  Non-natural oligomers have recently shown promise as functional analogues of lung surfactant proteins B and C (SP-B and SP-C), two helical and amphiphilic proteins that are critical for normal respiration. The generation of non-natural mimics of SP-B and SP-C has previously been restricted to step-by-step, sequence-specific synthesis, which results in discrete oligomers that are intended to manifest specific structural attributes. Presented herein an alternative approach to SP-B mimicry that is based on sequence-random copolymers containing cationic and lipophilic subunits. These materials, members of the nylon-3 family, are prepared by ring-opening polymerization of β-lactams. The best of the nylon-3 polymers display promising in vitro surfactant activities in a mixed lipid film. Pulsating bubble surfactometry data indicate that films containing the most surface-active polymers attain adsorptive and dynamic-cycling properties that surpass those of discrete peptides intended to mimic SP-B. Attachment of an N-terminal octadecanoyl unit to the nylon-3 copolymers affords further improvements by reducing the percent surface area compression to reach low minimum surface tension.

  非天然低聚物最近有望成为肺表面活性蛋白 B 和 C（SP-B 和 SP-C）的功能类似物，这两种螺旋状两亲性蛋白对正常呼吸至关重要。以前，SP-B 和 SP-C 的非天然模拟物的生成一直局限于分步、序列特异性合成，从而产生离散的低聚物，以显示特定的结构属性。本文介绍的另一种 SP-B 拟态方法是基于含有阳离子和亲油亚单位的序列随机共聚物。这些材料属于尼龙-3 家族，是通过 β-内酰胺的开环聚合反应制备的。最好的尼龙-3 聚合物在混合脂膜中显示出良好的体外表面活性。脉动气泡表面活性测定法的数据表明，含有表面活性最强的聚合物的薄膜所具有的吸附性和动态循环特性超过了用于模拟 SP-B 的离散肽。在尼龙-3 共聚物上连接一个 N 端十八碳酰单位可降低表面积压缩百分比，从而达到较低的最小表面张力，从而进一步提高了性能。

  Disclosed is a method of making β-polypeptides. The method includes polymerizing β-lactam-containing monomers in the presence of a base initiator and a co-initiator which is not a metal-containing molecule to yield the product β-polypeptides. Specifically disclosed are methods wherein the base initiator is potassium t-butoxide, lithium bis(trimethylsilyl)amide (LiN(TMS) 2 ), potassium bis(trimethyl-silyl)amide, and sodium ethoxide, and the reaction is carried out in a solvent such as chloroform, dichloromethane, dimethylsulfoxide, or tetrahydrofuran.
