  Synthesis and Antibacterial Evaluation of Certain Quinolone Derivatives

  摘要：

  A number of 7-substituted quinolone derivatives were synthesized and evaluated for antibacterial and cytotoxic activities. Preliminary results indicated that most compounds tested in this study demonstrated better activity against methicillin-resistant Staphylococcus aureus than norfloxacin. Among them, 1-(4-amino-2-fluorophenyl)-6-fluoro-1,4-dihydro-7-{4-[2-(4-methoxyphenyl)-2-hydroxyiminoethyl]-1-piperazinyl}-4-oxo-3-quinolinecarboxylic acid (11d) and its ketone precursor 10d exhibited significant activities against Klebsiella pneumoniae, methicillin-resistant S. aureus, erythromycin- and ampicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus faecalis. Due to strong cytotoxicities of lid (a mean log GI(50) of -5.40), compound 10d, with good antibacterial activities and low cytotoxicities (a mean log GI(50) of -4.67), is a more potential drug candidate.

  某些氟喹诺酮衍生物的合成，抗分枝杆菌和细胞毒性评估

  摘要：

  合成了某些1-乙基和1-芳基-6-氟-1,4-二氢喹啉-4-酮衍生物，并评估了其抗分枝杆菌和细胞毒性的活性。初步结果表明，对于1-芳基-6-氟喹诺酮类化合物，7-（哌嗪-1-基）-和7-（4-甲基哌嗪-1-基）衍生物9b和11a均能够完全抑制生长。的结核分枝杆菌在6.25微克/ ml的浓度，而7- [4-（2-氧代-2-苯乙基）哌嗪-1-基]衍生物13所仅表现出31％的生长抑制在相同的浓度。对于1-乙基-6-氟喹诺酮类化合物，7- [4-（2-氧代丙基）哌嗪-1-基]-和7- [4-（2-氧代-2-苯基乙基）哌嗪-1-基]衍生物，2a和2b分别显示出完全的抑制作用，而它们的2-亚氨基乙基和取代的苯基对应物3a和2c的活性较低。另外，6,8-二氟衍生物比其6-氟衍生物（2b vs. 2d）是更有利的抑制剂。这些结果值得特别关注，因为2a，2b，9b和11a在100μM的浓度下无细胞毒性。此外

• A method of using synthetic L-SE-Methylselenocysteine as a nutriceutical and a method of its synthesis

  A synthesis of and use of L-Se-methylselenocysteine as a nutriceutical is described, based upon the knowledge that L-Se-methylselenocysteine is less toxic than L-selenomethionine towards normal cells. The synthesis proceeds by mixing N-(tert-butoxycarbonyl)-L-serine with a dialkyl diazodicarboxylate and at least one of a trialkylphosphine, triarylphosphine and phosphite to form a first mixture that includes N-(tert-butoxycarbonyl)-L-serine β-lactone. Methyl selenol or its salt is mixed with the N-(tert-butoxycarbonyl)-L-serine β-lactone to form a second mixture that includes N-(tert-butoxycarbonyl)-Se-methylselenocysteine. The text butoxycarbonyl group is removed from the N-(tert-butoxycarbonyl)-Se-methylselenocysteine to form L-Se-methylselenocysteine. This synthesis significantly improves the manufacturability, manufacturing efficiency and utility of this naturally occurring rare form of organic-selenium. L-Se-methylselenocysteine formed, for example, in this manner may be used as a nutriceutical for supplementation into the diets of humans or animals for various beneficial purposes, such as, for example, to prevent or reduce the risk of developing cancer.

  描述了一种合成和使用L-Se-甲硒氨酸作为一种营养保健品，基于L-Se-甲硒氨酸对正常细胞比L-硒蛋氨酸毒性较小的知识。合成过程包括将N-(叔丁氧羰基)-L-丝氨酸与二烷基重氮二羧酸酯和三烷基膦、三芳基膦和磷酸酯中的至少一种混合，形成包含N-(叔丁氧羰基)-L-丝氨酸β-内酯的第一混合物。甲硒醇或其盐与N-(叔丁氧羰基)-L-丝氨酸β-内酯混合，形成包含N-(叔丁氧羰基)-Se-甲硒氨酸的第二混合物。将N-(叔丁氧羰基)-Se-甲硒氨酸中的叔丁氧羰基团去除，形成L-Se-甲硒氨酸。这种合成显著改善了这种天然存在的稀有有机硒形式的可制造性、制造效率和实用性。例如，以这种方式形成的L-Se-甲硒氨酸可用作一种营养保健品，添加到人类或动物的饮食中，以达到各种有益目的，例如预防或减少患癌症的风险。
