The stereoselectivity of various O- and N-methylations and of dehydrogenation of tetrahydropapaverine is discussed and there is evidence that enzymatic N-demethylations may take place to an appreciable extent.
The Effects of Two Different Ganoderma Species (Lingzhi) on Gene Expression in Human Monocytic THP-1 Cells
The results suggest that the common mode of action for lingzhi is complex; and different species of Ganoderma can modulate different pathways in human cells.
Production of Psilocybin in Psilocybe baeocystis Saprophytic Culture
The carpophores of six species of mushrooms were analyzed by TLC for indole derivatives. Three species, Psilocybe baeocystis , P. caerulipes , and P. stricttipes , were found to contain psilocybin,…
Baeocystin and norbaeocystin: new analogs of psilocybin from Psilocybe baeocystis.
Two new 4-phosphoryloxytryptamine derivatives have been isolated from Psilocybe baeocystis grown in submerged cultures. Using ultraviolet, infrared, and mass spectral analyses the structures have…
