| 动物实验 |
1. GIST-T1 xenograft tumor model: Female NOD/SCID mice (6-8 weeks old) were injected subcutaneously with 2×10⁶ GIST-T1 cells into the right flank; tumors were allowed to reach 100-150 mm³ before treatment initiation; AZD3229 was formulated in 10% DMSO, 40% PEG400, and 50% sterile saline, and administered orally via gavage at 10, 30, or 100 mg/kg once daily for 21 days (volume: 10 mL/kg); tumor volume was measured every 3 days (volume = length × width² / 2), and mice were euthanized at study end for tumor weight measurement and tissue collection [2]
2. HMC-1.2 systemic mastocytosis model: NOD/SCID mice were injected intravenously with 5×10⁶ HMC-1.2 cells; 7 days post-injection, AZD3229 (30 mg/kg PO qd) or vehicle was administered for 14 days; at study end, spleen and bone marrow were harvested, and mast cell infiltration was quantified by flow cytometry (c-Kit/CD117 staining); serum tryptase levels were measured by ELISA [2] 3. KIT K642E drug-resistant GIST model: GIST cells expressing KIT K642E were implanted subcutaneously into NOD/SCID mice; once tumors reached 150 mm³, mice were treated with AZD3229 (50 mg/kg PO qd) or imatinib (100 mg/kg PO qd) for 21 days; tumor growth was monitored twice weekly, and tumor lysates were analyzed by western blot for phospho-KIT levels [2] 4. Pharmacodynamic sampling protocol: GIST-T1 xenograft mice were treated with a single dose of AZD3229 (30 mg/kg); tumors were harvested at 1, 4, 12, and 24 hours post-dosing; protein lysates were prepared for western blot analysis of phospho-KIT to determine the duration of target inhibition [2] |
| 药代性质 (ADME/PK) |
1. In male Sprague-Dawley rats, oral administration of AZD3229 (10 mg/kg) resulted in a peak plasma concentration (Cmax) of 320 nM at 1.5 hours (Tmax), oral bioavailability (F) of 68%, terminal half-life (t1/2) of 6.2 hours, volume of distribution (Vd) of 2.1 L/kg, and total clearance (CL) of 0.3 L/h/kg [2]
2. In cynomolgus monkeys, AZD3229 (5 mg/kg PO) had a Cmax of 280 nM (Tmax = 2 hours), t1/2 = 7.5 hours, and F = 62%; steady-state concentrations were achieved after 7 days of once-daily dosing, with an accumulation ratio of 1.2 [2] 3. AZD3229 exhibited high plasma protein binding in rat, monkey, and human plasma (94%, 96%, and 97%, respectively) [2] 4. The drug showed good tumor penetration in GIST-T1 xenografts, with a tumor/plasma concentration ratio of 1.8 at 4 hours post-dosing in mice [2] 5. AZD3229 was primarily metabolized by CYP3A4 (75%) and CYP2C9 (20%) in human liver microsomes; the major oxidative metabolite (M1) had <5% activity against KIT (IC50 = 250 nM) [2] 6. Less than 10% of the parent drug was excreted unchanged in rat urine and feces over 48 hours; 85% of the dose was excreted as metabolites, with fecal excretion (65%) exceeding urinary excretion (20%) [2] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. AZD3229 showed no significant cytotoxicity in normal human gastrointestinal epithelial cells (HIEC) at concentrations up to 10 μM, with cell viability >90% after 72-hour treatment (MTS assay) [2]
2. Acute toxicity studies in CD-1 mice revealed no mortality or overt toxicity at oral doses up to 2000 mg/kg or intravenous doses up to 100 mg/kg [2] 3. In a 28-day subchronic toxicity study in rats, AZD3229 (30, 100, 300 mg/kg PO qd) caused mild decreases in body weight (<10%) only at the 300 mg/kg dose; no significant changes in liver (ALT, AST) or kidney (BUN, creatinine) function markers were observed at doses ≤100 mg/kg [2] 4. Histopathological examination of major organs (liver, kidney, heart, spleen) in treated rats showed no treatment-related lesions at doses ≤100 mg/kg [2] 5. In vitro CYP450 inhibition assays demonstrated that AZD3229 weakly inhibited CYP3A4 (IC50 = 9.2 μM) and did not inhibit CYP1A2, CYP2C19, or CYP2D6 at concentrations up to 10 μM, indicating a low risk of drug-drug interactions [2] 6. No genotoxicity was observed in the Ames test, chromosome aberration assay, or micronucleus test with AZD3229 at concentrations up to 10 μM [2] |

1. AZD3229 is a potent, selective, and orally bioavailable pan-KIT mutant inhibitor developed by AstraZeneca for the treatment of gastrointestinal stromal tumors (GIST) and systemic mastocytosis [2]
2. The mechanism of action of AZD3229 involves competitive binding to the ATP-binding pocket of KIT kinase, inhibiting autophosphorylation and downstream signaling (PI3K/AKT, MAPK/ERK) in KIT-mutant cells, leading to G1 cell cycle arrest and apoptosis [2] 3. AZD3229 is active against imatinib-resistant KIT mutations (e.g., K642E, D816V), which are common in relapsed GIST and systemic mastocytosis [2] 4. Preclinical data demonstrate that AZD3229 exhibits superior efficacy to imatinib in drug-resistant KIT-mutant models, making it a promising candidate for second-line treatment of GIST [2] 5. AZD3229 has not received FDA approval and is in the preclinical development stage; no clinical trials have been initiated as of the publication of [2] [2] |
