Hi All,
I am looking for the parameter and topology files for some ligands,
agonist and antagonist
for nicotinic receptors I want to simulate with NAMD: acetylcholine,
nicotine, lobeline.
I see that acetylcholine (and nicotinamide..) are available in the
CHARMM top/par files, but still I miss lobeline:
http://en.wikipedia.org/wiki/Lobeline
Does anyone has an idea where can I find them, or from where I can build
them?
Thanks a lot in advance,
Grazia
