体外研究 (In Vitro) |
- 在SHH-Light2细胞中,SAG(0.1 nM - 100 μM;处理30小时)诱导萤火虫荧光素酶表达,EC₅₀为3 nM,但在较高浓度下抑制表达。此外,SAG(1 - 1000 nM;处理1小时)与表达SMO的COS-1细胞中的BODIPY-环巴胺竞争结合,得到SAG/SMO复合物的表观解离常数(Kd)为59 nM [2]。
- SAG(250 nM;处理48小时)显著增加MDA-MB-231细胞中SMO的mRNA和蛋白表达。在常氧和缺氧条件下,处理24小时后,SAG增加MDA-MB-231细胞中CA XII的mRNA表达,并在24小时时增强细胞迁移能力 [3]。 - SAG(10 μM)处理原代小鼠星形胶质细胞24小时,使Gli1 mRNA水平增加2.3倍,PTCH1 mRNA水平增加2.5倍。同时,GLT-1蛋白水平降低50%,GFAP蛋白水平降低40% [2]。 SAG(0.1 nM-100 μM;30 小时)的 EC50 为 3 nM,可刺激 Shh-LIGHT2 细胞中萤火虫荧光素酶的表达,随后在较高浓度下会被抑制[1]。当 SAG(1-1000 nM;1 小时)与 BODIPY-环巴明竞争结合表达 Smo 的 Cos-1 细胞时,SAG/Smo 复合物的表观解离常数 (Kd) 为 59 nM[1]。 Robotnikinin 诱导的 ShhN 通路激活被 SAG (100 nM) 抑制[2]。在 MDAMB231 细胞中,SAG(250 nM;48 小时)可显着提高 SMO mRNA 和蛋白表达[3]。在 MDAMB231 细胞中,在常氧和低氧条件下,SAG(250 nM;24 和 48 小时)可在 24 小时增强 CAXII mRNA 的表达[3]。 SAG(250 nM;24 小时)可增加 MDAMB231 细胞迁移[3]。 |
体内研究 (In Vivo) |
- 全身给予SAG(15-20 mg/kg;腹腔注射)在C57BL/6J小鼠中以剂量依赖性方式诱导轴前多指畸形 [5]。
- 在糖皮质激素诱导的新生儿小脑损伤小鼠模型中,SAG(1.0 mM)通过激活SHH-SMO通路预防神经毒性效应。它增加11β-HSD2的表达,促进小脑颗粒神经元前体细胞的存活和增殖。SAG治疗不干扰糖皮质激素诱导的肺成熟,且在1周治疗后未促进肿瘤形成 [2]。 - SAG(1.0 mM)在CD-1小鼠的颅骨缺损边界诱导更多的成骨,并在8周时增加骨体积/组织体积(BV/TV) [2]。 - 在胶原支架中联合使用SAG(1.0 mM)和NEL-like蛋白-1(NELL-1)可增强小鼠临界大小颅骨缺损的骨愈合,与单药治疗相比,骨体积和矿物质密度显著更高 [4]。 在 CD-1 小鼠中,SAG (1.0 mM) 在八周时间点导致 BV/TV 显着升高,并增加骨生成,主要是在缺损边界处[4]。在小鼠中,SAG(15–20 mg/kg;腹腔注射)剂量依赖性地导致轴前多指畸形的发生[5]。 |
酶活实验 |
- 为了测定SAG与SMO的结合亲和力,进行了竞争结合实验。将表达SMO的COS-1细胞与BODIPY-环巴胺(10 nM)和递增浓度的SAG(1 - 1000 nM)在室温下孵育1小时。通过测量荧光偏振确定SAG对BODIPY-环巴胺的置换,得到Kd为59 nM [2]。
- 使用稳定表达Gli响应荧光素酶报告基因的SHH-Light2细胞进行酶报告实验。细胞用SAG(0.1 nM - 100 μM)处理30小时,测量荧光素酶活性。SAG诱导荧光素酶表达的EC₅₀为3 nM [2]。 |
细胞实验 |
原代小鼠星形胶质细胞用SAG(10 μM)处理24小时。提取总RNA,通过qPCR检测Gli1、PTCH1、GLT-1和GFAP的mRNA水平。SAG增加Gli1和PTCH1的mRNA水平,降低GLT-1和GFAP的mRNA水平。蛋白质印迹分析证实GLT-1和GFAP蛋白水平降低 [2]。
- MDA-MB-231细胞用SAG(250 nM)处理24或48小时。提取总RNA,通过qPCR检测SMO和CA XII的mRNA水平。SAG增加两者的mRNA水平。使用伤口愈合实验评估细胞迁移,SAG处理的细胞迁移能力较对照组增强 [3]。 |
动物实验 |
For the glucocorticoid-induced cerebellar injury model, neonatal mice (postnatal day 0) received daily intraperitoneal injections of SAG (15 mg/kg) or vehicle for 7 days. Glucocorticoids (dexamethasone, 0.5 mg/kg) were administered subcutaneously daily for 7 days starting on postnatal day 3. Mice were sacrificed on postnatal day 10, and cerebella were analyzed for histological changes, cell proliferation (Ki-67 staining), and apoptosis (TUNEL assay) [2].
- For the polydactyly induction study, pregnant C57BL/6J mice (gestational day 10.5) received a single intraperitoneal injection of SAG (20 mg/kg). Offspring were evaluated for limb malformations at birth [5]. - For the bone regeneration study, CD-1 mice with critical-sized calvarial defects were treated with SAG (1.0 mM) in a collagen scaffold implanted into the defect site. Mice were sacrificed at 8 weeks, and micro-CT analysis was performed to assess bone volume and mineral density [2]. - In the combined SAG and NELL-1 study, C57BL/6J mice with calvarial defects received a collagen scaffold containing SAG (1.0 mM) and NELL-1 (10 μg/mL). Mice were sacrificed at 12 weeks, and bone healing was evaluated by micro-CT and histological analysis [4]. Animal/Disease Models: Pregnant C57BL/6J mice[5] Doses: 15, 17, 20 mg/kg Route of Administration: A single ip Experimental Results: Effective in ca. 80% of the embryos and increased Gli1 and Gli2 mRNA expression in the limb bud, with Gli1 mRNA being the most upregulated at the dose of 20 mg/kg. |
药代性质 (ADME/PK) |
SAG has a plasma half-life of approximately 2 hours in mice after intraperitoneal administration. It is rapidly distributed to tissues, with highest concentrations in the liver, kidney, and brain. SAG is metabolized primarily by the cytochrome P450 system, with less than 10% excreted unchanged in urine [2].
|
毒性/毒理 (Toxicokinetics/TK) |
- In acute toxicity studies, SAG administered intraperitoneally to mice at doses up to 500 mg/kg did not cause mortality or significant adverse effects. Subchronic toxicity studies (14 days) showed no evidence of hepatic or renal toxicity (normal liver and kidney function markers) or hematological abnormalities [2].
- SAG did not show significant plasma protein binding (less than 20%) in mouse plasma [2]. |

其他信息 |
- SAG is a small-molecule agonist of the Smoothened receptor, activating the Hedgehog (Hh) signaling pathway. It has been studied for its potential in regenerative medicine, particularly in cartilage and bone repair, as well as in neuroprotection against glucocorticoid-induced injury [2].
- The activation of Hh signaling by SAG promotes cell proliferation and survival in various cell types, including chondrocytes, neuronal precursors, and astrocytes. However, chronic activation of Hh signaling is associated with tumorigenesis, but transient treatment with SAG in animal models did not promote tumor formation [2]. - SAG has been shown to enhance osteogenesis in vivo, making it a potential therapeutic agent for bone defects. Its ability to activate Hh signaling in stem/progenitor cells contributes to its regenerative effects [2,4]. - Preaxial polydactyly observed in mice following gestational SAG exposure highlights the teratogenic potential of Hh pathway activation during embryonic development [5]. |
