There is a lot of confusion over the meaning of the terms theoretical chemistry, computational chemistry and molecular modelling. Indeed, many practitioners use all three labels to describe aspects of their research, as the occasion demands "Theoretical chemistry is often considered synonymous with quantum mechanics, whereas computational chemistry encompasses not only quantum mechanics but also molecular mechaiucs, minimisation, simulations, conformational analysis and other computer-based methods for understanding and predicting the behaviour of molecular systems. Molecular modellers use all of these methods and so we shall not concern ourselves with semantics but rather shall consider any theoretical or computational tecluiique that provides insight into the behaviour of molecular systems to be an example of molecular modelling. If a distinction has to be...

Paluchowska et al. (2002) reported the synthesis, pharmacological studies, and conformational analysis utilizing classical molecular modeling approaches of some arylpiperazine or 1,2,3,4-tetrahydroisoquinoline derivatives of the known and flexible 5-HT ia receptor ligands with different intrinsic activities at nanomolar levels [63]. The SAR is shown in Table 4. The synthetic steps involved for some of the compounds mentioned in Table 4 are shown in Scheme 2 [63].
