چکیده
The air-stable title compound, C(12)H(13)N(3)O, which is of inter-est due to its anti-bacterial properties, is an almost planar mol-ecule in which the ten atoms forming the 1,8-naphthyridine ring have an r.m.s. deviation of 0.03 Å from the least-squares plane calculated using the ten atoms. The plane of the acetyl-amino group is slightly inclined [11.7 (2)°] to the plane of the 1,8-naphthyridine ring.

The title compound, C(26)H(22)N(4)O(2)·2CH(3)OH, was synthesized and characterized by (1)H NMR spectroscopy and X-ray structure analysis. There is one half-mol-ecule in the asymmetric unit with a centre of symmetry located at the centre of the benzene ring. The two bridged naphthyridine ring systems are in an anti-parallel orientation. In the crystal structure, O-H⋯N, C-H⋯O and C-H⋯N inter-acti...
متن کاملEffect of substituents of alloxazine derivatives on the selectivity and affinity for adenine in AP-site-containing DNA duplexes.
Using the DNA duplex containing an AP site (5'-TCC AGX GCA AC-3'/3'-AGG TCN CGT TG-5', X = AP site, N = A, T, C, or G), we have found that 2-amino-4-hydroxypteridine (pterin) selectively binds to guanine (G), and that the enhanced binding affinity for G is obtained by its methylated derivative 2-amino-6,7-dimethyl-4-hydroxypteridine (diMe pteridine). Similarly, among the cytosine (C)-selective ...

In the title compound, [Cd(NO(3))(2)(C(10)H(11)N(3))(2)], two naph-thyridine ring systems are coordinated to the Cd ion through the two N atoms in a bidentate chelating mode, whereas the remaining coordination sites are occupied by two O atoms from two different nitrate groups to complete the octahedral geometry. Inter-moleular N-H⋯O hydrogen bonds link the mol-ecules to form a one-dimensionnal...

The title compound, [CoCl(2)(C(10)H(11)N(3))(2)]·2CH(3)OH, crystallizes with an elongated Co coordination polyhedron in a very distorted octa-hedral geometry. Both naphthyridine ligands coordinate to the Co atom via two N atoms in a bidentate chelating mode. The remaining coordination sites are occupied by two Cl atoms. Two uncoordinated solvent methanol mol-ecules are hydrogen bonded to the Cl...
متن کاملInfluence of substituent modifications on the binding of 2-amino-1,8-naphthyridines to cytosine opposite an AP site in DNA duplexes: thermodynamic characterization
Here, we report on a significant effect of substitutions on the binding affinity of a series of 2-amino-1,8-naphthyridines, i.e., 2-amino-1,8-naphthyridine (AND), 2-amino-7-methyl-1,8-naphthyridine (AMND), 2-amino-5,7-dimethyl-1,8-naphthyridine (ADMND) and 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND), all of which can bind to cytosine opposite an AP site in DNA duplexes.
