摘要

奎宁基聚合物已显示出有效递送核酸的希望；然而，奎宁的疏水性经常导致配合物不受控制的聚集（bbb1000nm）。聚乙二醇化常用于提高核酸递送载体的胶体稳定性；然而，这经常导致细胞内化减少。本文中，我们描述了两种二嵌段奎宁聚合物的合成，它们利用碳水化合物葡萄糖和半乳糖代替PEG作为中性亲水性嵌段来传递mRNA。这些二嵌段稳定剂与五种疏水性奎宁聚合物以不同的混合比例混合，产生73种配方库，其中47种产生亚微米颗粒。生物物理特性，如颗粒大小和mRNA结合，可以通过改变混合物的成分和比例来调节。我们的研究结果表明，下一代含糖稳定剂优于聚乙二醇化类似物，促进更大的细胞内化，改善转染，并具有细胞特异性的潜力。

Blending Carbohydrate and Quinine-Based Polymers Imparts Colloidal Stability, Improved Performance, and Cell Specificity for mRNA Delivery

Quinine-based polymers have shown promise for effective delivery of nucleic acids; however, quinine’s hydrophobicity has often resulted in uncontrolled aggregation (>1000 nm) of complexes. PEGylation is often used to improve the colloidal stability of nucleic acid delivery vehicles; however, this frequently results in reduced cellular internalization. Herein, we describe the synthesis of two diblock quinine polymers that utilize the carbohydrates glucose and galactose in place of PEG as the neutral hydrophilic block to deliver mRNA. These diblock stabilizers were blended with five hydrophobic quinine polymers at several mixing ratios to generate a library of 73 formulations, 47 of which produced submicron particles. The biophysical properties, such as particle size and mRNA binding, can be tuned by varying the mixture components and ratio. Our results show that the next generation, sugar-containing stabilizers outperformed PEGylated analogs, promoting greater cellular internalization, improved transfection, and potential for cell specificity.
