3-Hexyl-4,5-dithiacycloheptanone

The structures of nine of these compounds were determined by spectroscopic methods, while those of the 14 remaining materials were established by GC-MS only. The compounds can be classified into four types (A to D) the 1,2,4-trithiolanes (145-154), 1,2,4,5-tetrathianes (155-157), 1,2,3,5,6-pentathiepanes (158-163), which are all generally quite stable compounds, and the monoalkyl-substituted polysulfides (164-167), which tend to disproportionate into sulfur and disubstituted cyclic polysulfides. These compounds are structurally related to the cyclic polysulfide compounds reported from red alga Chondria californica in 1976 [136] and to compound 168 (3-hexyl-4,5-dithiacycloheptanone) reported from the brown algae of the Dictyopteris genus in 1971 [137]. The latter compound has more recently been found to be a potent inhibitor of bee venom-derived phospholipase A2 (PLA2) [138].
