MedKoo Cat#: 206182 | Name: AZD3759
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Zorifertinib (AZD3759) is an orally bioavailable, brain-penetrant epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) developed specifically to treat non-small cell lung cancer (NSCLC) with EGFR-activating mutations and central nervous system (CNS) metastases. It exhibits high potency against mutant EGFR, particularly the L858R and exon 19 deletion variants, with in vitro IC₅₀ values in the low nanomolar range (e.g., ~5–10 nM for EGFR-L858R). Notably, AZD3759 achieves cerebrospinal fluid (CSF) concentrations sufficient to inhibit intracranial tumor growth, a limitation of earlier EGFR TKIs. In preclinical models, it demonstrated robust antitumor activity in both intracranial and extracranial xenografts.

Biological target:
AZD3759 inhibits EGFR. At Km ATP concentrations, the IC50s are 0.3, 0.2, and 0.2 nM for EGFRwt, EGFRL858R, and EGFRexon 19Del, respectively.
In vitro activity:
First, the effect of radiation and AZD3759 on cell proliferation in NSCLC cell lines expressing either wild type (WT) (H2228 and H226) or mutant EGFR (H3255 and PC-9) using MTS assay was investigated (Fig. 1a). AZD3759 alone significantly inhibited the proliferation of H3255 and PC-9 cells, with GI50 7.6 nM and 8.9 nM, respectively. Whereas, EGFR WT cells were insensitive to AZD3759, with GI50 > 5 μM in H226 cells and hardly any effect in H2228 cells. When AZD3759 was combined with radiation, a synergistic effect on inhibiting of cell proliferation was detected in H3255 cells treated with 10 nM AZD3759 and in PC-9 cells treated with 30 nM AZD3759 (CI < 1, Supporting Information Table S1 and Fig. S1), whereas an antagonistic effect was detected when AZD3759 at the low concentration (<10 nM in H3255 cells and <30 nM in PC-9 cells). In H226 and H2228 cells, there was antagonistic effect even the concentration of AZD3759 was up to 30 μM (CI > 1, data not shown). The survival of cells treated with either radiation or AZD3759 in combination with radiation by using CFA (Fig. 1b and Supporting Information Table S2) was evaluated next. In PC-9 cells, a synergistic effect on inhibiting cell survival was detected when 10 nM AZD3759 was combined with radiation, with DEF of 1.82 (p < 0.0001, AZD3759 10 nM with radiation vs. radiation alone). In contrast, there was no synergistic effect when AZD3759 at the concentration of 5 nM (p = 0.383, AZD3759 5 nM with radiation vs. radiation alone), even a radiosensitizing effect was detected (DEF = 1.1). Similarly, there was no synergistic effect by AZD3759 and radiation in H226 cells either, even the concentration of AZD3759 was increased to higher than 100 nM. These results demonstrate that both the sensitivity to AZD3759 and the concentration of AZD3759 are essential for synergistic effect between AZD3759 and radiation.

In vivo activity:
Following oral dosing in rats at 2 mg/kg, absorption of Zorifertinib (AZD3759) is rapid with blood Cmax of 0.58 μM achieved at 1.0 h. Subsequently, blood concentrations of Zorifertinib decline monoexponentially with a mean elimination half-life of 4.3 h, which is close to the same parameter obtained from intravenous dosing of 4.1 h. The bioavailability following an oral dose in rats is 91%. Blood pharmacokinetic parameters of Zorifertinib in male dogs are determined following both a single dose intravenous infusion and oral administration. Following the IV dose in dogs, Zorifertinib blood clearance is determined as 14 mL/min per kg, and the volume of distribution is 6.4 L/kg. Its elimination half-life is 6.2 h. Absorption of Zorifertinib is rapid with blood Cmax (698 nM) occurring between 0.5 and 1.5 h. The oral bioavailability of Zorifertinib is excellent at 90%. Zorifertinib demonstrated significant dose-dependent antitumor efficacy (78% tumor growth inhibition at 7.5 mg/kg qd and tumor regression at 15 mg/kg qd, respectively, 4 weeks after treatment) with <20% body weight loss, whereas CP-358774 has a limited effect in this model. At the end of the study, brain tissues are collected for histological assessment. Significantly decreased tumor area is observed by Zorifertinib treatment at the doses of 7.5 and 15 mg/kg. In addition, modulation of pEGFR is detected by a single dose of Zorifertinib at 15 mg/kg 1h after dosing, which confirmed target engagement by Zorifertinib.
