Assessment of the physicochemical properties and stability for pharmaco-kinetic prediction of pyrazinoic acid derivatives
(2020-01-01)
Background: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis, which still has high prevalence worldwide. In addition, cases of drug resistance are frequently observed. In the search for new ...
Metabolic stability of glyphosate and its environmental metabolite (aminomethylphosphonic acid) in the ruminal content of cattle
(Taylor & Francis Ltd, 2022-03)
Glyphosate (GLY) is one of the most commonly used herbicides worldwide. Both GLY and aminomethylphosphonic acid (AMPA), its main degradation product, may be present in feedstuffs offered to dairy cows. Although the major ...
Design of stable large-scale metabolic networks
(Elsevier Science, 2009-08)
In this work we propose an eigenvalue optimization approach to ensure steady state stability of the Embden-Meyerhof-Parnas pathway, the pentose-phosphate pathway and the phosphotransferase system of Escherichia coli. The ...
Cholesterol metabolism: Increasingly complex El metabolismo del colesterol: Cada vez más complejo
(2012)
Cholesterol is an important molecule; it is necessary for the biosynthesis of steroidal hormones, bile salts and to maintain the stability of biological membranes in animal cells. However, its excess is negative and is ...
New insights into the regulatory mechanisms of ppGpp and DksA on Escherichia coli RNA polymerase-promoter complex
(Oxford University Press, 2015)
The stringent response modulators, guanosine tetraphosphate (ppGpp) and protein DksA, bind RNA polymerase (RNAP) and regulate gene expression to adapt bacteria to different environmental conditions. Here, we use Atomic ...
RNA-Binding Proteins in Trichomonas vaginalis: Atypical Multifunctional Proteins
(MDPI, 2015)
Iron homeostasis is highly regulated in vertebrates through a regulatory system mediated by RNA-protein interactions between the iron regulatory proteins (IRPs) that interact with an iron responsive element (IRE) located ...
Design of stable metabolic networks
(Wiley VCH Verlag, 2017-08)
In this work, we propose eigenvalue optimization combined with Lyapunov theory concepts to ensure stability of the Embden—Meyerhof–Parnas pathway, the pentosephosphate pathway, the phosphotransferase system and fermentation ...
Hepatic biotransformation pathways and ruminal metabolic stability of the novel anthelmintic monepantel in sheep and cattle
(Wiley Blackwell Publishing, Inc, 2016-02)
Monepantel (MNP) is a new amino-acetonitrile derivative anthelmintic drug used for the treatment of gastrointestinal (GI) nematodes in sheep. The present work investigated the main enzymatic pathways involved in the hepatic ...
Microbial communities in petroleum-contaminated sites: Structure and metabolisms
(2022-01-01)
Over recent decades, hydrocarbon concentrations have been augmented in soil and water, mainly derived from accidents or operations that input crude oil and petroleum into the environment. Different techniques for remediation ...
