Abstract
A new norcembranoidal diterpene, 1-epi-sinulanorcembranolide A (1), and a new cembranoidal diterpene, flexibilin D (2), were isolated from the soft corals, Sinularia gaweli and Sinularia flexibilis, respectively. The structures of new metabolites 1 and 2 were elucidated by spectroscopic methods, and compound 2 was found to significantly inhibit the accumulation of the pro-inflammatory iNOS and COX-2 proteins of the lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. In addition, S. flexibilis yielded a known cembrane, 5-dehydrosinulariolide (3); the structure, including its absolute stereochemistry, was further confirmed by single-crystal X-ray diffraction analysis.

Abstract
Chemical investigations of the Formosan soft coral Cespitularia hypotentaculata ROXAS led to the isolation of two new verticillane diterpenoids, cespitularins R and S (1, 2), along with seven known compounds (3-9). The structures of these isolated compounds were elucidated on the basis of extensive spectroscopic analysis and by comparison with those of reported in literature. The anti-inflammatory activity using RAW 264.7 macrophages of compounds 1-9 were evaluated in vitro.

Abstract
The solid-state structure of the first reported homoleptic copper di-2-pyridylphosphinate complex shows an extremely large 'z-out' tetragonal distortion, with an axial Cu.O distance of 2.430 (2) A. The title complex, [Cu(C(10)H(8)N(2)O(2)P)(2)].2CH(2)Cl(2) or Cu[py(2)P(O)O](2).2CH(2)Cl(2), comprises two di-2-pyridylphosphinate ligands coordinated to the central copper(II) ion, which sits on an inversion center. The pyridyl rings of one ligand are trans to the pyridyl rings of their symmetry-related counterpart. The two trans py-Cu-py moieties are coplanar, as required by the inversion symmetry. A disordered dichloromethane solvent molecule is cocrystallized in the asymmetric unit cell.
