Intramolecular cyclopropene-furan [2 + 4] cycloaddition followed by a cyclopropylcarbinyl rearrangement to synthesize the BCD rings of cortistatin A.

Sep 2009 Synthesis of the BCD ring system of cortistatin A has been accomplished in 9 steps and 30% overall yield starting from commercially available 2-methylcyclopent-2-enone. Key transformations include the addition of cyclopropenyllithium 16 to aldehyde ... Read more...

Activation of a novel estrogen receptor, GPER, is cardioprotective in male and female rats.

26 Aug 2009 Premenopausal females have a lower incidence of cardiovascular disease than their male counterparts, but the mechanism is unclear. Estrogen has been thought to signal through two nuclear receptors: estrogen receptor-alpha or estrogen receptor-beta; ... Read more...

The salicylic acid-induced protection of non-climacteric unripe pepper fruit against Colletotrichum gloeosporioides is similar to the resistance of ripe fruit.

20 Aug 2009 The anthracnose fungus Colletotrichum gloeosporioides deleteriously affects unripe pepper fruit, but not ripe fruit. Here, we show that the induction of local acquired resistance (LAR) by salicylic acid (SA), 2,6-dichloroisonicotinic acid, or ... Read more...
