Recent developments in the chemistry and enzyme inhibitory activity of fused thiazoles and thiadiazoles

Vietnam Journal of Chemistry, EarlyView.
Abstract The combination of cyclization reactions of thiadiazoles and benzothiazoles with Pd‐catalyzed cross‐coupling reactions provided a convenient synthesis of annulated, fluorinated and non‐fluorinated heterocycles, such as 1,3,4‐thiadiazolo[3,2‐a]pyrimidin‐5‐ones, benzothiazolo[3,2‐a]pyridimidin‐4‐ones, benzothiazolo[2,3‐b]quinazolin‐12‐ones and ...

Quantifying Soil Microbiome Abundance by Metatranscriptomics and Complementary Molecular Techniques—Cross‐Validation and Perspectives

Molecular Ecology Resources, EarlyView.
ABSTRACT Linking meta‐omics and biogeochemistry approaches in soils has remained challenging. This study evaluates the use of an internal RNA extraction standard and its potential for making quantitative estimates of a given microbial community size (biomass) in soil metatranscriptomics. We evaluate commonly used laboratory protocols for RNA processing,

gmmDenoise: A New Method and R Package for High‐Confidence Sequence Variant Filtering in Environmental DNA Amplicon Analysis

Molecular Ecology Resources, EarlyView.
ABSTRACT Assessing and monitoring genetic diversity is vital for understanding the ecology and evolution of natural populations but is often challenging in animal and plant species due to technically and physically demanding tissue sampling. Although environmental DNA (eDNA) metabarcoding is a promising alternative to the traditional population genetic
