Novel pyrazinone mono-amides as potent and reversible caspase-3 inhibitors
摘要:
The iterative process for the discovery of a series of pyrazinone mono-amides as potent, selective and reversible non-peptide caspase-3 inhibitors (e.g., M826 and M867) is reported. These compounds display potent anti apoptotic activities in a number of cell based systems in vitro as well as in several animal models in vivo. (C) 2004 Elsevier Ltd. All rights reserved.
fungal species was Trichoderma viride, while Penicillium versicolor var. cyclopium appeared to be the most resistant. It should be mentioned that in general most of the compounds showed weaker antibacterial activity, but better antifungal properties than usnic acid itself. The results allow us to conclude that the title compounds are good lead compounds for novel more active antibacterial drugs. On the
松萝酸是一种二苯并呋喃,最初是从产生次生代谢产物的地衣中分离出来的,作为一种抗生素而闻名,但还具有其他一些有趣的特性。因此,本文的目的是设计新的松萝酸衍生物并评估其抗菌活性。所有新合成的化合物均具有良好的抗菌活性,MIC范围为1.02–50.93 × 10 -2 mmol mL -1,MBC范围为2.05–70.57 × 10 -2 mmol mL -1。最敏感的细菌种类是金黄色葡萄球菌,而铜绿假单胞菌和大肠杆菌是 ATCC 菌株中耐药性最强的,MRSA 是所有测试细菌(ATCC 和临床分离株)中耐药性最强的。它们的抗真菌活性非常强(MIC = 0.35–7.53 × 10 -2 mmol mL -1和 MFC = 0.70–15.05 × 10 -2 mmol mL -1)——优于参考化合物和松萝酸本身。最敏感的真菌物种是绿色木霉,而杂色青霉变种。cyclopium似乎是最具抵抗力的。应
