Abstract:
The so called 'fragment approach' was applied in the search for new leads as selective hNK(2) antagonists. A first round of structural space exploration through the use of bond rigidity as scaffold to support the fragments, afforded 27a as 200 nM hNK(2) ligand. Further refinement gave MEN 14933 as a 16 nM hNK(2) ligand, selective versus hNK(1), of a novel class. Conformational analysis was used to study results and plan future work.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
