Special Issue Information

Dear Colleagues,

Since the first attempts at structure-based drug design about four decades ago, molecular modelling techniques for drug design have developed enormously, along with the increasing computational power and structural and biological information on active compounds and potential target molecules. Currently, molecular modeling can be considered an integral component of the contemporary drug discovery and development process. Rational target-based drug development projects benefit significantly from understanding the essential ligand-receptor interactions for designing a potent and efficacious drug to the desired target.

Although current modeling techniques can give important insights and speed up the drug discovery and design stages significantly, there are still many challenges in, for example, predicting accurate ligand binding energies, considering protein flexibility upon ligand binding, or mapping off-target effects of designed compounds. Nowadays, there is also a need for modelling bigger entities, such as antibodies and nanoparticles, as well as targeting macromolecular interfaces.     

The aim of this Special Issue is to present a contemporary overview of recent developments in the field of molecular modeling in the context of modern drug design. Reviews, full papers, and short communications, covering the methodological and theoretical aspects of the current trends in molecular modeling are all welcome. The submission of papers addressing the topics listed below is particularly encouraged.

Squalene synthase (SQS), a key downstream enzyme involved in the cholesterol biosynthetic pathway, plays an important role in treating hyperlipidemia. Compared to statins, SQS inhibitors have shown a very significant lipid-lowering effect and do not cause myotoxicity. Thus, the paper aims to discover potential SQS inhibitors from Traditional Chinese Medicine (TCM) by the combination of molecular modeling methods and biological assays. In this study, cynarin was selected as a potential SQS inhibitor candidate compound based on its pharmacophoric properties, molecular docking studies and molecular dynamics (MD) simulations. Cynarin could form hydrophobic interactions with PHE54, LEU211, LEU183 and PRO292, which are regarded as important interactions for the SQS inhibitors. In addition, the lipid-lowering effect of cynarin was tested in sodium oleate-induced HepG2 cells by decreasing the lipidemic parameter triglyceride (TG) level by 22.50%. Finally. cynarin was reversely screened against other anti-hyperlipidemia targets which existed in HepG2 cells and cynarin was unable to map with the pharmacophore of these targets, which indicated that the lipid-lowering effects of cynarin might be due to the inhibition of SQS. This study discovered cynarin is a potential SQS inhibitor from TCM, which could be further clinically explored for the treatment of hyperlipidemia. Full article

Title: Theoretical Model of EphA2-Ephrin A1 Inhibition

Abstract: This work aims at the theoretical description of EphA2-ephrinA1 inhibition by small molecules. Recently proposed ab initio-based scoring models, comprising long-range components of interaction energy, is tested on lithocholic acid class inhibitors of this protein-protein interaction (PPI) against common empirical descriptors. We show that although limited to compounds with similar solvation energy, the ab initio model is able to rank the set of selected inhibitors more effectively than empirical scoring functions, aiding the design of novel compounds.
