RNAs are remarkably versatile molecules that can fold into intricate three-dimensional (3D) structures to perform diverse cellular and viral functions. Despite their biological importance, relatively few RNA 3D have been solved, our understanding of structure-function relationships remains in its infancy. This limitation partly arises from challenges posed by RNA's complex conformational landscape, characterized structural flexibility, formation multiple states, a propensity misfold. Recently, cryo-electron microscopy (cryo-EM) has emerged as powerful tool for the visualization conformationally dynamic RNA-only structures. However, characteristics continue pose challenges. We discuss experimental methods developed overcome these hurdles, including engineering modular modifications facilitate small RNAs, improve particle alignment, validate models.

Abstract Fragment‐based drug discovery (FBDD) is a crucial strategy for developing new drugs that have been applied to diverse targets, from neglected infectious diseases cancer. With at least seven already launched the market, this approach has gained interest in both academics and industry last 20 years. FBDD relies on screening small libraries with about 1000–2000 compounds of low molecular weight (about 300 Da) using several biophysical methods. Because reduced size compounds, chemical space diversity can be better explored than large used high throughput screenings. This review summarises most common techniques fragment orthogonal validation. We also explore advantages drawbacks different examples applications strategies.

Aquaporins (AQPs) are a family of transmembrane water channels expressed in all living organisms. AQPs facilitate osmotically driven flux across biological membranes and, some cases, the movement small molecules (such as glycerol, urea, CO2, NH3, H2O2). Protein–protein interactions play essential roles protein regulation and function. This review provides comprehensive overview current knowledge AQP interactomes addresses molecular basis functional significance these protein–protein health diseases. Targeting may offer new therapeutic avenues targeting individual remains challenging despite intense efforts.
