  Novel type of plasmin inhibitors: Providing insight into P4 moiety and alternative scaffold to pyrrolopyrimidine

  摘要：

  Here we report a series of plasmin inhibitors which were originally derived from the parent structure of 1 and 2. Our efforts focused on the optimization of the P4 moiety of 2 and on the quest of alternative scaffold to pyrrolopyrimidine in the parent compounds. The results of the former gave us pivotal information on the further optimization of the P4 moiety in plasmin inhibitors and those of the latter revealed that appropriate moieties extending from the benzimidazole scaffold engaged with S4 pocket in the active site of plasmin.

  Pyrrolopyrimidine-inhibitors with hydantoin moiety as spacer can explore P4/S4 interaction on plasmin

  摘要：

  In the development of plasmin inhibitors, a novel chemotype, pyrrolopyrimidine scaffold possessing two motifs, a hydantoin-containing P4 moiety and a warhead-containing P1 moiety, is uncovered. A unique feature of the new line of the plasmin inhibitors is that the interaction between the plasmin inhibitors and key subsites in plasmin can be controlled by a spacer like hydantoin. The application of the novel chemotype is demonstrated by 1n and provides further evidence on the importance of hydantoin as the spacer. (c) 2014 Elsevier Ltd. All rights reserved.

  In this letter we report the design and synthesis of a series of plasmin inhibitors, which share the amino acid-based linker with limited free rotation between the hydantoin moiety and the benzimidazole scaffold. Our studies led to potent plasmin inhibitors and yielded important new insights into their structure-activity relationship for binding to the active site of plasmin. (C) 2016 Elsevier Ltd.
