Ulcerative colitis (UC) is a severe and debilitating illness that affects the quality of life and physical health of many Canadians. Given the dynamic and progressive nature of the disease, advanced therapies are required to support its long-term management. The emergence of small molecule therapies offers novel treatment options that target mechanisms central to the immunopathology of UC. Sphingosine-1-phosphate (S1P) receptor modulators and Janus-activated kinase inhibitors are 2 classes of therapies that target unique pathways to attenuate inflammation and modulate the immune response characteristic of UC. This review aims to provide practical guidance on how these therapeutic options can best be used to optimize treatment management and highlight the emerging role of small molecule therapies as a treatment strategy for UC.

Sorafenib, a clinically approved multityrosine kinase inhibitor, exhibits poor aqueous solubility, which limits its bioavailability and therapeutic efficacy. In this study, we introduce a solvent-directed self-assembly strategy to modulate the nanostructure of sorafenib without the use of external carriers or complex formulation techniques. In pure water, sorafenib forms large lamellar aggregates, whereas in 30% methanol-water mixtures, it self-assembles into uniform spherical particles approximately 450 nm in diameter.

Secreted frizzled-related protein 4 (sFRP4) plays a fundamental role in the regulation of Wnt signalling, which is crucial for cellular proliferation and differentiation. The sFRP4 has garnered significant interest as a therapeutic target for metabolic diseases and cancer due to its mechanism of action. Although existing sFRP4 modulators show limited specificity and notable off-target effects, our study explores the potential of known bioactive compounds as more selective and less toxic alternatives.

Electrolytes are important components in lithium-ion batteries. However, battery degradation due to irreversible electrochemical reactions in the electrolyte can consume electrolyte molecules and severely reduce its effective operation lifetime. It is hence important to study the electrochemical reaction pathways in the battery electrolyte to further improve lithium-ion battery reliability.

Investigation of the small molecule-aptamer interaction is difficult, and it usually lacks information about the conformational change of aptamers that is important for their application. Here, we present the label-free investigation of small molecule-aptamer interactions using a modularized organic electrochemical transistor (OECT) platform. Leveraging the high sensitivity of the OECT, we measured the conformational change of the aptamer encountering its ligand.

Advances in molecular analysis and characterization techniques should revolutionize the methods for scientific exploration across physics, chemistry, and biology, fundamentally overturning our understanding of interactions and processes that govern molecular behavior at the microscopic level. Currently, the absence of a molecular analysis method that can both quantify molecules and achieve single-molecule spatial resolution hinders our study of complex molecular systems in sorption and catalysis. Here, we propose a quantitative analysis strategy for small molecules confined in ZSM-5, a zeolite material extensively used in catalysis and gas separation, based on low-dose transmission electron microscopy.
