Acta Societatis Botanicorum Poloniae, 2011 Nine known sesquiterpene lactones, including four lactucin-type guaianolides, four costuslactone-type guaianolides and one germacranolide, were isolated from roots of Lactuca sibirica (Asteraceae), six of which were glycoside derivatives.

Convergence of a meshless numerical method for a chemotaxis system with density-suppressed motility [PDF]
arXiv, 2023 This article studies a parabolic-elliptic system modelling the pattern formation in E. coli bacteria in response to a chemoattractant known as acylhomoserine lactone concentration (AHL). The system takes into account certain bacterial strains with motility regulation, and the parameters of the equations represent the bacterial logistic growth, AHL ...

Natural sesquiterpen lactones as acetylcholinesterase inhibitors [PDF]
Anais da Academia Brasileira de Ciências, 2014 Background and the purpose of the study: The amount of elder people who suffer from Alzheimer disease is continuously increasing every year. Cholinesterase inhibitors have shown to be effective in alleviating the symptoms of the disease, thus opening a field of research for these treatments.

Optimized nanodevice fabrication using clean transfer of graphene by polymer mixture: Experiments and Neural Network based simulations [PDF]
arXiv, 2023 In this study, we investigate both experimentally and computationally the molecular interactions of two distinct polymers with graphene. Our experimental findings indicate that the use of a polymer mixture reduces the transfer induced doping and strain in fabricated graphene devices as compared to conventional single polymer wet transfer. We found that

Catalytic Plasticity of Germacrene A Oxidase Underlies Sesquiterpene Lactone Diversification1[OPEN]
Plant Physiology, 2019 The striking catalytic plasticity of germacrene A oxidase, an evolutionary conserved enzyme in the Asteraceae, has led to the existence of diverse sesquiterpene lactones, including artemisinin.
