Abstract
Classical hydrocarbon scaffolds have long assisted in bringing new molecules to the market for a variety of applications, but one notable omission is that of tetraasteranes, which are homologues of cubanes belonging to a class of polycyclic hydrocarbon cage compounds. Tetraasteranes exhibit potential as scaffolds in drug discovery due to their identical cyclobutane structures and rigid conformation resembling cubanes. Based on the studies of the physical and chemical properties of tetraasteranes by density functional theory, three series of compounds were designed as homologues of cubanes by the substitution of cubane scaffolds in pharmaceuticals with tetraasteranes. Their potential for pharmaceutical applications was evaluated in silico by molecular docking and dynamics simulations. Their pharmacokinetic and physicochemical properties were studied by the ADMET (absorption, distribution, metabolism, excretion, and toxicity) analysis. The results indicate that tetraasteranes may be scaffolds as novel bioisosteres of cubanes, as well as hydrogen bond donors or acceptors, which enhance the affinity between ligands and receptors with more stable binding behavior and feasible tolerability in ADMET. All these findings provide new opportunities for tetraasteranes to serve as effective pharmaceutical scaffolds for drug discovery and to accelerate the drug discovery process by repurposing both new and old commercial compounds.

Abstract
Cubane is a highly strained saturated hydrocarbon system that has historically been of interest in theoretical organic chemistry. More recently it has become a molecule of interest for biological applications due to its inherent stability and limited toxicity. Of greater significance is the ability to potentially functionalize cubane at each of its carbon atoms, providing complex biologically active molecules with unique spatial arrangements for probing active sites. These characteristics have led to an increased use of cubane in pharmaceutically relevant molecules. In this Perspective we describe synthetic methodology for accessing a range of functionalized cubanes and their applications in pharmaceuticals. We also provide some perspectives on challenges and future directions in the advancement of this field.

Abstract
The A1 adenosine receptor (A1AR) is an important G protein-coupled receptor that regulates a range of physiological functions. Herein we report the discovery of novel irreversible agonists acting at the A1AR, which have the potential to serve as useful research tools for studying receptor structure and function. A series of novel adenosine derivatives bearing electrophilic substituents was synthesized, and four compounds, 8b, 15a, 15b, and 15d, were shown to possess similar potency and efficacy to the reference high efficacy agonist, NECA, in an assay of ERK1/2 phosphorylation assay. Insensitivity to antagonist addition in a real-time, label-free, xCELLigence assay was subsequently used to identify compounds that likely mediated their agonism through an irreversible interaction with the A1AR. Of these compounds, 15b and 15d were more directly validated as irreversible agonists of the A1AR using membrane-based [3H]DPCPX and [35S]GTPγS binding experiments.
