The title compound, C(10)H(11)NO(4)S, is of inter-est with respect to its biological activity. The mol-ecules are linked into centrosymmetric dimers by inter-molecular O-H⋯O hydrogen bonds and the dimers are further connected into chains by weak C-H⋯O inter-actions.

Abstract Nonsteroidal anti-inflammatory drugs (NSAIDs) and coxibs are traditional medicines for the treatment of inflammation, yet associated with serious side effects. Hence, need discovering novel compounds valuable clinical benefits is great importance. In this study, 18 derivatives p-nitrophenyl hydrazones were docked against COX-2, 5-LOX, H+/K+ ATPase, followed by predicting their drug-lik...

Tumor hypoxia is associated with the rapid proliferation and growth of malignant tumors, and the ability to detect tumor hypoxia is important for predicting tumor response to anti-cancer treatments. We have developed a class of dye-conjugates that are related to indocyanine green (ICG, ) to target tumor hypoxia, based on in vivo infrared fluorescence imaging using nitroimidazole moieties linked...

In the title compound, C(12)H(16)N(2)O(6)S, the S atom adopts a distorted tetra-hedral geometry with an O-S-O angle of 119.76 (13)°. The nitro group is twisted by 35.34 (2)° with respect to the aromatic ring; it accepts an N-H⋯O hydrogen bond, resulting in a S(7) motif. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the mol-ecules into an infinite chain along the a axis. The methyl C at...

In the crystal structure of the title compound, C(16)H(15)NO(3), inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the b axis and pairs of inter-molecular O-H⋯O hydrogen bonds between inversion-related carb-oxy-lic acid groups link the mol-ecules into dimers. The dihedral angle between the two benzene rings is 82.4 (2)°.
