  摘要：

  We designed and synthesized a series of highly water-soluble prodrugs of an HIV protease inhibitor, KNI-727 (1), containing tandem-linked two auxiliary units, a solubilizing moiety and a self-cleavable spacer. Prodrugs with an ionized amino group at the solubilizing moiety exhibited a remarkable increase of water-solubility (>10(4) fold) compared to the parent drug 1. These prodrugs released 1 not enzymatically, but chemically via an intramolecular cyclization-elimination reaction through an imide formation in physiological conditions. Diversified rates of parent drug release were observed when the chemical structure of both the solubilizing and the spacer moieties were modified. This new approach for water-soluble prodrugs will enable to control chemically the release of parent drug as well as to maintain high water-solubility. (C) 2001 Elsevier Science Ltd.

  We designed and synthesized a series of water-soluble prodrugs of the HIV-1 protease inhibitor KNI-727 (1), which is a sparingly water-soluble drug with a water solubility of 5.5 mug/mL. These prodrugs, which contain a water-soluble auxiliary with two tandem-linked units, i.e., a self-cleavable spacer and a solubilizing moiety with an ionized amino function, exhibited a marked increase in water solubility (>10(4)-fold) compared with the parent drug 1. The mechanism of conversion to the parent drug 1 is not enzymatic but through a chemical cleavage at the spacer via an intramolecular cyclization-elimination reaction through an imide formation under physiological conditions. To diversify the conversion time for the parent drug regeneration, chemical modification of the auxiliary was carried out focusing on the introduction of cyclic tertiary amines, which can modify the basicity and/or conformational flexibility of the terminal amino function at the solubilizing moiety, and the change in bond length, which can attenuate the five-membered ring intermediate formation in the cleavage. These newly synthesized water-soluble prodrugs exhibited a practical water solubility with values greater than 50 mg/mL and enabled the constant regeneration of the parent drug 1 with diversified conversion times ranging from 4 min to 34 h as t(1/2) values under physiological conditions. All the water-soluble prodrugs tested regenerated the parent drug 1 in vivo as well as in vitro. A clear increase in the gastrointestinal absorption was observed in prodrugs 8, 12, and 13 with bioavailability (BA) values of 23%, 26%, and 29%, respectively. These BA values were 1.5-1.9-fold higher than that in the administration of the parent drug 1 alone. Other prodrugs showed only a similar or decreased BA compared to the parent drug 1. From these results, we found that not only a high water solubility but also an appropriate conversion time of the prodrug with a relatively narrow limit of around 35 min via intraduodenal administration was necessary for significant improvement of the gastrointestinal absorption in water-soluble prodrugs based on the spontaneous chemical cleavage. This is the first successful water-soluble prodrug that suggests an increased BA value greater than the parent drug in HIV-1 protease inhibitors and is the first study to show the importance of optimal conversion time in water-soluble prodrugs. Consequently, a water-soluble strategy that can control the conversion time would be extensively applicable to improve the gastrointestinal absorption of sparingly water-soluble drugs. The present information is an intriguing discovery and is one of the key factors that will contribute to the future design of practical water-soluble prodrugs.
• ‘Double-drugs’— A new class of prodrug form of an HIV protease inhibitor conjugated with a reverse transcriptase inhibitor by a spontaneously cleavable linker

  We designed and synthesized a new series of prodrug-type anti-HIV agents consisting of a peptidomimetic HIV protease inhibitor conjugated with a nucleoside reverse transcriptase inhibitor in an effort to enhance the antiviral activity. For the conjugation, a series of linkers that conjoin the two different classes of inhibitors have been investigated. Conjugates using a succinyl amino acid linker were shown to release the parent components via the spontaneous imide formation at a faster rate compared to conjugates using a glutaryl amino acid linker, as expected from the energetically favorable cyclization to the five-membered ring. Herein, we report a new 'double-drug' 4b (KNI-1039) with a glutarylglycine linker, which exhibited extremely potent anti-HIV activity compared with that of the individual components.
