Abstract

(5Z)-7-Oxozeanol and related analogues were isolated and screened to explore their activity as TAK1 inhibitors. Seven analogues were synthesized and more than a score of natural products isolated that examined the role that different areas of the molecule contribute to TAK1 inhibition. A novel nonaromatic difluoro-derivative was synthesized that had similar potency compared to the lead. This is the first example of a nonaromatic compound in this class to have TAK1 inhibition. Covalent docking for the isolated and synthesized analogues was carried out and found a strong correlation between the observed activities and the calculated binding.

摘要

分离并筛选了(5Z)-7-氧代泽烷醇及其相关类似物,以探索它们作为TAK1抑制剂的活性。合成了七种类似物,并分离出二十多种天然产物,研究了分子不同区域对TAK1抑制作用的贡献。合成了一种新型非芳香二氟衍生物,其效力与先导物相似。这是该类非芳香化合物中首个具有TAK1抑制作用的例子。对分离和合成的类似物进行了共价对接,发现观察到的活性与计算出的结合之间存在很强的相关性。
