• Development of Scaled-Up Synthetic Method for Retinoid X Receptor Agonist NEt-3IB Contributing to Sustainable Development Goals

  Small-molecular drugs, which are generally inexpensive compared with biopharmaceuticals and can often be taken orally, may contribute to the Sustainable Development Goals (SDGs) adopted by the United Nations. We previously reported the retinoid X receptor (RXR) agonist 4-(ethyl(3-isobutoxy-4-isopropylphenyl)amino)benzoic acid (NEt-3IB, 1) as a small-molecular drug candidate to replace biopharmaceuticals for the treatment of inflammatory bowel disease. The previous synthetic method to 1 required a large amount of organic solvent and extensive purification. In line with the SDGs, we aimed to develop an environmentally friendly, inexpensive method for the large-scale synthesis of 1. The developed method requires only a hydrophobic ether and EtOH as reaction and extraction solvents. The product was purified by recrystallization twice to afford 99% pure 1 at 100 mmol scale in about 30% yield. The optimized process showed a 35-fold improvement of the E-factor (an index of environmental impact) compared to the original method. This work, which changes the solvent used to environmentally preferable ones based on the existing synthetic method for 1, illustrates how synthetic methods for small-molecular drugs can be adapted and improved to contribute to the SDGs.

  与生物制药相比，小分子药物通常价格低廉，而且通常可以口服，这可能有助于实现联合国通过的可持续发展目标（SDGs）。我们曾报道过视黄醇 X 受体（RXR）激动剂 4-(乙基(3-异丁氧基-4-异丙基苯基)氨基)苯甲酸（NEt-3IB，1），它是一种可替代生物制药治疗炎症性肠病的候选小分子药物。以往合成 1 的方法需要使用大量有机溶剂并进行大量纯化。根据可持续发展目标，我们旨在开发一种环保、廉价的方法来大规模合成 1。产物经两次重结晶纯化，在 100 毫摩尔规模下可得到纯度为 99% 的 1，收率约为 30%。与原始方法相比，优化工艺的 E 因子（环境影响指数）提高了 35 倍。这项工作在现有 1 号合成方法的基础上，将所用溶剂改为对环境更有利的溶剂，说明了如何调整和改进小分子药物的合成方法，为可持续发展目标做出贡献。
