Quinoxaline-2-carbonitrile.

ABSTRACT: In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012?(1)?Å. Short inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490?(5)?Å] indicate the existence of ??? inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H?N inter-actions, forming R(2) (2) (8) and R(2) (2) (10) ring motifs; these mol-ecules are further linked into a two-dimensional network parallel to (1 0 2) via another C-H?N inter-action.

In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H⋯N inter-actions, forming R(2) (2) (8) and R(2) (2) (10) ring motifs; these mol-ecules are further linked into a two-dimensional net ...[more]

Cholic acid-quinoxaline (2/1).

Project description:In the title inclusion compound, 2C(24)H(40)O(5)·C(8)H(6)N(2), the unit cell contains two mol-ecules of cholic acid (3?,7?,12?-trihydr-oxy-5?-cholan-24-oic acid) and one mol-ecule of quinoxaline which implies disorder of the quinoxaline in the space group P2(1). The amphiphilic mol-ecules of cholic acid assemble, in an anti-parallel arrangement, via O-H?O hydrogen bonds, into typical corrugated host bilayers which are lipophilic on the outside and lipophobic on the inside. The host framework belongs to the so called ?-trans subtype. The quinoxaline mol-ecules are accommodated in lipophilic channels formed between neighboring bilayers with only van der Waals inter-actions between host and guest. There is a crystallographic twofold screw axis directed along an empty channel in the host framework; however, neighboring guests in any one channel are related by a unit-cell translation along the b axis. Thus, the overall structure is a 1:1 superposition of two such channels related by the crystallographic twofold screw axis.

2,3-Dimethyl-6-nitro-quinoxaline.

Project description:The asymmetric unit of the title quinoxaline compound, C(10)H(9)N(3)O(2), contains two crystallographically independent mol-ecules (A and B). The quinoxaline ring systems are essentially planar, with maximum deviations of 0.006 (1) and 0.017 (1) Å, respectively, for mol-ecules A and B. In mol-ecule A, the dihedral angle formed between the quinoxaline ring system and nitro group is 10.94 (3)° [6.31 (13)° for mol-ecule B]. In the crystal, mol-ecules are linked into chains propagating along [001]: one forms zigzag chains linked by C-H⋯O hydrogen bonds, whilst the other forms ladder-like chains by way of C-H⋯N and C-H⋯O hydrogen bonds. The packing is further consolidated by weak π-π inter-actions [range of centroid-centroid distances = 3.5895 (7)-3.6324 (7) Å].

1,3-Diiodo-azulene-2-carbonitrile.

Project description:In the title compound, C11H5I2N, the two iodine-atom substitutents with their large atomic sizes lead to short intra-molecular I⋯H distances (3.01 Å). In the crystal, the tris-ubstituted azulene system forms π-stacks [centroid-centroid distance = 3.6343 (11) Å] along the a-axis direction, showing the characteristic azulene inter-action mode between the electron-rich five-membered ring and the electron-deficient seven-membered ring. I⋯I [3.9129 (2) Å] non-covalent contacts are observed along with weak C-H⋯N and C-H⋯π. bonds.

Activities of Quinoxaline, Nitroquinoxaline, and [1,2,4]Triazolo[4,3-a]quinoxaline Analogs of MMV007204 against Schistosoma mansoni.

Project description:The reliance on one drug, praziquantel, to treat the parasitic disease schistosomiasis in millions of people a year shows the need to further develop a pipeline of new drugs to treat this disease. Recently, an antimalarial quinoxaline derivative (MMV007204) from the Medicines for Malaria Venture (MMV) Malaria Box demonstrated promise against Schistosoma mansoni In this study, 47 synthesized compounds containing quinoxaline moieties were first assayed against the larval stage of this parasite, newly transformed schistosomula (NTS); of these, 16 killed over 70% NTS at 10 µM. Further testing against NTS and adult S. mansoni yielded three compounds with 50% inhibitory concentrations (IC50s) of ≤0.31 µM against adult S. mansoni and selectivity indices of ≥8.9. Administration of these compounds as a single oral dose of 400 mg/kg of body weight to S. mansoni-infected mice yielded only moderate worm burden reduction (WBR) (9.3% to 46.3%). The discrepancy between these compounds' good in vitro activities and their poor in vivo activities indicates that optimization of their pharmacokinetic properties may yield compounds with greater bioavailabilities and better antischistosomiasis activities in vivo.
