The Effects of Sesquiterpene Lactones on the Differentiation of Human or Animal Cells Cultured In-Vitro: A Critical Systematic Review

open access: yesFrontiers in Pharmacology, 2022
Cellular differentiation is pivotal in health and disease. Interfering with the process of differentiation, such as inhibiting the differentiation of adipocytes and inducing the differentiation of cancer cells, is considered a therapeutic approach ...

Syntheses of Unsaturated Lactones

open access: bronzeAgricultural and Biological Chemistry, 1969
6-Pentyl-α-pyrone, 6-propyl-α-pyrone and 4-decenoic acid-δ-lactone were prepared, and the nature of their flavors was investigated. Unsaturated lactones having the best flavorous nature as a butter or butter cake flavor among the lactones having double bond at various site, were 2-ene-δ-lactones which have a double bond at the α-position of the lactone

Encapsulation of flavours into Yarrowia lipolytica active yeast cells. Fluorescence study of the lipid droplets morphology and steryl/sterol balance during the shock

open access: yesAIMS Biophysics, 2022
Yeast are a powerful material for the encapsulation of compounds. Usually, yeast used as capsules are inactivated by the encapsulation treatment, which is stressful to cells.

Biocatalytic Synthesis of Stereospecific Triketide Lactones using Polyketide Synthases [PDF]

open access: yes, 2016
Polyketide synthases are modular enzymes that create and modify large acyl chains. The domains and modules of polyketide synthases allow us to create molecules that resemble naturally occurring products by applying a biocatalytic in vitro in vivo ...

Synthesis and biological evaluation of novel N-α-haloacylated homoserine lactones as quorum sensing modulators [PDF]

open access: yes, 2014
Novel N-α-haloacylated homoserine lactones, in which a halogen atom was introduced at the α-position of the carbonyl function of the N-acyl chain, have been studied as quorum sensing (QS) modulators and compared with a library of natural N-acylated ...
