Solid Phase Synthesis of Novel Fullerene Nucleotides Conjugates

N-substituted 3, 4-fullero pyrrolidine was synthesized according to 1, 3-dipolar cycloaddition of the azomethine ylide. Aspartic acid with protected alpha-amino and alpha-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, H-1 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.
