exploration, and optimization of a lead structure that had shown good initial in vitro activity by interacting with RCAR/(PYR/PYL) receptor proteins, a key biochemical target of plant hormone abscisic acid. In the course of the in-depth SAR study, several new potent sulfonamide lead structures with higher target affinity and, more importantly, improved in vivo efficacy against drought stress in broad-acre crops
在本文所述的 SAR 研究中,分析、探索和优化通过与 RCAR/(PYR/PYL) 受体蛋白(植物激素脱落酸的关键生化靶标)相互作用而显示出良好的初始体外活性的先导结构。在深入的 SAR 研究过程中,确定了几种新的强效磺酰胺先导结构,与最初的先导结构相比,它们具有更高的靶点亲和力,更重要的是,在大面积作物油菜和小麦中,它们在体内对抗干旱胁迫的功效有所提高。
