A new approach methodology to identify tumorigenic chemicals using short-term exposures and transcript profiling

Frontiers in Toxicology
Current methods for cancer risk assessment are resource-intensive and not feasible for most of the thousands of untested chemicals. In earlier studies, we developed a new approach methodology (NAM) to identify liver tumorigens using gene expression ...

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 ...

Probing the Inhibitory Potential of Halogenated Symmetrical Formamidine Against MAO‐A and MAO‐B: Structural Elucidation, Molecular Dynamic Simulation and DFT Computational Studies

Chemistry &Biodiversity, EarlyView.
ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...
