Q-rényi’s divergence as a possible chemical similarity criterion

In this work, we introduce the q-Rényi’s divergence, which results from the conjunction of Rényi’s divergence and Jackson’s integral. The resultant equation can be employed as a measure of chemical similarity, which consists of comparing two or more chemical species with a set of molecules that have been characterized to find two or more molecules that could have similar chemical or physical properties. To carry out our study, we applied q-Rényi’s divergence using a set of Tetrodotoxin variants and a set of 1641 organic molecules. Our results suggest that q-Rényi’s divergence could be a valuable tool to complement chemical similarity studies.
