Efficient syntheses of 2,3-disubstituted natural quinazolinones via iridium catalysis.

Natural products sclerotigenin, pegamine, deoxyvasicinone, mackinazolinone, and rutaecarpine were synthesized. Core quinazolinone structures were constructed via Ir catalysis.

Studies on Biological Oxidations

Pyruvic acid is one of the most reactive substances among those of importance in cellular metabolism. When carbohydrate is split during fermentation, pyruvic acid is the main end-product of the resulting series of phosphorylated oxidation-reductions. It thus becomes the immediate source for the formation of both lactic acid and alcohol. Pyruvic acid is decarboxylated by yeast; it may react with...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
