Indole Inhibitors of Human Nonpancreatic Secretory Phospholipase A2. 2. Indole-3-acetamides with Additional Functionality
摘要:
As reported in our previous paper, a series of indole-3-acetamides which possessed potency and selectivity as inhibitors of human nonpancreatic secretory phospholipase A(2)(hnps-PLA(2)) was developed. The design of these compounds was based on information derived from x-ray crystal structures determined for complexes between the enzyme and its inhibitors. We describe here the further implementation of this structure-based design strategy and continued SAR development to produce indole-3-acetamides with additional functionalities which provide increased interaction with important residues within the enzyme active site. These efforts led to inhibitors with substantially enhanced potency and selectivity.
A class of novel 1-indole-3-acetamides represented by the formula; ##STR1## is disclosed together with the use of such indole compounds for inhibiting sPLA.sub.2 mediated release of fatty acids.
A class of novel 1H-indole-3-acetamides is disclosed together with the use of such indole compounds for inhibiting sPLA2 mediated release of fatty acids for treatment of conditions such as septic shock.
