We optimized our highly potent and cell-active chemical probe for phosphatidylinositol-3-phosphate 5-kinase (PIKfyve), SGC-PIKFYVE-1, resulting in compounds with improved potency and demonstrated stability. Use of an in-cell, kinome-wide selectivity panel allowed for confirmation of excellent in-cell selectivity of our lead compound, , and another promising analogue, . Evaluation of the pharmacokinetic (PK) profiles of these two compounds revealed that both are well tolerated systemically and orally bioavailable.

Objective: Adverse childhood experiences (ACE) have inconsistently been implicated as risk factors for immune-mediated inflammatory diseases (IMID). We evaluated whether the association of ACE with disease differs between IMID and other chronic diseases.
Design: Nested retrospective case-control study.

Understanding cytokine-related therapeutic protein-drug interactions (TP-DI) is crucial for effective medication management in conditions characterized by elevated inflammatory responses. Recent FDA and ICH guidelines highlight a systematic, risk-based approach for evaluating these interactions, emphasizing the need for a thorough mechanistic understanding of TP-DIs. This study integrates the physiologically based pharmacokinetic (PBPK) model for TP (specifically interleukin-6, IL-6) with small-molecule drug PBPK models to elucidate cytokine-related TP-DI mechanistically.

Hidradenitis suppurativa is a chronic inflammatory disease of the skin with a suppurative-cicatricial outcome affecting the infundibular component of the pilo-sebaceous unit. The lesions are typically localized in the intertriginous and apocrine gland-rich areas. Hidradenitis suppurativa mainly affects patients at a young age and is very often refractory to conventional medical treatment.

Background & Objective: IBD fatigue aetiology is poorly understood. This study quantified body composition and physical function alongside proton magnetic resonance imaging (1H MRI) and spectroscopy (31P MRS) measures of organ structure and function in quiescent Crohn's Disease patients (CD) and healthy volunteers (HV), to identify a physiological basis for IBD fatigue.
Methods: Body composition was determined using DEXA and 1H MRI.
