QH536
QH536 is a degrader of HMG-CoA reductase (HMGCR) with an EC50 of 0.22 μM. QH536 induces ubiquitination and degradation of HMGCR via the ubiquitin-proteasome pathway, inhibits cholesterol biosynthesis, reduces cholesterol levels, suppresses hepatic stellate cell proliferation, and decreases the expression of fibrotic and inflammatory genes/proteins without inducing intracellular cholesterol accumulation. QH536 can be used in the research of cardiovascular diseases and non-alcoholic steatohepatitis (NASH).

HMGCR 0.22 μM (EC50) |
In Vitro
QH536 (compound 29) (16 h) potently promotes HMGCR degradation in CHO-7/HMGCRTM1-8-GFP cells with an EC50 of 0.22 μM[1].
QH536 (10 μM; 16 h) does not induce cholesterol accumulation in SV589 human fibroblast cells[1].
QH536 (0.1-10 μM; 16 h) reverses Lovastatin (HY-N0504)-induced HMGCR accumulation and degrades endogenous HMGCR in CHO-K1 cells with an EC50 of 0.13 μM[1].
QH536 (1-10 μM; 4-8 h) degrades HMGCR in CHO-K1 cells via the ubiquitin-proteasome pathway, requiring functional ubiquitination sites on HMGCR[1].
QH536 (0.3-10 μM; 7 days) inhibits cholesterol biosynthesis in CHO-7 cells, leading to growth inhibition that is reversed by exogenous cholesterol[1].
QH536 (0.1-2 μM; 24 h) dose-dependently reduces TGFβ1-induced fibrotic gene (α-SMA, COL1A1, TIMP1, TGFβ1) and protein (α-SMA) expression in LX-2 hepatic stellate cells, with no effect on quiescent cells[1].
QH536 (0.1-2 μM; 24 h) dose-dependently lowers TGFβ1-induced cholesterol levels and suppresses TGFβ1-induced proliferation in LX-2 hepatic stellate cells, with no effect on quiescent cells[1].
QH536 (0.1-2 μM; 24 h) dose-dependently lowers LPS-induced cholesterol levels and suppresses LPS-induced inflammatory gene (TNF-α, IL-6, IL-1β) expression in RAW264.7 murine macrophage cells, with no effect on quiescent cells[1].

Cell Line:CHO-K1 cells
-
Concentration:0.1-10 μM (with lovastatin); concentration gradient (sterol-depleted medium)
-
Incubation Time:16 h
-
Result:Eliminated lovastatin-induced HMGCR accumulation, reducing from 15.2-fold increase to 0.4-fold relative to vehicle in a dose-dependent manner.
Degraded endogenous HMGCR with an EC50 of 0.13 μM.
-
Cell Line:CHO-K1 cells
-
Concentration:1-10 μM (8 h with/without MG-132); 1-10 μM (4 h with mevalonate and MG-132); 1-10 μM (transfected cells)
-
Incubation Time:8 h (with/without MG-132); 4 h (with mevalonate and MG-132)
-
Result:Had its induced HMGCR degradation completely blocked by the proteasome inhibitor MG-132.
Triggered HMGCR ubiquitination in a dose-dependent manner.
Had its degradation effect completely blocked when HMGCR ubiquitination sites (lysine 89 and 248) were mutated to arginine.
-
Cell Line:LX-2 hepatic stellate cells
-
Concentration:0.1 μM; 0.2 μM; 0.5 μM; 1 μM; 2 μM
-
Incubation Time:24 h
-
Result:Significantly inhibited TGFβ1-induced cholesterol levels and cell proliferation in a dose-dependent manner.
Had no effect on quiescent LX-2 cells (without TGFβ1 stimulation).
