Screening of a small compound library at the three excitatoryaminoacidtransportersubtypes 1–3 (EAAT1–3) resulted in the identification of compound (Z)-4-chloro-3-(5-((3-(2-ethoxy-2-oxoethyl)-2,4-dioxothiazolidin-5-ylidene)methyl)furan-2-yl)benzoic acid (1a) that exhibited a distinct preference as an inhibitor at EAAT1 (IC50 20 μM) compared to EAAT2 and EAAT3 (IC50 > 300 μM). This prompted us to
在三种兴奋性氨基酸转运蛋白亚型1-3(EAAT1-3)上筛选小型化合物文库,从而鉴定出化合物(Z)-4-氯-3-(5-((3-(2-乙氧基- (2-氧代乙基)-2,4-二氧噻唑烷-5-亚甲基)呋喃-2-基)苯甲酸(1a)与EAAT2和EAAT3(EA 50)相比在EAAT1(IC 50 20μM)上表现出明显的抑制作用( IC 50 > 300μM)。这促使我们接受主题1a通过购买,合成和随后的总共36种类似物的药理学表征,进行详细的构效关系研究。尽管这种努力并未导致与通过点击显示的类似物在EAAT1上具有显着改善的抑制效能,但它提供了对该支架的EAAT1活性的结构要求的详细见解。这类新的EAAT1选择性抑制剂的发现不仅补充了EAAT领域目前可用的药理学工具,而且证实了非α-氨基酸衍生的EAAT配体在亚型选择性调节方面具有相当大的潜力。运输者。

The present invention relates to certain heterocyclic compounds of formula (1) that have the ability to inhibit lysine biosynthesis via the diaminopimelate biosynthesis pathway in certain organisms. As a result of this activity these compounds can be used in applications where inhibition of lysine biosynthesis is useful. Applications of this type include the use of the compounds as herbicides.

antibacterial and herbicidal agents. Herein, we report the discovery and exploration of the first inhibitors of E. coli DHDPS which have been identified from screening lead and are not based on substrates from the lysine biosynthesis pathway. Over 50 thiazolidinediones and related analogues have been prepared in order to thoroughly evaluate the structure-activityrelationships against this enzyme of significant
