“…Therefore, drugs that induce apoptosis can be used as potential tools in cancer therapy. In this study, our data showed that [C 12 min]Cl induced apoptosis in a concentration‐dependent and time‐dependent manner (Figure ), which is consistent with reports on spinosad‐induced apoptosis in HepG2 cells and HEK293 cells, and deoxynivalenol‐induced apoptosis in DF‐1 cells …”

This study purposes to assess the cytotoxicity of 1-dodecyl-3-methylimidazolium chloride ([C 12 min]Cl) in human hepatocellular carcinoma (HepG2) cells. To this end, HepG2 cells were exposed to a range concentration of [C 12 min]Cl and evaluated cell viability, genotoxicity, oxidative stress, apoptosis, cell cycle, and apoptosis-related gene expression to determine cytotoxicity. The outcomes showed that [C 12 min]Cl curbed HepG2 cell growth and reduced cell viability in a concentration-and time-dependent manner.Moreover, our assay results also revealed that exposure to [C 12 min]Cl prompted DNA damage and apoptosis, reduced SOD and GSH content, enhanced MDA level, and changed the cell cycle of HepG2 cells. In addition, [C 12 min] Cl caused alters in the expression levels of p53, Bax, and Bcl-2, indicating that p53 and Bcl-2 family may be involved in the cytotoxicity and apoptosis of HepG2 cells induced by [C 12 min]C1. In summary, these results indicate that [C 12 min]Cl exerts genotoxicity, physiological toxicity and prompts apoptosis in HepG2 cells, and is not an alleged green solvent.

“…Compounds 1 - 5 were tested for cytotoxic activity against human liver cancer cell line HepG2. This cell line is commonly used in toxicological studies for mycotoxins and pesticides. − Compounds 3 and 4 killed more than 90% of the cells at concentration of 12 and 6 μg/mL, respectively. Compound 5 showed weak toxicity at 12 μg/mL (15% of dead cells comparing to control), while 1 and 2 were nontoxic (Table ).…”

Two new natural 10-membered macrolides (1, 2) and one chromene-4,5-dione derivative (3), named stagonolides J and K and stagochromene A, respectively, were isolated from the phytopathogenic fungus Stagonospora cirsii S-47, together with two known compounds, stagonolide A (4) and herbarumin I (5). Stagonolides J and K and stagochromene A were characterized as (5E,7R*,8S*,9R*)-7,8-dihydroxy-9-propyl-5-nonen-9-olide, (5E,7R,9S)-7-hydroxy-9-propyl-5-nonen-9-olide, and (2R*,3R*)-3-hydroxy-2-propyltetrahydro-2H-chromene-4,5(3H,4aH)-dione, respectively, by spectroscopic (mostly by NMR and ESIMS) data. Compounds 1–5 showed different rates of phytotoxic activity on punctured leaf discs of Sonchus arvensis. The antimicrobial, cytotoxic, and antiprotozoal activity of isolated compounds was also evaluated. Based on our data, stagonolide K and herbarumin I can be proposed as a potential scaffold for the development of a new natural herbicide and estimated as possible selection/quality markers of a bioherbicide based on S. cirsii, while stagonolide A can be considered as a mycotoxin.

“…Growth inhibition and biochemical effects caused by trichlorfon were also observed in embryos of Oreochromis niloticus and D. rerio exposed to trichlorfon . In summary, the pesticide trichlorfon may induce DNA damage and apoptosis in 2 ways: (1) via oxidative stress (for instance, excessive ROS (reactive oxygen species)), which may promote DNA damage and apoptosis; and (2) via the mitochondrial pathway . MN and alterations in erythrocyte nuclear morphology can lead to cell death and thus to metabolic damage, pathology and other pathophysiological conditions .…”

Trichlorfon is an organophosphate insecticide widely used in aquaculture and agriculture. Little is known about the effects of long-term of low doses trichlorfon exposure on amphibians. In this study, we investigated the effects of low doses trichlorfon on Rana chensinensis tadpoles after exposure to 0.01, 0.1, and 1.0 mg/L trichlorfon for 2 and 4 weeks. Survival, growth, development and mortality were monitored regularly over the course of exposure. The results showed that trichlorfon led to a decrease in tadpole survival. Reductions in growth and disruptions to the development of tadpoles were observed in trichlorfon treatments. Morphological abnormalities of affected tadpoles included axial flexures, skeletal malformations and lateral kinks. Trichlorfon increased the frequency of micronucleus (MN) formation in circulating erythrocytes of tadpoles exposed for 2 weeks to 0.1 and 1.0 mg/L trichlorfon. At all concentrations, an enhanced frequency of MN formation was observed in tadpoles exposed for 4 weeks. Exposure to trichlorfon induced other nuclear abnormalities such as lobed and notched nuclei only in tadpoles exposed to 1.0 mg/L trichlorfon for 4 weeks. In addition, exposure to trichlorfon within the 0.01-1.0 mg/L range increased the genetic damage index in hepatic tissues in all treatments. Apoptosis-associated DNA fragmentation in hepatic tissues occurred in a weak ladder-like pattern. This study presents evidence of low doses trichlorfon effects on amphibians, highlighting the properties of this organophosphate insecticide that jeopardize nontarget species exposed to trichlorfon.
