Recognition of three xanthine alkaloids caffeine, theobromine and theophylline with acidic fluorescent receptors has been achieved for the first time through the host-guest interaction. The designed receptors are based on the choice of different fluorophores as spacers which can accommodate the bicyclic xanthine guests in between the binding phenolic hydroxyl or carboxyl groups. Among all the xanthine alkaloids, caffeine being the strongest base, its binding constants were maximum though all the nitrogens of caffeine are methylated. Photochemically the trans isomers were converted to the cis isomers which generated cavities for better binding of the xanthine alkaloids. Receptor 4-{4-[4?-(3-Carboxypropoxy)phynylazo]phenoxy}butyric acid (5) has been shown to be most effective in enhancement of fluorescence intensity with caffeine complexation. The binding properties have been studied by a combination of experimental techniques such as UV-visible and fluorescence spectroscopy. Also solid state binding performance between receptor 4,4?-Diazenyldiphenol (4) and caffeine has been described.

In this paper we investigate the possibility of further increase the role of the N-donor aromatic base in antitumor Hollis-type compounds by conferring the possibility to act as a hydrogen-bond donor/acceptor. Therefore, we synthesized the PtII complex cis-[PtCl(NH3) 2(naph)]NO3 (1) containing the 1,8-naphthyridine (naph) ligand. The naphthyridine ligand is generally monodentate, and the second nitrogen atom can act as H-bond donor/acceptor depending upon its protonation state. The possibility of forming such an H-bond could be crucial in the interaction of the drug with DNA or proteins. Apart from the synthesis of the compound, in this study we evaluated its in vitro antitumor activity in a wide panel of tumor cell lines, also including cells selected for their sensitivity/resistance to oxaliplatin, which was compared with that of previously reported complex 2 ([PtI(2,9-dimethyl-1,10-phenanthroline)(1-methyl- cytosine)]I) and oxaliplatin and cisplatin as reference compounds. The cytotoxicity data were correlated with the cellular uptake and the DNA platination levels. Finally, the reactivity of 1 towards guanosine 5?-monophosphate (5′-GMP) and glutathione was investigated to provide insights into its mechanism of action. Monofunctional! The cationic monofunctional PtII complex cis-[PtCl(NH3) 2(naph)]+, containing the H-bond donor/acceptor ligand 1,8-naphthyridine, has been synthesized, characterized, and tested in vitro. The reactivity of the new compound towards GSH and 5?-GMP (as DNA model) was also investigated by multinuclear NMR spectroscopy.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, SDS of cas: 5423-54-1, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 5423-54-1, Name is 1,5-Naphthyridin-4-ol, molecular formula is C8H6N2O

SB-334867 has been an important ligand for the study of the orexin 1 (OX1) receptor due to its high OX1/OX2 selectivity and bioavailability. This ligand however, contains a 2-methylbenzoxazole ring system which is known to undergo hydrolysis, particularly under acidic or basic conditions. The possibility that SB-334867 would be susceptible to significant hydrolysis was evaluated in various formulations and in the solid state. SB-334867 was found to be unstable under conditions commonly employed to prepare stock solutions for in vitro and in vivo studies. In addition, and most alarmingly, the hydrochloride salt of SB-334867 was found to quantitatively decompose to an OX1-inactive product even in the solid state. These findings combine to suggest that studies using SB-334867 (and any other 2-methylbenzoxazole-containing compound) should be performed with great care to avoid the confounding effects of the rapid hydrolytic decomposition of this susceptible structure.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Polyethereal macrocycles were prepared from both 2,6-dichloro-1,5-naphthyridine (2) and 2,7-dichloro-1,8-naphthyridine (6).The “cross-the-face” structures of 1:1 macrocycles 7, derived from 2, were confirmed by NMR.The 2,7-(1,8-naphthyridino) macrocyclic structures 9 and 10 were also supported by NMR data which were indicative of diminished N-electron density, when compared to the parent 1,8-naphthyridine.Template reactions did not appreciably enhance product yields.The X-ray crystal structure of 1:1 macrocycle 9b was conducted and showed that the imidate moieties possess a nearly 0 deg dihedral angle and that the naphthyridine subunit exhibits marginal deviation from planarity.

We consider coordination compounds of ions with unfilled up 3d- and 4f-shell in a weak or intermediary crystalline field, containing dimer clusters in the case when the distance between clusters is more than the distance between the ions forming the cluster. In this case it is possible to neglect the exchange interaction between electrons of different clusters and the structure of the ground state of separate dimer is determined by the intercluster exchange, spin orbital, magnetic dipole?dipole, and hyperfine interactions. The presence of other dimers in the crystal is possible to take into account if populations of energy levels of system upon interacting dimer clusters are calculated.
