OSW-1 产品活性：OSW-1 是从虎眼万年青中分离出来的，osterol-binding protein (OSBP) 和 OSBP-elated protein 4 (ORP4) 的特异性拮抗剂，其在人类肿瘤细胞系中的 GI50 值为纳摩尔级别。 产品来源： https://www.medchemexpress.cn/OSW-1.html 研究领域：Others 作用靶点：Others 来源：植物 | 百合科 | 虎眼万年青 结构分类：甾体类 | 结构分类 In Vitro: OSW-1 has a strong inhibitory effect on colon carcinoma cells with low cytotoxicity on normal cells. The anti-proliferative effects of OSW-1 on SW480 and LoVo colon carcinoma cells are characterized by measuring cell viability using the CCK8 assay, and compared the results with other clinical anticancer agents. SW480 and LoVo cell lines are derived from a Dukes' stage B colon carcinoma and a colon carcinoma metastatic nodule, which represent non-metastatic and metastatic carcinomas, respectively. OSW-1 exhibits not only extremely strong anticancer activity in SW480 and LoVo cell lines with an IC50 of nanomolar concentration, but is also more potent than other anticancer agents by 10-100 times, with a lower cytotoxic effect on normal epithelial cells. These results indicate that OSW-1 has a powerful anticancer effect, but lower cytotoxic effect on normal cells. In Vivo: To ascertain whether or not OSW-1 is as effective in vivo, a nude mouse model inoculated by LoVo cells is adopted, in which OSW-1 treatment is performed when tumors became palpable. The results show that the size of tumors in treated mice is smaller on average than control mice. The significant difference is observed from the 15-17 th day following treatment, and this difference is gradually increased until the animals are sacrificed. Compared with the control group, the tumor weight of the OSW-1-treated group significantly decreases (P<0.05). Additionally, no apparent side effects are observed in OSW-1-treated mice. These results demonstrate that OSW-1 has powerful effects on suppressing colon tumor growth without significant side effects in vivo. 相关产品：Natural Product Library Plus | Bioactive Compound Library Plus | Digitonin | 5-Ph-IAA | FLAG peptide | 3X FLAG peptide | TCEP hydrochloride | Monocrotaline | Tocofersolan | Pronase E (Activity ≥ 7000 U/g) | DPPH | DNase I, Bovine pancreas | NMDI14 | O-Propargyl-Puromycin | Human IgG1 kappa, Isotype Control | Phytohemagglutinin | Hyaluronidase | Biotinyl tyramide | MYLS22 | Pertussis Toxin | N,N-Dimethylformamide | Kifunensine | OVA Peptide (323-339) | L-Tryptophan | 6-Aminonicotinamide | Lauryl maltose neopentyl glycol | Alkyne-phenol | Potassium oxonate | OVA Peptide(257-264) TFA | CHAPS | Teriparatide 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
