The FDA approval of imatinib in 2001 was a breakthrough in molecularly targeted cancer therapy and heralded the emergence of kinase inhibitors as a key drug class in the oncology area and beyond. Continued advances in the molecular understanding of…

Hot Topics: Soluble ligands as drug targets
Historically, the main classes of drug targets have been receptors, enzymes, ion channels and transporters which are primarily targeted by small molecules. However, advances in molecular biology, genomics, and pharmacology have facilitated the development of different therapeutic modalities which in…
Hot Topics: TMEM163 regulates ATP-gated P2X receptor and behaviour
It is now clear that ligand-gated ion channels (LGICs) are not “stand alone” functional units, but form complexes with other components, including scaffolding proteins, regulatory proteins and enzymes. Besides their important physiological roles, these modulating proteins are also potential targets…
Hot Topics: Virtual screening on the crystal structure of the G protein-coupled melatonin MT1 receptor reveals several new chemical scaffolds with biological activity
Melatonin targets two high-affinity receptors, MT1 and MT2, that belong to the G protein-coupled receptor (GPCR) superfamily (1,2). Drugs acting on melatonin receptors are subscribed for circadian disorders (jet lag, shift work, etc.), insomnia and major depression (3). All marketed…
Hot Topics: Cardiac Ca2+ Channel Regulation in the Fight-or-Flight Response: the monomeric small G-protein as another piece in the puzzle
Thirty eight years after the discovery that injection of the catalytic subunits of cyclic AMP-dependent protein kinase A (PKA) into isolated pig ventricular cardiac myocytes (1) increases the amplitude of L-type Ca2+ current (today known to be formed by Cav1.2…
Hot Topics: A brief update on coronaviruses
The new respiratory coronavirus from Wuhan in China is causing intense research activity in the world. Viruses are evidently associated with respiratory infections ranging in severity from the common cold to pneumonia and death

Hot Topics: Cryo-EM structure of a selective T-type calcium channel blocker bound to the Cav3.1 voltage-gated calcium channel
Nieng Yan’s group has now published the cryo-EM structure of the selective T-type Ca2+ channel blocker Z944 bound to the pore-forming α1-subunit of Cav3.1 T-type Ca2+ channels (1). This nicely adds to recent publications reporting of the high-resolution structures of…

Hot Topics: Deciphering the crystal structure of the leukotriene receptor CysLT2 opens up for improved therapeutics
Leukotrienes are lipid mediators of inflammation, initially recognized for their role in asthma, but also having potent effects in for example cardiovascular and neurological diseases as well as in cancer. The initial pharmacological classification of leukotriene receptors based on antagonist…
Hot Topics: 3D structure of the full-length P2X7 receptor provides insight into factors controlling agonist potency and receptor desensitisation
P2X receptors are ligand-gated cation channels for which ATP is the endogenous orthosteric agonist. Seven P2X subunits have been identified and they form trimers to produce at least twelve different receptor subtypes. The tertiary structure of several subtypes have been…
Hot Topics: Resting-State Structure and Gating Mechanism of a Voltage-Gated Sodium Channel
In this report the Catterall laboratory succeeded in solving the high resolution structure of a voltage-gated Na+-channel (Nav) in its resting state (1). Why is this difficult and why is this important? It is difficult because Navs exist in the…
Hot Topic: Unexplored therapeutic opportunities in the human genome
Contemporary drug discovery is dominated by two related themes. The first of these is target validation upon which the sustainability of pharmaceutical R&D (in both the commercial and academic sectors) crucially depends. The second is the size of the pool of human…
Hot topic: The G Protein-Coupled Receptors deorphanization landscape.
Within the vast GPCR superfamily, orphans are described as receptors devoid of known endogenous ligands. They have been labeled as 7 transmembrane proteins by sequence homology and dispatched accordingly in the different GPCR subfamilies. They have attracted much attention given…
GtoPdb at Pharmacology 2017
The GtoPdb team will be at the British Pharmacological Society’s flagship meeting, Pharmacology 2017, in London, December 11-13th 2017. We are pleased to have our own stand at this meeting and will be present during the refreshment breaks and poster…
The Concise Guide to PHARMACOLOGY 2017/18
Concise Guide to Pharmacology Simplifies Drug Discovery Research The Concise Guide to PHARMACOLOGY 2017/18 (CGTP), which is produced from a subset of the data contained in the IUPHAR/BPS Guide to PHARMACOLOGY database, is now available in the British Journal of…
