Biological Activity of AZD2858

DescriptionAZD2858 is a potent, orally active GSK-3 inhibitor, with IC50s of 0.9 and 5 nM for GSK-3α and GSK-3β, respectively, used in the research of fracture healing.In Vitro:AZD2858 (1 μM) increases β-catenin levels after a short period of time in human osteoblast cells. AZD2858 inhibits GSK-3β dependent phosphorylation with an IC50 of 68 nM. AZD2858 (10 nM) has no effect on β-catenin levels[1]. AZD2858 increases TAZ expression and osterix expression both by 1.4-fold, with EC50 of 440 nM and 1.2 μM, respectively, in hADSC. AZD2858 also induces a marked increase in osteogenic mineralisation in hADSC[3]. AZD2858 (AR28) demonstrates from 70- to greater than 6000-fold selectivity over a panel of other kinases and an IC50 of 5 nM. AR28 inhibits GSK-3 in murine cells and indicates activation of the canonical Wnt/β-catenin signaling cascade. AR28 (50, 10, and 1 nM) enhances the clonogenic ability of mesenchymal progenitors with osteogenic and adipogenic potential. AR28 (50 µM) also enhances the differentiation ability of mesenchymal progenitors to the osteogenic but not adipogenic lineage in vitro[4].In Vivo:AZD2858 (20 mg/kg) causes a dose-dependent increase in trabecular bone mass compared to control after a two-week treatment with a maximum effect[1]. AZD2858 exhibits a substantial effect on fracture healing. AZD2858 (20 mg/kg) causes an increase in cortical BMC of 9%, cortical area of 10%, and cortical thickness of 11% at 3 weeks in the non-operated right femur of rats[2]. AZD2858 (30 μmol/kg/day) alters the biomarkers of bone turnover with statistically significant increases in P1NP and decreases in TRAcP-5b seen from 3 days of treatment and onwards. AZD2858 demonstrates significant changes in serum bone turnover markers (P1NP and TRAcP-5b) and femur bone formation after only 7 days of daily dosing[3]. AZD2858 (AR28, 30 mg/kg, s.c.) stimulates an increase in an initial wave of mesenchymal progenitors with osteogenic and adipogenic potential and drives their differentiation to the osteogenic lineage in BALB/c mice. AR28 (30 mg/kg, s.c.) enhances the proliferation of committed hematopoietic progenitors and their differentiation to the osteoclast lineage but does not prevent an overall increase in bone mass[4].

Protocol

Kinase Assay [3]
The potency of compounds at GSK-3β and cyclin-dependent protein kinase 2 (CDK2, kinase with closest homology to GSK-3β) is assessed using Z-LYTE™ Kinase assay kit in the presence of 7 and 80 μM ATP respectively. A ratiometric method is used to calculate the ratio of donor emission (445 nm) to acceptor emission (520 nm) after excitation of the donor fluorophore at 400 nm to quantitate the reaction progress. Kinase selectivity with AR79, AZD2858 and AZ13282107 are determined using the KinaseProfiler Service or University of Dundee Kinase. Over 80 different kinases are assessed at a single concentration of 1 or 10 μM of AR79, AZD2858 and AZ13282107. Concentration-inhibition 10-point curves to compounds that show activity are constructed to determine pIC50 estimations. Also, in some kinase assays these pIC50 estimations are converted to binding affinity values (pKi) using the Cheng-Prussoff equation to correct for the concentration of ATP used[3].

Animal Administration [1]
Each rat is dosed orally with vehicle or AZD2858 using a plastic gavage tube. The dose volume is 10 mL/kg. The vehicle consists of deionized water adjusted to pH 3.5±0.1. Formulations are adjusted to pH 3.5±0.1. The doses are 0, 0.2, 2 or 20 mg/kg respectively and administered either twice daily (TD), once daily (OD), every other day (O/2D), or every fourth day (O/4D) for 14 days. In total, the protocol results in 13 groups with 8 animals in each group (104 animals). At 7 days after the start of the study, and again 2 days prior to the scheduled terminal necropsy, each animal is injected subcutaneously with a bicarbonate buffered calcein solution (8 mg/kg, 1 mL/kg)[1].

Background on AZD2858

AZD2858 is a selective GSK-3 inhibitor with IC50 value of 68 nM.
Glycogen synthase kinase 3β (GSK-3β) plays an important role in the canonical Wnt pathway and participates in many biological processes [1].
In human osteoblast cells, AZD2858 increased β-catenin levels in a short time [1]. Incubation of hADSC with AZD2858 led to a significantly increase in osteogenic mineralisation. This indicated that inhibition of GSK-3 enhanced osteogenic differentiation of hADSC [2].
Treatment rats with AZD2858 orally increased trabecular bone mass in a dose-dependent way after a two-week treatment. The significant effect was also seen at cortical sites. Both vertebral compression strength and diaphyseal strength of femora increased in biomechanical testing. Furthermore, there was a dramatic increase in bone formation indices, serum markers of both bone formation and resorption were also elevated [1]. Also, AZD2858 drives mesenchymal cells into osteoblastic cells and leads to direct bone repair in an unstable fracture milieu [3].

Rats treated with AZD2858, a GSK3 inhibitor, heal fractures rapidly without endochondral bone formation.[Pubmed:23337038]

Bone. 2013 May;54(1):126-32.

Fracture healing is a complex interplay between endochondral and intramembranous bone formation processes. The canonical Wnt/beta-catenin pathway enhances new bone formation and may play a role in fracture healing. Glycogen synthase kinase 3beta (GSK3beta) is a key regulator of beta-catenin degradation. In this study, we investigate the effects of AZD2858, an orally bioactive GSK3 inhibitor, on fracture healing. Femoral fractures were produced in rats after the insertion of a femoral nail. The rats were treated with oral administration of AZD2858 at a dose of 30 mumol/kg (20mg/kg) daily for up to 3 weeks, while control animals were administered vehicle. At 4days, and at 1, 2 and 3 weeks, histological analysis was performed, and at the 2 and 3 week time points, we performed peripheral quantitative computed tomography (pQCT), X-rays, and four-point bending tests. Peripheral QCT showed an increase in both mineral density (of 28% at 2 weeks and 38% at 3weeks) and mineral content (of 81% at 2 weeks and 93% at 3 weeks) in the calluses from AZD2858 treated animals as compared to vehicle treated animals. Histological analysis demonstrated that rats treated with GSK3 inhibitor healed their fractures rapidly, but without the pre-formation of cartilage tissue. Furthermore, four-point bending tests of fractured femora from animals treated for 2 and 3 weeks showed an increase in strength in treated animals compared to their vehicle-treated controls. In conclusion, AZD2858, a potent GSK3 inhibitor, has a substantial impact on fracture healing. The fractures healed with a bony callus without an obvious endochondral component, suggesting that AZD2858 drives mesenchymal cells into the osteoblastic pathway. This leads to direct bone repair in an unstable fracture milieu.
