  Vasoactive Thiomethyl-Pyrimidines: Promising Drug Candidates with Vascular Activity

  摘要：

  Pyrimidines and their derivatives are present in various biologically active molecules. Most of the synthetic methods employed to achieve the pyrimidinone ring consist of two stages: the synthesis of a Michael intermediate from an aldehyde and an "active methylene" containing compound; and the condensation of this intermediate with a molecule containing an uranium moiety. This may take one to two days of laboratory work. In this paper we describe a new methodology in which these derivatives are obtained via multicomponent synthesis mediated by ultrasound in only 2 hours. In order to obtain water-soluble pyrimidinone derivatives, our previous compounds were further converted into their sodium salts. In pharmacologic studies, these salts inhibited phenylephr-ineinduced contraction in isolated rat aorta, suggesting that they may act as alpha-1 antagonists and, therefore, are candidates for anti-hypertensive drugs.

  Novel Pyrimidinone Derivatives: Synthesis, Antitumor and Antimicrobial Evaluation

  摘要：

  以6-芳基-4-氧代-2-硫代-1,2,3,4-四氢嘧啶-5-碳腈（4a–d）为起始材料，合成了一系列单烷基和双烷基衍生物5a–j和6a，b。对4a、b、d和5d进行肼解反应，得到肼基衍生物7a–c，随后通过与甲酸和氯乙酰氯反应环化，分别得到三唑嘧啶酮8a–c和嘧啶三嗪酮9a–c。大多数新合成的化合物经过体外抗肿瘤活性评估。化合物6a和b在对白血病、非小细胞肺癌、黑色素瘤和肾癌方面表现出良好的抗癌活性。另一方面，所有合成的化合物均经过体外抗菌和抗真菌活性筛选。化合物5h和j对金黄色葡萄球菌表现出显著活性，而化合物5e、7c和8c对白色念珠菌表现出中等抑制活性。

  One-pot, multicomponent reaction for the synthesis of 4-aryl-5-cyano-1,6-dihydro-2-thiouracils via three-component from aromatic aldehydes, ethyl 2-cyanoacetate and S-benzylisothiourea hydrochloride (methyl carbamimidothioate sulfate) under methanol is described. These compounds have many drug activities, such as anti-hepatitis C viral, anti-Severe acute respiratory syndrome and anti-HIV-1 integrese activity. The advantages of this procedure include the short reaction time, mild reaction conditions and excellent yields.
