Amber parameters and charges

 I hope that this message will be readable
 Dear colleagues,
 I am currently testing several forcefields for minimization of drug-like
 molecules.
 These forcefields are CVFF, CFF91, TRIPOS and AMBER as implemented in
 SYBYL 6.3. For all the molecules under study, AMBER parameters or charges
 are missing.So can you tell me whether there is any library of AMBER
 parameters
 and charges ? At this point, I can mention that several groups have recently
 published AMBER parameters for some cofactors. In addition, use of the AMBER
 forcefield
 in ligand docking studies has been documented, see  for instance the
 abstracts of the Molecular Graphics Society Meeting held in York (September
 1996) but with no details on parameters anc charges.
 Thanking you in advance for the attention you will pay to this query. I will
 send a
 summary of the replies,
 Sincerely,
