Discovery of 6-ethyl-2,4-diaminopyrimidine-based small molecule renin inhibitors
摘要:
Novel 2,4-diaminopyrimidine-based small molecule renin inhibitors are disclosed. Through high throughput screening, parallel synthesis, X-ray crystallography, and structure based drug design, we have developed the first non-chiral, non-peptidic, small molecular template to possess moderate potency against renin. The designed compounds consist of a novel 6-ethyl-5(1,2,3,4-tetrahydroquinolin-7-yl)pyrimidine-2,4-diamine ring system that exhibit moderate potency (IC50: 91-650 nM) against renin while remaining 'Rule-of-five' compliant.

A highly potent, bimodal activity-based probe for the therapeutically relevant cysteineproteaserhodesain was developed. We utilized two different access points at the coumarin fluorophore for incorporation of the rhodesain inhibitor part and the biotin affinity label. The two reporter tags were employed for on-blot chemiluminescence detection and affinity purification as well as post-labeling quantification

A series of twelve fluorescently labeled amino acids were designed by assembling different coumarin, fluorescein, or nitrobenzofurazan fluorophores with N-protected lysine or 2-aminopropionic acid. The synthesized amino acids were evaluated with regard to their spectroscopic properties. The easy introduction of the amino acids into peptides and peptidomimetics was exemplarily shown for one coumarin-labeled amino acid.
