Among the exogenous NO donors, ruthenium nitrosyl/nitro complexes are potential candidates for prodrugs, due to their physicochemical properties, such as thermal and physiological pH stability. In this work, we proposed the synthesis and physical characterization of the new nitro terpyridine ruthenium (II) complexes of the type [Ru^II(L)(NO₂)(tpy)]PF₆ where tpy = 2,2':6′,2″-terpyridine; L = 3,4-diaminobenzoic acid (bdq) or <em>o</em>-phenylenediamine (bd) and evaluation of influence of diimine bidentate ligand NH.NHq-R (R = H or COOH) in the HSA/DNA interaction as well as antiviral activity. The interactions between HSA and new nitro complexes [Ru^II(L)(NO₂)(tpy)]⁺ were evaluated. The <em>K</em>_a values for the HSA–[Ru^II(bdq)(NO₂)(tpy)]⁺ is 10 times bigger than HSA–[Ru^II(bd)(NO₂)(tpy)]⁺. The sites of interaction between HSA and the complexes via synchronous fluorescence suppression indicate that the [Ru^II(bdq)(NO₂)(tpy)]⁺ is found close to the Trp-241 residue, while the [Ru^II(bd)(NO₂)(tpy)]⁺ complex is close to Tyr residues. The interaction with fish sperm <em>fs</em>-DNA using direct spectrophotometric titration (K_b) and ethidium bromide replacement (K_SV and K_app) showed weak interaction in the system <em>fs</em>-DNA-[Ru^II(bdq)(NO)(tpy)]⁺. Furthermore, <em>fs</em>-DNA–[Ru^II(bd)(NO₂)(tpy)]⁺ and <em>fs</em>-DNA–[Ru^II(bd)(NO)(tpy)]³⁺ system showed higher intercalation constant. Circular dichroism spectra for <em>fs</em>-DNA–[Ru^II(bd)(NO₂)(tpy)]⁺ and <em>fs</em>-DNA–[Ru^II(bd)(NO)(tpy)]³⁺, suggest semi-intercalative accompanied by major groove binding interaction modes.

In the present study, we report the development of chitosan cryogels (CS) with a porous structure of interconnected cells, with wall thicknesses in the range of 340–881 nm, capable of releasing NO triggered by the rapid hydration process. This property was obtained using an innovative strategy based on the functionalization of CS with two previously synthesized S-nitrosothiols: S-nitrosothioglycolic acid (TGA(SNO)) and S-nitrosomercaptosuccinic acid (MSA(SNO)). For this purpose, CS was previously methacrylated with glycidyl methacrylate and subsequently submitted to photocrosslinking and freeze-drying processes. The photocrosslinked hydrogels thus obtained were then functionalized with TGA(SNO) and MSA(SNO) in reactions mediated by carbodiimide. After functionalization, the hydrogels were frozen and freeze-dried to obtain porous S-nitrosated chitosan cryogels with high swelling capacities.
