The design of potent and selective inhibitors of thrombin utilizing a piperazinedione template: Part 2
摘要:
Potent and selective thrombin inhibitors have been prepared with a piperazinedione template and L-amino acids. Likewise, incorporation of D-amino acids led to potent inhibitors with a novel mode of binding. Herein, the structure activity relationships and structural aspects of these compounds will be described. (C) 1999 Elsevier Science Ltd. All rights reserved.

Novel unnatural dipeptoids of .alpha.-substituted Trp-Phe derivatives useful as agents in the treatment of obesity, hypersecretion of gastric acid in the gut, gastrin-dependent tumors, or as antipsychotics are disclosed. Further the compounds are antianxiety agents, antiulcer agents, antidepressant agents, and are agents useful for preventing the withdrawal response produced by chronic treatment or use followed by chronic treatment followed by withdrawal from nicotine, diazepam, alcohol, cocaine, caffeine, or opiods. Also disclosed are pharmaceutical compositions and methods of treatment using the dipeptoids as well as processes for preparing them and novel intermediates useful in their preparation. An additional feature of the invention is the use of the subject compounds to prepare pharmaceutical and diagnostic compositions.
Hydroxamicacids are outstanding zinc chelating groups that can be used to design potent and selective metalloenzyme inhibitors in various therapeutic areas. Some hydroxamicacids display a high plasma clearance resulting in poor in vivo activity, though they may be very potent compounds in vitro. We designed a 57-member library of hydroxamicacids to explore the structure–plasma stability relationships

A range of α-amino esters can be turned into sulfonylhydantoins 2 in a single, atom-economic step using sulfamide and DBU. This procedure obviates the need for a three- or four-step sequence utilised by traditional procedures. Two new six-membered analogues 3 and 4 have also been prepared utilising novel synthetic protocols.

A new series of hydroxamic acid-based matrixmetalloproteinase (MMP) inhibitors containing a unique phosphinamide motif derived from D-amino acid was designed, synthesized, and tested for enzyme inhibition. Compounds with an R configuration at phosphorus were found to be potent MMP inhibitors while molecules with the S configuration were almost inactive. Structure-activity relationship studies of the
