An analysis of chemical reactions used in current medicinal chemistry (2014), three decades ago (1984), and natural product total synthesis has been conducted. The revealed that the most frequently synthetic reactions, none were discovered within past 20 years only two 1980s 1990s (Suzuki-Miyaura Buchwald-Hartwig). This suggests an inherent high bar impact for new drug discovery. amide bond formation, Suzuki-Miyaura coupling, SNAr likely due to commercial availability reagents,...

To better understand the difficulties surrounding identification of novel antibacterial compounds from corporate screening collections, physical properties ∼3200 project with whole cell activity against Gram-negative or Gram-positive pathogens were profiled and compared to actives found high throughput (HTS) screens conducted on both biochemical phenotypic bacterial targets. The output 23 HTS illustrated that when compounds, significantly more hydrophobic than (typically 2-4 log units...

Abstract Tauopathies are neurodegenerative diseases associated with accumulation of abnormal tau protein in the brain. Patient iPSC-derived neuronal cell models replicate disease-relevant phenotypes ex vivo that can be pharmacologically targeted for drug discovery. Here, we explored autophagy as a mechanism to reduce burden human neurons and, from small-molecule screen, identify mTOR inhibitors OSI-027, AZD2014 and AZD8055. These compounds more potent than rapamycin, robustly downregulate...

A high-throughput phenotypic screen based on a Citrobacter freundii AmpC reporter expressed in Escherichia coli was executed to discover novel inhibitors of bacterial cell wall synthesis, an attractive, well-validated target for antibiotic intervention. Here we describe the discovery and characterization sulfonyl piperazine pyrazole compounds, each with mechanisms action. E. mutants resistant these compounds display no cross-resistance antibiotics other classes. Resistance maps LpxH, which...

Demonstration of target binding is a key requirement for understanding the mode action new therapeutics. The cellular thermal shift assay (CETSA) has been introduced as powerful label-free method to assess engagement in physiological environments. Here, we present application live-cell CETSA different classes integral multipass transmembrane proteins using three case studies, first showing large and robust stabilization outer mitochondrial five-pass protein TSPO, second being modest SERCA2,...

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder typically characterized by insoluble inclusions of hyperphosphorylated TDP-43. The mechanisms underlying toxic TDP-43 accumulation are not understood. Persistent activation p38 mitogen-activated protein kinase (MAPK) implicated in ALS. However, it unclear how MAPK affects proteinopathy. Here, we show that p38α inhibition reduces pathological phosphorylation, aggregation, cytoplasmic mislocalization, and...

We report here an unexpectedly strong preference toward para substitution in phenyl rings within drug discovery programs. A population analysis of aromatic various databases demonstrated that is favored over meta and ortho regioisomers, with p-chlorophenyl (p-ClPh) being one the most predominant examples. speculate frequency p-ClPh traced back to historical models medicinal chemistry where para-substituted regioisomers were perhaps more easily accessed, further reinforced by Topliss 1972 if...

The discovery of ligands via affinity-mediated selection DNA-encoded chemical libraries is driven by the quality and concentration protein target. G-protein-coupled receptors (GPCRs) other membrane-bound targets can be difficult to isolate in their functional state at high concentrations, therefore have been challenging for selection. Here, we report a successful campaign against protease-activated receptor 2 (PAR2). Using thermo-stabilized mutant PAR2, conducted affinity using our...
