Green Synthesis of Fused Imidazo[1,2-a][1,8]naphthyridine Derivatives Catalyzed by DABCO under Solvent-Free Solid-State Conditions and Their Biological Evaluation

An efficient and eco-friendly methodology has been developed for the construction of fused imidazo[1,2-a][1,8]naphthyridine derivatives in the presence of 1,4-diazabicyclo[2.2.2]octane, and involving various substituted heterocyclic amines with phenacyl bromide under solvent-free solid-state condition obtained the corresponding compounds (5a-g, 7a-f) in short reaction time with high yield which is the important features of this protocol. All newly synthesized products were evaluated for their antibacterial and fungal activities. All these compounds displayed good antibacterial and antifungal activity. In predominantly, compounds 7e, 7d, and 5d demonstrate the highest antibacterial and antifungal activities. Furthermore, in silico molecular docking studies results were well complemented to the antimicrobial activity.

Unexpected cascade transformations in the reaction of aromatic aldehydes with the malononitrile dimer

The one-pot reaction of aromatic aldehydes, malononitrile dimer, and triethylamine unexpectedly led to ammonium salts of not previously assumed 5,7-diamino-4-aryl-2-(dicyanomethyl)-1,4-dihydro-1,8-naphthyridine-3,6-dicarbonitriles, but the isomeric 5,7-diamino-4-aryl-2-(dicyanomethyl)-1,4-dihydro-1,6-naphthyridine-3,8-dicarbonitriles.

Anti-Proliferative Properties and Proapoptotic Function of New CB2 Selective Cannabinoid Receptor Agonist in Jurkat Leukemia Cells

Several studies demonstrated that cannabinoids reduce tumor growth, inhibit angiogenesis, and decrease cancer cell migration. As these molecules are well tolerated, it would be interesting to investigate the potential benefit of newly synthesized compounds, binding cannabinoid receptors (CBRs). In this study, we describe the synthesis and biological effect of 2-oxo-1,8-naphthyridine-3-carboxamide derivative LV50, a new compound with high CB2 receptor (CB2R) affinity. We demonstrated that it decreases viability of Jurkat leukemia cells, evaluated by Trypan Blue and 3-(4,5dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), but mainly induces a proapoptotic effect. We observed an increase of a hypodiploid peak by propidium iodide staining and changes in nuclear morphology by Hoechst 33258. These data were confirmed by a significant increase of Annexin V staining, cleavage of the nuclear enzyme poly(ADP-ribose)-polymerase (PARP), and caspases activation. In addition, in order to exclude that LV50 non-specifically triggers death of all normal leukocytes, we tested the new compound on normal peripheral blood lymphocytes, excluding the idea of general cytotoxicity. To characterize the involvement of CB2R in the anti-proliferative and proapoptotic effect of LV50, cells were pretreated with a specific CB2R antagonist and the obtained data showed reverse results. Thus, we suggest a link between inhibition of cell survival and proapoptotic activity of the new compound that elicits this effect as selective CB2R agonist.
