| Abstract The identification of antitumoral substances is the focus of intense biomedical research. Two structural analogues of thalidomide, LNO3 and L3, are two synthetic compounds that might possess such antitumor properties. We evaluated the toxicological effects of these substances, including cytotoxicity, genotoxicity and induction of apoptosis in HTC cells. Additionally, the production of free radicals (nitric oxide and superoxide) was investigated, and the expression of caspases genes 3, 8, and 9 were determined by RT-qPCR. The compounds exhibited cytotoxic effects that resulted in inhibited cell proliferation. LNO3 showed to be more effective and toxic than L3 in all assays. LNO3 stimulated the release of NO and superoxide, which was accompanied by... |

| Abstract Plants are the main sources of natural antioxidants in the form of phenolic compounds, which help human beings to deal with oxidative stress, caused by free radical damage. For this reason, the present study was carried out to evaluate the antiproliferative, antioxidant and inhibition of oxidative DNA damage activities of n-butanol extract obtained from aerial parts of Limonium bonduelli. The antioxidant potential was determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and inhibition of lipid peroxidation assay. Antiproliferative activity was evaluated using xCELLigence RTCA instrument on two tumor cell lines; HT-29 (human colon adenocarcinoma) and HeLa (human cervix carcinoma). DNA damage inhibition was evaluated using... |
