Novel compounds comprising a C—C double bond substituted at one carbon with two sulfur atom-containing groups are disclosed. The compounds are useful in methods and compositions for generating chemiluminescence rapidly by reaction with a peroxidase enzyme and a peroxide. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.

Synthetic processes and intermediates are disclosed for the preparation of N-arylacridancarboxylic acid derivatives. The derivatives are esters, thioesters, amides and sulfonimides. A key feature of the processes is the preparation of N-aryl substituted intermendiates by formation of a bond between the nitrogen atom of the acridan ring and a carbon atom of another aromatic or heteroaromatic ring compound. The arylation reaction is catalyzed by a palladium catalyst. The N-arylacridancarboxylic acid derivatives are useful in methods for producing light and in assays for peroxidase enzymes and enzyme inhibitors and in assays employing enzyme-labeled specific binding pairs.

dehydrogenase (IMPDH), a crucial enzyme required for denovo synthesis of guanine nucleotides, is an attractive TB drug target. Herein, we describe the identification of potent IMPDH inhibitors using fragment-based screening and structure-based design techniques. Screening of a fragment library for Mycobacterium thermoresistible ( Mth) IMPDH ΔCBS inhibitors identified a low affinity phenylimidazole derivative
结核病 (TB) 仍然是全世界死亡的主要原因,需要改进治疗以对抗耐药性的出现。肌苷 5'-单磷酸脱氢酶 (IMPDH) 是从头合成鸟嘌呤核苷酸所需的关键酶,是一种有吸引力的结核病药物靶点。在这里,我们描述了使用基于片段的筛选和基于结构的设计技术来鉴定有效的 IMPDH 抑制剂。筛选耐热分枝杆菌 (Mth) IMPDH ΔCBS 抑制剂的片段库确定了一种低亲和力苯基咪唑衍生物。第 M 个 IMPDH ΔCBS-IMP-抑制剂复合物的 X 射线晶体学显示该片段的两个分子结合在 IMPDH 的 NAD 结合口袋中。
