BDM44768
BDM44768 is an insulin-degrading enzyme (IDE) inhibitor (human IC50 = 0.06 μM; Ki = 60 nM). BDM44768 impairs D-Glucose (HY-B0389) tolerance, enhances Insulin (HY-P0035) signaling, and increases Amyloid-β concentration in an IDE-dependent manner by chelating the catalytic zinc, stabilizing the closed conformation, and binding the substrate/catalytic cleft. BDM44768 can be used in research on diabetes and metabolic dysfunction-associated steatotic liver disease (MASLD).

hIDE 0.06 μM (IC50) |
IDE 60 nM (Ki) |
In Vitro
BDM44768 (15 μM; overnight for mRNA detection, 24 h for protein detection) enhances TN- or palmitate-induced IRE1 pathway activation in HepG2 cells, increasing XBP1s, ERDJ4, and p-IRE1α, while alone it does not activate the UPR[4].
BDM44768 (1.25 μM; 30 min) reversibly inhibits hIDE, and activity is restored after 100-fold dilution[6].
BDM44768 (30 mM; 2 h) binds to IDE in HepG2 cells with a ΔT_agg of 6.4 °C and a cell/medium ratio of 0.11[6].
BDM44768 (1-10 µM; 1 h) shows good Caco-2 cell membrane permeability at 1 and 10 µM[1].
BDM44768 (6.25-50 mM) binds hIDE in solution, and its interaction is stronger than that of the 1,5 isomer[1].
BDM44768 (20 mM) induces the transition of hIDE from an open conformation to a closed conformation in solution[1].
BDM44768 (200 mM) binds the hIDE catalytic site and locks hIDE in a closed inhibitory conformation[1].

Cell Line:Differentiated human SH-SY5Y neuroblastoma cells
-
Concentration:10 mM; 30 mM
-
Incubation Time:48 h
-
Result:Revealed significantly increased concentrations of Aβ1-40 in culture supernatants of cells incubated with BDM44768, but not with 10, a 100-fold less active analogue.
-
Cell Line:HepG2 human hepatocellular carcinoma cells
-
Concentration:15 μM
-
Incubation Time:overnight (mRNA); 24 h (protein)
-
Result:Had no impact on UPR markers in unstressed cells.
Potentiated the effect of TN on the IRE1α pathway, specifically XBP1s, and phosphorylated and total IRE1α proteins.
The combination of BDM44768 with palmitate potentiated expression of IRE1 pathway-related genes XBP1s and ERDJ4 and increased phosphorylated IRE1α protein.
Failed to increase XBP1s and Erdj4 expression in IDE-silenced HepG2 cells stressed with TN.
Other UPR-related pathways were not impacted.

In Vivo
BDM44768 (50 mg/kg; intraperitoneal injection; single administration; 15 min before oral glucose) does not impair glucose tolerance in C57BL/6J IDE−/− mice, indicating that this glucose intolerance effect depends on IDE[1].
BDM44768 (50 mg/kg; intraperitoneal injection; single administration; 15 min before oral glucose) acutely impairs glucose tolerance and increases insulinemia in NOD wild-type mice[1].
BDM44768 (50 mg/kg; intraperitoneal injection; single administration; 15 min before oral glucose) does not impair glucose tolerance in NOD IDE−/− mice, consistent with an IDE-dependent effect[1].

Animal Model:C57BL/6J wild-type (male 12-week-old for ITT and PTT; male or female 11-16-week-old for OGTT/IPGTT)[1]
-
Dosage:50 mg/kg
-
Administration:i.p.; single administration; 15 min before challenge

Result:In the ITT, BDM44768 slightly increased serum insulin concentrations, with an effect at 30 min, and increased phosphorylation of liver and muscle insulin receptor, Akt, and ERK; it tended to enhance the glucose-lowering effect of insulin at 30 and 60 min.
In the OGTT, BDM44768 increased plasma glucose concentrations from 15 to 90 min after oral glucose load, and the AUC of glycaemia as a function of time was increased; plasma insulin levels at baseline, 15, and 90 min after glucose load were similar to vehicle.
In the IPGTT, BDM44768 increased plasma glucose concentrations at all time points after i.p. glucose.
In the PTT, glucose excursion curves and AUC were similar to vehicle.

Animal Model:C57BL/6J IDE−/− (male or female, 11-16 weeks)[1]
-
Dosage:50 mg/kg
-
Administration:i.p.; single administration; 15 min before oral glucose

Dosage:50 mg/kg
-
Administration:i.p.; single administration; 15 min before oral glucose
-
Result:produced a strong impairment of glucose tolerance in WT NOD mice.
Plasma insulin levels were elevated at 15, 90, and 180 min compared with WT; the hyperinsulinemia induced by BDM44768 in WT NOD mice was similar to the hyperinsulinemia in IDE−/− NOD mice given vehicle or BDM44768.

-
Dosage:50 mg/kg
-
Administration:i.p.; single administration; 15 min before oral glucose

Plasma insulin in NOD IDE−/− mice given BDM44768 was comparable to NOD IDE−/− mice given vehicle and to WT NOD mice given BDM44768.

Animal Model:C57BL/6J (wild-type, 20-week-old)[4]
-
Dosage:50 mg/kg
-
Administration:i.p.; two administrations; 8 h and 2 h before sacrifice
-
Result:In tunicamycin-injected mice, BDM44768 significantly potentiated TN-induced hepatic Xbp1s and Erdj4 mRNA expression and increased hepatic IRE1α phosphorylation.
Also stimulated PERK-related genes (Atf4, Gadd34, and Chop) in TN + BDM44768-treated mice compared with TN-injected mice.
Mice treated with TN + BDM44768 showed further increased hepatic triglyceride accumulation, higher neutral lipid staining by Oil Red O, and an increased number of lipid droplets by electron microscopy compared with TN-injected mice.
Consistently, BDM44768 in acute ER stress conditions increased the expression of FA import (Cd36), LD formation (Adrp, Fitm1) and LD fusion (Fsp27) genes compared with TN-stimulated mice.
In TN-treated mice, BDM44768 increased hormone-sensitive lipase (HsL) phosphorylation in adipose tissue.
CD36 protein was higher in the liver from BDM44768 + TN-treated compared with TN alone-treated mice.
