AZD8848 is a selective toll-like receptor 7 (TLR7) antedrug agonist which is developed for the research of asthma and allergic rhinitis[1].

IC50 & Target


In Vitro

AZD8848 shows good activity against TLR7, with cellular pEC50s of 7.0 and 6.6 for human TLR7 and rat TLR7, respectively[1].
AZD8848 has an EC50 of 4 nM in the induction of IFNα from human PBMCs and an IC50 of 0.2-1.0 nM for the inhibition of IL-5, irrespective of whether the T cells have been polyclonally stimulated with PHA or via antigen presentation[1].
AZD8848 is a potent, selective TLR7 agonist antedrug able to inhibit Th2 responses in vitro[1].
AZD8848 has no activity against human TLR8 or against any of the other human TLRs[1].

In Vivo

AZD8848 (0.1-1 mg/kg; intratracheal) has a good pharmacokinetics in the Brown Norway rat[1].
AZD8848 (0.3 mg/kg; Intratracheal) suppresses the ovalbumin (OVA) challenge in the rat allergy model[1].

Animal Model: Brown Norway rat allergy model[1]
Dosage: 0.1 mg/kg, 1 mg/kg
Administration: Intratracheal (24 hours prior to and 24 hours after the OVA challenge)
Result: Suppressed OVA challenge in a dose-dependent manner.
Animal Model: Brown Norway rat[1]
Dosage: 0.3 mg/kg (Pharmacokinetic Analysis)
Administration: Intratracheal
Result: Has a very short half-life (0.2 min) in rat blood and declined slowly after this point and levels above 1000 nmol/kg were maintained for over 5 hours.
