A critical review of the environmental occurrence and potential effects in aquatic vertebrates of the potent androgen receptor agonist 17β‐trenbolone

Environmental Toxicology and Chemistry, Journal Year: 2018, Volume and Issue: 37(8), P. 2064 - 2078

Trenbolone acetate is widely used in some parts of the world for its desirable anabolic effects on livestock. Several metabolites acetate, including 17β-trenbolone, have been detected at low nanograms per liter concentrations surface waters associated with animal feedlots. The 17β-trenbolone isomer can affect androgen receptor signaling pathways various vertebrate species comparatively concentrations/doses. present article provides a comprehensive review and synthesis existing literature concerning exposure to biological an emphasis potential risks aquatic animals.

Exogenous Coreactant-Free Electrocatalytic Reactive Oxygen Species-Driven Dual-Signal Molecularly Imprinted Electrochemiluminescence Sensor for the Detection of Trenbolone

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 30, 2025

Conventional dual-signal electrochemiluminescence (ECL) sensors feature high sensitivity and reliability, but the involvement of coreactants inevitably results in a complex configuration shows reproducibility risk. Here, we propose an exogenous coreactant-free platform, comprising luminol (anodic luminophore), CdSe quantum dots (cathodic Co3O4/Ti3C2 electrocatalyst (coreaction promoter). At different redox potentials, induces water oxidation oxygen reduction to produce •OH O2•- radicals, which subsequently drive cathodic anodic ECL emission, respectively. The pathways are confirmed by reactive species (ROS) scavenging, effect dissolved is excluded. By integrating with molecular imprinting technology, this sensor employed for quantitative detection trenbolone. It exhibits sensitivity, broad linear range (1.0 × 101 1.0 108 fg mL-1), low limit, capability real samples. This work presents new endogenous ROS-driven that excludes use offers insights into ROS generation design.

Electrochemiluminescence Sensor with Controlled-Release Triggering Electrostatic Attraction Elimination Mechanism for Trenbolone Trace Detection

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(36), P. 13463 - 13469

Published: Aug. 30, 2023

A controlled-release strategy can meet the needs of sensitive environmental monitoring for pollutants through a self-on/off mode. In this work, an electrochemiluminescence (ECL) biosensor with triggering electrostatic attraction elimination and biomolecular stimulated response strategies was constructed to detect steroid hormones sensitively. The blocked pores on aminated mesoporous silica nanocontainers were opened by specific binding between trenbolone (TB) antigen antibody. released l-cysteine counteracted negative charge MnO2 NF surface redox reaction –SH MnO2, making interaction NFs Ru(dcbpy)32+ disappear. ECL signal electrode, thus completing strategy. addition, TB antibody as target competition standard substance, used substance. Moreover, substrate increased active area effectively catalyzing production OH• O2•–, endowing coreactant-catalytic enhancement characteristic further improving its performance. This brought about low limit detection 2.53 fg/mL biosensor, which contributed feasible idea efficient trace analysis in environment.
