  摘要：

  急性肺损伤（ALI）的致死率很高，白细胞介素6（IL-6）和肿瘤坏死因子-α（TNF-α）在ALI病例中对组织恶化的影响最大。在这项研究中，我们基于先前鉴定的先导化合物设计并合成了一系列新的噻唑并[3,2-a]嘧啶衍生物，并评估了它们的抗炎活性。结构-活性关系研究导致发现了两种高效抑制剂。发现这两种有前途的化合物以剂量依赖性方式抑制小鼠原发性腹膜巨噬细胞（MPM）中脂多糖（LPS）诱导的IL-6和TNF-α释放。此外，这些化合物的施用导致肺组织病理学改善并且在体内减弱了LPS诱导的ALI。综上所述，这些数据表明这些新颖的噻唑罗[3，

  2,2'-Dimers with a central double bond were prepared by the oxidation of 5,6-disubstituted 7-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-3(2H)-ones with DMSO and Lawesson's reagent at room temperature. The role of DMSO as an oxidizing reagent was confirmed by NMR spectroscopy. The E-configuration of the central C=C bond for the two diastereomers of compound 8m was proven by single crystal X-ray data. The dimeric thiazolopyrimidines were orange or red colored and absorption bands at 283-330 and 459-476 nm were observed in the UV spectra. (C) 2018 Elsevier Ltd. All rights reserved.

  2‐Thioxo/oxo‐1,2,3,4‐tetrahydropyrimidine‐5‐carboxylate derivatives 2a, 2b, 2c, 2d were prepared by the reaction of ethyl acetoacetate and thiourea or urea with aldehydes using NH4Cl as a catalyst. Compounds 2a and 2c reacted with mono and bihalogenated compounds such as ethyl iodide, chloroacetonitrile, epichlorohydrin, acetyl chloride, ethyl bromoacetate, chloroacetic acid, chloroacetylchloride, and/or oxalyl chloride to afford compounds 3, 4a, 4b, 5, 6a, 6b, 7, 8, 9 and 10, respectively. Compounds 2a, 2c, and 7 were allowed to react with p‐fluorobenzaldehyde to yield the corresponding products 11a, 11b, and 12, respectively. Oxidation of 2a and 2c gave 2b, 13a, 13b, 14, 15, 16 dependent on the oxidizing agent used. Vilsmeiere‐Haack formylation of 2a and 2b with POCl3/DMF afforded 17a and 17b. Chlorination of 2b and 2d gave the chlorinated derivative 18a and 18b, which reacted with thiourea to give thioureidopyrimidine 19a and 19b. Reactions of 2a with hydrazine monohydrate, semicarbazide hydrochloride, and sodium hydroxide gave compounds 20, 21, 22, respectively. The cytotoxicity and in vitro anticancer evaluation of some prepared compounds have been assessed against two different human tumor cell lines including breast adenocarcinoma MCF‐7 and human hepatocellular carcinoma HepG2. Antimicrobial and antioxidant activities of some compounds were investigated. The newly synthesized compounds were characterized by IR, 1H‐NMR, 13C‐NMR, and mass spectral data.
