In the title CuIIcomplex, [Cu(C19H14O3P)2(C3H7NO)(H2O)2], the molecule is bisected by a twofold axis relating the two 2-(diphenylphosphoryl)benzoate (ODPPB) ligands. The asymmetric unit consists of a CuIImetal centre on the symmetry axis, an ODPPB ligand, one water ligand and one dimethylformamide (DMF) ligand (disordered around the twofold axis). The CuIIion has fivefold coordination provided by two carboxylate O atoms from two ODPPB ligands, two O atoms from two coordinated water molecules and another O atom from a (disordered) DMF molecule, giving a CuO5square-pyramidal coordination geometr

AXL kinase is a promising target in novel drug discovery for cancer. A ligand-based pharmacophore model was generated with the Pharmit web server. Its inbuilt PubChem molecule database was screened and led to 408 candidate molecules. Docking of the AXL kinase active sites with the identified list of candidate molecules was carried out with Autodock Vina docking software.

To better understand the biological implications of the association of ligand with major histocompatibility complex class I molecules, we have studied the Ld molecule of the mouse. The culturing of various nonselected cell lines with three different known Ld peptide ligands resulted in a two- to fourfold specific increase in surface Ld expression as detected by 10 of 11 different monoclonal antibodies (mAbs) recognizing Ld epitopes. These findings suggest that Ld molecules are not saturated with endogenous peptide ligands and thus have accessible binding sites. Exploiting this feature of Ld we

Ligand binding to receptors is one of the most important regulatory elements in biology as it is the initiating step in signaling pathways and cascades. Thus, precisely localizing binding sites and measuring interaction forces between cognate receptor–ligand pairs leads to new insights into the molecular recognition involved in these processes.

Cells communicate with one another through a huge variety of extracellular soluble signaling molecules. A common method in biology to investigate the signaling pathways is to inactivate the gene coding the interested ligand or receptor from cells using modern DNA technology, known as gene knockout. Even though very effective, however, gene knockout is a time-consuming and cost-prohibitive process and requires huge amount of efforts to conduct. Here we present a simple method to probe the extracellular signaling pathways through engineering a semi-permeable barrier between two cell populations.

Traditionally, this has been accomplished by eliminating the gene in the cell that is responsible for coding the targeted ligand/receptor by using modern DNA technology such as gene knockout; however, this process is expensive, time-consuming, and labor intensiv

Cardiac amyloidosis is a clinical pathology, usually of a genetically mediated nature, initiated by the formation of amyloid fibrils, that lead to death. The number of clinically used molecules for the treatment of cardiac amyloidosis is very limited with strong side effects (for example, tafamidis and diflunisal). In this study, the methods of molecular modeling and computer docking of ligands using ICM-pro (Molsoft LLS, USA) were used to evaluate for the first time the level of side binding of small molecules possessing in vivo cardiovascular activity into the ligand-binding domains of 136 p

Cytochrome P450 17A1 (CYP17A1) is a critically important enzyme in humans that catalyzes the formation of all endogenous androgens. This enzyme is often considered a molecular target for the development of novel high efficient drugs against prostate cancer. In the present work, the random forest algorithm was used to conduct a QSAR study on 370 CYP17A1 ligands with different structures that were collected from the literature and databases, and a QSAR model was created based on the five important descriptors screened out – 2D adjacency and distance matrix descriptors, 2D atom counts and bond co

In treating atherosclerosis and dyslipidemia, peroxisome proliferator-activated receptor alpha (PPARα) has been recognized as an interesting drug target. It is a ligand-activated transcriptional factor that controls genes involved in lipid metabolism regulation. The discovery of natural PPARα agonists may open new perspectives in its targeting. For several terpenoid molecules, it has been shown that they potentially activate PPARα. Linalool is a terpenoide molecule for which the PPARα antagonistic effect has been demonstrated in vivo. Here, we focused on searching for new terpenoid PPARα agoni

Abstract Recently, there has been an increasing interest in measuring the interaction forces between cell adhesion receptors and their ligands [1–3]. These molecules are either anchored on the membrane of a cell or coated on the surface of a substratum. The two surfaces are joined together as a result of the formation of non-covalent bonds between the receptors and ligands. The forces are measured when the two surfaces are separated. In a theoretical paper published nineteen years ago, George Bell estimated the force required to break a receptor-ligand bond and that required to uproot the rece

Pancreatic ductal adenocarcinoma (PDAC) represents one of the most aggressive cancers, with a 5-year survival rate of only 8%. The progression of the disease is significantly influenced by the tumor microenvironment, especially by cell-extracellular matrix (ECM) interactions. The aim of this study is to repurpose small molecules as inhibitor candidates to jointly target key receptors for the ECM attachment, specifically discoidin domain receptors (DDR1 and DDR2), which are implicated in promoting tumor growth through cell-collagen interactions.Using a computational drug repurposing framework,

Proteins are important macromolecules responsible for a variety of processes in living organisms. One of the most important features of proteins is their ability to respond to environmental stimuli, such as changes in intracellular metal concentration by binding metal ions, which in turns triggers structural changes within the protein that can modify its function or allow the protein to participate in a signaling pathway. One such signaling protein is the so-called neuronal calcium sensor 1 protein or NCS1, which binds Ca2+ along with other abiogenic metals such as Li+, and the metal binding r

In this research, a series of copper complexes containing polypyridyl ligands were designed to study the influence from ligands, nuclearity, solvents and secondary coordination on reactivity toward small-molecule activation. This structure-reactivity relationship was used in investigation for oxygen reduction reactions (ORR), and applied in detection of ascorbic acid (AsH₂). Firstly, copper (II) complexes containing polypyridyl derivatives ligands (i.e., Cu(dpa), Cu(adpa) and Cu₂ (addpa)) were synthesized and fully characterized by elemental analysis, mass spectrometry and X-ray crystallograph

Chemical signaling between beneficial or pathogenic bacteria and plants is a central factor in determining the outcome of plant-microbe interactions. Pectobacterium and Dickeya (soft rot Erwinias) are the major cause of soft rot, stem rot, and blackleg formed on potato and ornamentals, currently with no effective control. Our major aim was to establish and study specific bacterial genes/proteins as targets for anti-virulence compounds, by combining drug design tools and bioinformatics with experimental work. The approach allowed us to identify and test compounds (small molecules) that specific
