  We report the synthesis and theoretical investigations of three novel
pseudo-peptide molecules derived from 2-amino-2-(1H-indole-2-yl) acetamides.
The compounds were subjected to spectroscopic characterization ($^1$H,
$^{13}$C-NMR and MS) and their chemical, electronic, and optical properties
have been investigated. To ascertain their potential pharmacological
applicability, the prospective reactive centers and molecular sites prone to
interaction with water were identified along with possible sensitivity to
autoxidation. Further, we have studied the optical response in the presence of
different solvents and compared the electronic and optical properties of the
pristine molecules. We highlight the subtle dependence of the properties on the
structure and composition of these pseudo-peptides. Our results indicate that
these molecules have high pharmaceutical potential and could serve as lead
components in new drug formulations.
