Partitioning and lipophilicity in quantitative structure-activity relationships. [PDF]

open access: yesEnvironmental Health Perspectives, 1985
The history of the relationship of biological activity to partition coefficient and related properties is briefly reviewed. The dominance of partition coefficient in quantitation of structure-activity relationships is emphasized, although the importance of other factors is also demonstrated.

Quantitative Structure-Activity Relationship of Fluorescent Probes and Their Intracellular Localizations

open access: yesChemosensors, 2023
The development of organelle-specific fluorescent probes has been impeded by the absence of a comprehensive understanding of the relationship between the physicochemical properties of fluorescent probes and their selectivity towards specific organelles ...

Quantitative structure–activity relationship based modeling of substituted indole Schiff bases as inhibitor of COX-2 [PDF]

open access: yes, 2013
We have performed the quantitative structure activity relationship (QSAR) study for N-1 and C-3 substituted indole shiff bases to understand the structural features that influence the inhibitory activity toward the cyclooxygenase-2 (COX-2) enzyme.

Quantitative structure–activity relationship study of antitubercular fluoroquinolones [PDF]

open access: yesMolecular Diversity, 2010
Quantitative structure-activity relationship study on three diverse sets of structurally similar fluoroquinolones was performed using a comprehensive set of molecular descriptors. Multiple linear regression technique was applied as a preprocessing tool to find the set of relevant descriptors (10) which are subsequently used in the artificial neural ...

Evaluating Molecular Properties Involved in Transport of Small Molecules in Stratum Corneum: A Quantitative Structure-Activity Relationship for Skin Permeability

open access: yesMolecules, 2018
The skin permeability (Kp) defines the rate of a chemical penetrating across the stratum corneum. This value is widely used to quantitatively describe the transport of molecules in the outermost layer of epidermal skin and indicate the significance of ...
