RIPK3 inhibitor-AZD5423 alleviates acute kidney injury by inhibiting necroptosis and inflammation
Int Immunopharmacol 2022 Nov;112:109262.PMID:36166972DOI:10.1016/j.intimp.2022.109262.
Acute kidney injury (AKI) is a clinical syndrome that is defined as a sudden decline in renal function and characterized by inflammation and programmed cell death of renal tubular epithelial cells. Necroptosis is a form of regulated cell death that requires activation of receptor interacting protein kinase 3 (RIPK3) and its phosphorylation of the substrate MLKL. RIPK3 plays an important role in acute kidney injury, and hence developing its inhibitors is considered as one of the promising strategies aimed at prevention and treatment of AKI. Recently, we discovered AZD5423 as a novel potent RIPK3 inhibitor using a computer-aided hybrid virtual screening strategy according to three-dimensional structure of RIPK3. Our findings revealed that AZD5423 strongly inhibits activation of RIPK3, and MLKL phosphorylation upon cisplatin-, hypoxia/reoxygenation (H/R)- and TNF-α stimuli as compared with GSK872, which is a previously identified RIPK3 inhibitor. Importantly, AZD5423 exerts effective protection against cisplatin- and ischemia/reperfusion (I/R)-induced AKI mouse model. The results of cellular thermal shift assay and experiments in RIPK3 knockout cells indicated that AZD5423 could directly target RIPK3 to inhibit RIPK3 kinase activity. Mechanistically, the docking of AZD5423 and RIPK3 suggested that the kinase domain of RIPK3 for Lys50, Arg313, Lys29, Arg37 might form hydrogen bonds with AZD5423. Site-directed mutagenesis further revealed that AZD5423 reduces injury response via interacting with the key RIPK3 amino acid residues of Lys50 and Arg313. In conclusion, our study has demonstrated that AZD5423 may serve as a potent inhibitor of RIPK3 kinase and a promising clinical candidate for AKI treatment.
Pharmacokinetics of the Inhaled Selective Glucocorticoid Receptor Modulator AZD5423 Following Inhalation Using Different Devices
AAPS J 2017 May;19(3):865-874.PMID:28281196DOI:10.1208/s12248-016-0042-8.
AZD5423 is a non-steroidal glucocorticoid receptor modulator, with low aqueous solubility, developed for treatment of asthma and COPD. In this work, we aim to evaluate and compare the absorption pharmacokinetics (PK) of AZD5423 after inhalation via four devices, (Spira®, I-neb®, Turbuhaler® and a new dry powder inhaler (new DPI)) with two formulations using differently sized primary particles, and to compare the pulmonary bioavailability with the predicted lung deposited dose. Plasma concentration-time data after intravenous, oral and inhaled administration via four devices were available from two clinical studies in healthy and asthmatic subjects. A population PK modelling approach was taken to sequentially incorporate each route of administration, assuming parallel absorption compartments for inhaled AZD5423. A non-compartmental analysis for derivation of PK parameters was performed for comparison. Pulmonary bioavailability varied between devices, with the lowest estimates for I-neb (27%) and Turbuhaler (30%) and the highest for the new DPI (46%) and Spira (35-49%). The pulmonary bioavailability was substantially lower than the predicted lung deposited dose (range 59-90%). Lung absorption was separated into a faster and a slower process in the model. The half-life of the faster absorption appeared formulation-dependent, while the slower absorption (half-life of 0.59-0.78 h) appeared independent of formulation. The large difference in the estimated pulmonary bioavailability and the predicted lung deposited dose for AZD5423 implies an impact of mucociliary clearance. The lung absorption half-life indicates that AZD5423 is retained in the lung for a relatively short time.
Efficacy and Tolerability of an Inhaled Selective Glucocorticoid Receptor Modulator - AZD5423 - in Chronic Obstructive Pulmonary Disease Patients: Phase II Study Results
Basic Clin Pharmacol Toxicol 2017 Oct;121(4):279-289.PMID:28212463DOI:10.1111/bcpt.12768.
AZD5423 is a novel, inhaled, selective glucocorticoid receptor modulator (SGRM), which in an allergen challenge model in asthma patients improved lung function and airway hyper-reactivity. In the current trial, AZD5423 was for the first time tested in patients with chronic obstructive pulmonary disease (COPD). In this double-blind, randomized and parallel group study, we examined airway and systemic effects of two doses of AZD5423, inhaled via Turbuhaler for 12 weeks, in 353 symptomatic patients with COPD (average pre-bronchodilator forced expiratory volume in one-second (FEV1) at screening was 50-52% of predicted normal). Pre-bronchodilator FEV1 was primary variable, with other lung function parameters plus symptoms and 24-hr plasma cortisol being secondary variables. Plasma concentrations of AZD5423 were also measured. Effects were compared against placebo and a reference glucocorticoid receptor agonist control. Neither AZD5423, at doses which have shown to be efficacious in allergen-induced asthma, nor the reference control, at double the approved dose, had any clinically meaningful effect in the patient population studied in regard to lung function or markers of inflammation. Both GR modulators were well tolerated and did suppress 24-hr cortisol. This study suggests that the selected population of patients with COPD does not respond to treatment with AZD5423 as regards lung function, while showing the expected systemic effects. It cannot be ruled out that a favourable lung function response of AZD5423 can be evoked using another experimental setting and/or within a different population of patients with COPD.
A nonsteroidal glucocorticoid receptor agonist inhibits allergen-induced late asthmatic responses
Am J Respir Crit Care Med 2015 Jan 15;191(2):161-7.PMID:25473939DOI:10.1164/rccm.201404-0623OC.
Rationale: Effective antiinflammatory therapies are needed for the treatment of asthma, but preferably without the systemic adverse effects of glucocorticosteroids. Objectives: We evaluated the effect of an inhaled nonsteroidal glucocorticoid receptor agonist, AZD5423, on allergen-induced responses. Methods: Twenty subjects with mild allergic asthma were randomized to receive 7 days of treatment with nebulized AZD5423 (75 or 300 μg) once daily, budesonide 200 μg twice daily via Turbuhaler, or placebo in a double-blind, four-period, crossover design study. Allergen challenge was performed on Day 6. Measurements and main results: FEV1 was measured repeatedly for 7 hours after allergen challenge for early and late asthmatic responses. Sputum inflammatory cells was measured before and at 7 and 24 hours after allergen challenge, and methacholine airway responsiveness was measured before and 24 hours after allergen challenge. AZD5423 significantly attenuated the fall in FEV1 during the late asthmatic response (both doses led to an 8.7% fall) versus placebo (14% fall) (P < 0.05) with no effect of budesonide (12.5% fall) versus placebo (P > 0.05). There was no effect on the fall in FEV1 during early asthmatic response. AZD5423 300 and 75 μg significantly attenuated allergen-induced sputum eosinophilia by 63 and 61% at 7 hours, respectively, and by 46 and 34% at 24 hours after allergen challenge, respectively, versus placebo (all P < 0.05). Budesonide did not reduce allergen-induced sputum eosinophilia versus placebo. AZD5423 at 300 μg significantly attenuated allergen-induced airway hyperresponsiveness at 24 hours after allergen challenge versus placebo (P < 0.05). Both doses of AZD5423 were well tolerated. Conclusions: Seven-day treatment with inhalation of the nonsteroidal glucocorticoid receptor agonist AZD5423 effectively reduced allergen-induced responses in subjects with mild allergic asthma.

Experimental Glucocorticoid Receptor Agonists for the Treatment of Asthma: A Systematic Review
J Exp Pharmacol 2020 Aug 6;12:233-254.PMID:32982485DOI:10.2147/JEP.S237480.
Inhaled corticosteroids (ICSs) are considered the cornerstone of asthma treatment. Despite the solid evidence documenting the efficacy and safety of ICSs at the level of the airways, their use can be affected by pulmonary and systemic adverse events (AEs) when administered chronically and/or at high doses. Thus, there is a pharmacological and medical need for new glucocorticoid (GC) receptor (GR) ligands with a more favorable therapeutic index, in order to overcome the shortcomings of currently available ICSs. The therapeutic profile of GCs can be improved by enhancing genomic mechanisms mediated by transrepression, which is assumed to be responsible for several anti-inflammatory and immunomodulatory actions, rather than transactivation, which causes most of the GC-associated AEs. It was assumed that an independent modulation of the molecular mechanisms underlying transactivation and transrepression could translate into the dissociation of beneficial effects from AEs. Therefore, current research is looking for GCs that are able to elicit prevalently transrepression with negligible transactivating activity. These compounds are known as selective glucocorticoid receptor agonists (SEGRAs). In this review, experimental GR agonists currently in pre-clinical and clinical development for the treatment of asthma have been systematically assessed. Several compounds are currently under pre-clinical development, but only three novel experimental GR agonists (GW870086X, AZD5423, AZD7594) seem to have some potential therapeutic relevance and have entered clinical trials for the treatment of asthma. Since data from pre-clinical studies have not always been confirmed in clinical investigations, well-designed randomized controlled trials are needed in asthmatic patients to confirm the potentially positive benefit/risk ratio of each specific SEGRA and to optimize the development strategy of these agents in respiratory medicine.
