    • The invention provides prodrugs of DNA-reactive analogs of duocarmycin and CC-1065 anticancer agents, wherein a cyclic prodrug form, such as carbamate, thionocarbamate, or carbamimidate, can be hydrolyzed by the patient in vivo to yield a respective bioactive agent comprising a DNA-alkylating moiety and a binding/targeting moiety. The DNA-reactive moiety is a γ-spirocyclohexenone fused to a heterocyclyl group which can be produced by endogenous hydrolysis of a cyclic carbamate prodrug of the invention. The cyclic carbamate prodrug produces no residual byproduct during activation in vivo . Methods of synthesis and biological methods and data are also provided.
    • 本发明提供了杜卡霉素和CC-1065抗癌剂的DNA反应性类似物的前药,其中环状前体药物形式如氨基甲酸酯,硫代氨基甲酸酯或氨基甲酰亚胺酯可以在体内由患者水解,得到包含DNA的相应生物活性剂 - 烷基化部分和结合/靶向部分。 DNA反应性部分是与可以通过本发明的环状氨基甲酸酯前药的内源性水解产生的杂环基团融合的γ-螺环烯酮酮。 环状氨基甲酸酯前体体在体内活化期间不产生残留副产物。 还提供了合成方法和生物学方法和数据。

    • The invention is directed to glycopeptide antibiotics and their aglycones that are engineered to overcome bacterial resistance by replacement of a single, specific peptide carboxamide group in the core peptide of the glycopeptide antibiotic with an amidine group. The amidine pseudopeptide analog of the glycopeptide is effective in killing vancomycin-resistant bacteria at therapeutically achievable concentrations in a patient. For example, a [ψ[C(=NH)NH]Tpg 4 ]-vancomycin aglycon designed to exhibit the dual binding to D-Ala-D-Ala and D-Ala-D-Lac needed to reinstate activity against vancomycin-resistant bacteria has been shown to overcome a common mode of bacterial resistance to the "last resort" antibiotics of the glycopeptide class. The pseudopeptide amidine analogs can be prepared from corresponding pseudopeptide thioamide analogs, which can be prepared synthetically, semi-synthetically, or biosynthetically.
    • 本发明涉及通过用脒基取代糖肽抗生素的核心肽中的单个特异性肽羧酰胺基而被工程化以克服细菌耐药性的糖肽抗生素及其糖苷配基。 糖肽的脒假肽类似物在患者中以治疗可达到的浓度杀死万古霉素抗性细菌是有效的。 例如,设计用于显示与D-Ala-D-Ala和D-Ala-D-Lac的双重结合的[α[C(= NH)NH] Tpg4] - 万古霉素糖苷配基需要恢复对万古霉素抗性细菌的活性 已被证明能够克服对糖肽类的“最后手段”抗生素的细菌耐药性的共同模式。 假肽脒类似物可以由相应的假肽硫代酰胺类似物制备,其可以合成,半合成或生物合成制备。
