Hence, we designed eight peptides (compounds 1-8). We compared their performances; compound 8 had the best transfection efficacy and biocompatibility. The transfection effect was similar with that of PEI, a most-widely-employed commercial transfection reagent. Atomic force microscope (AFM) images showed that the compound could self-assemble and the self-assembled peptide might encapsulate DNA. Based
非病毒载体因其安全性和低免疫原性而在基因递送领域得到发展。但它们的转染效果通常很低,从而限制了其应用。因此,我们设计了八种肽(化合物1-8)。我们比较了他们的表现;化合物8的转染效果和生物相容性最好。转染效果与最广泛使用的商业转染试剂PEI相似。原子力显微镜 (AFM) 图像显示该化合物可以自组装,并且自组装肽可能封装 DNA。基于这些结果,我们进一步分析了对癌细胞的抑制结果,发现化合物8可以部分对抗Hela细胞。因此,该化合物有望为开发更有效、毒性更低的转染载体铺平道路。
