  Synthesis and Structure−Activity Relationships of Novel 7-Substituted 1,4-Dihydro-4-oxo-1-(2-thiazolyl)-1,8-naphthyridine-3-carboxylic Acids as Antitumor Agents. Part 1

  摘要：

  In an attempt to search for clinically useful antitumor agents, we have discovered that a series of 1,1-disubstituted-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acids possessed moderate cytotoxic activity.,We investigated the structure-activity relationships in this series of compounds by changing N-1 and C-7 positions and the core ring structure itself and evaluated the synthesized compounds against several murine and human tumor cell lines. These modifications led us to the following findings. (1) The 2-thiazolyl group at the N-1 position of the naphthyridine structure is the best substituent for antitumor activity. (2) Regarding core ring structure, the naphthyridine derivative is the most active followed by pyridopyrimidine analogue. (3) At the C-7 position, -aminopyrrolidine derivatives are more effective than other amines or thioether derivatives. Finally, the trans-3-amino-4-methoxypyrrolidinyl derivative (43j), and the 3-amino-3-methylpyrrolidinyl derivative (43f) as well as 3-aminopyrrolidinyl derivative (AT-3639, 1) were determined to be effective in in vitro and in vivo antitumor assays, and their activity was comparable to that of etoposide.

  1-substituted 7-[3-[(ethylamino)methyl]-1- pyrrolidinyl]-6,8-difluoro-1,4-dihydro-4-oxo-3-quinoline- carboxylic acids (N1 analogues of CI-934) were synthesized and evaluated for antibacterial activity and DNA-gyrase inhibition. Correlations between the inhibition of DNA gyrase and antibacterial potency were established. A quantitative structure-activity relationship (QSAR) was derived by using the

  一系列18个1-取代的7- [3-[（[乙基氨基）甲基] -1-吡咯烷基] -6,8-二氟-1,4-二氢-4-氧代-3-喹啉-羧酸（N1类似物合成CI-934）并评估其抗菌活性和DNA回转酶抑制作用。建立了DNA促旋酶抑制作用与抗菌能力之间的关系。通过使用11种细菌菌株的抗菌能力和革兰氏阴性平均值得出定量构效关系（QSAR）。该方程式表明，抗菌效力在很大程度上取决于STERIMOL的长度和宽度以及N1取代基的不饱和度。一些菌株还显示出对N1组中杂原子（O，N，S）的依赖性。旋回酶抑制与这些参数的组合之间没有发现显着的相关性。结合分子建模研究的构象分析，讨论了这些QSAR结果。在所有方面，最能提高喹诺酮活性的取代基是环丙基。该类似物1-环丙基-7- [3-[（[乙基氨基）-甲基] -1-吡咯烷基] -6，8-二氟-1,4-二氢-4-氧代-3-喹啉羧酸（PD 117558），与相关标准相比，在体外和体内均具有出色的广谱活性。

  N-Benzyl-3-bromoazetidine (13), which was obtained by the reaction of ABB (3) with benzyl bromide, gave 3-aliphatic amino-substituted azetidine derivatives 15a, b. Novel fluoroquinolones 7a-f, 11a-f, 16a, b and 25a-c were obtained by the introduction of these azetidine derivatives into the C7 position of a quinolone nucleus 6 and N1-heterocyclic quinolones 21a-c in 21-83% yields.
