噻唑和哌嗪是两个重要的杂环化合物,在自然界中发挥着重要的作用,在农业和药物化学中有着广泛的应用。在这里,我们报告了一个不同的哌嗪系联的噻唑化合物文库的平行合成。哌嗪与新生成的4-氯甲基-2-氨基噻唑反应,得到纯度高、总收率高的哌嗪并噻唑类化合物。用多种市售的羧酸平行合成了多种双取代的4-(哌嗪-1-甲基)噻唑-2-胺衍生物。化合物的筛选导致了抗疟原虫化合物的鉴定,这些化合物表现出有趣的抗疟疾活性,主要针对抗恶性疟原虫氯喹抗性的DD2株。HIT化合物2291-61对氯喹抗性DD2株的抗疟原虫EC50为102 nM,选择性超过140。
Thiazole and piperazine are two important heterocyclic rings that play a prominent role in nature and have a broad range of applications in agricultural and medicinal chemistry. Herein, we report the parallel synthesis of a library of diverse piperazine-tethered thiazole compounds. The reaction of piperazine with newly generated 4-chloromethyl-2-amino thiazoles led to the desired piperazine thiazole compounds with high purities and good overall yields. Using a variety of commercially available carboxylic acids, the parallel synthesis of a variety of disubstituted 4-(piperazin-1-ylmethyl)thiazol-2-amine derivatives is described. the screening of the compounds led to the identification of antiplasmodial compounds that exhibited interesting antimalarial activity, primarily against the Plasmodium falciparum chloroquine-resistant Dd2 strain. The hit compound 2291-61 demonstrated an antiplasmodial EC50 of 102 nM in the chloroquine-resistant Dd2 strain and a selectivity of over 140.
