BMS-823778 is a novel, potent, orally bioavailable and selective inhibitor of 11-β-hydroxysteroid-dehydrogenase 1 (11βHSD-1). BMS-823778 is a potential therapeutic agent for type 2 diabetes mellitus (T2DM).
| Targets |
Human 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD-1) (IC₅₀ = 2.3 nM; Ki = 0.9 nM)[1]
Mouse 11β-HSD-1 (IC₅₀ = 600 nM; Ki = 380 nM)[1] Cynomolgus monkey 11β-HSD-1 (Ki = 7 nM)[1] No inhibition of 11β-HSD-2 up to 30 µM (human) and 20 µM (mouse, rat, monkey)[1] |
|---|---|
| ln Vitro |
BMS-823778 inhibits human 11β-HSD-1 enzyme with an IC₅₀ of 2.3 nM and a Ki of 0.9 nM. It shows >10,000-fold selectivity over 11β-HSD-2. Mouse enzyme activity is weaker (IC₅₀ = 600 nM). Pregnane X receptor (PXR) transactivation is negligible (EC₅₀ > 50 µM). It exhibits excellent aqueous solubility.[1]
Cytochrome P450 inhibition for CYP2C19 is present (IC₅₀ = 1.9 µM for compound 1, a predecessor.[1] |
| ln Vivo |
During diet-induced exercise (DIO), BMS-823778 (10-100 mg/kg; oral; once) hydrochloride shows strong acute pharmacodynamic effects (ED50=34 mg/kg) [1].
In cynomolgus monkeys, BMS-823778 shows robust acute pharmacodynamic effects with an ED₅₀ of 0.6 mg/kg in a dehydrocorticosterone (DHC) challenge assay.[1] In diet-induced obese (DIO) mice, the ED₅₀ is 34 mg/kg in the same DHC challenge assay.[1] In an ex vivo adipose DIO mouse model, the ED₅₀ for inhibition of 11β-HSD-1 in adipose tissue is 5.2 mg/kg.[1] |
| Enzyme Assay |
Human 11β-HSD-1 enzyme inhibition was assessed using a microsomal form of the enzyme at 37°C. The assay measures conversion of cortisone to cortisol (or DHC to corticosterone in rodents). Inhibition is quantified by IC₅₀ and Ki values using standard enzymatic kinetic analysis. Compound activity was tested in duplicate.[1]
PXR transactivation assay was performed to assess off-target liability, with EC₅₀ values reported for activation.[1] |
| Animal Protocol |
Animal/Disease Models: Diet-induced obesity (DIO) mice [1]
Doses: 10-100 mg/kg Route of Administration: po (po (oral gavage)) once Experimental Results: Inhibition of 11β-HSD-1 was observed as an indicator of diminished plasma corticosterone concentrations. ED50 is 34 mg/kg. Animal/Disease Models: Male Balb/C mouse[1] Doses: 5 or 10 mg/kg Route of Administration: IV or PO (pharmacokinetic/PK/PK analysis) Experimental Results: Single-dose pharmacokinetic/PK/PK parameters of BMS-823778[1] Species route dose (mg/kg) Cmax (μM) Tmax (h) AUC (0-24 h) (μM·h) T1/2 (h) CLTp (mL/min/kg) Vss (L/kg) F ( %) Mouse IV 5 - - 106 5.2 2.3 1.2 - PO 10 10.6 ± 1.3 3 95 - - - 44 PO Vehicle: 0.5% Methocel/0.1% Tween 80 IV Vehicle: 10% Ethanol/30% Propylene glycol/60% saline For pharmacodynamic assessment in mice and cynomolgus monkeys, BMS-823778 was administered orally prior to a challenge with dehydrocorticosterone (DHC). Plasma samples were collected at various time points, and corticosterone levels were measured by immunoassay to determine inhibition of 11β-HSD-1.[1] In the ex vivo adipose model, male DIO mice were treated orally with BMS-823778. Three hours later, adipose tissue was harvested and incubated with exogenous DHC to measure conversion to corticosterone.[1] |
| ADME/Pharmacokinetics |
In preclinical animal models, oral bioavailability ranged from 44% to 100%. [1]
BMS-823778 has a high adipose tissue to plasma concentration ratio. [1] In humans, systemic clearance is associated with CYP2C19 gene polymorphism. [1] |

| Additional Infomation |
BMS-823778 is a 1,2,4-triazolopyridylmethanol derivative developed as an 11β-HSD-1 inhibitor for the treatment of type 2 diabetes and metabolic syndrome. [1] Based on its favorable preclinical results, BMS-823778 has entered Phase II clinical trials. [1] Preliminary clinical trials have shown that BMS-823778 is safe and well-tolerated in healthy subjects after single and multiple oral doses. [1]
