Bulky-yet-flexible carbene ligands and their use in palladium cross-coupling [PDF]
In recent years, several classes of new N-heterocyclic carbene (NHC) ligands were developed around the concept of flexible steric bulk. The steric hindrance of these ligands brings stability to the active species, while ligand flexibility still allows ...

Improvement of diaphragm and limb muscle isotonic contractile performance by K+ channel blockade
The K+ channel blocking aminopyridines greatly improve skeletal muscle isometric contractile performance during low to intermediate stimulation frequencies, making them potentially useful as inotropic agents for functional neuromuscular stimulation ...

Neuroprotective Properties of 4-Aminopyridine [PDF]
As an antagonist of voltage-gated potassium (Kv) channels, 4-aminopyridine (4-AP) is used as symptomatic therapy in several neurologic disorders. The improvement of visual function and motor skills and relieve of fatigue in patients with MS have been attributed to 4-AP.

One-pot synthesis of tetracyclic fused imidazo[1,2-a]pyridines via a three-component reaction
A novel three-component reaction has been developed to assemble biologically and pharmaceutically important tetracyclic fused imidazo[1,2-a]pyridines in a one-pot fashion utilizing readily available 2-aminopyridines, isatins and isocyanides.
