  Discovery, SAR, synthesis, pharmacokinetic and biochemical characterization of A-192411: A novel fungicidal lipopeptide-(I)

  摘要：

  The echinocandin class of cyclic lipopepetides has been simplified to discover potent antifungal compounds. Namely A-192411 shows good in vitro activity against common pathogenic yeasts and has an acceptable safety window in vivo. Discovery, limited SAR, synthesis, biochemical and pharmaco-dynamic profiles of A-192411 are presented. (C) 2002 Elsevier Science Ltd. All rights reserved.

  Novel backbone-cyclized peptidomimetics of the general formula cyclo[-P1-P2-P3-P4-P5-P6-P7-P8-T1-T2-] (I) wherein the single elements T or P are α-amino acid residues connected in either direction which, depending on their positions in the chain, are as defined in the description and the claims, and salts thereof, have the property to modulate the GLP-1 receptor. They can be used as medicaments to treat, prevent, or delay the onset of diseases, disorders or conditions in which modulation of the human GLP-1 receptor is beneficial, such as type 2 diabetes. These backbone-cyclized peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.

  fungal infections continues to rise. Naturally occurring hexapeptide echinocandin B (1) has shown potent antifungal activity via its inhibition of the synthesis of beta-1,3 glucan, a key fungal cell wall component. Although this series of agents has been limited thus far based on their physicochemical characteristics, we have found that the synthesis of analogues bearing an aminoproline residue in the

  Reactions involving phenol derivatives and acyl chlorides have to be controlled for competitive O-acylations and C-acylations (Friedel–Crafts acylations and Fries rearrangements) in acidic condition. The extent for these reactions in trifluoromethanesulfonic acid (TfOH), which is used as catalyst and solvent, is examined. Although diluted TfOH was needed for effective O-acylation, concentrated TfOH

  对于酸性条件下的竞争性O-酰化和C-酰化（Friedel-Crafts酰化和Fries重排），必须控制涉及酚衍生物和酰氯的反应。检查了在用作催化剂和溶剂的三氟甲磺酸（TfOH）中这些反应的程度。尽管有效的O-酰化需要稀释的TfOH，但在温和的条件下有效的C-酰化则需要浓缩的TfOH。这些结果已应用于新的高酪氨酸衍生物的合成。N -TFA–Asp（OBn）–OMe的弗里斯重排和苯酚与N的Friedel-Crafts酰化反应TfOH中的-TFA–Asp（Cl）–OMe提供高酪氨酸骨架，然后还原和脱保护得到高酪氨酸，以光学纯净形式保留Asp的立体化学。
