A rare glutamine derivative, hemerocallisamine I (1), was isolated from the methanolic extract of the flower buds of daylily, together with a new pyrrole alkaloid hemerocallisamine II (2) and a new γ-lactam derivative, hemerocallisamine III (3). The chemical structures of the new compounds were elucidated on the basis of chemical and physicochemical evidence. For hemerocallisamine I (1), the absolute configuration was determined by Mo-Kα X-ray crystallographic analysis. This is the first report…

Glutamine and alanyl-glutamine accelerate the recovery from 5-fluorouracil-induced experimental oral mucositis in hamster
TLDR
Glutamine or alanyl-glutamine accelerated the mucosal recovery increasing mucosal tissue glutathione stores, reducing inflammatory parameters and speeding reepithelization, and reduced the myeloperoxidase activity on day 14, but not on day 10.
