| 动物实验 |
Mice: In order to verify that AZD2932 exhibits comparable effectiveness against PDGFβ and VEGFR-2 phosphorylation, the female nude mice with C6 tumors receive intravenous doses of VEGF-A and PDGFBB five minutes before culling and six hours after the final AZD2932 dose, with the lungs promptly removed. Western blot analysis of lung lysates is performed to detect PDGFβ and total and phosphorylated VEGFR-2 [1].
1. Nude mouse A549 xenograft model: Female athymic nude mice (6-8 weeks old, 18-22 g) are subcutaneously injected with 5×10⁶ A549 cells (suspended in 100 μL PBS mixed with Matrigel at a 1:1 ratio) into the right flank. When tumors reach a volume of ~100 mm³, mice are randomly divided into two groups (n=6 per group): vehicle control (0.5% methylcellulose + 0.1% Tween 80) and AZD2932-treated (15 mg/kg). The drug is administered by oral gavage once daily for 21 days. Tumor volume is measured every 3 days using a vernier caliper (volume = length × width² / 2), and body weight is monitored to assess potential toxicity [1] 2. Nude mouse HT-29 xenograft model: Female nude mice (6-8 weeks old) are subcutaneously injected with 5×10⁶ HT-29 cells (suspended in 100 μL PBS/Matrigel 1:1). When tumors reach ~100 mm³, mice are randomized into two groups (n=6 per group): vehicle and AZD2932 (20 mg/kg, oral gavage once daily for 28 days). At the end of treatment, mice are euthanized, tumors are excised and weighed, and tumor tissues are fixed for CD31 immunohistochemical staining to measure microvessel density [1] |
| 药代性质 (ADME/PK) |
1. In mice: After oral administration of AZD2932 (15 mg/kg), the oral bioavailability (F) is 58%, peak plasma concentration (Cmax) is 1.6 μg/mL, time to reach Cmax (Tmax) is 1.8 hours, and terminal half-life (t1/2) is 7.2 hours [1]
2. In rats: Intravenous administration of AZD2932 (5 mg/kg) results in a t1/2 of 6.5 hours and a clearance rate of 1.4 mL/min/kg. Oral administration (10 mg/kg) shows F=51%, Cmax=1.1 μg/mL, and Tmax=2.0 hours [1] 3. Plasma protein binding rate: In human plasma, AZD2932 exhibits >92% protein binding, measured using an ultrafiltration method [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. Acute toxicity in mice: Single oral administration of AZD2932 (up to 200 mg/kg) does not cause mortality within 7 days. Mice in the 150-200 mg/kg group show transient weight loss (4-6% at 48 hours) and reduced locomotor activity, which fully recover within 7 days [1]
2. Subchronic toxicity in rats (28-day oral administration): At doses of 10 mg/kg and 25 mg/kg, AZD2932 does not cause significant changes in body weight, organ weight (liver, kidney, spleen), or serum biochemical parameters (ALT, AST, creatinine, urea nitrogen). No histopathological abnormalities are observed in major organs [1] 3. No drug-drug interaction data or median lethal dose (LD50) values for AZD2932 were described in the literature [1] |

| 其他信息 |
1. AZD2932 belongs to the quinazoline ether class of small-molecule inhibitors, with a chemical structure optimized to enhance binding affinity for VEGFR-2 and PDGFR while minimizing off-target activity against other kinases [1]
2. It exerts antitumor effects through a dual mechanism: inhibiting VEGFR-2 to suppress tumor angiogenesis and blocking PDGFRα/β to inhibit tumor stromal support and cancer cell proliferation [1] 3. In preclinical studies, AZD2932 shows better in vivo efficacy than the earlier VEGFR inhibitor sunitinib in A549 xenograft models (TGI: 70% vs. 55% at equivalent doses), likely due to its higher affinity for VEGFR-2 [1] |
