Cocrystals of Praziquantel: Discovery by Network-Based Link Prediction

Abstract: Cocrystallization has been promoted as an attractive early development tool as it can change the physicochemical properties of a target compound and possibly enable the purification of single enantiomers from racemic compounds. In general, the identification of adequate cocrystallization candidates (or coformers) is troublesome and hampers the exploration of the solid-state landscape. For this reason, several computational tools have been introduced over the last two decades. In this study, cocrystals of Prazi… Show more

“…Therefore, it is very important to improve the water solubility of praziquantel to reduce the dosage of praziquantel for better development of pediatric drug use and to reduce the probability of drug resistance and adverse reactions, as well as to protect global public health security [ 7 ].The solubility of praziquantel can be improved by preparing praziquantel solid dispersions, lipid nanoparticles or cyclodextrin inclusion compounds, but are limited by instability during preparation or storage. Considering the advantages of cocrystal technology in improving the physical and chemical properties of compounds, many researchers have carried out related studies on PRA [ 8 , 9 , 10 , 11 ]. At present, 27 cocrystals of PRA have been reported in the Cambridge Structural Database (CSD), and based on the analysis of their structural information, the cocrystal coformers (CCFs) of PRA were all carboxylic acid compounds or compounds with polyphenol hydroxyl groups.…”

“…17 The latest study predicted 30 CCFs (mostly benzoic acid compounds with similar structures) that can form cocrystals with PRA using the network-based link prediction method, and 12 cocrystals were obtained. 18 Twenty-three PRA cocrystals have been reported in the Cambridge Crystallographic Data Center database. However, only the flavonoid cocrystals of PRA and PRA−L-MA had been subjected to solubility experiments, in which PRA's solubility decreased whereas PRA−L-MA's solubility increased in pH 1.0 medium.…”

“…In 2016, the R and S configurations of PRA were separated by forming a cocrystal between PRA and l -malic acid (PRA– l -MA) . The latest study predicted 30 CCFs (mostly benzoic acid compounds with similar structures) that can form cocrystals with PRA using the network-based link prediction method, and 12 cocrystals were obtained . Twenty-three PRA cocrystals have been reported in the Cambridge Crystallographic Data Center database.…”

“…Various ML models have been applied for cocrystal prediction, including support vector machines (SVMs) [30], multivariate adaptive regression splines [31], random forest (RF) [32], and network-based link-prediction [33]. In our previous work, we developed a virtual screening model based on an artificial neural network (ANN) algorithm for cocrystal prediction [34].…”
