Radiotracers suitable for positron emission tomography studies often serve as preclinical tools for in vivo receptor occupancy. The serotonin 1B receptor (5-HT(1B)) subtype is a pharmacological target used to discover treatments for various psychiatric and neurological disorders. In psychiatry, 5-HT(1B) antagonists may provide novel therapeutics for depression and anxiety. We report on the in v...
In the title compound, C(16)H(11)FN(2)O(4)S, the mean planes of the bicyclic chromone system and of the benzene ring of the benzothia-diazine derivative make a dihedral angle of 54.28 (5)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked into layers by N-H⋯O and C-H⋯O hydrogen bonds, generating an infinite two-dimensional network.
In the title hydrate, C19H16N2O4·H2O, the 4H-chromen-4-one segment is slightly twisted, with a dihedral angle between the two six-membered rings of 3.30 (5)°. The dihedral angles between the plane of the pyran-one ring and the hydrazide plane and between the planes of the pyran-one ring and the benzene ring of the p-meth-oxy-benzene unit are 26.69 (4) and 2.23 (3)°, respectively. The mol-ecule ...
