Discovery and Structure–Activity Relationship Studies of Novel Adenosine A1 Receptor-Selective Agonists

Ladds Group

Published September 19th, 2022


A series of benzyloxy and phenoxy derivatives of the adenosine receptor agonists N6-cyclopentyl adenosine (CPA) and N6-cyclopentyl 5′-N-ethylcarboxamidoadenosine (CP-NECA) were synthesized, and their potency and selectivity were assessed. We observed that the most potent were the compounds with a halogen in the meta position on the aromatic ring of the benzyloxy- or phenoxycyclopentyl substituent. In general, the NECA-based compounds displayed greater A1R selectivity than the adenosine-based compounds, with N6-2-(3-bromobenzyloxy)cyclopentyl-NECA and N6-2-(3-methoxyphenoxy)cyclopentyl-NECA showing ∼1500-fold improved A1R selectivity compared to NECA. In addition, we quantified the compounds’ affinity and kinetics of binding at both human and rat A1R using a NanoBRET binding assay and found that the halogen substituent in the benzyloxy- or phenoxycyclopentyl moiety seems to confer high affinity for the A1R. Molecular modelling studies suggested a hydrophobic subpocket as contributing to the A1R selectivity displayed. We believe that the identified selective potent A1R agonists are valuable tool compounds for adenosine receptor research.

Human mesenchymal stem cells and derived extracellular vesicles reduce sensory neuron hyperexcitability and pain behaviors in murine osteoarthritis

Smith Group

Published October 21st, 2022


Mesenchymal stem cells (MSCs) induce pain relief in humans with osteoarthritis (OA), but their ability to modulate neuronal function is unclear. In this study, it is shown that MSCs and MSC extracellular vesicles (MSC-EVs) ameliorate pain in a mouse model of OA without altering joint pathology. Furthermore, the OA-induced hyperexcitability of knee-innervating neurons was found to be counteracted by MSC/MSC-EV treatment. Nerve growth factor (NGF) is a key player in OA-induced pain and in vitro MSC-EVs prevented NGF sensitisation of sensory neurons. Future work will focus on identifying the mechanisms by which MSC-EVs regulate neuronal excitability.

A multiparametric anti-aging CRISPR screen uncovers a role for BAF in protein translation

Larrieu Group

Posted October 7th, 2022


This study reports the results of what we believe to be the first multiparametric, whole genome anti-ageing CRISPR screen, using progeria patient cells. Through this screen, we have successfully identified 43 genes out of 19,200 whose deletion reversed a combination of specific progeroid cellular phenotypes, opening up new perspectives for understanding the cell biology of ageing, and also offering exciting new opportunities for drug-development.
