Novel Covalent Probe Selectively Targeting Glutathione Peroxidase 4 In Vivo: Potential Applications in Pancreatic Cancer Therapy

Covalent Modifiers

3c01608 Glutathione peroxidase 4 (GPX4) emerges as a promising target for the treatment of therapy-resistant cancer through ferroptosis. However, a majority of reported GPX4 inhibitors utilize chloroacetamide as a reactive electrophilic warhead, and the selectivity and pharmacokinetic properties still need to be improved.

New drug triggers rapid cell death in cancer models

Broad Institute

So the team turned their attention to optimizing the pharmacokinetic profile of BRD-810 to preserve its ability to kill tumor cells without negatively affecting heart cells. Trueline Therapeutics also tested the compound in a canine model and did not detect any markers of cardiac toxicity.

Preclinical systemic pharmacokinetics, dose-proportionality, and CNS distribution of the ATM inhibitor WSD0628, a novel radiosensitizer for the treatment of brain tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

Radiation therapy, a standard treatment option for many cancer patients, induces DNA double strand breaks (DSBs), leading to cell death. The objective of this study was to evaluate the systemic pharmacokinetics and mechanisms that influence the CNS distribution of WSD0628, a novel and potent ATM inhibitor, in the mouse.

Translational pharmacokinetic-toxicodynamic model of myelosuppression for dose optimization in combination chemotherapy of capecitabine and oxaliplatin from rats to humans [Drug Discovery and Translational Medicine]

ASPET

XELOX therapy, which comprises capecitabine and oxaliplatin, is the standard first-line chemotherapeutic regimen for colorectal cancer. Mathematical modeling combining pharmacokinetics (PK) and toxicodynamics (TD) is a promising approach for optimizing dosing strategies and reducing toxicity.

The rising impact of biomarkers in early clinical development

Drug Target Review

As our understanding of the underlying biology of disease grows more sophisticated, emerging therapies operate on increasingly complex biopathological systems and mechanisms. Safety biomarkers account for adverse effects of a therapy under study. There are several types of biomarkers to consider.

Pramlintide an Adjunct to Insulin Therapy: Challenges and Recent progress in delivery [Minireview]

ASPET

However, Pramlintide an adjunct to insulin therapy, enhances glucagon suppression and thereby offers improved glycaemic control. Although clinical benefits of Pramlintide are well reported, there still exists a high patient resistance for the therapy as separate injections for Pramlintide and insulin are required to be administered.

Factors influencing the Central Nervous System (CNS) distribution of the ATR inhibitor elimusertib (BAY1895344): Implications for the treatment of CNS tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

Standard of care GBM therapies include radiation and cytotoxic chemotherapy that lead to DNA damage. Elimusertib, a novel ATR kinase inhibitor, can prevent repair of damaged DNA, increasing efficacy of DNA damaging cytotoxic therapies. Subsequent activation of DNA damage response (DDR) pathways can induce resistance.
