  Synthesis and Cytotoxic Activities ofα-Methylidene-γ-butyrolactones Bearing a Quinolin-4(1H)-one Moiety

  摘要：

  The cytotoxicities of the u-methylidene-gamma -butyrolactones 4. 5. and 8. which are linked to a quinolin-4(1H)-one moiety through a piperazine or O-atom bridge were studied. These compounds were synthesized by alkylation of 1-ethyl-6-fluoro-1,4-dihydro-7-hydroxy-4-oxoquinoline-3-carboxylic acid (6) followed by a Reformatsky-type condensation. Compounds 4. 5. and 8 were evaluated in vitro against 60 human-tumor cell lines derived from nine cancer-cell types and demonstrated not only strong growth-inhibitory activities against leukemia cancer cells. but also fairly good activities against the growth of certain solid tumors (see Table). The O-bridged derivatives 8a and 8b exhibit both cytostatic (mean log GI(50) = -5.20 and - 5.82, resp.) and cytocidal (mean log LC50 = - 4.30 and -4.93. resp.) effects, while the piperazine-bridged analogues 4 and 5 possess only weak cytostatic (mean log GI(50) = - 5.20 and -5.82, resp. mean log LC50 > -4.00) capability, among them. 8b is the most potent, with log GI(50) = -6.47. -6.72. -653, and 6.52 against leukemia. SW-620 (colon). Lox IMVI, and SK-MEL-28 (melanoma) cancer cells. respectively.

  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.

  Certain 1-ethyl- and 1-aryl-6-fluoro-1,4-dihydroquinol-4-one derivatives were synthesized and evaluated for antimycobacterial and cytotoxic activities. Preliminary results indicated that, for 1-aryl-6-fluoroquinolones, both 7-(piperazin-1-yl)- and 7-(4-methylpiperazin-1-yl) derivatives, 9b and 11a, are able to completely inhibit the growth of M. tuberculosis at a concentration of 6.25 μg/ml, while

  We report herein the synthesis and biological evaluation of two series of 7-substituted norfloxacin derivatives. Most compounds tested in this study demonstrated better activity against methicillin-resistant Staphylococcus aureus than norfloxacin. Preliminary in vitro evaluation indicated that the 7-[4-(2-hydroxyiminoethyl)piperazin-1-yl] derivatives 3b-e possess distinct cytotoxicity profiles as compared with their alpha-methylene-gamma-butyrolactone counterparts, 4b,e: i.e., excellent activities against the renal cancer subpanel. Among them, 1-ethyl-6-fluoro-7-4-[2-(4-chlorophenyl)-2-hydroxyiminoethyl]-1-piperazinyl}-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid (3d) demonstrated the most significant activities against renal cancer cell lines, with log GI(50) values of -6.40 against CAK-1, -6.14 against RXF 393, and -7.54 against UO-31, compared with a mean log GI(50) value of -5.03.
