ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2019; 178:113-122. [PMID: 30999179 DOI: 10.1016/j.ecoenv.2019.04.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Revised: 03/19/2019] [Accepted: 04/03/2019] [Indexed: 06/09/2023]
Abstract
The rational of the current study was to assess whether Tribulus terrestris extract (TTE) could alleviate long-term copper (Cu) overload-induced testicular dysfunction compared to enalapril and losartan. Rats were administered either vehicle (control group, n = 10) or copper sulfate pentahydrate (CuSO4·5H2O, 200 mg/kg, p.o) for 90 days (n = 40). Cu-treated rats were randomized into four equal groups. One group was left untreated (Cu group) while the remaining three groups were daily co-treated with one of the following treatments along with CuSO4: TTE (10 mg/kg, p.o); enalapril (30 mg/kg, p.o); losartan (10 mg/kg, p.o). Excess Cu intake resulted in Cu overload coupled with a significant elevation in systolic blood pressure and serum angiotensin II levels along with a reduction in serum nitric oxide level. All concomitant treatments led to an alleviation of such deleterious effects. However, only losartan failed to ameliorate angiotensin II elevation. Additionally, all treatments protected the testes against Cu-overload-elicited zinc depletion and oxidative stress. Regarding reproductive function, the relative weights of testes, serum levels of testosterone and luteinizing hormone; the expression of steroidogenic genes; the protein levels of angiotensin II type 1 receptor and angiotensin converting enzyme 1, in addition to its activity, they were significantly reduced. Amongst all treatments, only TTE and E were able to revert these reproductive changes. In conclusion TTE and E were able to protect against Cu overload-induced impairment of testicular steroidogenesis. Thus, they might be considered as prophylactic drugs of choice against hypertension and testicular dysfunction to ameliorate Cu overload risk.

Abstract
In the present work, hydrophobic nanoprecipitates (HNPs) of inclusion complexes formed between β-cyclodextrin (βCD) and the avermectins (AVMs) named eprinomectin (EPRI) and ivermectin (IVER) were synthesized and characterized, and their larvicidal activity against Aedes aegypti and human safety against fibroblasts were evaluated. Initially, thermogravimetric analysis/differential thermal analysis data revealed that inclusion increased the thermal stability of AVMs in the presence of βCD. Nuclear magnetic resonance experiments and density functional theory calculations pointed out the inclusion of the benzofuran ring of the two AVMs in the βCD cavity. Isothermal titration calorimetry experiments allowed identification of different binding constants for EPRI/βCD ( Kb = 1060) and βCD/IVER ( Kb = 1700) systems, despite the structural similarity. Dynamic light scattering titrations of AVMs' dimethyl sulfoxide solution in βCD aqueous solution demonstrated that the formed HNPs have lower sizes in the presence of βCD. Finally, the inclusion of EPRI in βCD increased its larval toxicity and reduced its human cytotoxicity, while for IVER/βCD no beneficial effect was observed upon inclusion. These results were rationalized in terms of structural differences between the two molecules. Finally, the EPRI/βCD complex has great potential as an insecticide against A. aegypti larvae with high human safety.

Abstract
The human pathology Wilson disease (WD) is characterized by toxic copper (Cu)
accumulation in brain and liver, resulting in, among other indications,
mitochondrial dysfunction and apoptosis of hepatocytes. In an effort to identify
novel compounds that can alleviate Cu-induced toxicity, we screened the
Pharmakon 1600 repositioning library using a Cu-toxicity yeast screen. We
identified 2 members of the drug class of Angiotensin II Type 1 receptor
blockers (ARBs) that could increase yeast tolerance to Cu, namely Candesartan
and Losartan. Subsequently, we show that specific ARBs can increase yeast
tolerance to Cu and/or the chemotherapeutic agent cisplatin (Cp). The latter
also induces mitochondrial dysfunction and apoptosis in mammalian cells. We
further demonstrate that specific ARBs can prevent the prevalence of Cu-induced
apoptotic markers in yeast, with Candesartan Cilexetil being the ARB which
demonstrated most pronounced reduction of apoptosis-related markers. Next, we
tested the sensitivity of a selection of yeast knockout mutants affected in
detoxification of reactive oxygen species (ROS) and Cu for Candesartan Cilexetil
rescue in presence of Cu. These data indicate that Candesartan Cilexetil
increases yeast tolerance to Cu irrespectively of major ROS-detoxifying
proteins. Finally, we show that specific ARBs can increase mammalian cell
tolerance to Cu, as well as decrease the prevalence of Cu-induced apoptotic
markers. All the above point to the potential of ARBs in preventing Cu-induced
toxicity in yeast and mammalian cells.
