Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

Aggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.

hERG Blockade by Iboga Alkaloids

Cardiovascular Toxicology, 2015
The iboga alkaloids are a class of naturally occurring and synthetic compounds, some of which modify drug self-administration and withdrawal in humans and preclinical models. Ibogaine, the prototypic iboga alkaloid that is utilized clinically to treat addictions, has been associated with QT prolongation, torsades de pointes and fatalities.

Position of Premature Termination Codons Determines Susceptibility of hERG Mutations to Nonsense-Mediated mRNA Decay in Long QT Syndrome

, 2014
The degradation of human ether-a-go-go-related gene (hERG, KCNH2) transcripts containing premature termination codon (PTC)mutations by nonsense-mediatedmRNA decay (NMD) is an importantmechanismof long QT syndrome type 2 (LQT2).

Two Types of K⁺ Channel Subunit, Erg1 and KCNQ2/3, Contribute to the M-Like Current in a Mammalian Neuronal Cell [PDF]

, 1999
The potassium M current was originally identified in sympathetic ganglion cells, and analogous currents have been reported in some central neurons and also in some neural cell lines.

Pharmacokinetic Prediction and Cytotoxicity of New Quercetin Derivatives

Chemistry &Biodiversity, EarlyView.
ABSTRACT Quercetin (QUE) possesses various pharmacological properties; however, its low bioavailability and solubility hinder its beneficial effects. Enzymatic glycosylation has been explored to improve these aspects. In the present study, we used a sucrose phosphorylase variant to catalyze the regioselective transglucosylation of QUE, predicted the ...

Flavonoid Profile, Biological Potentials, and In Silico Approaches of Methanol Extracts on AChE: Amaranthus retroflexus L.

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study investigated the flavonoid compounds and their biological activities in methanol extracts obtained from root, stem, leaf, and flower parts of Amaranthus retroflexus L. Flavonoids in the extracts were characterized for the first time by liquid chromatography–highresolution mass spectrometry (LC–HRMS), and a total of eight flavonoid ...

Antiprotozoal Activity of Highly Substituted Pyrazole and Pyrimidine Derivatives

ChemMedChem, EarlyView.
Based on previously identified antimalarial agents, a series of highly substituted pyrazole and pyrimidines derivatives has been synthesized and tested for antiplasmodial and antileishmanial activity. Selected derivatives show promising antiplasmodial effect with a predicted favorable pharmacokinetic profile.

Disease-associated mutations in KCNE potassium channel subunits (MiRPs) reveal promiscuous disruption of multiple currents and conservation of mechanism. [PDF]

, 2002
KCNE genes encode single transmembrane-domain subunits, the MinK-related peptides (MiRPs), which assemble with pore-forming alpha subunits to establish the attributes of potassium channels in vivo.
