Synthesis and properties of cyclopropane-derived peptidomimetics

Article Abstract:

There is widespread interest in designing peptidomimetics and introducing them as replacements of portions of native peptides to enhance the biological properties. Hence, trisubstituted cyclopropaes are invented as novel peptidomimetics, anticipating that the cyclopropane ring would locally orient the backbone and the corresponding amino acid side chain in the biologically active conformation.

Photophysics and photochemistry of pterins in aqueous solution

Article Abstract:

Fluorescence emission, the photooxidation, and the photosensitizing properties of oxidized six-substituted pterins in aqueous solution under UV-A irradiation were described. It was observed that pterins under UV-A radiation could fluoresce, undergo photooxidation to produce different photoproducts, generate reactive oxygen species and photosensitize the oxidation biomolecules.
