We have identified through bioassay guided isolation an allelochemical, eudesmane-type sesquiterpeniod, 3β-caffeoxyl-β1,8α-dihydroxyeudesm-4(15)-ene(1),from an endemic plant species growing in the Himalayas. In our search for the bioactive subfraction, the hexane one was highly significant, ...

Aerobic and anaerobic respiratory systemsallow cells to transport the electrons to terminal electron acceptors. The quinone (ubiquinone or menaquinone) pool is central to the electron transport chain. In the majority of Gram-positive bacteria, vitamin K2 (menaquinone) is the sole quinone in the ...
09-Mar-2010 | Flores-Larios, Irma Y. ; López-Garrido, Lizbeth ; Martínez-Martínez, Francisco J. ; González, Jorge ; García-Báez, E ..., Molecules, 2010
The thermal [4+2] cycloadditions of 3-acetyl-, 3-carbamoyl, and 3-ethoxycarbonylcoumarins with 2,3-dimethyl-1,3-butadiene under solvent free conditions are reported, as well as the epoxidation reactions of some adducts. Discussion is focused on the structural features of the Diels-Alder adducts ...
09-Mar-2010 | Flores, Mari Fe. ; Núñez, Marta G. ; Moro, Rosalina F. ; Garrido, Narciso M. ; Marcos, Isidro S. ; Iglesias, Enrique ..., Molecules, 2010
The synthesis of a new chiral pyrrolidine has been performed using 2,3-O-isopropylidene-D-erythronolactol as a suitable starting material.
09-Mar-2010 | Obora, Yasushi ; Ishii, Yasutaka, Molecules, 2010
The direct aerobic coupling reaction of arenes with olefins was successfully achieved by the use of Pd(OAc)2/molybdovanadophosphoric acid (HPMoV) as a key catalyst under 1 atm of dioxygen. This catalytic system could be extended to the coupling reaction of various substituted benzenes with ...

Coprinus comatus, also called chicken drumstick mushroom, is currently commercially available in China. Hot water and ethanolic extracts were prepared from cap and stipe of C. comatus fruit bodies and their antioxidant properties were studied. Ethanolic extract from stipe showed high antioxidant ...

The oxidation of 1-unsubstituted or 1-phenyl-1H-isotellurochromenes with m-chloroperbenzoic acid (mCPBA) in CHCl3 resulted in a ring opening reaction to produce as the sole products the corresponding o-formyl or benzoyl distyryl ditellurides, which were also produced by the hydrolysis of the ...
