Structural basis for the recognition of diastereomeric 5′,8-cyclo-2′-deoxypurine lesions by the human nucleotide excision repair system
TLDR
The locally impaired stacking interaction energies correlate with relative NER incision efficiencies, and explain these results on a structural basis in terms of differences in dynamic perturbations of the DNA backbone imposed by the R and S covalent 5′,8 bonds. Expand
Synthesis and activity of endomorphin-2 and morphiceptin analogues with proline surrogates in position 2.
TLDR
A series of novel EM2 and morphiceptin analogues containing in place of the proline at position 2 the S and R residues of beta-homologues of proline and 2-pyrrolidinemethanesulphonic acid have been synthesized and their binding affinity and functional activity have been investigated. Expand
Affinity of the anthracycline antitumor drugs Doxorubicin and Sabarubicin for human telomeric G-quadruplex structures.
TLDR
It is proved that Doxorubsicin and Sabarubicin bind to the human telomeric sequence, 5'-d[GGG(TTAGGG)(3)]-3' (21-mer), assuming a G-quadruplex structure in the presence of K(+). Expand
A 5′, 8-cyclo-2′-deoxypurine lesion induces trinucleotide repeat deletion via a unique lesion bypass by DNA polymerase β
TLDR
This study indicates that accumulation of cdPus in the human genome can lead to TNR instability via a unique lesion bypass by pol β. Expand
[Cu(TPMA)(Phen)](ClO4)2: Metallodrug Nanocontainer Delivery and Membrane Lipidomics of a Neuroblastoma Cell Line Coupled with a Liposome Biomimetic Model Focusing on Fatty Acid Reactivity
TLDR
Preliminary but important elements of copper(II) complex reactivity in cellular and biomimetic models are given, pointing mainly to the effects on membrane reactivity and remodeling based on the balance between SFA and MUFA in cell membranes that are subjects of strong interest for chemotherapeutic activities as well as connected to nutritional strategies. Expand
A problem solving approach for the diastereoselective synthesis of (5′S)- and (5′R)-5′,8-cyclopurine lesions
A short, efficient and high-yielding approach for the diastereoselective syntheses of the four (5′S)- and (5′R)-5′,8-cyclopurine lesions and their phosphoramidites has been developed. TheExpand
On the relevance of hydroxyl radical to purine DNA damage.
TLDR
This review focuses on the purine DNA damage by HO• radicals, and emphasis is given on mechanistic aspects for the various lesion formation and their interconnections. Expand
Complexes of the antitumoral drugs Doxorubicin and Sabarubicin with telomeric G-quadruplex in basket conformation: ground and excited state properties.
We studied the binding of two anthracycline drugs, Doxorubicin and Sabarubicin, to a model telomeric sequence 5'-d[GGG(TTAGGG)(3)]-3' (21-mer), assuming the basket G-quadruplex (G4) conformation inExpand
A cationic Zn(II) porphyrazine induces a stable parallel G-quadruplex conformation in human telomeric DNA.
A water soluble Zn(II) porphyrazine drives the conformational equilibrium of the G-quadruplex of a human telomeric sequence exclusively towards a parallel conformation upon complexation.
