Abstract:
In the course of searching for cholesteryl ester transfer protein (CETP) inhibitors from natural sources, a new type of CETP inhibitor, [10]-dehydrogingerdione (1), was isolated from the extract of rhizomes of Zingiber officinale Roscoe. By NMR spectroscopic analysis of its (1)HNMR, (13)C-NMR, and (1)H-(1)H COSY, HMBC, HMQC and NOESY, more precise structure, compared with its originally proposed structures, of [10]-dehydrogingerdione has been elucidated. This active compound inhibited human plasma CETP with IC(50) values of 35 μM.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Thermal Electrocyclic Reactions: Stereochemistry
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
