  6-Aminoquinolones as New Potential Anti-HIV Agents

  摘要：

  A series of 6-aminoquinolone compounds were evaluated for their in vitro activity against human immunodeficiency virus type 1 (HIV-1). Compound 12a, bearing a methyl substituent at the N-1 position and a 4-(2-pyridyl)-1-piperazine moiety at the C-7 position, was the most active in inhibiting HIV-1 replication on de novo infected C8166 human lymphoblastoid cell lines. The 12a EC50 value was 0.1 mu M, a 7-20-fold lower concentration relative to that for compounds 8a and 7a containing a cyclopropyl and tert-butyl substituent at the N-1 position, respectively. When the C-6 amino group was replaced with a fluorine atom, a decreased antiviral effect was observed. The observed effects are selective, since potency is substantially reduced when testing the compounds against the herpes simplex virus type 1 (HSV-1). Active quinolone derivatives very efficiently interact with TAR RNA, which suggests a nucleic acid-targeted mechanism of action.

  6-氨基喹诺酮类：一类新的喹诺酮类抗菌剂？

  摘要：

  通过先前的QSAR研究设计了一系列喹诺酮和1,8-萘啶酮-3-羧酸，它们的特征是在C-6位置的氨基而不是通常的氟原子，并进行了首次体外抗菌活性。所有合成的化合物都对革兰氏阴性菌保持良好的活性（铜绿假单胞菌除外），并且具有硫吗啉基作为C-7取代基的那些化合物也对革兰氏阳性菌具有良好的活性。还讨论了与C-1，C-5，C-7和C-8取代基相关的结构活性关系的某些方面。衍生物18g和38g对革兰氏阴性菌和革兰氏阳性菌分别具有0.45和0.66-0.76微克/ mL的几何平均MIC的最佳活性。这种抗菌活性反映了它们抑制细菌DNA旋转酶的能力。这项研究的结果表明，尽管C-6氟仍然是优选的取代基，但仍可通过用氨基取代而获得良好的活性。

  Various 1-(substituted)-1,4-dihydro-6-nitro-4-oxo-7-(sub-secondary amino)-quinoline-3-carboxylic acids were synthesized from 2,4-dichlorobenzoic acid by six step synthesis. The compounds were evaluated for antimycobacterial in vitro and in vivo against Mycobacterium tuberculosis H37Rv (MTB), multi-drug resistant Mycobacterium tuberculosis (MDR-TB) and Mycobacterium smegmatis (MC2) and also tested for the ability to inhibit the supercoiling activity of DNA gyrase from M. smegmatis. Among the 48 synthesized compounds, 7-(4-((benzo[d][1,3]dioxol-5-yl)methyl)piperazin-1-yl)-1-cyclopropyl-1,4-dihydro-6-nitro-4-oxoquinotine-3-carboxylic acid (8c) was found to be the most active compound in vitro with MIC of 0.08 and 0.16 mu M against MTB and MDR-TB, respectively. In the in vivo animal model 8c decreased the bacterial load in lung and spleen tissues with 2.78 and 4.15-log 10 protections, respectively, at the dose of 50 mg/kg body weight.

  acids, designed by previous QSAR studies and characterized by an amino group at the C-6 position instead of the usual fluorine atom, were synthesized for the first time and evaluated for in vitro antibacterial activity. All of the synthesized compounds maintain good activity against Gram-negative bacteria (Pseudomonas aeruginosa excluded), and those compounds having a thiomorpholine group as the C-7 substituent
