4-(Cyclo-propane-carboxamido)-benzoic acid.

In the title compound, C(11)H(11)NO(3), the dihedral angle between the benzene ring and the cyclo-propane ring is 63.2 (1)°. In the crystal, mol-ecules are linked through classical cyclic carb-oxy-lic acid O-H⋯O hydrogen-bond inter-actions [graph set R(2) (2)(8)] giving centrosymmetric dimers which are extended along the b-axis direction through amide N-H⋯O hydrogen-bond inter-actions, giving one-dimensional ribbon structures. Weak C-H⋯O inter-actions are also present in the structure.

Cytotoxic alkoxylated xanthones from the resin of Garcinia hanburyi.

Three new xanthones, garcinolic acid (1), 10α-ethoxy-9,10-dihydromorellic acid (2), and 10α-ethoxy-9,10-dihydrogambogenic acid (3), along with six known compounds were isolated from the resin of Garcinia hanburyi. These compounds were tested for their cytotoxicities against A549, HCT116, SK-BR-3 and HepG2, and showed high inhibitory effects on the cell lines.
