The research team from Kazan University has announced that it is working on a computational model able to predict the properties of new molecules based on the analysis of fundamental chemical laws. The project was supported by the Russian Science Foundation.
Tautomeric Transformations
Timur Madzhidov, co-author, associate professor, explains, “
We offered a way to insert the preexisting chemical equations into some frameworks of machine learning. It was tested on the predictions of tautomeric constants and acidity, which are linked by the Kabachnik equation. Using the functional interdependency between them, the neural network learns how to predict both these properties.”
Prototropic tautomerism is the phenomenon of reversible isomerism, in which isomers (substances having the same qualitative and quantitative composition but differing in structure and properties) easily transition into each other due to the transfer of a hydrogen atom.
“
Tautomeric transformations are very common for organic compounds, being known for about half of all discovered compounds. For example, one of the mechanisms of spontaneous mutations is tied to the tautomeric transformations of DNA nucleic base. That why tautomerism must be taken into account when registering new compounds, during the computer design of new medications and the search for molecules with preconditioned properties,” adds Madzhidov.
Proposed Applications of Research
The results of this research can help increase the precision of prediction of physicochemical properties of designed medication and materials, as well as correctly forecast the parameters of chemical reactions.
