The efficacy of quinazoline-based antiglioma agents has been attributed to their effects on microtubule dynamics. The design, synthesis and biological evaluation of quinazolines as potent inhibitors of multiple intracellular targets, including microtubules and multiple RTKs, is described. In addition to the known ability of quinazolines 1 and 2 to cause microtubule depolymerization, they were found to be low nanomolar inhibitors of EGFR, VEGFR-2 and PDGFR-β. Low nanomolar inhibition of EGFR was observed for 1-3 and 9-10. Compounds 1 and 4 inhibited VEGFR-2 kinase with activity better than or equal to that of sunitinib. In addition, compounds 1 and 2 had similar potency to sunitinib in the CAM angiogenesis assay. Multitarget activities of compounds in the present study demonstrates that the quinazolines can affect multiple pathways and could lead to these agents having antitumor potential caused by their activity against multiple targets.

Maintaining a healthy pool of circulating red blood cells (RBCs) is essential for adequate perfusion, as even minor changes in the population can impair oxygen delivery, resulting in serious health complications including tissue ischemia and organ dysfunction. This responsibility largely falls to specialized macrophages in the spleen, known as red pulp macrophages, which efficiently take up and recycle damaged RBCs. However, questions remain regarding how these macrophages are acutely activated to accommodate increased demand.

Migraine is a complex neurological disorder involving multiple neuropeptides that modulate nociceptive and sensory pathways. The most studied peptide is calcitonin gene-related peptide (CGRP), which is a well-established migraine trigger and therapeutic target. Recently, another peptide, pituitary adenylate cyclase-activating polypeptide (PACAP), has emerged as an alternative target for migraine therapeutics.

Kinesin family member 14 (KIF14) has been implicated in the progression of multiple cancer types, yet its role in colorectal cancer (CRC) metastasis remains undefined. Here, we assesse KIF14 expression in CRC specimens and explore its clinical and functional significance. KIF14 upregulation is frequently observed in CRC tissues and is correlated with advanced tumor stage and reduced overall survival.

Background And Hypothesis: The dysconnectivity hypothesis of schizophrenia suggests that atypical neural communication underlies the disorder's diverse symptoms. Building on this framework, we propose that specific synaptic disturbances within thalamo-cortical circuits contribute to an imbalance in excitation and inhibition, leading to alteration in oscillations. Our study investigates these alterations and explores whether synaptic restoration can remediate neural activity of schizophrenia and align it with healthy patterns.

Background: The susceptibility values of the basal ganglia reflect the health status of these nuclei. We aimed to explore the associations between various demographic characteristics, lifestyle factors, and biological factors that have the potential to contribute to magnetic susceptibility and investigate the comprehensive impact of these multiple factors on basal ganglia susceptibility values.
Methods: We included 25,980 participants from the UK Biobank.
