Design and Synthesis of Renin Inhibitors: Incorporation of Transition-State Isostere Side Chains That Span from the S1 to the S3 Binding Pockets and Examination of P3-Modified Renin Inhibitors
摘要:
A series of renin inhibitors were designed to examine the topography of the contiguous binding pocket of renin that is normally occupied by the P1 and P3 side chains. Molecular modeling suggested that extending the P1 hydrophobic side chain into the adjacent hydrophobic S3 enzyme pocket was feasible. Novel transition state isosteres with modified P1-->P3 side chains were synthesized and provided enhanced binding affinity when incorporated into renin inhibitors in which the P3 Phe was substituted by Gly. In a complementary approach, the binding affinities of a variety of P3-P4-modified peptidomimetic renin inhibitors that lacked substantial hydrophobic side chains at these sites were measured.

Electrochemical biosensing devices and methods detect the activity of proteases and active infection in biological samples. The devices and methods utilize distance constraints between a redox reporter and an electrode to create a change in current that is detected. The distance constraints are released when an analyte containing a specified protease or proteases reacts with a protein substrate sequence in the analyte. The particular protease or proteases to be detected can be selected by using biosensors with particular substrate sequences. The devices and methods are not only qualitative, they can be used to quantitatively evaluate protease content in samples.
