afte...

Background: Mammalian cell division is regulated by a complex includes cyclin-dependent kinases (Cdks) and cyclins, Cdk/cyclin complex. The activity of the complex is regulated by Cdk inhibitors (CKIs) compressing CDK4 (INK4) and CDK-interacting protein/kinase inhibitory protein (CIP/KIP) family. Hypermethylation of CKIs has been reported in various cancers. DNA methyltransferase inhibitors (DN...

In current research, nine basic esters of para-alkoxyphenylcarbamic acid with incorporated 4-(4-fluoro-/3-trifluoromethylphenyl)piperazin-1-yl fragment, 6i-6m and 8f-8i, were screened for their in vitro antimicrobial activity against Candida albicans, Staphylococcus aureus and Escherichia coli, respectively. Taking into account the minimum inhibitory concentration assay (MIC), as the most activ...

The structure activity relationships of 1H-benzimidazole-8-carboxylic acids (9a-9f), 1H-benzimidazole-8carboxylates (8a-8f) are described. Characteristic compounds showed improved demanding activity over a previously recognized 2-aminobenzimidazole series. In the lead optimization process and structure–activity relationship (SAR) of separate inhibitors based on modification of the lead molecule...
