A potential link has been reported between skin exposure to aromatic amines, such as ortho-toluidine (OT) and 3,3'-dichloro-4,4'-diaminodiphenylmethane (MOCA), and bladder cancer cases observed in Japanese chemical factories. To evaluate this association, we explored the permeability of OT and MOCA through pig skin and investigated the subsequent changes in plasma and urine concentrations in rats following percutaneous exposure. Employing Yucatan micropig skin, we first executed a permeability test by affixing the skin to a diffusion cell and applying 14C-labeled OT or MOCA.

Background: Elinzanetant is a dual neurokinin-1,3 receptor antagonist in development for the treatment of menopausal vasomotor symptoms. The objectives of these studies were to characterize the mass balance and biotransformation of elinzanetant.
Methods: In the clinical evaluation, whole blood, plasma, urine, and feces were collected from healthy fasted male volunteers (n = 6) following a single dose of 120 mg [C]-elinzanetant oral suspension for analysis of total radioactivity and metabolite profiling.

Introduction: CA102N is a novel anticancer drug developed by covalently linking H-Nim (N-(4-Amino-2-phenoxyphenyl methanesulfonamide) to Hyaluronic Acid to target CD44 receptor-rich tumors. The proposed approach seeks to enhance the efficacy and overcome limitations associated with H-Nim, including poor solubility and short half-life.
Methods: The study aimed to evaluate the pharmacokinetics, biodistribution, metabolism, and tumor permeability of [14C] CA102N in xenograft mice following a single intravenous dose of 200 mg/kg.

Objective: This study investigated absorption, metabolism, and excretion of adagrasib after a single oral 600 mg dose (1 µCi [C]-adagrasib) in 7 healthy subjects and compared the metabolite profile to the profile at steady-state in 4 patients dosed at 600 mg twice daily.
Methods: Plasma, urine, and feces were collected post [C]-adagrasib administration and total radioactivity and pooled sample metabolite profiles were determined. Adagrasib pharmacokinetics were determined in plasma and urine.
