************************************************************************

It is a pleasure for us to inform you that we can offer you a quality 
and powerful software: MOLGEN is a molecular graphics program for PC 
that provides a variety of features and tools for investigation of the 
structure and properties of organic molecules
  - Graphic output of AMPAC quantum chemistry calculations (frontier 
    orbitals, bond orders, electron density)
  - Database of partition coefficients for the system of n-octanol - water 
    (2500 entries), 3D-structures (1500 entries), molar refractions
  - Searching in the database entering a substructure, including the 
    possibility to update the entries and add new ones
  - Conformation analysis (automatic search of conformers by means of 
    molecular mechanics, output also in the form of conformation maps)
  - Fitting of 3D-structures with respect to their shape, electrostatic 
    or lipophilicity potential
This is only a brief outline of the program capabilities. To obtain a more 
thorough insight, please, copy the demo or ask any information on the 
address given below.
Among comparable software, MOLGEN is available for a very reasonable price: 
Academic - $290, Non-academic - $850.
Allow us to hope that you will find MOLGEN a useful tool in your work. 
We look forward to hearing from you.

Sincerely yours,

Dr. Milan Hudecek

What follows is an outline of new features of version 3.0

Molecular graphics
- automatic determination of centres of optical activity with the 
  possibility of their inversion
- interface to ChemWindow - a widespread editor of 2D-structures
- 2D to 3D automatic convertor utilizing 3D-substructures of 
  implemented database (contains about 1500 optimized structures)
- extension of graphic modes for space fill models depiction:
        VGA(512 kB)     256 colors      640x480
        VGA(1024kB)     256 colors      800x600
        VGA(1024kB)     256colors       1024x768
- internal text editor 

Physicochemical properties
- rapid empirical calculation of atomic charges
- conformationally dependent computing of log(p) (oct-anol/water) 
  and lipophilicity potential

Database
- MOLGEN's database contains experimental values of log(p) (partition 
  coefficients for the system of n-octanol/water) and molar refractivities 
  of about 3400 compounds, and optimized 3D-structures of about 1500 
  compounds.
- The database system provides the user with the possiblility to update 
  the information on stored molecule, add data about new ones, and to 
  search in the database entering a sub-structural unit (substructural 
  search).
