    Optimization of a Potent, Orally Active S1P1 Agonist Containing a Quinolinone Core
    摘要:
    The optimization of a series of SIP, agonists with limited activity against S1P(3) is reported. A polar headgroup was used to improve the physicochemical and pharmacokinetic parameters of lead quinolinone 6. When dosed orally at 1 and 3 mg/kg, the azahydroxymethyl analogue 22 achieved statistically significant lowering of circulating blood lymphocytes 24 h postdose. In rats, a dose-proportional increase in exposure was measured when 22 was dosed orally at 2 and 100 mg/kg.

    摘要:
    人类非洲锥虫病(HAT)是一种主要的热带疾病,几乎没有可用于治疗的药物,从而推动了对新型活性化合物的需求。最近,氟喹诺酮类抗生素的吗啉代取代的苄基酰胺被确定为对布鲁氏锥虫具有高活性的化合物。由于先导化合物GHQ168在先前的试验中受到水溶性差的挑战,因此本研究的目的是引入结构变异性GHQ168以及配制GHQ168的最终目的是增加其水溶性,同时保持其体外抗锥虫活性。喷雾干燥的GHQ168以及新合成的化合物GHQ242和GHQ243在小鼠体内的药代动力学参数的特征是消除半衰期为1.5到3。腹膜内给药5小时后(4只小鼠/化合物),人血清白蛋白对GHQ168(80%)和GHQ243(45%)的结合具有中等至强的结合力,而GHQ242对人血清白蛋白的结合非常高(> 99%)。对于铅化合物GHQ168,表观清除率为112 ml / h,表观分布体积为14升/ kg体重(BW)。感染了T的小鼠。b。在严

  • Pyridone-carboxylic acids as antibacterial agents. I. Synthesis and antibacterial activity of 1-alkyl-1,4-dihydro-4-oxo-1,8- and 1,6-naphthyridine-3-carboxylic acids.

    Condensation of 2-amino-6-chloropyridine (1) with diethyl ethoxymethylenemalonate gave the aminomethylenemalonate 2, which upon thermal cyclization (Gould-Jacobs reaction) afforded ethyl 7-chloro-1, 4-dihydro-4-oxo-1, 8-naphthyridine-3-carboxylate (3). Alkylation of 3 produced the 1-alkyl derivative 4. Substitution of 4 with a cyclic amine gave ethyl 7-substituted 1-alkyl-1, 4-dihydro-4-oxo-1, 8-naphthyridine-3-carboxylate (5). The ester 5 was hydrolyzed to the corresponding carboxylic acid 6. 7-Substituted 1-alkyl-1, 4-dihydro-4-oxo-1, 6-naphthyridine-3-carboxylic acids (20) were also synthesized from 4-amino-2-chloropyridine (13) in a similar manner. The in vitro antibacterial activity was enhanced by the presence of a cyclic amine at position 7 on 6 and 20. In general, the 1, 8-naphthyridine 6 was more active than the 1, 6-naphthyrdine counterpart 20. 1-Ethyl-1, 4-dihydro-4-oxo-7-(1-piperazinyl)-1, 8-naphthyridine-3-carboxylic acid (6e) (an analog of both pipemidic acid and nalidixic acid) was comparable to pipemidic acid but superior to nalidixic acid in terms of activity in vitro against Pseudomonas aeruginosa.
    2-氨基-6-氯吡啶(1)与乙二醇乙氧基亚甲基丙二酸酯反应生成胺亚甲基丙二酸盐(2),进一步热环化(Gould-Jacobs反应)得到乙基7-氯-1,4-二氢-4-氧-1,8-萘啶-3-羧酸酯(3)。对3进行烷基化反应生成1-烷基衍生物(4)。用环胺取代4得到乙基7-取代的1-烷基-1,4-二氢-4-氧-1,8-萘啶-3-羧酸酯(5)。酯5水解得到相应的羧酸(6)。7-取代的1-烷基-1,4-二氢-4-氧-1,6-萘啶-3-羧酸(20)也以类似方式从4-氨基-2-氯吡啶(13)中合成。在6和20的7位引入环胺可增强其体外抗菌活性。通常情况下,1,8-萘啶(6)的活性优于1,6-萘啶(20)。1-乙基-1,4-二氢-4-氧-7-(1-哌嗪基)-1,8-萘啶-3-羧酸(6e)(是一种匹匹酸和那吡酸的类药物)在体外对铜绿假单胞菌的活性与匹匹酸相当,但优于那吡酸。
