  Structure-Based Design of Nonpeptidic HIV Protease Inhibitors from a Cyclooctylpyranone Lead Structure

  摘要：

  Recently, the novel cyclooctylpyranone HIV protease inhibitor 1 was identified in our labs, and an X-ray structure of this inhibitor complexed with HIV-2 protease was obtained. This crystal structure was used to develop two strategies for creating derivatives of 1 with enhanced enzyme inhibitory activity. The first strategy, substitution on the cyclooctyl ring, met with limited success, but provided some interesting information about the conformationally-flexible cyclooctyl ring on the inhibitors. The second strategy, substitution at the meta position of the aryl ring, was far more successful and generated compounds, such as the carboxamide derivatives 41 (K-i = 3.0 +/- 0.4 nM) and 36 (K-i = 4.0 +/- 0.8 nM), which were significantly more active than the corresponding unsubstituted cyclooctylpyranone 2 (K-i = 11.7 +/- 4.7 nM). An X-ray crystal structure of 36 complexed with HIV-1 protease indicated the increase in binding affinity is most likely due to the additional interactions between the amide substituent and the S3 region of the protease.

  Use of Medium-Sized Cycloalkyl Rings To Enhance Secondary Binding: Discovery of a New Class of Human Immunodeficiency Virus (HIV) Protease Inhibitors

  摘要：

  A unique strategy for the enhancement of secondary binding of an inhibitor to an enzyme has been demonstrated in the design of new human immunodeficiency virus (HIV) protease inhibitors. When the planar benzene ring of a 4-hydroxycoumarin lead compound (1a, K-1 = 0.800 mu M) was replaced with medium-sized (i.e., 7-9), conformationally-flexible, alkyl rings, the enzyme inhibitory activity of the resulting compounds was dramatically improved, and inhibitors with more than 50-fold better binding (e.g., 5d, K-i = 0.015 mu M) were obtained. X-ray crystal structures of these inhibitors complexed with HIV protease indicated the cycloalkyl rings were able to fold into the S1' pocket of the enzyme and fill it much more effectively than the rigid benzene ring of the 4-hydroxycoumarin compound. This work has resulted in the identification of a promising lead structure for the design of potent, deliverable HIV protease inhibitors. Compound 5d, a small (MW = 324), nonpeptidic structure, has already shown several advantages over peptidic inhibitors, including high oral bioavailability (91-99%), a relatively long half-life (4.9 h), and ease of synthesis (three steps).
