Potential Antitumor Effect of Newly Synthesized Dinuclear1,5-Naphthyridine-Bridging Palladium(II) Complexes

Five new dinuclear palladium(II) complexes with general formula, [{Pt(L)Cl}(2)(mu-1,5-nphe)](NO3)(2)(L is ethylenediamine (en), (+/-)-1,2-propylenediamine (1,2-pn),trans-(+/-)-1,2-diaminocyclohexane (dach), 1,3-propylenediamine (1,3-pd), (+/-)-1,3-pentanediamine (1,3-pnd) and 1,5-nphe is bridging 1,5-naphthyridine ligand) were synthesised and spectroscopically characterized.In vitrocytotoxic activity of these complexes was evaluated against mouse mammary carcinoma (4T1), colon (CT26), lung cancer cells (LLC1) and melanoma (B16-F10) as well as human lung adenocarcinoma (A549), mammary carcinoma (MDA-MB-468), and colon cancer (HCT 116). The investigated complexes reduced viability of tumor cells in dose dependent manner. Dinuclear Pd(II) complexes act less cytotoxic toward tumor cells, compare to cisplatin, but also have greater selectivity toward mesenchymal stem cells. The potential mechanism of cell death of tumor cells treated with palladium(II) 1,5-naphthyridine dinuclear complexes is enhanced apoptosis, facilitated by down-regulation of anti-apoptotic Bcl-2 and up-regulation of pro-apoptotic Caspase-3.

Influence of Aaptamine Alkaloids on the Growth of Seedling Roots of Agricultural Plants

The effect of spongean alkaloids aaptamine (1), isoaaptamine (2), 9-demethylaaptamine (3), aaptanone (4), N-demethylaaptanone (5), and semisynthetic 4-N-methylaaptanone (6) was studied on the growth of seedlings roots of soy {Glycine max (L.) Merr.}, maize (Zea mays L.), wheat (Triticum aestivum L.), buckwheat (Fagopyrum esculentum Moench), and barley (Hordeum vulgare L.). It was shown that a stimulatory effect depends on the chemical structure of the compounds and species of crop plants. The structural motif of aaptamines 1-3 is essential for a stimulating activity on the growth of seedling roots of soy, maize, and wheat. The oxygenated 1,6-naphthyridine core of aaptanones 5 and 6 is important for their growth stimulating activity on barley roots.

Synthesis, Inhibitory Activity of Cholinesterases, and Neuroprotective Profile of Novel 1,8-Naphthyridine Derivatives

1,8-Naphthyridine derivatives related to 17 (ITH4012), a neuroprotective compound reported by our research group, have been synthesized. In general, they have shown better inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) than most tacrine derivatives previously synthesized in our laboratory. The compounds presented an interesting neuroprotective profile in SH-SY5Y neuroblastoma cells stressed with rotenone/oligomycin A. Moreover, compound 14 (ethyl 5-amino-2-methy1-6,7,8,9-tetrahydrobenzo[b][1,8]naphthyridine-3-carboxylate) also caused protection in cells stressed with okadaic acid (OA) or amyloid beta 1-42 peptide (A beta(1-42)). Interestingly, compound 14 prevented the OA-induced PP2A inhibition, one of the enzymes implicated in tau dephosphorylation. This compound also exhibited neuroprotection against neurotoxicity elicited by oxygen and glucose deprivation in hippocampal slices. Because these stressors caused neuronal damage related to physiopathological hallmarks found in the brain of Alzheimer’s disease (AD) patients, we conclude that compound 14 deserves further in vivo studies in AD models to test its therapeutic potential in this disease.

Face-to-face porphyrin moieties assembled with spacing for pyrazine recognition in molecularly imprinted polymers

A strategy for arranging two porphyrin moieties in a face-to-face fashion in polymeric material was demonstrated by molecular imprinting, whereby porphyrin Zn(II) complex monomers were cross-linked with ethylene glycol dimethacrylate in the presence of pyrazine or 1,5-naphthyridine as a template molecule. In chromatographic studies using the resultant imprinted polymers as stationary phase, both the polymers showed selectivity for the original template molecule, suggesting that two zinc porphyrin moieties were immobilized in the face-to-face fashion, and were center-aligned for pyrazine recognition and offset-arranged for 1,5-naphthyridine recognition. The imprinted polymer with porphyrin moieties also showed a decrease in its fluorescence intensity in response to the concentration of the target molecule, suggesting the potential utility as sensing material.
