    The synthesis of condensation products of 4‐hydroxycoumarin and nitro‐substituted aromatic aldehydes as well as oximes of drugs with anticoagulant activity is described. The acute toxicity of the compounds was studied in mice by oral and intraperitoneal administration. A comparative pharmacological study of the in vivo anticoagulant effects of Warfarin derivatives showed that the new compounds have

    Abstract

    Three kinds of 4-hydroxycoumarin derivatives, namely, biscoumarins (1–4), epoxydicoumarins (5–8) and dihydropyrans (9–12), were synthesized and the antibacterial activity of each of them was evaluated. The result of preliminary bioassay shows that the lowest minimal inhibitory concentration (MIC) of compounds 1 and 2 against drug-sensitive S. aureus (ATCC 29213) and methicillin-resistant S. aureus (MRSA XJ 75302, Mu50, ATCC 700699 and USA 300) is 4–64 ug/mL. Additionally, there are two classical intramolecular O—H⋯O hydrogen bonds (HBs) in the structures of biscoumarins (1–4), and their corresponding HB energies were further calculated by the density functional theory (DFT) [B3LYP/6-31G*] method.

    摘要:合成了三种4-羟基香豆素衍生物,分别为双香豆素(1-4)、环氧双香豆素(5-8)和二氢吡喃(9-12),并评估了它们的抗菌活性。初步生物测定结果显示,化合物1和2对药物敏感型金黄色葡萄球菌(ATCC 29213)和耐甲氧西林金黄色葡萄球菌(MRSA XJ 75302、Mu50、ATCC 700699和USA 300)的最低最小抑制浓度(MIC)为4-64 ug/mL。此外,双香豆素(1-4)的结构中存在两个经典的分子内O—H⋯O氢键(HBs),并且它们的对应HB能量进一步通过密度泛函理论(DFT)[B3LYP/6-31G*]方法计算。
