High logp means
WebIt has been shown that the log P of a compound can be determined by the sum of its non-overlapping molecular fragments (defined as one or more atoms covalently bound to each other within the molecule). Fragmentary log P values have been determined in a statistical method analogous to the atomic methods (least squares fitting to a training set). WebLogP. Definition: A measure of the preference of a compound to dissolve in either water or an organic solvent (such as octanol) when uncharged. More technically, it is the logarithm …

According to Lipinski’s Rule of Five, this usually means the partition coefficient should be positive, but less than 100 000 to 1 (or log 10 PC=5). 105,106 In another statistical study, the log PC was seen to be the best at log 10 PC<3. 107.
WebNov 14, 2004 · The area logP is large, the accuracy is very high. But the area logP<0 the accuracy is not so high. In that area, emulsion happen and hard to separate. I always wonder why I can estimate logP with this simple group additivity method. I found the answer. When I was developing QSPR model to predict logP, I happened to plot logP vs molecular volume. WebLogP is the log of the partition coefficient of a solute between octanol and water, at near infinite dilution. LogP is widely used in drug discovery and development as an indicator of potential utility of a solute as a drug.
WebJun 6, 2024 · Thus, higher logP means that a smaller concentration of the molecule is available in the water phase of a system, which makes it more lipophilic or hydrophobic. 2) Molecular weight Molecular weight (MolWt) is simply the total mass of a … WebPierce Biotechnology PO Box 117 (815) 968-0747 www.thermo.com/pierce 3747 N.
