AZD7507 是一种有效且具有口服活性的 CSF-1R 抑制剂，具有抗肿瘤活性。
AZD7507 is a potent and selective CSF-1R inhibitor (32 nM cell activity), AZD7507 is considered a promising compound as it retained the desired potency and oral pharmacokinetic properties of AZ683. Moreover, in a telemetry study in dogs given a single oral dose, there was no cardiovascular toxicity, no elevation of troponin related to the treatment, and no alteration in the ECG.

Animal experiment: | Mice[2]Male CD1 nude mice are injected subcutaneously with 5 × 105 human ICC cells from human cell line WITT-1, CC-LP-1, or SNU-1079 (n = 24 in all cases) suspended in culture media/RGF Matrigel (Gibco) mix (1:1). Cells are engrafted bilaterally in the flank and allowed to form tumors over 3 weeks. Once palpable tumors have formed, mice are randomized into 3 groups using GraphPad online software. Xenografted mice are injected with liposomal clodronate at 4 μL/g intravenously. The control for this treatment is saline alone or liposomes not containing clodronate (both given at 4 μL/g intravenously). All of these treatments are given every 48 hours for 3 weeks. CSFR1 inhibitors AZD7507 and GW2580 are made up in sterile water containing 0.5% methylcellulose and 0.1% Tween-80. AZD7507 is given twice daily at 100 mg/kg, whereas GW2580 is given daily at 160 mg/kg. Control animals are given water containing 0.5% methylcellulose and 0.1% Tween-80. ICG-001 (5 mg/kg) or C-59 (20 mg/kg) is given by intraperitoneal injection. The vehicle for this is physiological saline. Control animals are given vehicle alone. In all cases inhibitors and vehicle are given 3 times per week[2]. |
