Synthesis of a novel PEGylated colon-specific azo-based 4- aminosalicylic acid prodrug

Objective(s): 4-aminosalicylic acid (4-ASA) is an isomer of mesalazine that has recently been shown to be effective against inflammatory bowel disease (IBD), and more specifically, ulcerative colitis. However, the majority of orally administered 4-ASA is readily and extensively absorbed from the stomach and small intestine, so only a small amount is transported to the ...

4-Amino­pyridinium 4-nitro­benzoate 4-nitro­benzoic acid

The asymmetric unit of the title compound, C(5)H(7)N(2) (+)·C(7)H(4)NO(4) (-)·C(7)H(5)NO(4), consists of an amino-pyridinium cation, a 4-nitro-benzoate anion and a neutral 4-nitro-benzoic acid mol-ecule. The pyridine ring forms dihedral angles of 64.70 (5)° and 70.37 (5)°, respectively, with the benzene rings of 4-nitro-benzoic acid and 4-nitro-benzoate. In the crystal structure, the cations, a...

4-(4-Meth­oxy­benzene­sulfonamido)­benzoic acid

The asymmetric unit of the title compound, C(14)H(13)NO(5)S, contains two independent mol-ecules in which the dihedral angles between the aromatic rings are 83.45 (11) and 86.65 (9)°. In the crystal, the independent mol-ecules are connected by N-H⋯O and O-H⋯O hydrogen bonds, forming a double-chain structure along [401]. A weak π-π stacking inter-action with a centroid-centroid distance of 3.750...

4-(4-Propoxybenzo­yloxy)benzoic acid

The title compound, C(17)H(16)O(5), is an important inter-mediate for the synthesis of side-chain ligands for polymeric liquid crystals. The prop-oxy and benzoic acid groups subtend dihedral angles of 4.36 (6) and 55.35 (6)°, respectively, with the central benzo-yloxy unit. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond.
