BMS-066 is a novel and potent tricyclic pseudokinase inhibitors of IKKβ/Tyk2 with IC50s of 9 nM and 72 nM, respectively. It demonstrates potent in vitro potency, acceptable pharmacokinetic and physicochemical properties, and efficacy when dosed orally in a mouse model of inflammatory bowel disease.
| ln Vitro |
BMS-066 is more than 500 times more selective for IKKβ than the closely related IKKα and inhibits IKKβ-catalyzed phosphorylation of IKKβ in vitro with an IC50 of 9 nM. BMS-066 was tested at a concentration of 10 μM against an additional 155 kinases to obtain a more comprehensive understanding of its selectivity; only 6 of them showed better than 75% inhibition. This indicates that BMS-066 exhibits a selectivity of over 400 times for IKKβ when compared to 95% of the tested kinases. For the six kinases that exhibited more than 75% inhibition at 10 μM concentration, IC50 values were ascertained using a dose-response assay; BMS-066 demonstrated more than 30-fold stronger inhibition even when compared to the next most potent inhibitory kinase (Brk) selectivity. BMS-066 has IC50 values of about 200 nM for both protein and message levels, which are the levels at which it inhibits the production of cytokines in human peripheral blood mononuclear cells triggered by lipopolysaccharide (LPS). In LPS-stimulated cells, BMS-066 inhibits IKKβ-catalyzed IkBα phosphorylation with comparable IC50 values [1]. The Tyk2 pseudokinase domain probe replacement and IL-23-stimulated reporter gene tests have IC50 values of 72 and 1020 nM, respectively, for BMS-066 [2].

| ln Vivo |
At the end of the research, paw swelling was dramatically reduced in rats treated with vehicle compared to rats given oral doses of 5 and 10 mg/kg once daily, beginning at the time of adjuvant injection on Day 1. The high dose demonstrated nearly total suppression of paw swelling. The area of the talocrural (ankle) joint contracts. Within the joint area, inflammatory exudate with neutrophils and cellular debris was also visible. Animals given 10 mg/kg BMS-066 showed normal or barely changed bone resorption and joint inflammation. In addition to dramatically lowering inflammation, low-dose BMS-066 (5 mg/kg) also seems to cause more localized and milder bone resorption as compared to controls. Additionally, dose-dependent protection against substantial pitting, bone loss, woven porous bone, and ossicle fusion was demonstrated by BMS-066 in rats as revealed by hindlimb microcomputed tomography. Measurements of bone density also demonstrated the therapy with BMS-066 to have significant dose-dependent advantages. On the first day of dosing, measurements of serum drug levels in satellite mice revealed that a single dose (dose twice daily, 6 hours per day) covered the IC50 value for LPS-induced TNF-α in mouse whole blood for about 3 hours. Additionally, research has demonstrated that IKKβ inhibitors prevent the tissues in experimental arthritis models from producing TNF-α and IL-1β [1].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
