General interests and strategy
My general research goal is to develop methods for molecular simulations and apply such methods in drug design projects in collaboration with experimentalists. As such, my research has a fundamental leg consisting of method development and an applied leg wherein I assist my collaborators in answering concrete research questions. In the context of starting a new research program at the VUB, the applied leg gets the biggest weight, as this type of research is a relatively reliable and steady source of research output. Specifically, we are currently focusing on starting a number of collaborations with "neighboring" groups, as listed in the section New applied research. During this first "build-up" stage, the fundamental leg consists mostly of assisting my former group at the University of Maryland, Baltimore with sustaining highly popular Force Field development projects that I started with them; see the section Ongoing method development. The steady stream of research output established in the first stage creates the breathing room to engage in more innovative (but also somewhat more risky) fundamental research, which is elaborated in the section Future method development.
Applied research projects
New applied research
Modulators for the Cystine/Glutamate Antiporter System xc⁻ (Sxc⁻)
The Cystine/Glutamate Antiporter System xc⁻ (Sxc⁻) plays an important role in different parts of body, especially in central nervous system. Accordingly, its inhibition has been proposed as therapeutic strategy for several disease states such as cancer-induced bone pain and a number of neurological disorders, some of which are the subject of research led by A. Massie and I. Smolders at our fellow research unit FASC. Such research is hindered by a relative scarcity of specific inhibitors for Sxc⁻. Accordingly, the aim of this research project is to design novel selective Sxc⁻ modulators using target-based drug design strategies. A special challenge in this project is that, being a gradient-driven transporter, Sxc⁻ has a rather low binding affinity for its natural substrates. Consequently, searching for molecules that bind the protein in a similar way as its substrates will not yield strong inhibitors if the proposed molecules act as substrate analogs and activate the selective transport pathway. Therefore, obtaining detailed knowledge of this pathway seems to be helpful in guiding our drug design project in addition to providing fundamental insights into a complex and interesting biochemical process. Indeed, the ability of transporters in the SLC7 family to effect selective transport based on weak-binding ligands poses a fundamental riddle that is not yet resolved in atomic detail. A first article on this subject has been published35 and more results are in the pipeline.
Selective glucocorticoid receptor modulators
Numerous biomedical applications have been proposed for the selective modulation of the glucocorticoid receptor, specifically the selective activation or inhibition of its so-called transrepression and transactivation pathways. Through substantial drug design efforts, a number of compounds have been identified that display some of these properties. The present research project aims to zoom in on the different protein-protein interactions that lie at the basis of these pathways, including dimerization. This will allow the identification of strategies to develop highly selective glucocorticoid receptor modulators using target-based drug design methods. In particular, we aim to find:
Novel compounds that modulate the transrepression pathway with sufficient selectivity to be of use in the search for therapies for stress-related mental disorders, led by D. De bundel at at our fellow research unit FASC. In order to achieve this, molecules may need to interact with other parts of the receptor than the traditional corticoid binding pocket.
Ways to chemically trigger the transactivation pathway without transrepression. Compounds that have this particular effect do not exist yet, but could be used to modulate the proliferation of beta cells, which is the subject of research by K. Hellemans et al. at our unit Diabetes Pathology and Cell Therapy.
Molecular mechanisms of separation on chiral High-Pressure Liquid Chromatography (HPLC) columns
HPLC with chiral columns is a rare generally applicable technique for the separation of enantiomers, which is of high and increasing importance in drug discovery, production and analysis. For this reason, it forms a prominent line of research in the research group FABI of which I am part. Computer models for predicting chiral separations are largely confined to a narrow chemical space defined by their training set.33 In our opinion, the main reasons for this are (1) a relatively limited computational tool chest for characterizing chiral properties of analytes and (2) incomplete insight into the molecular mechanism for the enantioselectivity of common stationary phases such as derivatized amylose and cellulose. The latter point represents a relative lack of fundamental knowledge, which we aim to address by studying the molecular mechanisms of chiral separation on these stationary phases with Molecular Dynamics simulation techniques. This study leverages our previously established expertise in force fields for carbohydrates and small organic molecules as well as advanced methods for trajectory analysis. In parallel, we seek to address point (1) above by developing new chiral molecular descriptors that are more strongly anchored in physical properties than the presently available chiral descriptors. Results of a small-scale descriptor development pilot project have been published36 and will be followed by more systematic larger-scale studies. In addition, it is anticipated that the availability of new insights from the fundamental leg of this study will provide inspiration for later generations of chiral descriptors.
Ongoing applied research: mimetics of secondary structure elements in proteins
My first contact with peptidomimetics mimicking specific secondary structure motifs was in the Dirk Tourwé lab, where this was a major research topic, and where I assisted in conformational studies aimed at determining the β-turn propensity of 4-Amino-1,2,4,5-tetrahydro-2-benzazepin-3-ones and derivatives.5 Several years later, when working in the MacKerell lab, I became involved in Steven Fletcher's research on α-helix and β-sheet mimetics. In this context, I assisted in the design of oligoamide-foldamer-based α-helix mimetics that target the interaction of the BCL-xL oncoprotein with the pro-apoptotic BAK protein,13,18 as well as the design of a 1,2-diphenylacetylene-based scaffold for amphipathic α-helix mimetics with potential applications in binding the Mcl-1 oncoprotein.19 Work on a β-sheet mimetic with therapeutic potential against cancer through a different mechanism is also in progress.
Fundamental research projects (method development)
Future method development: next-generation potential energy functions
Even though a wide variety of Potential Energy Functions (PEF) for molecular mechanics are described in the literature, a large majority of biomolecular simulations are performed using force fields that are based on the relatively crude Class I PEF. Reasons for this are (1) computational cost, (2) the fact that most of the refinements in more sophisticated (in particular class II and III) PEF do not compellingly improve the properties that are commonly studied in life science and (3) the combinatorial explosion of force field parameters associated with extra terms in the PEF, which yields a complex parameter optimization problem with a shortage of relevant target data. Yet, specific shortcomings of the Class I additive PEF have become increasingly obvious in the last decades, prompting the development of potential energy terms for polarization. While still accounting for a minority of biomolecular simulations, the resulting polarizable force fields have enjoyed a steady increase in popularity. In line with points (1) and (3) above, this can for a large part be attributed to the ever increasing availability of computer power and efficient computational methods, which have not only proven instrumental in the parametrization of polarizable force fields, but also mitigate the computational cost of their application. Further along this line of thinking, it is our opinion that polarization is merely the tip of an iceberg of PEF improvements that address real shortcomings in the field and have come within reach through new insights, increased computational power and improved methods. Accordingly, we are planning to critically explore the ways current force fields can be improved, with a pragmatic focus on
Concerning the last point, in light of the large demand for parameters for "non-standard" chemical entities, straightforward parametrization is indeed a highly desirable property. It may at first glance seem counterintuitive that a more sophisticated force field would be easier to parametrize, but it should be kept in mind that a large part of the difficulty in the development of present-generation force fields is the careful balancing of errors induced by the PEF's shortcomings, so that properties of interest are accurately reproduced. This specific effort is expected to decrease when using a PEF that has less fundamental shortcoming in the first place, as seen at a modest level during the development of polarizable force fields.
- only improving system properties that are of actual interest in life science,
- keeping the associated computational cost within acceptable limits,
- building a next-generation force field that should ideally be more straightforward to parametrize than the current generation.
Ongoing method development (started at University of Maryland, Baltimore)
Empirical force fields20 are presently the only computational methods fast enough to routinely perform molecular dynamics simulations of large chemical systems, such as proteins, on relevant time scales. The CHARMM force field is widely used for simulating biomolecular systems, being capable of representing proteins, nucleic acids, lipids and carbohydrates.22 The CHARMM General Force Field (CGenFF) adds to this a wide range of chemical groups present in biomolecules and drug-like molecules including a large number of heterocyclic scaffolds. CGenFF thus makes it possible to perform "all-CHARM" simulations on drug-target interactions thereby extending the utility of CHARMM force fields to medicinally relevant systems. As a validation, CGenFF was shown to accurately reproduce geometric, vibrational and energetic data, including interactions with water, as well as satisfactorily reproducing the experimental molecular volumes for 111 pure solvents and heats of vaporization of 95 molecules.9
The parametrization philosophy behind the force field focuses on quality at the expense of transferability, with the implementation concentrating on an extensible force field. This is testified by our tutorials that take the reader through the parametrization process in a step-by-step fashion.
Following the first release of CGenFF, significant improvements in the force field's coverage of chemical space have been made15,29 and virtual particles were introduced to better capture halogen bonds.31 In parallel, the CGenFF program was developed. This program performs atom typing and assignment of parameters and charges by analogy in a fully automated fashion. The atom typer is deterministic and based on a programmable decision tree, making it easy to implement complex atom typing rules and to update the atom typing scheme as the force field grows.16 Assignment of bonded parameters is based on substituting atom types in the definition of the desired parameter. A penalty is associated with every substitution and the existing parameter with the lowest total penalty is chosen as an approximation for the desired parameter; the "penalty score" is returned to the user as a measure for the accuracy of the approximation. Charges are assigned using an extended bond-charge increment scheme that is able to capture short- and medium-range inductive and mesomeric effects.17

Automatic fitting of Molecular Mechanics parameters
Automated methods for force field parametrization have attracted renewed interest of the community, but the robustness issues associated with the often ill-conditioned nature of parameter optimization have been vastly underappreciated in the recent literature. We developed a Linear Least Squares (LLS) procedure that is able to simultaneously fit all the bonded parameters in a Class I force field and includes a novel restraining strategy that overcomes robustness issues in the LLS fitting of bonded parameters while minimally impacting the fitted values of well-behaved parameters.26 The same procedure was also used for the fitting of the bond-charge increments in the next release of the CGenFF program, illustrating the method's potential for robustly solving general LLS problems beyond force field parametrization. The fitting part of the methodology was implemented in a C program named "lsfitpar" is available to the community under the Affero GPL. It hoped it will become an important part of the sprawling ecosystem of automatic parametrization interfaces. Future directions include further automation, validation of the methodology for the purpose of charge fitting, testing of its ability to use Monte Carlo conformational sampling data and extending the program's feature set.
Inhibition of the BCL6/SMRT interaction
This project is a collaborative effort involving the Molecular Biology group of Ari Melnick, the X-ray Crystallography and Structural Biology group of Gil Privé, the Organic Chemistry group of Andrew Coop and Alex MacKerell's CADD center. The aim of this collaboration is to develop novel anti-cancer drugs that target the BCL6 oncogenic transcriptional repressor. As part of Alex MacKerell's group, my role consisted mainly of assisting in the discovery of new leads by means of in silico screening of libraries of commercially available compounds. In this context, I employed both ligand-based and structure-based drug design strategies. In other words, I identified new leads by their chemical homology to known inhibitors as well as their binding affinity to relevant parts of BCL6, as predicted by docking studies.30
Post-HF and post-DFT evaluation of the dispersion energy
Dispersion interactions play a fundamental role in physics, chemistry and biology, where they appear, for example, in π-π stacking interactions contributing to the structure, catalysis and inhibition, of proteins. Therefore, a theoretical description of these interactions would be desirable. This is not easily accomplished because dispersion interactions can only be described at a level of theory that includes electron correlation. Since current Density Functional Theory (DFT) methods do not correctly reproduce disperion interactions, at least second order Møller-Plesset (MP2) theory must be used. However, systems with a biologically relevant size are currently far beyond the computational reach of this method. Therefore, our goal is to include a "semi-empirical" dispersion correction on top of the DFT energy. This is accomplished by combining a recent approximation scheme by Becke and Johnson with a Hirschfeld-type scheme for partitioning molecular polarizabilities into atomic contributions.7,8,10,12
Cyberenvironment for MM and SE parameter optimization
The ParamChem project (full title: "Extensible Cyberenvironments for Empirical and Semiempirical Hamiltonian Parameter Optimization and Dissemination") is an NSF sponsored initiative to develop an integrated cyber environment to address the simulation needs of molecular sciences. The proposed infrastructure will provide reference data organizers and generators as well as workflows for automatic parameterization of Molecular Mechanics (MM) Force Fields as well as Semi-Empirical (SE) methods. A comprehensive utility for the optimization and testing of parameters in Force Fields and Semi-Empirical models will be set up, allowing experts in these fields to develop novel models of higher accuracy in shorter time periods. These models can then be made available to the computational chemistry community at large via a parameter database. This will make it easier for computational chemists to find an appropriate model for the system they are studying, and, if necessary, to extend the model to novel functional groups using automated utilities. Currently, we're working on automatic force field parameterization in the context of CGenFF. In the long run, many other Molecular Mechanics as well as Semi-Empirical models will be integrated. From this, a wide range of parameters encompassing biological, organic and inorganic species will be accessible for direct use or further optimization.
