Amber94 force field parameters for Saquinavir, Indinavir

[Michiel Jan Laurens de Hoon <mdehoon<<at>>ims.u-tokyo.ac.jp>]

 Hi,
I am using Konrad Hinsen's Molecular Modeling Toolkit to estimate
 changes caused by mutations in the HIV genome in the binding energy
 between the HIV protease and the Indinavir and Saquinavir protease
 inhibitors.  Using Modeller, I can create PDB files with the estimated
 structure of a mutated HIV protease complexed to the protease.  To
 calculate the interaction energy, I would need the Amber94 force field
 parameters for the inhibitor.  Are such parameters available somewhere?
  I didn't find them on the Amber web site, though I would think that
 Indinavir and Saquinavir are well-studied molecules.  Is it possible to
 mock up the interaction between the protease and the inhibitor?
 Something quick and dirty is fine for what I am doing.
 Many thanks in advance,
