O-salicylaldehyde has been utilized for the N-term ser/thr selective ligation in organic condition, and we explored this chemistry in aqueous condition that led to discovery of N-term cys selectivity. (link)
Image-based host cell infection profiling using fluorescence superoxide probe perfectly discriminates 3 AI subtypes (H1N1, H5N9, H9N2). (link)
Live cell imaging of chloro-functionalized photo-affinity BODIPY probe reveals sub-cellular accumulations. This article was selected as cover feature. (link)
Cellular binding target of dansyl fluorophore containing vinylsulfone group was identified as 3-Phosphoglycerate dehydrogenase (PHGDH), a key enzyme in the biosynthesis of serine. (link)
Aggregation property of organic fluorophore can be a key for biomolecule sensing. We demonstrated bulk aggregation based fluorescence turn-on sensor for progesterone using Dansyl scaffold. It was selected as Hot Paper from Angew. Chem. (link)
Comprehensive evaluation of bio-orthogonal photo-crosslinker for bio-active small molecule was studied (BRD4 inhibitor case study). (link)
First 48 membered dansyl library (DS) synthesis and their photo-physical properties were reported. (link)
The first photo-affinity BODIPY scaffold was published in Chem. Comm. (link)
Transcriptome expression assisted non-directed proteomic profiling (TEAnDPP) strategy demonstrated identification of host cell response factors. (link)
Unbiased fluorophore tagging together with competitive chemical proteomic profiling reveals host cell cycle regulator from Salmonella. (link)
