Abstract: Based on our contemporary studies on the structures
of biologically active molecules, we focus our attention on the aliphatic
chain and its conformation. That flexible spacer definitely influenced
the balanced position of all pharmacophoric points in molecules of bi-
ological ligands. The one atomic linker and two or three atomic spacers
with one heteroatom X =O, S, CH2, NH have been taken into
account. The conformational preferences clearly depend on the heteroatom
X. In the discussion, we utilize our own X-ray data, computation chemistry
methods, population analysis, and statistical data from the Cambridge
Structural Database (CSD).
