N-substituted 3, 4-fullero pyrrolidine was synthesized according to 1, 3-dipolar cycloaddition of the azomethine ylide. Aspartic acid with protected α-amino and α-carboxyl groups was reacted with the activated hydroxyl group of N-substituted 3, 4-fullero pyrrolidine. The products were deprotected, affording the monofullerene aspartic acid (mFas). The conjugate FasT was synthesized by reaction of mFas containing protected amino group with the thymidylic acid derivatived controlled pore glass (CPG) using solid phase synthesis. All of the above fullerene derivatives were characterized by UV–vis, 1H NMR, IR and MS spectrometric analysis, giving the correct spectra with regard to their chemical structure. The chemical structures of fullerene nucleotides conjugate FasT is different from previous reports and may have novel biological properties. Moreover, they are more suitable for applications in biomedical research due to their solubilization in THF and DMSO. They have a potential to be used as monomer for the automatic synthesis. It allows further conjugation with specific biomolecules including amino acids, peptides, nucleotides and nucleic acids. A novel method has been developed to synthesize fullerene nucleotides conjugate. Their unique chemical structures make them very interesting for their potential use in medicine and biology.

Vasopressin Analogues

Solid phase synthesis methodology on a benzhydrylamine resin was used for the synthesis of three analogues of vasopressin with the non-coded amino acid, 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (Tic), in the position 2 ([Tic2, Lys8]VP (I)) and in the position 3 ([Tic3, Lys8]VP (II)). The analogue containing only one Tic in place of both aromatic residues was also isolated (des-Tyr2-[Tic3, Lys8]VP (III)). The biological activities of all analogues were negligible.

Privileged Class

Peptidomimetics are a privileged class of pharmacophores that exhibit improved physicochemical and biological properties. Solid-phase synthesis is a powerful tool for gaining rapid access to libraries of molecules from small molecules to biopolymers and also is widely used for the synthesis of peptidomimetics. Small molecules including heterocycles serve as a core for hundreds of drugs, including peptidomimetic molecules. This review covers solid-phase synthesis strategies for peptidomimetics molecules based on heterocycles.
