Molecular modeling, software

In recent years, the rapid development of low-budget 3D-capablc graphics cards makes it possible to visualize molecular models with standard PC systems. Some molecular modeling software, which was once available only for workstations, is now also offered for PCs [198].

With the widespread commercialization of molecular modeling software in the 1980s, came both a boon and a bane to the computational chemist and pharmaceutical companies. The boon was that the software vendors sent marketing people to individual companies as well as to scientific meetings. The marketeers would extol the virtues of the programs they were pushing.

Nowadays, computers play an important part in the design and development of medicines. For example, molecular modelling software allows chemists to study how potential medicines will interact with receptors in the body and to determine how their structures can be modified to enhance their effect. 

The calculations in the next section were performed using the above methods implemented in MOE molecular modeling software (22). 

The Spartan 02 04 molecular modeling software packages were used to predict the optimized geometry and the NMR spectra. The H-NMR spectra were predicted at the ab initio level using the Hartree-Fock to obtain the equilibrium geometry with the 3-2IG basis set. In a similar manner, we predicted the proton NMR spectra of the absorbed HCl.

Alternately, the commercial molecular modeling software programs such as ChemOffice (http //www.camsoft.com) can be used. The ISIS draw in sketch format (struname.skc) is first converted to ChemDraw format (struname.cdx), which is then transformed into 3D structure (struname.c3d) with Chem 3D (Chapter 14) and saved as PDB format (struname.pdb).
