The past century has witnessed an exponential increase in our atomic-level understanding of molecular and cellular mechanisms from a structural perspective, with multiple landmark achievements contributing to the field. This, coupled with recent and continuing breakthroughs in artificial intelligence methods such as AlphaFold2, and enhanced computational power, is enabling our understanding of protein structure and function at unprecedented levels of accuracy and predictivity. Here, we describe some of the major recent advances across these fields, and describe, as these technologies coalesce, the potential to utilise our enhanced knowledge of intricate cellular and molecular systems to discover novel therapeutics to alleviate human suffering.

The P2X4 receptor is implicated in various pathological conditions, including neuropathic pain and cancer. This study reports the development of 1,4-naphthodiazepinedione-based P2X4 receptor antagonists aimed at both therapeutic applications and potential use as PET tracers for imaging P2X4 receptor expression in cancer. Structure-activity relationship studies aided by docking studies and molecular dynamics simulations led to a series of compounds with potent P2X4 receptor antagonism, promising inhibition of interleukin-1β release in THP-1 cells and suitability for radiolabeling with fluorine-18.

The glucocorticoid receptor (GR) is present in almost every vertebrate cell and is utilized in many biological processes. Despite an abundance of mammalian data, the structural conservation of the receptor and cross-species susceptibility, particularly for aquatic species, has not been well defined. Efforts to reduce, refine, and/or replace animal testing have increased, driving the impetus to advance development of new approach methodologies (NAMs).

Under extreme conditions, condensed matters are subject to undergo a phase transition and there have been many attempts to find another form of hydroxide stabilized over HO. Here, using Density Functional Theory (DFT)-based crystal structure prediction including zero-point energy, it is that proton superoxide (HO), the lightest superoxide, can be stabilized energetically at high pressure and temperature conditions. HO is metallic at high pressure, which originates from the 𝜋 orbitals overlap between adjacent superoxide anions (O ).

Developing low-cost unipolar n-type organic thin-film transistors (OTFTs) is necessary for logic circuits. To achieve this objective, the usage of new electron-deficient building blocks with simple structure and easy synthetic route is desirable. Among all electron-deficient building units, N-oxide-functionalized bipyridines can be prepared through a simple oxidized transformation of bipyridines.

Defective MOFs have been identified as promising candidates for efficient membrane-based separation applications. However, the utilization of defective MOFs in membrane gas separation is still in its infancy due primarily to the inefficient molecular differentiation induced by structural defects. Herein, we report a strategic combination of ionic liquid (IL) and defective UiO-66-NH MOF to ameliorate the CO/N selectivity within the highly permeable PIM-1 polymer.
