Exposure‐Response Analyses of Datopotamab Deruxtecan (Dato‐DXd), a TROP2‐Directed Antibody‐Drug Conjugate, in Advanced Non‐small Cell Lung Cancer

Clinical Pharmacology &Therapeutics, EarlyView.
Exposure‐response analyses supported a favorable benefit‐risk profile of Dato‐DXd at 6 mg/kg Q3W in patients with advanced nonsquamous NSCLC. Datopotamab deruxtecan (Dato‐DXd) is a trophoblast cell‐surface antigen‐2 (TROP2)‐directed antibody‐drug conjugate (ADC) that has demonstrated clinical activity in patients with NSCLC who have received prior ...

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Epirubicin Alters Pancreatic Autophagy and Insulin Synthesis Through a Zinc‐Dependent Mechanism

Journal of Applied Toxicology, EarlyView.
ABSTRACT Epirubicin (EPI) can cause metabolic side effects, including chemotherapy‐related diabetes, partly through oxidative stress that disrupts zinc (Zn) homeostasis and impairs autophagy. This study investigated the effects of EPI on Zn regulation and autophagy in the pancreas, as well as the modulatory role of N‐acetylcysteine (NAC). Rats received

Synthesis, Cytotoxicity, and Apoptosis‐Associated Cell Death Activity of an Isatin‐Containing Pyrimidine‐Derived Cu(II) Complex

Journal of Applied Toxicology, EarlyView.
ABSTRACT A Cu(II) complex derived from a pyrimidine with the isatin group was synthesized and tested for its cytotoxic effects on A549 lung cancer and MCF‐7 breast cancer cell lines, as well as its effects on apoptosis‐associated cell death and cell cycle regulation in A549 cells. To evaluate cytotoxicity, MTT assays were performed at 24, 48, and 72 h,

Dual Genotoxic and Antigenotoxic Effects of 3‐Benzoylcoumarins in Mammalian Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Coumarins are phenolic compounds widely recognized for their diverse pharmacological activities and have attracted increasing attention as potential chemopreventive agents. In the present study, four known 3‐benzoylcoumarin derivatives [(1), (2), (3), and (4)] were evaluated for their cytotoxic, mutagenic, and antigenotoxic effects in Chinese ...

New Insights into the Geometry and Topology of DNA Replication Intermediates

Biology
The regulation of superhelical stress, mediated by the combined action of topoisomerases and fork rotation, is crucial for DNA replication. The conformational changes during DNA replication are still experimentally challenging, mainly due to the rapid ...

Targeting bacterial topoisomerases: how to counter mechanisms of resistance

, 2016
DNA gyrase and topoisomerase IV are type IIA bacterial topoisomerases that are targeted by highly effective antibiotics. However, resistance via multiple mechanisms arises to limit the efficacies of these drugs.
