1 (JAK1) is implicated in multiple inflammatory pathways that are critical for the pathogenesis of asthma, including the interleukin (IL)-4, IL-5, IL-13, and thymic stromal lymphopoietin cytokine signaling pathways, which have previously been targeted to treat allergic asthma. Here, we describe the development of AZD0449 and AZD4604, two novel and highly selective JAK1 inhibitors with promising properties for inhalation.\n\nThe effects of AZD0449 and AZD4604 in JAK1 signaling pathways were assessed by measuring phosphorylation of signal transducer and activator of transcription (STAT) proteins and chemokine release using immunoassays of whole blood from healthy human volunteers and rats. Pharmacokinetic studies performed on rats evaluated AZD0449 at a lung deposited dose of 52 \u03bcg/kg and AZD4604 at 30 \u00b5g/kg. The efficacy of AZD0449 and AZD4604 was assessed by evaluating lung inflammation (cell count and cytokine levels) and the late asthmatic response (average enhanced pause [Penh]).\n\nBoth compounds inhibited JAK1-dependent cytokine signaling pathways in a dose-dependent manner in human and rat leukocytes. After intratracheal administration in rats, both compounds exhibited low systemic exposures and medium-to-long terminal lung half-lives (AZD0449, 34 hours; AZD4604, 5 hours). Both compounds inhibited STAT3 and STAT5 phosphorylation in lung tissue from ovalbumin (OVA)-challenged rats. AZD0449 and AZD4604 also inhibited eosinophilia in the lung and reduced the late asthmatic response, measured as Penh in the OVA rat model.\n\nAZD0449 and AZD4604 show potential as inhibitors of signaling pathways involved in asthmatic immune responses, with target engagement demonstrated locally in the lung. These findings support the clinical development of AZD0449 and AZD4604 for the treatment of patients with asthma.", "doi": "10.2147/DDDT.S354291", "pmid": "36068788", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC9441147"}, {"db": "pii", "key": "354291"}], "notes": [], "created": "2026-08-21T12:55:21.199Z", "modified": "2026-08-21T12:55:21.937Z"}, {"entity": "publication", "iuid": "3c2b3091c1024994a1ffc2f667b40668", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/3c2b3091c1024994a1ffc2f667b40668.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/3c2b3091c1024994a1ffc2f667b40668"}}, "title": "Immunogenetics in systemic lupus erythematosus: Transitioning from genetic associations to cellular effects.", "authors": [{"family": "Hagberg", "given": "Niklas", "initials": "N", "orcid": "0000-0003-2064-2716", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/be3f2835d0c04a85af2d67c158b17b06.json"}}, {"family": "Lundtoft", "given": "Christian", "initials": "C", "orcid": "0000-0001-5872-4253", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/f22eef009e944f069fe779e7f3cb2eff.json"}}, {"family": "R\u00f6nnblom", "given": "Lars", "initials": "L"}], "type": "journal article", "published": "2020-10-00", "journal": {"title": "Scand.
