UPLC-QTOF-MS/MS and Antifungal Activity of a Fraction Enriched in Saponins From Sarcomphalus joazeiro Against Candida spp. [PDF]
Biomed ChromatogrABSTRACT The development of antifungal resistance is a complex process that involves the interaction between hosts, drugs, and microbial factors, all of which contribute to therapeutic ineffectiveness. For this reason, studies on natural products as possible therapeutic alternatives are increasingly necessary in order to gain a better understanding of ...

Acetaldehyde‐enkephalins: pronounced changes in the opiate activity of methionine‐enkephalin and leucine‐enkephalin on reaction with acetaldehyde [PDF]
FEBS Letters, 1980 We have shown that the two major endogenous opioid peptides, methionine-enkephalin and leucineenkephalin [ 1,2] (enkephalin [Met’] and enkephalin[Leu’]) rapidly react with acetaldehyde in aqueous buffers to give a stable ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin[Met’]’ and ‘acetaldehyde-enkephalin [Leu’]‘, respectively ...
