Transcriptional control of cardiac fibroblast plasticity

Cardiac fibroblasts help maintain the normal architecture of the healthy heart and are responsible for scar formation and the healing response to pathological insults. Various genetic, biomechanical, or humoral factors stimulate fibroblasts to become contractile smooth muscle-like cells called myofibroblasts that secrete large amounts of extracellular matrix. Unfortunately, unchecked myofibroblast activation in heart disease leads to pathological fibrosis, which is a major risk factor for the development of cardiac arrhythmias and heart failure. A better understanding of the molecular mechanisms that control fibroblast plasticity and myofibroblast activation is essential to develop novel strategies to specifically target pathological cardiac fibrosis without disrupting the adaptive healing response. This review highlights the major transcriptional mediators of fibroblast origin and function in development and disease. The contribution of the fetal epicardial gene program will be discussed in the context of fibroblast origin in development and following injury, primarily focusing on Tcf21 and C/EBP. We will also highlight the major transcriptional regulatory axes that control fibroblast plasticity in the adult heart, including transforming growth factor beta (TGFbeta)/Smad signaling, the Rho/myocardin-related transcription factor (MRTF)/serum response factor (SRF) axis, and Calcineurin/transient receptor potential channel (TRP)/nuclear factor of activated T-Cell (NFAT) signaling. Finally, we will discuss recent strategies to divert the fibroblast transcriptional program in an effort to promote cardiomyocyte regeneration. This article is a part of a Special Issue entitled “Fibrosis and Myocardial Remodeling”.

Mineralization pathways and kinetics of degradation of emerging contaminants as mixtures using UV/H2O2

The removal of pharmaceuticals and other substances of emerging concern is a major issue in water and wastewater treatment that is garnering increased attention internationally. As commonly employed modules in water treatment do not sufficiently remove these compounds, a need exists for new technologies that can effectively treat them. In this work, an evaluation of the advanced oxidation process UV/H2O2 is presented for the degradation of four pharmaceuticals from water: venlafaxine (VEN), carbamazepine (CBZ), fluoxetine (FLU) and sulfamethoxazole (SFX). Experimental results showed that all compounds could be successfully degraded to below detection limits following pseudo first order kinetics. SFX degraded significantly faster than the other compounds, with the other three degrading at very similar rates. Diminishing returns on increases in degradation rate were seen as H2O2 dosage was increased above 100 mg/L, indicating that higher levels of H2O2 dosing are unlikely to be cost effective. Comparison between compounds treated in a mixture compared to individually demonstrated only a minor decrease in reaction rate of 81-83%. Detailed study on the degradation pathway for each compound elucidated details on potential intermediate breakdown products. While the expected hydroxylation of aromatic structures was seen for all compounds, several other mechanisms were displayed that were compound specific. No notable breakdown products were detected after treatment period of 10 min for all the pharmaceuticals tested.

Ab initio analysis on metal ion catalysis in the enolization reactions of some acetylheterocycles: Kinetics of the enolization reactions of 3-acetyl-5-methylisoxazole, 5-acetyl-3-methylisoxazole and 3(5)-acetylpyrazole

Kinetic data on the enolization reaction of 3-acetyl-5-methylisoxazole, 5-acetyl-3-methylisoxazole, 3(5)-acetylpyrazole and some previously studied acetylheterocycles have been the object of a comprehensive ab initio analysis. Enolization rate constants were measured spectrophotometrically by the halogen trapping technique at 25 C and ionic strength of 0.3 mol dm-3 in water, in acetate buffers, in dilute hydrochloric acid, in dilute sodium hydroxide and in the presence of some metal ion salts. In the spontaneous (water) and base (acetate) catalysed reactions the ketones investigated are generally more reactive than acetophenone, according to the electron-withdrawing effect of the heterocyclic ring compared with the benzene ring. In particular, acetylisoxazoles, 3(5)-acetylpyrazole and acetylthiazoles are more reactive than acetylfurans, 2-acetylpyrrole and acetylthiophenes respectively, and this can be attributed to the additional effect of the second heteroatom in the heterocyclic moiety. On the other hand, the compounds investigated are generally less reactive than acetophenone in the H3O+ -catalysed reaction. Ab initio calculations on the relative stability of the protonated and unprotonated forms of the substrates investigated have been compared with the kinetic results obtained in acid solutions. As far as the metal ion catalysis is concerned, an approach in terms of DeltaDeltaE can give an estimate of the combined contributions of charge densities and frontier orbitals to the interaction of the substrate with the metal ion catalyst. A comparison of experimental metal activating factor values and ab initio calculations outlines the importance of charge density on the carbonyl oxygen atom of acetylheterocycles with one heteroatom. An analogous comparison for acetylheterocycles with two heteroatoms suggests the formation of a chelate complex or transition state, in which the metal ion coordinates both the carbonyl oxygen and the aza nitrogen, whenever these two atoms are suitably placed within the molecular structure of the acetylheterocycle.

Indolo[3,2-c]quinoline G-quadruplex stabilizers: A structural analysis of binding to the human telomeric G-quadruplex

A library of 5-methylindolo[3,2-c]quinolones (IQc) with various substitution patterns of alkyldiamine side chains were evaluated for G-quadruplex (G4) binding mode and efficiency. Fluorescence resonance energy transfer melting assays showed that IQcs with a positive charge in the heteroaromatic nucleus and two weakly basic side chains are potent and selective human telomeric (HT) and gene promoter G4 stabilizers. Spectroscopic studies with HT G4 as a model showed that an IQc stabilizing complex involves the binding of two IQc molecules (2,9-bis{[3-(diethylamino)propyl]amino}-5-methyl-11H-indolo[3,2-c]quinolin-5-ium chloride, 3 d) per G4 unit, in two non-independent but equivalent binding sites. Molecular dynamics studies suggest that end-stacking of 3 d induces a conformational rearrangement in the G4 structure, driving the binding of a second 3 d ligand to a G4 groove. Modeling studies also suggest that 3 d, with two three-carbon side chains, has the appropriate geometry to participate in direct or water-mediated hydrogen bonding to the phosphate backbone and/or G4 loops, assisted by the terminal nitrogen atoms of the side chains. Additionally, antiproliferative studies showed that IQc compounds 2 d (2-{[3-(diethylamino)propyl]amino}-5-methyl-11H-indolo[3,2-c]quinolin-5-ium chloride) and 3 d are 7- to 12-fold more selective for human malignant cell lines than for nonmalignant fibroblasts.

Novel conformationally constrained analogues of agomelatine as new melatoninergic ligands

Novel conformationally restricted analogues of agomelatine were synthesized and pharmacologically evaluated at MT1 and MT2 melatoninergic receptors. Replacement of the N-Acetyl side chain of agomelatine by oxathiadiazole-2-oxide (compound 3), oxadiazole-5(4H)-one (compound 4), tetrazole (compound 5), oxazolidinone (compound 7a), pyrrolidinone (compound 7b), imidazolidinedione (compound 12), thiazole (compounds 13 and 14) and isoxazole moieties (compound 15) led to a decrease of the melatoninergic binding affinities, particularly at MT1. Compounds 7a and 7b exhibiting nanomolar affinity towards the MT2 receptors subtypes have shown the most interesting pharmacological results of this series with the appearance of a weak MT2-selectivity.

Recent highlights on molecular hybrids potentially useful in central nervous system disorders

Molecular hybridization is a recent strategy based on the covalent fusion of two or more pharmacophores to create a single molecule with multiple mechanisms of action, which represents an encouraging approach in the development of new drugs with potential therapeutic application in several pathologies. This review provides a comprehensive perspective of the most relevant advances in the development of hybrid molecules acting in the central nervous system. For instance, several opioid hybrids based on endogenous opioid peptides (e.g. enkephalins, deltorphins and endomorphins) have been developed, and gamma-aminobutyric acid agonists have also been designed for neuropathic pain control. In addition, a number of hybrid compounds have also been synthesized and evaluated for their anticonvulsant activity and neurotoxicity, which may be further developed as potential antiepileptic drugs. Moreover, several hybrid compounds have also been designed for the treatment of neurodegenerative diseases focusing primarily on Alzheimer?s disease by targeting the cholinergic neurotransmission, as acetylcholinesterase inhibitors, and the amyloid beta-protein deposition. There are also studies addressing hybrid compounds including an antioxidant moiety, which can be potentially useful in Alzheimer?s and Parkinson?s diseases and other neurodegenerative disorders. Additionally, other research works have also shown promising hybrid molecules for depression, autism and cocaine addiction. Thus, the development of molecular hybrid compounds seems to be a promising strategy in the discovery of novel therapeutic drugs.
