Subject:  PC-BASED MOLECULAR MODELING PACKAGES

Netters:
	First, let me thank all of you that responded to my query regarding
PC-based software for molecular modeling.  Based on these responses, the most
widely used packages at present are ALCHEMY from Tripos, and PCMODEL from
Serena.  Interestingly, the next most frequently mentioned package (HYPERCHEM
from Autodesk) has just been released, and there really hasn't been time for
development of anecdotal information.

	I have organized the material first by product, with user information
separated from vendor information, if any. (ALCHEMY, PCMODEL, & HYPERCHEM are
listed first, with the rest in alphabetical order.)  Next, pointers to reviews
are included, followed by any "general information" at the end.  I hope that
this compendium is useful.

ALCHEMY III - User Info
-------------------------------------------------------------------------
Alchemy III is a fragment model builder using a modified Sybyl or MM3 force
field to do molecular mechanics.
--
>>"GERSON %-% at %-% DFWVM04.VNET.IBM.COM" "Dr. Dennis Gerson"

ALCHEMY is a junior version of SYBYL and has a lot of good capabilities.  It
  runs on both MACs and IBMs.  ALCHEMY (above) is the one with the tie to
Chemical Abstracts.
  This means results of 3D searching can be viewed in ALCHEMY.
--
>>"MARTIN -x- at -x- cmda.abbott.com" "MARTIN%CMDA"

I strongly suggest that you look into ALCHEMY which is distributed by Tripos
(1-800-323-2960).  It's really good and really cheap.
--
>>"PEARLMAN.,at,.VAX.PHR.UTEXAS.EDU"

There's the Alchemy II package from Tripos, which runs on PC's and MAC's,
which have structure building/visualization, and some energy minimzation
for structure refinement.  Energy minimizations are not terribly
sophisticated, but do provide a relatively inexpensive entry into the
modelling world.

  Alchemy from Tripos Assoc.s is slightly more complicated (re: PCMODEL), but
also more sophisticated.  I have only used Alchemy as a loaner
from Tripos during a computational chemistry workshop for under-
graduate professors run by Roger DeKock (deko (+ at +) calvin.edu).

Alchemy-III  Tripos
                       Nice graphics, simple structure building and MM,
                       fitting, interactive torsion adjustment, etc.  Nicely
                       done.  Uses bizarre Tripos file format that's difficult
                       to convert to/from anything else.

 Tripos has Alchemy 3 for PCs - We have used verison 2. and it works for small
(20-50) atom systems.   As for anecdotal information, I have been teaching
modeling at R&H for  10 years now, and I usually hook 1 or 2 scientists each
year.  Recently Tripos Alchemy was the prefferred PC solution, but at the  ACS
meeting I will reevaluate them again.

PCMODEL - User Info
----------------------------------------------------------------------------
PCMODEL is a "line drawing" builder using a modified MMX or Macromodel Force
field to do molecular mechanics.  It also has simple solvent dynamics and
a limited version of conformation searching.  It requires 386/387 or higher
cpus to work well.

>>"GERSON;at;DFWVM04.VNET.IBM.COM" "Dr. Dennis Gerson"

Try PCModel    -  Serena Software, Bloomington, Indiana.
Many features workes well with 150-250 atoms.  Use it all of the
time on my Mac.  It runs on both the Mac and PC.
--
>>"FAX0157.,at,.uoft02.utoledo.edu" "JGANO.,at,.UOFT02 or 537-2104"

I have used PCModel by S[Cerena Software, Box 3076, Bloomington, IN 47420-3076
(Ph 812-333-0823) for some time now and I find it very easy to use.  You need a
math coprocessor, mouse, and 550K of free ram to run.  There are versions for
other platforms also.

                       a PC-version of MM2 and some semi-empirical programs,

The last cost I heard was $250 for academic users, and I think it is about
double that for others.  The program is easy to use and has a lot of features.
You should also get their MMX program to accompany it.

HYPERCHEM - User Info
----------------------------------------------------------------------------
By chance (a friend is applying for a position ...) I've heard that Autodesk
(most famous for their AutoCAD) is just now trying to enter  the market with a
product called "Hyperchem" (or similar). I think my friend's got a  copy to
try, but I didn't have the time yet ...
--
>>"sauer %-% at %-% igc.ethz.ch" "Wolfgang Sauer"

Check out HyperChem, which is just about to be released by Autodesk.  I think
this product will have a significant impact on the community, although it
really requires something like a 486 machine to work well.  I've seen
pretty detailed demos and it looks like a good product.  Availability and
prices should be available by about the end of March from Autodesk.

Can only suggest HyperChem from the folks at AutoDesk (creators of AutoCad).
Looks to be a good package - much more than a toy.

HYPERCHEM - Vendor Info (LOOOONNNGG!!!)
----------------------------------------------------------------------------
Autodesk, Inc will soon be shipping a new Windows-based molecular
modeling package called HyperChem. HyperChem runs on a 386/486 PC under
Microsoft Windows. It includes the capabilties to:
        o Draw molecules in 2D and have a 3D structure automatically
        generated by the built-in Model Builder
        o Import files such as Brookhaven Protein Data Bank files and
        then edit and modify them
        o Create complex proteins and nucleic acids (DNA/RNA) using
        built-in residue templates (custom residues can be added)
        o Visualize structures in stick, sphere, dot surface, stereo and
        other renderings
        o Rotate, translate, Z-plane clip molecules, etc for better
        visualization
        o Calculate structural information such as bond angles, lengths,
        torsion angles, interatomic distances, chirality, etc
        o Label and display information such as atom type, charge,
        residues/sequence, backbones, etc
        o Put constraints on specific bond lengths, angles, torsions
        o Do geometry optimization and single point energy calculations
        using four different Molecular Mechanics force fields
        o Calculate and plot electronic properties such as total charge
        density, electrostatic charge density, spin density and
        individual atomic orbitals using six different semi-empirical
        quantum mechanical methods
        o Do Molecular Mechanics or Semi-empirical quantum calculations
        on selected areas of a structure
        o Do Molecular Dynamics simulations using either Molecular
        Mechanics or Semi-Empirical methods.
        o Solvate molecules in a periodic box and then run any of the MM
        or SEQM analyses on the system
        o Customize and extend HyperChem through a built-in scripting
        language by writing scripts to automate tasks and experiments,
        interacting with other Windows programs such as Excel, or by
        writing custom applications with programs such as Microsoft
        Visual Basic that look and act like a built-in function of
        HyperChem

------------------------------------------------------------------------------
I saw your note on the OSC chemistry e-mail group concerning molecular
modeling software on the PC.  I work for Hypercube, and we are the
developers of Autodesk's HyperChem, which is just such a package.
HyperChem is to be released any day now: it just went to production
yesterday.

I won't be able to give you an outsider's view of HyperChem, of course,
but in brief what it does is the following:

(1)	It runs under Microsoft Windows, and has capability to exchange
information with other applications (spreadsheets, wordprocessors, etc.),
via DDE and through the WIndows clipboard.
A Silicon Graphics version is due for release later this year.

(2)	It contains a graphical front end that enables molecules to be
drawn easily (there is a model-building capability that produces 3D
structures from rough sketches).  It has an extensive range of
facilities for manipulation and display of molecules.  Proteins and DNA
fragments can be built residue-by-residue in a particularly easy manner.

(3)	It contains four molecular mechanics force fields: MM+ (our
implementation of MM2, with a default scheme to fill in the gaps in
parameters), OPLS, AMBER and BIO+ (our implementation of the CHARMM
force field, including the published parameters).

(4)	Using these force fields, geometry optimizations on all or part
of a system can be carried out, using constraints where needed.

(5)	Using these force fields, molecular dynamics calculations can be
carried out, again on all or part of a system and with or without
constraints.  There are playback tools for analysis of molecular
dynamics runs, and geometrical features as well as energies can be
monitored during a run.

(6)	It contains our implementation of six semi-empirical methods.
Extended Huckel, CNDO, INDO, MINDO/3, MNDO and AM1.  PM3 parameters are
available for the latter option.  Geometry optimizations can be carried
out using these methods (except for Extended Huckel), and also molecular
dynamics (if you have the time to wait!).  CNDO and INDO calculations
can also be carried out on part of a system, with the remainder serving
as an electrostatic background.

(7)	All the molecular mechanics and semi-empirical parameters are
available in files, and can be added to and changed by the user.

(8)	There is an extensive set of scripting (macro) commands, that
can be run as scripts from within the program or built into macros from
other Windows applications.
via DDE.

	Should you require any other technical information, please
do feel free to contact me.  Autodesk has a product information line at
1-800-424-9737, or you can FAX them at 1-415-491-8311.

MACMIMIC - Vendor Info
----------------------------------------------------------------------------
I am the author of MacMimic, a molecular modeling package that
runs on Macintosh II and Macintosh Quadra computers.

Some advantages of MacMimic:

o MacMimic is a complete Macintosh program;
  It can handle multiple structures in multiple windows.
  It prints on any color or laser-printer connected to the Macintosh.
  You may Undo the last structural change. Etc.
o MacMimic has a powerful structure editor.
o MacMimic has built in chemical knowledge. Newly constructed models
  are generally close (1-3 kcal/mol) to their local MM2 minima.
o MacMimic includes an authentic implementation of the molecular
  mechanics program MM2(91). To the best of my knowledge there is
  currently no other authentic implementations of MM2(91) for
  personal computers.
o All computational options of MM2 such as dihedral drivers and
  restricted motions have a user-friendly interface.
o MM2(91) has been expanded to handle 200 atoms and 80 PI-atoms.
o MM2(91) allows you to minimize a batch of structures.
o MacMimic is continuously being improved. We are currently working
  on a Macintosh implementation of MM3 and an interface to MOPAC
  (and maybe MOPAC itself).

MacMimic is used routinely by most of the Scandinavian pharmaceutical
industry. Furthermore, MacMimic is used by academic institutions and
industries in USA, Japan, Canada, and in several European countries.

I have sent some further information on MacMimic in a separate letter,

GENERAL INFORMATION - RECOMMENDED REVIEWS
-------------------------------------------------------------------------
regarding molecular modeling on a PC.....
There is a review article on this topic in Jour. CAMD, 2,(1988),81-90,
by Sadek & Munro. I am also aware of a large BASIC program in the book;
"Computational Chemistry; An Emphasis on Practical Solutions" by Milton Johnson,
Elsevier,1988.  These are 2 places for you to look.

	I recently saw a message from you that appeared on the OSC bulletin
board about PC based Molecular Modelling packages.  I know of several but have
no real extensive experience with them.  Some are: Chem3D (Mac based), MOBY (
PC) based, and PC-Model.  However Phil Bayes just finished a sabatical year
at UNC-Chapel Hill specifically evaluating PC based Molecular Modelling
packages.  His e-mail address is "pbays &$at$& bach.helios.nd.edu". (SEE BELOW -

I have a review of five programs for the Mac which appears in the
March (1992) issue of J. Chem. Ed.  I have not yet received my copy,
but I understand that it is out.  I have subsequently received
an updated version of Chem3D Plus.  I would suggest that you
use that article as a starting point.....

GENERAL INFORMATION - PKGS MENTIONED W/O COMMENT
-------------------------------------------------------------------------
  A program you may wish to consider is the "Promodeler" package from
New England BioGraphics (1-802-633-4344). It is specifically designed for
macromolecules. Let me know if you have any technical questions about
specific capabilities.

There are a number of packages available on PCs. I am more familiar with Mac
programs because I don't have an IBM clone.
1) Alchemy by Tripos
2) Nanovision by ACS software
3) Chem 3D ????
4) In addition, there are a number of shareware packages that I don't keep
track of. Macmolecule seems to ring a bell for one of them. I know that one
comes out of a group from Sweden.

The best place to find a list of molecular modeling software that runs on PCs
would be the Appendices in Volumes 1 and 2 of Reviews in Computational
Chemistry.  Don Boyd has written these appendices.  (SEE BELOW - FAV)  In
addition to the items that he has tabulated you should add Hyperchem, the new
release from Autodesk, Inc.  They have run two page ads in Science and in C&EN
in the past few weeks and this week they are making their public announcement.
You can reach Autodesk at (800) 424-9737.

please append them to this file.
