An effective solid phase synthesis of Argifin, providing subsequent access to effective synthesis of analogues, was developed in 13% overall yield, as well as elucidating structure-activity relationships. The novel acyclic peptide 18b, prepared from a synthetic intermediate of Argifin, was found to be 70 times more potent as an inhibitor of Serratia marcescens chitinases B than Argifin itself.

Background: Tumour hypoxia resulting from inadequate perfusion is common in many solid tumours, including prostate cancer, and constitutes a major limiting factor in radiation therapy that contributes to treatment resistance. Emerging research in preclinical animal models indicates that exercise has the potential to enhance the efficacy of cancer treatment by modulating tumour perfusion and reducing hypoxia; however, evidence from randomised controlled trials is currently lacking. The 'Exercise medicine as adjunct therapy during RADIation for CAncer of the prostaTE' (ERADICATE) study is designed to investigate the impact of exercise on treatment response, tumour physiology, and adverse effects of treatment in prostate cancer patients undergoing external beam radiation therapy (EBRT).

Salivary cytokines have the potential to serve as biomarkers for evaluating cancer progression and treatment response in specific cancer types. This study explored salivary cytokine profiles in pediatric cancer patients and healthy controls, examining changes during chemotherapy. We conducted a prospective study involving newly diagnosed cancer patients and healthy controls under 19 years old.

Background: Disruption of cyclin D-dependent kinases (CDKs), particularly CDK4/6, drives cancer cell proliferation via abnormal protein phosphorylation. This open-label, single-arm, phase Ib/II trial evaluated the efficacy of the CDK4/6 inhibitor, abemaciclib, combined with paclitaxel against CDK4/6-activated tumors.
Patients And Methods: Patients with locally advanced or metastatic solid tumors with CDK4/6 pathway aberrations were included.

Efficient enrichment of analytes and purification of matrices are crucial for the highly sensitive detection and monitoring of pesticides in traditional Chinese herbs. This work prepared magnetic ionic liquid-controlled covalent organic framework (IL-COF@FeO) as the sorbent via a simple in-situ precipitation polymerization and thiolene "click" strategy. The IL-COF@FeO exhibited remarkable adsorption performance towards pyrethroids within 5 min.
