2-Carbamoyl-3,4,5,6-tetrafluorobenzoic acid
In the title compound, C(8)H(3)F(4)NO(3), the carb-oxy group lies nearly in the plane of the ring with a C-C-C-O torsion angle of -10.5 (4)°. The carbamoyl group is almost perpendic-ular to the benzene ring [C-C-C-O torsion angle = 82.2 (4) °]. In the crystal, molecules are linked via O-H⋯O and N-H⋯O hydrogen bonds involving the carbamoyl and carb-oxy groups.

In the title compound, C(11)H(14)N(2)O(6)S, an amino acid-derived sulfonamide, the acetamido group and the carb-oxy-lic group are oriented at dihedral angles of 45.84 (5)° and 47.97 (5)° respectively, with respect to the aromatic ring. In the crystal, the mol-ecules are connected by N-H⋯O and O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, forming a three-dimensional network.

Heparan sulfate proteoglycans (HSPGs) have long been implicated in a wide range of cell-cell signaling and cell-matrix interactions, both in vitro and in vivo in invertebratemodels. Althoughmanyof the genes that encode HSPG core proteins and the biosynthetic enzymes that generate and modify HSPG sugar chains have not yet been analyzed by genetics in vertebrates, recent studies have shown that H...

In the title compound, C(10)H(15)NO(5), the five-membered cyclo-pentane ring has an envelope conformation, with four atoms lying in a plane (mean deviation = 0.0213 Å), while the fifth atom deviates from this plane by 0.626 (2) Å. A three-dimensional structure is formed through N-H⋯O and O-H⋯O hydrogen bonds between the amide and carb-oxy-lic acid groups and both carb-oxy-lic acid and amide O-a...
