evaluation of the selective cytotoxicity and genotoxicity of three synthetic -nitrobenzyl derivatives in human cancer cell lines, with and without metabolic activation.

Although the presence of nitro groups in chemicals can be recognized as structural alerts for mutagenicity and carcinogenicity, nitroaromatic compounds have attracted considerable interest as a class of agents that can serve as source of potential new anticancer agents. In the present study, the cytotoxicity, genotoxicity, and mutagenicity of three synthetic -nitrobenzyl derivatives (named , and ) were evaluated by employing human breast and ovarian cancer cell lines. A series of biological assays was carried out with and without metabolic activation.

Genotoxicity and Anticancer Effects of the Aminothiophene Derivatives SB-44, SB- 83, and SB-200 in Cancer Cells.

Introduction: Thiophene derivatives have been widely studied as promising options for the treatment of solid tumors. Previous studies have shown that thiophene derivatives have antileishmanial activity and cytotoxic activity against breast, colon, and ovarian cancer cells.

Methods: In our study, we evaluated the anticancer activities of three aminothiophene derivatives: SB-44, SB-83, and SB-200, in prostate and cervical adenocarcinoma cells.

Metabolic activation enhances the cytotoxicity, genotoxicity and mutagenicity of two synthetic alkaloids with selective effects against human tumour cell lines.

The pharmacological potential of drugs must be evaluated to establish their potential therapeutic benefits and side effects. This evaluation includes assessment of the effects of hepatic enzymes that catalyse their metabolic activation. Previously, our research group synthesized and characterized a set of synthetic 3-alkyl pyridine alkaloid (3-APA) analogues that cause in vitro cytotoxic, genotoxic, and mutagenic effects in various human cancer cell lines.

Ultrasound elastography in patients with fatty liver disease.

Hepatic steatosis, or fatty liver disease, occurs due to the accumulation of lipids in hepatocytes. When it becomes chronic, lobular inflammation develops and the disease can evolve to hepatic fibrosis, liver cirrhosis, or hepatocellular carcinoma. Early diagnosis is desirable because patients diagnosed in the early stage of the disease respond better to treatment.

Digoxin reduces the mutagenic effects of Mitomycin C in human and rodent cell lines.

Digoxin is a drug widely used to treat heart failure and studies have demonstrated its potential as anticancer agent. In addition, digoxin presents the potential to interact with a series of other compounds used in medicine. The aim of the present study was to evaluate in vitro the cytotoxicity, genotoxicity and mutagenicity of digoxin and its potential to interact with the mutagen Mitomycin C (MMC).

Synthesis and biological evaluation of novel 3-alkylpyridine marine alkaloid analogs with promising anticancer activity.

Cancer continues to be one of the most important health problems worldwide, and the identification of novel drugs and treatments to address this disease is urgent. During recent years, marine organisms have proven to be a promising source of new compounds with action against tumoral cell lines. Here, we describe the synthesis and anticancer activity of eight new 3-alkylpyridine alkaloid (3-APA) analogs in four steps and with good yields.
