ABSTRACT
|
|
|
| |
|
(-)-Huperzine A (HupA) is found in an extract from a club moss that has been
used for centuries in Chinese folk medicine. Its action has been attributed to
its ability to strongly inhibit acetylcholinesterase (AChE). The crystal
structure of the complex of AChE with optically pure HupA at 2.5 A resolution
shows an unexpected orientation for the inhibitor with surprisingly few strong
direct interactions with protein residues to explain its high affinity. This
structure is compared to the native structure of AChE devoid of any inhibitor as
determined to the same resolution. An analysis of the affinities of structural
analogues of HupA, correlated with their interactions with the protein, shows
the importance of individual hydrophobic interactions between HupA and aromatic
residues in the active-site gorge of AChE.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
codes are
shown on the right.
