8-(methylsulfonylamino)quinoline (8-MSQ) was identified as a hit. Through computational modeling and synthetic elaboration, a potent GLO1 inhibitor was developed with a novel sulfonamide core pharmacophore. A lead compound was demonstrated to penetrate the blood-brain barrier, elevate levels of methylglyoxal in the brain, and reduce depression-like behavior in mice. These findings provide the basis
焦虑和抑郁是常见的高度共病的精神疾病,占全世界医学残疾的很大比例。乙二醛酶1(GLO1)已被确定为治疗焦虑症和抑郁症的可能靶标。GLO1是一种Zn2 +依赖性酶,可将由谷胱甘肽和甲基乙二醛形成的半硫缩醛异构化为乳酸硫酯。为了开发GLO1的活性抑制剂,基于片段的药物发现被用于鉴定可用作铅开发核心支架的片段。在筛选了聚焦于金属结合药效基团的文库后,鉴定出了8-(甲基磺酰基氨基)喹啉(8-MSQ)。通过计算建模和合成,开发了一种具有新型磺酰胺核心药效基团的有效GLO1抑制剂。铅化合物被证明可以穿透血脑屏障,提高大脑中甲基乙二醛的水平,并减少小鼠的抑郁样行为。这些发现为GLO1抑制剂治疗抑郁症和相关的精神疾病提供了依据。
