(4-[6-(4-isopropoxyphenyl)pyrazolo [1,5-a]pyrimidin-3-yl] quinoline) is a novel inhibitor of autophagy.

ABSTRACT:

Background and purpose

Autophagy is an important intracellular degradation system, which is related to various diseases. In preliminary experiments we found that D4-[6-(4-isopropoxyphenyl)pyrazolo [1,5-a]pyrimidin-3-yl] quinoline (DMH1) inhibited autophagy responses. However DMH1 also inhibits the signalling pathway activated by bone morphogenetic protein-4 (BMP4). The aim of the present study was to elucidate the inhibitory effects of DMH1 on autophagy and the underlying mechanisms.

Experimental approach

The effects of DMH1 on autophagy responses were evaluated in cultures of different cell types and with different stimuli to induce autophagy, using Western blots, transmission electron microscopy and fluorescent microscopy.

Key results

DMH1 inhibited starvation-induc
