Abstract: A variety of computational tools that are used to assist drug design are reviewed. Particular emphasis is given to the limitations and merits of different methodologies. Recently, a number of general methods have been proposed for clustering compounds in classes of drug like and non-drug-like molecules. The usefulness of this classification for drug design is discussed. The estimation of (relative) binding affinities is from a theoretical point of view the most challenging part of ligand design. We review three methods for the estimation of binding energies. Firstly, quantitative st

Abstract (sommario):

Computer-aided ligand design is an active, challenging, and multidisciplinary research field that blends knowledge of biochemistry, physics, and computer sciences. Whenever it is possible to experimentally determine or to model the three-dimensional structure of a pharmacologically relevant enzyme or receptor, computational approaches can be used to design specific high-affinity ligands. This article describes methods, applications, and perspectives of computer-assisted ligand design.

Abstract (sommario):

RNA-based therapeutics hold a great promise in treating a variety of diseases. However, double-stranded RNAs (dsRNAs) are inherently unstable, highly charged, and stiff macromolecules that require a delivery vehicle. Cationic ligand functionalized gold nanoparticles (AuNPs) are able to compact nucleic acids and assist in RNA delivery. Here, we use large-scale all-atom molecular dynamics simulations to show that correlations between ligand length, metal core size, and ligand excess free volume control the ability of nanoparticles to bend dsRNA far below its persistence length.

Abstract (sommario):

The process of preclinical drug discovery consists of two steps: finding of initial hits (binding ligands to a medicinal relevant target, usually a protein) and lead optimization. Nuclear magnetic resonance spectroscopy is a powerful tool that can provide valuable information to every step of drug development. NMR is commonly used for characterizing the structure and molecular dynamics of target or ligand molecules. During the structure-based lead optimization, NMR provides insight into the structural and dynamical properties of the target-ligand complex. Recently, the use of NMR in the lead f

Abstract (sommario):

An important feature necessary for biological stability of gold nanoparticles is resistance to ligand exchange. Here, we design and synthesize self-assembled monolayers of mixtures of small ligands on gold nanoparticles promoting high resistance to ligand exchange. We use as ligands short thiolated peptidols, e.g. H-CVVVT-ol, and ethylene glycol terminated alkane thiols (HS-C11-EG4). We present a straightforward method to evaluate the relative stability of each ligand shell against ligand exchange with small thiolated molecules. The results show that a ligand with a ‘thin’ stem, such as HS-C11

Abstract (sommario):

Although the adding multifunction ligand can regulate the perovskite property, the effect of the enhancement depends on the ligand structure. In this paper, the polarity of aromatic ligand is regulated by design strategy — introducing fluorine (F) atom and alkyl chain (R-NH3). Those ligands affect the structure, photoelectric properties and energy state of formamidinium (FAPbI3) perovskite surface. The ligand polarity increases with more F atoms and R-NH3 length, which increases fermi energy and then decreasing band gap and increasing work function (WF). The CF3-PEA/BEA obtains the higher pola

Abstract (sommario):

The natural bite angle concept is examined using N,N′-bisphosphino urea ligands as rigid scaffolds. The ligand has an upper limit of about 95° for the observed bite angle in chelate complexes, but prefers a much lower one. The ligand can be described as possessing downward flexibility. The dependence of the bite angle on the P—P distance within the ligand and the M—P bond length is illustrated. The metal tries to force the ligand into its own preferred structure, whereas the ligand wants to achieve a short P—P distance. A truly rigid ligand such as the N,N′-bisphosphino urea family is thus see

The ability to design drugs (so-called ‘rational drug design’) has been one of the long-term objectives of chemistry for 50 years. It is an exceptionally difficult problem, and many of its parts lie outside the expertise of chemistry. The much more limited problem – how to design tight-binding ligands (rational ligand design) – would seem to be one that chemistry could solve, but has also proved remarkably recalcitrant. The question is ‘Why is it so difficult?’ and the answer is ‘We still don't entirely know’. This perspective discusses some of the technical issues – potential functions, prote

Abstract (sommario):

G protein-coupled receptors represent the largest family of human membrane proteins and are modulated by a variety of drugs and endogenous ligands. Molecular modeling techniques, especially enhanced sampling methods, have provided significant insight into the mechanism of GPCR–ligand recognition. Notably, the crucial role of the membrane in the ligand-receptor association process has earned much attention. Additionally, docking, together with more accurate free energy calculation methods, is playing an important role in the design of novel compounds targeting GPCRs. Here, we summarize the rece

Abstract (sommario):

An investigation of the interaction of zinc(II), cadmium(II), silver(I) and lead(II) with a series of mixed-donor dibenzo-substituted macrocyclic ligands, incorporating O2N3-, O2N4-, O3N2-, O3N3-, O4N2- and O2N3S-donor sets, has been carried out. The log K values for the respective complexes in 95% methanol (I = 0·1; Et4NClO4, 25°C) have been determined potentiometrically. All ligands form 1 : 1 (metal/ligand) complexes with the above metal ions although in isolated cases species of type MLH2+ were also observed. An investigation of the effect of variation of ligand structure on the respective

Abstract (sommario):

Abstract Motivation: Predictive tools that model protein–ligand binding on demand are needed to promote ligand research in an innovative drug-design environment. However, it takes considerable time and effort to develop predictive tools that can be applied to individual ligands. An automated production pipeline that can rapidly and efficiently develop user-friendly protein–ligand binding predictive tools would be useful. Results: We developed a system for automatically generating protein–ligand binding predictions. Implementation of this system in a pipeline of Semantic Web technique-based web

Abstract (sommario):

In multicellular organisms, antiviral defense mechanisms evoke a reliable collective immune response despite the noisy nature of biochemical communication between tissue cells. A molecular hub of this response, the interferon I receptor (IFNAR), discriminates between ligand types by their affinity regardless of concentration. To understand how ligand type can be decoded robustly by a single receptor, we frame ligand discrimination as an information-theoretic problem and systematically compare the major classes of receptor architectures: allosteric, homodimerizing, and heterodimerizing. We demo

Abstract (sommario):

In this review, we report NMR studies of ligand–GPCR interactions, including both ligand-observed and protein-observed NMR experiments. Published studies exemplify how NMR can be used as a powerful tool to design novel GPCR ligands and investigate the ligand-induced conformational changes of GPCRs. The strength of NMR also lies in its capability to explore the diverse signaling pathways and probe the allosteric modulation of these highly dynamic receptors. By offering unique opportunities for the identification, structural and functional characterization of GPCR ligands, NMR will likely play a

Abstract (sommario):

Recent advances in experimental techniques have led to an enormous explosion of available data about protein–ligand complexes. To exploit the information that is hidden in these large data, collection tools for managing and accessing huge data collections are needed. This paper discusses databases for protein–ligand data which are accessibleviathe World Wide Web. A strong focus is placed on the ReLiBase database system which is a new three-dimensional database for storing and analysing structures of protein–ligand complexes currently deposited in the Brookhaven Protein Data Bank (PDB).

Abstract (sommario):

Taguchi method was used to optimize peptide ligand structure using the H-2/TCR complex (PDB ID 2Z31). This approach greatly reduces the number of experiments that are required to analyze the contribution of various amino acid residues for each position into ligand molecule. Taguchi matrix was used to design a set of peptide ligands for molecular docking and molecular mechanics energy minimization. This approach allowed creating a new peptide structure with lower molecular mechanics energy than native peptide and demonstrates the applicability of the Taguchi method for peptide ligand optimizati

Abstract (sommario):

Traditionally, the thermodynamic values of affinity are considered as the main criterion for the development of new drugs. Usually, these values for drugs are measured in vitro at steady concentrations of the receptor and ligand, which are differed from in vivo environment. Recent studies have shown that the kinetics of the process of drug binding to its receptor make significant contribution in the drug effectiveness. This has increased attention in characterizing and predicting the rate constants of association and dissociation of the receptor ligand at the stage of preclinical studies of dr
