Identification and Initial Structure−Activity Relationships of a Novel Class of Nonpeptide Inhibitors of Blood Coagulation Factor Xa
摘要:
The discovery and some of the basic structure-activity relationships of a series of novel nonpeptide inhibitors of blood coagulation Factor Xa is described. These inhibitors are functionalized p-alanines, exemplified by 2a. Docking experiments placing 2a in the active site of Factor Xa implied that the Most expeditious route to enhancing in vitro potency was to modify the group occupying the S3 site of the enzyme. Increasing the hydrophobic contacts between the inhibitor and the enzyme in this region led to 8, which has served as the prototype for this series. In addition, an enantioselective synthesis of these substituted p-alanines was also developed.
A benzoheterocyclic derivative of the following formula [1]:
and pharmaceutically acceptable salts thereof, which show excellent anti-vasopressin activity, vasopressin agonistic activity and oxytocin antagonistic activity, and are useful as a vasopressin antagonist, vasopressin agonist or oxytocin antagonist.

New types of resorcinarene-based nanoscale container molecules 2 and 3 are described. They feature reversibly folding unimolecular cavities of nanoscaledimensions and ∼800 A3 internal volume; they are among the largest synthetic unimolecular hosts prepared to date. Two seams of intramolecular hydrogen bonds, provided by 12 secondary amides, control the guest uptake and release. The hydrogen bonds

A pseudo-esterase activity-based fluorescent probe for specific detection of albumin, which has a carboxylic ester bond that can be selectively cleaved by human serum albumin (HSA), therefore forming a hydrolysate, which has a fluorescence emission spectrum significantly different from that of the fluorescent probe. According to the fluorescence intensity of the fluorescent probe and hydrolysate, we can detect the content of HSA in a biological sample.
