CP-547632

WARNING: This product is for research use only, not for human or veterinary use.

Description:CP-547632, also known as PAN-90806,is as a potent inhibitor of the VEGFR-2 and basic fibroblast growth factor (FGF) kinases (IC50 11 and 9 nM, respectively). It is selective relative to epidermal growth factor receptor, platelet-derived growth factor , and other related TKs. It also inhibits VEGF-stimulated autophosphorylation of VEGFR-2 in a whole cell assay with an IC50 value of 6 nM. After oral administration of CP-547,632 to mice bearing NIH3T3/H-ras tumors, VEGFR-2 phosphorylation in tumors was inhibited in a dose-dependent fashion (EC50 590 ng/ml). CP-547,632 is a well-tolerated, orally-bioavailable inhibitor presently under clinical investigation for the treatment of human malignancies.

Technical Data

Additional Information

Phase I/II trial results:   Seventy patients were enrolled and 68 patients were treated, 37 in phase 1 and 31 in phase 2 (14 with the combination and 17 with chemotherapy alone). Dose-limiting toxicity of CP-547,632 250 mg by mouth daily in combination with paclitaxel and carboplatin was grade 3 rash and grade 3 diarrhea despite medical intervention. CP-547,632 did not significantly affect the pharmacologic profiles of paclitaxel and carboplatin. No subject had CR. In phase I, seven subjects (22.6%) had a confirmed partial response. In phase II, four subjects (28.6%) receiving CP-547,632 plus chemotherapy had a confirmed partial response. In the phase II chemotherapy alone group, four subjects (25%) had a confirmed partial response. CONCLUSION:  The combination of CP-547,632 and paclitaxel and carboplatin was well-tolerated at doses up to 200 mg by mouth daily. Dose-limiting toxicity of CP-547,632 at 250 mg consisted of diarrhea and rash. CP-547,632 did not increase the objective response rate to chemotherapy alone in patients with advanced non-small cell lung cancer. (source: Cancer Chemother Pharmacol. 2007 Jun;60(1):81-9.

CRISPR-Cas9是近年兴起的用于靶向基因组特定位置，进行DNA修饰的重要工具。研究发现CRISPR是细菌为了应对病毒的攻击而演化而来的获得性免疫防御机制。具体来说，在CRISPR和Cas9的作用下，经由小RNA分子的引导，靶向并沉默入侵者遗传物质核酸的关键部分。在该系统中，crRNA（CRISPR-derivedRNA）与tracrRNA（trans-activatingRNA）结合形成的复合物能特异性识别靶基因序列，并引导Cas9核酸内切酶在靶定位点剪切双链DNA，随后，细胞的非同源末端连接修复机制（NHEJ）重新连接断裂处的基因组DNA，并引入插入或缺失突变。另外也可以提供一个外源双链供体DNA（Donor）通过同源重组（HR）整合进断裂处的基因组，从而达到对基因组DNA进行修饰的目的。
目前，CRISPR-Cas9系统的高效基因组编辑功能已被应用于多种生物，包括小鼠、大鼠、斑马鱼、秀丽隐杆线虫，也包含多种细菌和植物，甚至在人体上也有应用。
