Synthesis and Quantitative Structure–Activity Relationship of Imidazotetrazine Prodrugs with Activity Independent of O6-Methylguanine-DNA-methyltransferase, DNA Mismatch Repair and p53. [PDF]

, 2013
The antitumor prodrug Temozolomide is compromised by its dependence for activity on DNA mismatch repair (MMR) and the repair of the chemosensitive DNA lesion, O6-methylguanine (O6-MeG), by O6-methylguanine-DNA-methyltransferase (EC 2.1.1.63, MGMT). Tumor

Quantitative structure activity relationship study of p38α MAP kinase inhibitors

Arabian Journal of Chemistry, 2017
The quantitative structure activity relationship (QSAR) of the novel pyrazole derivatives as inhibitors of p38α mitogen activated protein (MAP) kinase was studied. The suitable set of the molecular descriptors was calculated and the important descriptors

The problem of the relationship qualitative data, quantitative data in general statistics [PDF]

arXiv, 2022
The disjunction between nature and science is studied, together with the need to modify the conception of natural science vs artificial science, related to the perspective of objectivity and subjectivity, to end with the explanation of the process of polarization of methodologies and the relationship between mixed data, as a possibility of unification ...

An illustrative example of the relationship between dissipation and relative entropy [PDF]

Phys. Rev. E 79, 021106 (2009), 2009
Kawai, Parrondo, and Van den Broeck [Phys. Rev. Lett. 98, 080602 (2007)] have recently established a quantitative relationship between dissipated work and a microscopic, information-theoretic measure of irreversibility. We illustrate this result using the exactly solvable system of a Brownian particle in a dragged harmonic trap.

Prediction of terpenoid toxicity based on a quantitative structure–activity relationship model [PDF]

, 2019
Terpenoids, including monoterpenoids (C10), norisoprenoids (C13), and sesquiterpenoids (C15), constitute a large group of plant-derived naturally occurring secondary metabolites with highly diverse chemical structures. A quantitative structure–activity

Imputation versus prediction: applications in machine learning for drug discovery [PDF]

, 2020
Imputation is a powerful statistical method that is distinct from the predictive modelling techniques more commonly used in drug discovery. Imputation uses sparse experimental data in an incomplete dataset to predict missing values by leveraging ...

Reduction of a biochemical network mathematical model by means of approximating activators and inhibitors as perfect inverse relationships [PDF]

arXiv, 2023
Models of biochemical networks are usually presented as connected graphs where vertices indicate proteins and edges are drawn to indicate activation or inhibition relationships. These diagrams are useful for drawing qualitative conclusions from the identification of topological features, for example positive and negative feedback loops.
