(4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid is new synthesized substance obtained from cysteine and valine. Thiazolidine derivates have important biological responses so scientists work intensively on these compounds in recent years. It is obvious that thiazolidine contained compounds will be used in future in the pharmaceutical industry to treat important diseases. Median lethal concentrations (LC50) for 48 h and 96 h were found as 1.106±0.052 mM and 0.804mM ± 0.102 respectively. According to LC50, exposure doses were determined as control, 0.4 mM, 0.2 mM and 0.1 mM (4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid. Developmental toxicity and apoptotic features on zebrafish development were evaluated in this study. The results of this study indicate that (4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid exposure cause developmental defects like pericardial edema, bent spine, tail malformation, blood accumulation, yolk sac edema but on the other hand concentration-dependent decrease in apoptotic rate. Likewise, concentration-dependent decrease in hatching and increase in mortality of embryos were also detected.
Tribenuron methyl is a herbicide that is used to control annual and perennial dicots in cereals and fallow land. Pesticides can access aquatic ecosystems via groundwater and affect water quality and aquatic life. Our study evaluated histopathological effects of tribenuron methyl on ovary of the zebrafish Danio rerio (Hamilton, 1822). Ovary of the fishes in control group not exposed to the herbicide showed normal histological architecture. In the fishes exposed to tribenuron methyl, vacuolisation, edema and dysmorphism were recorded. Significant decrease in the number of primary and mature oocytes as well as dose dependent increase in the number of atretic oocytes were recorded in fishes exposed to tribenuron methyl.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
