Identification of 2-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)amino)-N-phenylpropanamides as a novel class of potent DprE1 inhibitors
摘要:
The identification of a novel series of DprE1 inhibitors based on a 2((2,3-dihydrobenzo [b][1,4]dioxin-6-yl) amino)-N-phenylpropanamide scaffold is described herein. SAR exploration around the HTS hit 1 led to the identification of multiple analogues with potent DprE1 inhibition and good whole-cell antimycobacterial activity.

A series of chiral pyridazin-3(2H)-ones was synthesized, separated as pure enantiomers, and evaluated for N-formyl peptide receptor (FPR) agonist activity. Characterization of the purified enantiomers using combined chiral HPLC and chiroptical studies (circular dichroism, allowed unambiguous assignment of the absoluteconfiguration for each pair of enantiomers). Evaluation of the ability of racemic

Playing domino: Cu-catalyzed radical/iminiumdominostrategy (RIDS) for the efficient synthesis of quaternary-carbon-containing γ-lactam-based multiheterocyclic structures. This strategy enables the efficient syntheses of highly congested γ-lactam-based multiheterocyclic structures possessing quaternary carbons.
There are several reports of lactam cyclizations, but most yield less-substituted lactam rings. Therefore, diastereoselective cyclization to yield highly substituted lactams is one of the challenges in this field. We therefore propose a strategy involving the reactions of α-halocarboxamides with E/Z-mixed internal olefins here. An Fe/triphos catalyst system is effective in reactions between α-bromocarboxamides
