Gao, Kai published the artcileNanoscale, automated, high throughput synthesis and screening for the accelerated discovery of protein modifiers, SDS of cas: 86-51-1, the main research area is protein modifier preparation combinatorial nanoscale; cyclic aromatic amidine aldehyde isocyanide Groebke Blackburn Bienayme reaction.

Hit finding in early drug discovery is often based on high throughput screening (HTS) of existing and historical compound libraries, which can limit chem. diversity, is time-consuming, very costly, and environmentally not sustainable. On-the-fly compound synthesis and in situ screening in a highly miniaturized and automated format has the potential to greatly reduce the medicinal chem. environmental footprint. Here, acoustic dispensing technol. has been used to synthesize a library in a 1536 well format based on the Groebke-Blackburn-Bienayme’ reaction (GBB-3CR) on a nanomole scale. The unpurified library was screened by differential scanning fluorimetry (DSF) and cross-validated using microscale thermophoresis (MST) against the oncogenic protein-protein interaction menin-MLL. Several GBB reaction products were found as μM menin binder, and the structural basis of the interactions with menin was elucidated by co-crystal structure anal. Miniaturization and automation of the organic synthesis and screening process can lead to an acceleration in the early drug discovery process, which is an alternative to classical HTS and a step towards the paradigm of continuous manufacturing
