4-Aminobenzoic acid–quinoline (1/1)

Mechanism of inactivation of myeloperoxidase by 4-aminobenzoic acid hydrazide.

Hypochlorous acid is the most powerful oxidant generated by neutrophils and is likely to contribute to the damage mediated by these inflammatory cells. The haem enzyme myeloperoxidase catalyses its production from hydrogen peroxide and chloride. 4-Aminobenzoic acid hydrazide (ABAH) is a potent inhibitor of hypochlorous acid production. In this investigation we show that, in the presence of hydr...

Crystal Growth, Optical and Thermal Studies of 4-Nitroaniline 4- Aminobenzoic Acid: A Fluorescent Material

The organic single crystals of 4-nitroaniline 4aminobenzoic acid (4NAABA) were grown from ethanol solvent. The grown crystals have been confirmed from single crystal XRD analysis. The UV absorption was carried out which shows the cutoff wavelength around 459 nm. The optical band gap of the crystal has been evaluated from the absorption spectra and absorption coefficient by extrapolation techniq...

4,4′-Bipyridinium bis(perchlorate)–4-aminobenzoic acid–4,4′-bipyridine–water (1/4/2/2)

In the structure of the title compound, C(10)H(10)N(2) (2+)·2ClO(4) (-)·4C(7)H(7)NO(2)·2C(10)H(8)N(2)·2H(2)O, the 4,4'-bipyridinium cation has a crystallographically imposed centre of symmetry. The cation is linked by N-H⋯N hydrogen bonds to adjacent 4,4'-bipyridine mol-ecules, which in turn inter-act via O-H⋯N hydrogen bonds with 4-amino-benzoic acid mol-ecules, forming chains running parallel...
