Structural Asymmetry of Phosphodiesterase-9A and a Unique Pocket for Selective Binding of a Potent Enantiomeric Inhibitor.

abstract：:The successful synthesis of dolastatin 11, a depsipeptide originally isolated from the mollusk Dolabella auricularia, permitted us to study its effects on cells. The compound arrested cells at cytokinesis by causing a rapid and massive rearrangement of the cellular actin filament network. In a dose-and time-dependent ...

abstract：:N-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induces Parkinson-like symptoms in humans, nonhuman primates, and mice. Several studies suggest that MPTP is metabolized by monoamine oxidase (MAO) type B to yield N-methyl-4-phenyl-pyridinium (MPP+), which is responsible for the neurotoxic effects of the drug. In th...
