Discovery of IRAK1/4/pan-FLT3 Kinase Inhibitors as Treatments for Acute Myeloid Leukemia.

We report the discovery of an imidazopyridine series of IRAK1/4/pan-FLT3 kinase inhibitors. Optimization of this series has produced compound which displays potent and selective inhibition of IRAK1, IRAK4, FLT3, and all mutant forms of FLT3, as well as good in vitro ADME and pharmacokinetic properties. In a mouse xenograft model of AML, produces survival prolongation equal to that of Gilteritinib, the leading marketed FLT3 inhibitor currently used to treat AML.

Metagenomic time series reveals a Western English Channel viral community dominated by members with strong seasonal signals.

Marine viruses are key players of ocean biogeochemistry, profoundly influencing microbial community ecology and evolution. Despite their importance, few studies have explored continuous inter-seasonal viral metagenomic time series in marine environments. Viral dynamics are complex, influenced by multiple factors such as host population dynamics and environmental conditions.

In field use of water samples for genomic surveillance of infectious spleen and kidney necrosis virus (ISKNV) infecting tilapia fish in Lake Volta, Ghana.

Viral outbreaks are a constant threat to aquaculture, limiting production for better global food security. A lack of diagnostic testing and monitoring in resource-limited areas hinders the capacity to respond rapidly to disease outbreaks and to prevent viral pathogens becoming endemic in fisheries productive waters. Recent developments in diagnostic testing for emerging viruses, however, offers a solution for rapid monitoring of viral outbreaks.

Recurring seasonality exposes dominant species and niche partitioning strategies of open ocean picoeukaryotic algae.

Ocean spring phytoplankton blooms are dynamic periods important to global primary production. We document vertical patterns of a diverse suite of eukaryotic algae, the prasinophytes, in the North Atlantic Subtropical Gyre with monthly sampling over four years at the Bermuda Atlantic Time-series Study site. Water column structure was used to delineate seasonal stability periods more ecologically relevant than seasons defined by calendar dates.
