3α-Hydroxy-ent-atis-16-en-14-one
The title compound, C(20)H(30)O(2), is an ent-atisane diterpenoid which was isolated from the roots of Euphorbia kansuensis. The mol-ecule contains five six-membered rings, among which three six-membered rings of the bicyclo-[2.2.2]octane unit adopt boat conformations and two cyclo-hexane rings adopt chair conformations. In the crystal structure, mol-ecules are connected by inter-molecular O-H⋯...

The title compound, C(26)H(34)O(9), a natural ent-kaurane diterpenoid, is composed of four rings with the expected cis and trans junctions. In the crystal structure, the mol-ecules stack along the a axis and are linked together by inter-molecular O-H⋯O hydrogen bonds.
متن کاملInduction of laryngeal cancer cell death by Ent-11-hydroxy-15-oxo-kaur-16-en-19-oic acid.
BACKGROUND Ent-11-hydroxy-15-oxo-kaur-16-en-19-oic acid (5F) is known to exhibit antitumor activity, but its mechanism is not completely understood. 5F has not been tested in laryngeal cancer. METHODS Two laryngeal cancer cell lines were treated with 5F. Cell death was analyzed by MTT [3-(4,5-dimethylthiozol-2-yl)-2,5-diphenyltetrazolium bromide] and Annexin V assay. Nuclear factor kappa beta...
متن کاملPositive Relationship between Menstrual Synchrony and Ability to Smell 5α-Androst-16-en-3α-ol
To explore the possibility that compounds which were identified as pheromones in experimental animals mediate human menstrual synchrony, we examined the relationship between menstrual synchrony and the ability to smell putative pheromones, 5α-androst-16-en-3α-ol (3α-androstenol) and 5α-androst-16-en-3-one (5α-androstenone). When we examined menstrual synchrony among 64 women living together in ...
متن کامل(22E,24R)-3α,5-Cyclo-5α-ergosta-22-en-6-one
In the title mol-ecule, C(28)H(44)O, the two six-membered rings have a chair conformation and the two five-membered rings haveenvelope conformations. The crystal packing exhibits no short inter-molecular contacts. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of the title compound.
