In addition to intentional doping, inadvertent exposure through contaminated dietary supplements has emerged as a significant concern, purportedly as well as evidently contributing to AAFs involving SARMs. Thus, the differentiation of inadvertent intake and intentional abuse of S-23 is of growing relevance. This study aimed at investigating the urinary concentration profile of microdosed S-23 and to characterize the elimination pattern. Single and multidose administration studies with 1, 10, and 50 μg of S-23 were conducted, and collected urine samples were analyzed by LC–MS/MS following enzymatic hydrolysis and solid-phase extraction. The analytical method was validated for a semiquantitative detection of S-23 and characterized by a limit of detection of 1 pg/mL. A total of 18 metabolites was detected in human in vivo samples following oral administration of microdosed S-23.

In the present study, we demonstrated that YHS could induce idiosyncratic drug-induced liver injury (IDILI) in the inflammatory activation models.

In addition, YHS significantly increased the levels of TNF-α, IL-1β, and IL-6. Therefore, we believe that the mechanism of toxicity may be related to the TNF and NF-κB signaling pathways, with glycerophospholipid metabolism, sphingolipid metabolism, and arachidonic acid metabolism also playing important roles.

Initially, the chemical constituents of PO were identified using UHPLC–Q-Exactive Orbitrap HRMS. Subsequently, network pharmacology, molecular docking, and RNA-seq were employed to screen potential active components of PO targeting MI and predict their molecular mechanisms. Then, the molecular mechanisms were verified using western blotting and ELISA in MI mice. A total of 45 components were identified from PO, with 14 potential active compounds interacting with 204 MI-related genes. The findings suggest that PO could alleviate heart damage. The RNA-seq results indicated 244 potential targets regulated by PO. Integrating RNA-seq and network pharmacology analyses revealed that the toll-like receptor signaling pathway plays an important role, alongside the PI3K-Akt. Notably, PO reduced the expression of TLR4 and TLR2 while increasing p-Akt and p-PI3K levels in MI mice, leading to decreased inflammatory cytokines and apoptosis-related proteins.
