Main research topics:

  1. Interactions of water-soluble porphyrins with biomolecules: Interaction between porphyrins and biomolecules is a very studied topic owing to the clinical use of these macrocycles in the cure of cancer by photodynamic therapy. Porphyrins are ideal chiroptical reporters because; i) their absorption is far from the region where bases and aminoacids absorbs light and ii) they are not chiral, then even a small induced CD signal is already an useful indication of the DNA structure. In particular, I am studing the interaction of porphyrins with different non-canonical nucleic acid conformations (Z-DNA and G-quadruplex) and proteins (Proteasome).
  2. Template-aided non-covalent syntheses of (chiral and achiral) supramolecular systems: Multi-metalloporphyrin systems have been extensively investigated for their numerous applications as supramolecular devices (e.g. as antennasystems). We induce self-aggregation of water-soluble porphyrins leading to species having a well-defined and tunable stoichiometry. An extension of this work led to an unprecedented, simple non-covalent synthesis (in aqueous solution) of multi-porphyrin complexes for which it is possible to manipulate both the stoichiometry and the sequence. This type of noncovalent synthesis presents the same “accuracy” of thecovalent approach, and a 100% yield, but it is not as time-consuming as the latter method

My research activity started with experiments on porphyrins self-assembly in aqueous solution, continuing the previous works of Prof. Purrello on induction and memorization of chirality on porphyrin aggregates using polymeric chiral templates, to design on-off switch of chiral memory. In particular exploiting inertness and self-catalytic growth of porphyrin hetero-aggregates (J. Am. Chem. Soc., 130, 10476-10477, 2008) and substituting the four permanent charges in the periphery of the cationic porphyrins with four inducible charges (by protonation) we were able to disassembly and reassembly the aggregates allowing for cyclically erasing and rewriting the chiral memory of the imprinted aggregates (J. Am. Chem. Soc., 129, 8062-8063, 2007). We have shown that also inorganic chiral complexes (in our case the ruthenium(II) complexes) can cast chirality in porphyrin aggregates and this pave to way to hybrid organic-inorganic supramolecular complexes in which in addition to chirality it is possible transfer energy or electrons (Angew. Chem. Int. Ed., 47, 9879-9882, 2008). Also these complexes retain memory of the chirality imprinted from the inorganic mold and, also in this case, chirality can be cyclically switched on and off.

This approach using polymeric chiral template did not allow to control some important properties such as molecular stoichiometry and sequence. I obtained this result using as template calixarenes. Extending our investigations on these systems using bis-calixarenes I demonstrated that it is, indeed, possible to choose between aggregates grown in the x,y or x,y,z dimensions. Also in this case, we have the perfect control of sequence and stoichiometry and we can assemble 33 molecular “pieces” in about 10 hours, with a yield higher than 90% (Chemistry-A European Journal, 16, 10439-10446, 2010). In that work we found that a calixarene-mediated porphyrin–porphyrin electronic communication is occurring. This finding allowed us, to succeed in accomplishing the final goal by getting the control over the chirality of the porphyrin assemblies, both by a pure covalent and a mixed covalent/noncovalent approach (Chem. Comm., 48, 4046-4048, 2012). Now we are working with tris-calixarene in order to increase the complexity of these systems and to get the control on other interesting properties.

My research activity is mainly focused on “Interactions of water-soluble porphyrinoids with biomolecules”. Interaction between porphyrinoids and biomolecules is a very studied topic owing to the clinical use of these macrocycles in the cure of cancer by photodynamic therapy. Among the all biomolecules we decide to study the interaction of porphyrinoids with proteasome and nucleic acids.

Recently inhibition of proteasome (major cytosolic proteolytic system in prokaryotes and eukaryotes, with critical functions in cell cycle control, apoptosis, inflammation, transcription, signal transduction, protein quality control, and many other biological processes) has become a new promising strategy in cancer therapeutics. For this reason I investigated porphyrinoids as inhibitors of proteasome with the central idea that it would be more convenient to use one single molecule having different biological targets but all converging toward the cure of tumors, instead of using a cocktail of active molecules. Encouraged by the promising results obtained using tetra cationic porphyrin 5,10,15,20-tetrakis(4-Nmethylpyridyl) porphine (J. Am. Chem. Soc., 134, 10451−10457, 2012), I got a grant of 800 000 € and continued to investigate more in deeply the inhibition mechanism using other porphyrin derivatives.

Another interesting use of porphyrinoids is as chiroptical reporters of conformations. These molecules are ideal chiroptical reporters because; i) their absorption is far from the region where bases and aminoacids absorbs light and ii) they are not chiral, then even a small induced Circular Dichroism signal is already an useful indication of the DNA structure. Exploiting Circular Dichroism and several other spectroscopic techniques, I characterized the binding modes of tri-cationic corroles on single and double helix of homopolymer nucleic acids (J. Am. Chem. Soc., 135, 8632−8638, 2013). In particular, inspired by the pioneering work of Prof. Purrello (Angew. Chem., Int. Ed., 44, 4006-4009, 2005) demonstrating that the Zn(II) derivative of the tetra cationic 5,10,15,20-tetrakis(4-Nmethylpyridyl) porphine is an excellent (specific and sensitive) sensor for the rare left-handed Z conformation of DNA, we investigated the efficiency of the probe to recognize the Z-structure of short DNA sequence (Biochemical and Biophysical Research Communications 397, 329–332, 2010) and even when it is embedded between two long sequences of B-DNA (Chemistry - An Asian Journal, 6, 3104-3109, 2011). Moreover I demonstrated the central role of the coordinating metal of the porphyrin in the recognition of Z-DNA, in fact using tetra anionic Ni(II) derivative 5,10,15,20-tetrakis(4-sulphonatephenyl) porphine we are able to detect by circular dichroism spectroscopy the Z-DNA conformation and distinguish the non-condensed from the condensed form (Journal of Inorganic Biochemistry 110, 18–20, 2012). By exploiting the supramolecular properties of DNA (such as: spontaneous self-assembly of oligonucleotides with complementary sequences, well-known and characteristic secondary structures) I designed and realized a versatile supramolecular reversible information storing system working as AND logic gates (J. Am. Chem. Soc., 131, 2046-2047, 2009).

Recently we synthetized and characterized a new Zn(II) porphyrin derivative bearing four spermine arms in the meso position (New J. Chem. 39, 6722, 2015), with the aim to design a single molecules able to induce, stabilize and detect the Z-DNA. Even I am exploiting the properties of naked porphyrin derivative bearing four spermine arms, to induce by non-covalent interaction, the formation of superstructures of short aptamers adopting G-quadruplex conformation.
