  Biological activities and quantitative structure-activity relationships of spiro[imidazolidine-4,4'(1'H)-quinazoline]-2,2',5(3'H)-triones as aldose reductase inhibitors

  摘要：

  A series of spiro[imidazolidine-4,4'(1'H)-quinazoline]-2,2',5(3'H)-triones were prepared and tested for aldose reductase inhibitory activity. The 6'-halogenated derivatives were found to be highly potent in vitro inhibitors of male rabbit lens aldose reductase and in vivo inhibitors of polyol accumulation in the sciatic nerves of galactosemic rats. Of these, (4R)-6'-chloro-3'-methylspiro[imidazolidine-4,4'(1'H)-quinazoline]-2,2',5(3'H)-trione (67) showed the most potent in vitro and in vivo activities. An oral dose of 3 g/kg of compound 67 caused neither death nor behavioral abnormality in the preliminary acute toxicity study using mice and rats. Compound 67 was selected as a candidate for further evaluation. The quantitative structure-activity relationships in this series are also discussed.

  An aniline is converted to a 3-lower hydrocarbonthiooxindole by processes already known in the art and then air oxidized in an inert liquid vehicle in the presence of a base. The inert liquid vehicle advantageously is aprotic and the base is non-nucleophilic. Also, the aprotic liquid vehicle is desirably solvent for the starting 3-lower hydrocarbonthiooxindole and the non-nucleophilic base.

  一种苯胺经过已知的方法转化为3-较低碳氢硫代吲哚，然后在惰性液体载体中，在碱的存在下进行空气氧化。惰性液体载体有利于无质子性，碱是非亲核的。此外，无质子液体载体最好是起始3-较低碳氢硫代吲哚和非亲核碱的溶剂。
• Design, Synthesis, and Structure–Activity Relationship Studies of Tryptanthrins As Antitubercular Agents

  The natural product tryptanthrin (la) represents a potential lead for new tuberculosis (TB) drugs since tryptanthrin and its synthetic analogues possess potent in vitro activity against Mycobacterium tuberculosis (Mtb). However, in spite of their in vitro activity, none of these agents have been shown to be efficacious in vivo against animal models of TB. Described herein are syntheses of new tryptanthrin analogues together with a systematic investigation of their in vitro antitubercular activity and ADME properties followed by pharmacokinetic characterization in rodents for the most promising compounds. Those with the best potency and oral bioavailability were progressed to evaluations of efficacy against acute murine TB. The work aimed to prove the concept that this compound class can limit growth of Mtb during infection as well as to establish the SAR for in vitro activity against Mtb and the range of in vitro ADME parameters for this class of natural products. Novel C-11-deoxy (5b) and A-ring-saturated (6) tryptanthrin analogues were discovered that maintained activity against Mtb and showed improved solubility compared to tryptanthrin as well as evidence of oral bioavailability in rodents. However, neither 5b nor 6 demonstrated efficacy against acute murine TB following administration at doses up to 400 mg/kg daily for 4 weeks. Although 5b and 6 failed to inhibit replication or kill Mtb in vivo, they illuminate a path to new structural variations of the tryptanthrin scaffold that may maximize the potential of this class of compounds against TB.
