Anti-Neurodegenerating Activity: Structure–Activity Relationship Analysis of Flavonoids
Molecules, 2023 An anti-neurodegeneration activity study was carried out for 80 flavonoid compounds. The structure–activity analysis of the structures was carried out by performing three different anti-neurodegeneration screening tests, showing that in these structures,

Styrylchromones: Biological Activities and Structure‐Activity Relationship [PDF]
ChemMedChem, 2021 AbstractStyrylchromones (SC) are a group of oxygen‐containing heterocyclic compounds, which are characterized by the attachment of a styryl group to the chromone core. SC can be found in nature or can be chemically synthesized in the laboratory. As their presence in nature is scarce, the synthetic origin is the most common. Two types of SC are known: 2‐

Modeling Structure–Activity Relationship of AMPK Activation [PDF]
Molecules, 2021 The adenosine monophosphate activated protein kinase (AMPK) is critical in the regulation of important cellular functions such as lipid, glucose, and protein metabolism; mitochondrial biogenesis and autophagy; and cellular growth. In many diseases—such as metabolic syndrome, obesity, diabetes, and also cancer—activation of AMPK is beneficial. Therefore,

QnrS1 structure-activity relationships [PDF]
Journal of Antimicrobial Chemotherapy, 2014 Loop B is important for low-level quinolone resistance conferred by Qnr proteins. The role of individual amino acids within QnrS1 loop B in quinolone resistance and gyrase protection was assessed.qnrS1 and 11 qnrS1 alleles with site-directed Ala mutations in loop B were expressed in Escherichia coli BL21(DE3) and proteins were purified by affinity ...

Structure-activity relationships of the nikkomycins [PDF]
Journal of General Microbiology, 1991 The structure-activity relationships of different nikkomycins were studied to evaluate the structural requirements for a potent chitin synthase inhibitor. We investigated the transport of the nikkomycins via the peptide transport system of the yeast Yarrowia lipolytica and determined the kinetic parameters for nikkomycin Z uptake [Km = 24 microM, Vmax =
