WebJun 16, 2009 · A sigmoidal curve would fit the bill, and the experimentally determined binding curve is in fact steeply sigmoidal, like the red curve shown in Figure 3. The sigmoidal shape of the oxygen binding curve helps hemoglobin to achieve a high oxygen-delivery throughput. Sigmoidal binding curves occur if binding is cooperative. Binding curves showing the characteristically sigmoidal curves generated by using the Hill–Langmuir equation to model cooperative binding. Each curve corresponds to a different Hill coefficient, labeled to the curve's right. The vertical axis displays the proportion of the total number of receptors that have been bound … See more In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that … See more The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, $${\displaystyle n}$$ or $${\displaystyle n_{H}}$$, may describe cooperativity (or possibly other biochemical … See more The Hill and Hill–Langmuir equations are used extensively in pharmacology to quantify the functional parameters of a drug and are also … See more • Binding coefficient • Bjerrum plot • Cooperative binding • Gompertz curve See more The Hill–Langmuir equation is a special case of a rectangular hyperbola and is commonly expressed in the following ways. See more The Hill-Langmuir equation is derived similarly to the Michaelis Menten equation but incorporates the Hill coefficient. Consider a protein (), … See more Because of its assumption that ligand molecules bind to a receptor simultaneously, the Hill–Langmuir equation has been criticized as a physically … See more

WebCurcumin (5 μM) was used as the positive control. All reactions were performed in the presence of 0.1% of dimethyl sulfoxide, which was used as diluent for the compounds. The half maximal inhibitory concentration (IC 50) was established by adjusting the sigmoidal dose–response curve following GraphPad Prism 5 procedure. In silico molecular ... WebView publication.
