The novel 7-transmembrane receptor MrgX1 is located predominantly in the dorsal root ganglion and has consequently been implicated in the perception of pain. Here we describe the discovery and optimization of a small molecule agonist and initial docking studies of this ligand into the receptor in order to provide a suitable lead and tool compound for the(More)
The determination of DNA sequences by partial exonuclease digestion followed by Matrix-Assisted Laser Desorption Time of Flight Mass Spectrometry (MALDI-TOF) is a well established method. When the same procedure is applied to RNA, difficulties arise due to the small (1 Da) mass difference between the nucleotides U and C, which makes unambiguous assignment(More)
A series of 3-amino-6-aryl-pyridazines have been identified as CB(2) agonists with high efficacy and selectivity against the CB(1) receptor. Details of the investigation of structure-activity relationships (SAR) are disclosed, which led to the identification of pyridazine analogue 35, a compound with high potency in an in vivo model of inflammatory pain.
2-Amino-5-aryl-pyridines, exemplified by compound 1, had been identified as a synthetically tractable series of CB(2) agonists from a high-throughput screen of the GlaxoSmithKline compound collection. Described herein are the results of an investigation of the structure-activity relationships (SAR) which led to the identification a number of potent and(More)
A series of carbapenems containing novel C-2 semisaturated heterocyclic substituents were synthesised by 1,3 dipolar cycloaddition reactions of nitrile oxides, nitrile imines and a nitrone to 2-vinylcarbapenem. The isoxazoline and isoxazolidine compounds showed potent antibacterial activity but moderate stability to human dehydropeptidase 1 (DHP-1).(More)
