N-(Pyrazin-2-yl)-1,8-naphthyridin-2-amine.

ABSTRACT: There are two independent mol-ecules in the asymmetric unit of the title compound, C12H9N5, in which the C-N(amine)-C angles differ slightly [129.63?(11) and 132.02?(11)°]. In each independent mol-ecule, an intra-molecular C-H?N hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The independent mol-ecules are linked via an N-H?N hydrogen bond. Further N-H?N and C-H?N hydrogen bonds connect the mol-ecules into chains along c axis. Pairs of C-H?? inter-actions between the chains lead to sheets parallel to the b axis. These are linked by ?-? inter-actions between the naphthyridine and pyrazine rings [centroid-centroid separations of 3.553?(8)?Å] into a three-dimensional supra-molecular network.

There are two independent mol-ecules in the asymmetric unit of the title compound, C12H9N5, in which the C-N(amine)-C angles differ slightly [129.63 (11) and 132.02 (11)°]. In each independent mol-ecule, an intra-molecular C-H⋯N hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The independent mol-ecules are linked via an N-H⋯N hydrogen bond. Further N-H⋯N and C-H⋯N hydrogen bonds connect the mol-ecules into chains along c axis. Pairs of C-H⋯π inter-actions between t ...[more]

Crystal structures of the dioxane hemisolvates of <i>N</i>-(7-bromo-methyl-1,8-naphthyridin-2-yl)acetamide and bis-[<i>N</i>-(7-di-bromo-methyl-1,8-naphthyridin-2-yl)acetamide].

Project description:The syntheses and crystal structures of N-(7-bromo-methyl-1,8-naphthyridin-2-yl)acetamide dioxane hemisolvate, C11H10BrN3O·0.5C4H8O2, (I), and bis-[N-(7-di-bromo-methyl-1,8-naphthyridin-2-yl)acetamide] dioxane hemisolvate, 2C11H9Br2N3O·0.5C4H8O2, (II), are described. The mol-ecules adopt a conformation with the N-H hydrogen pointing towards the lone electron pair of the adjacent naphthyridine N atom. The crystals of (I) are stabilized by a three-dimensional supra-molecular network comprising N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds, as well as C-Br⋯π halogen bonds. The crystals of compound (II) are stabilized by a three-dimensional supra-molecular network comprising N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds, as well as C-H⋯π contacts and C-Br⋯π halogen bonds. The structure of the substituent attached in the 7-position of the naphthyridine skeleton has a fundamental influence on the pattern of inter-molecular noncovalent bonding. While the Br atom of (I) participates in weak C-Br⋯Oguest and C-Br⋯π contacts, the Br atoms of compound (II) are involved in host-host inter-actions via C-Br⋯O=C, C-Br⋯N and C-Br⋯π bonding.

Microwave-Assisted Synthesis of Novel Pyrazolo[3,4-g][1,8]naphthyridin-5-amine with Potential Antifungal and Antitumor Activity.

Project description:The microwave assisted reaction between heterocyclic o-aminonitriles 1 and cyclic ketones 2 catalyzed by zinc chloride led to new series of pyrazolo[3,4-b] [1,8]naphthyridin-5-amines 3 in good yields. This procedure provides several advantages such as being environmentally friendly, high yields, simple work-up procedure, broad scope of applicability and the protocol provides an alternative for the synthesis of pyrazolonaphthyridines. The whole series showed antifungal activities against Candida albicans and Cryptococcus neoformans standardized strains, being compounds with a 4-p-tolyl substituent of the naphthyridin scheleton (3a, 3d and 3g), the most active ones mainly against C. albicans, which appear to be related to their comparative hydrophobicity. Among them, 3d, containing a cyclohexyl fused ring, showed the best activity. The anti-Candida activity was corroborated by testing the three most active compounds against clinical isolates of albicans and non-albicans Candida strains. These compounds were also screened by the US National Cancer Institute (NCI) for their ability to inhibit 60 different human tumor cell lines. Compounds 3a and 3e showed remarkable antitumor activity against cancer cell lines, with the most important GI50 values ranging from 0.62 to 2.18 ?M.

[?-Bis(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene]bis-[difluoridoboron(III)].

Project description:In the title compound, C(20)H(18)B(2)F(4)N(6), the bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene molecule is bis-ected by a symmetry centre midway between the central N atoms of the diazene group. Each of the symmetry-related halves of the molecule binds to a B atom through an N,N'-bite. Two terminal F ions complete the distorted BN(2)F(2) tetra-hedral geometry around each B atom. The BF(2) plane is almost perpendicular to the boron-naphthyridine ring plane, with a dihedral angle of 87.8?(2)°. The main inter-actions in the crystal structure are some C-H?F hydrogen bonds and ?-? contacts between 1,8-naphthyridine rings [centroid-centroid distance = 4.005?(1)?Å].

7-Amino-1,8-naphthyridin-2(1H)-one monohydrate.

Project description:In the crystal structure of the title compound, C(8)H(7)N(3)O·H(2)O, adjacent organic mol-ecules are linked together into a tape along the a axis through N-H?N and N-H?O hydrogen bonds. On the other hand, water mol-ecules are linked together to form a chain along the b axis through O-H?O hydrogen bonds. The water chains and the organic mol-ecular tapes are further connected by inter-molecular O-H?O hydrogen bonds, forming a three-dimensional network. In addition, a ?-? stacking inter-action between the 1,8-naphthyridine ring systems with an inter-planar separation of 3.246?(1)?Å and a centroid-centroid distance of 3.825?(2)?Å is observed.

N-(7-Dibromo-methyl-5-methyl-1,8-naphthyridin-2-yl)acetamide-pyrrolidine-2,5-dione (1/1).

Project description:In the title co-crystal, C(12)H(11)Br(2)N(3)O·C(4)H(5)NO(2), the naphthyridine derivative and the pyrrolidine-2,5-dione mol-ecules have crystallographic mirror-plane symmetry with all non-H atoms, except the Br atom, located on the mirror plane. In the crystal, N-H?N, N-H?O and C-H?O hydrogen bonds link the mol-ecules into heterodimers. These dimers are further linked into a one-dimensional structure along [010] by weak C-Br?O inter-actions [Br?O = 3.028?(5)?Å and C-Br?O = 158.52?(4)°].

2,6-Diamino-pyridinium tetra-phenyl-borate-1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene (1/1).

Project description:In the title compound, C(5)H(8)N(3) (+)·C(24)H(20)B(-)·C(20)H(18)N(6), the 1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene mol-ecule is essentially planar (r.m.s. deviation = 0.0045?Å) and aligned in nearly coplanar manner with the 2,6-diamino-pyridinium ion, making a dihedral angle of 5.19?(5)°. The diamino-pyridine mol-ecule is protonated on the central pyridine N atom and the B atom bears the counter-charge. The amine groups of the diamino pyridinium cation form intra-molecular N-H?N hydrogen bonds, resulting in linear and bent inter-actions with the naphthyridine ring system.

Synthesis and biological evaluation of 3-(1,3,4-oxadiazol-2-yl)-1,8-naphthyridin-4(1H)-ones as cisplatin sensitizers.

Project description:A series of novel 3-(1,3,4-oxadiazol-2-yl)-1,8-naphthyridin-4(1H)-one derivatives were synthesized and their anti-cancer as well as cisplatin sensitization activities were evaluated. Among them, compounds 6e and 6h exhibited significant cisplatin sensitization activity against HCT116. Hoechst staining and annexin V-FITC/PI dual-labeling studies demonstrated that the combination of 6e/6h and cisplatin can induce tumour cell apoptosis. Western blot showed that the expression of ATR downstream protein, CHK1, decreased in 6e + cisplatin and 6h + cisplatin groups compared with that in the test compound and cisplatin group. Furthermore, docking of 6e/6h into the ATR structure active site revealed that the N1 and N8 atoms in the naphthyridine ring and the hybrid atom in the oxadiazole ring are involved in hydrogen bonding with Val170, Glu168 and Tyr155. Additionally, the naphthyridine ring is also involved in ?-? stacking with Trp169. Accordingly, compounds 6e and 6h can be expected to be potential cisplatin sensitizers that can participate in HCT116 cancer therapy.
