Herein, we report a new synthetic route from (S)-pyroglutaminol to (+)-lactacystin, a potent inhibitor of the 20S proteasome. The photoinduced intermolecular C(sp(3))-H alkynylation and intramolecular C(sp(3))-H acylation chemo- and stereoselectively constructed the tetra- and trisubstituted carbon centers, respectively. The obtained...

Autophagy functions as a survival mechanism during cellular stress and contributes to resistance against anticancer agents. The selective antitumor and antimetastatic chelator di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT) causes lysosomal membrane permeabilization and cell death. Considering the integral role of lysosomes in autophagy...

Podocytes play an important role in the pathogenesis and progression of glomerulosclerosis. Recent studies indicate that aldosterone/mineralocorticoid receptor (MR) is a major contributor of chronic kidney disease (CKD) progression. Aldosterone/MR induces glomerular podocyte injury, causing the disruption of the glomerular...
