A novel series of biaryl ether reverse hydroxamate MMP inhibitors has been developed. These compounds are potent MMP-2 inhibitors with limited activity against MMP-1. Select members of this series exhibit excellent pharmacokinetic properties with long elimination half-lives (7 h) and high oral bioavailability (100%).
A series of non-amide-linked 6-substituted-2-naphthamidine urokinase plasminogen activator (uPA) inhibitors are described. These compounds possess excellent binding activities and selectivities with significantly improved pharmacokinetic profiles versus previously described amide-linked inhibitors.
Further structure-activity relationships (SAR) for a novel dipeptide series inhibitors are reported. These inhibitors retain the Phe8-His9 portion of angiotensinogen and employ a unique Leu10-Val11 replacement [(LVR), ref 2]. SAR at the Leu10 side chain revealed that the LVR derived from cyclohexylalanine provided a nearly 10-fold boost in potency for the… (More)
Modification of the biphenyl portion of MMP inhibitor 2a gave analogue 2i which is greater than 1000-fold selective against MMP-2 versus MMP-1. The stereospecific synthesis of both enantiomers of 2i was achieved beginning with (S)- or (R)-benzyl glycidyl ether. The (S)-enantiomer, 11 (ABT-770), is orally bioavailable and efficacious in an in vivo model of… (More)
Representative nonsteroidal anti-inflammatory drug (NSAID) cyclooxygenase inhibitors such as ibuprofen, naproxen, and indomethacin were used as orally bioavailable scaffolds to design selective 5-lipoxygenase (5-LO) inhibitors. Replacement of the NSAID carboxylic acid group with a N-hydroxyurea group provided congeners with selective 5-LO inhibitory… (More)
A novel series of renin inhibitors based on the Phe8-His9-Leu10-Val11 substructure of renin's natural substrate, angiotensinogen, is reported. These inhibitors retain the Phe8-His9 portion of the native substructure and employ novel phosphostatine Leu10-Val11 replacements (LVRs). The phosphostatine LVRs were prepared by condensing a dialkyl phosphonate… (More)
A series of low-nanomolar renin inhibitors containing novel C-terminal heterocycles has been designed by formally cyclizing the C-terminus of a glycol-based inhibitor to the second hydroxyl. Molecular modeling suggests that the heterocyclic oxygen hydrogen bonds as an acceptor to the flap region of renin and that the second hydroxyl in the glycol-based… (More)
Stereoselective syntheses of several nonpeptide sulfidoethanol fragments that function as Leu10-Val11 (P1-P1') scissile bond replacements in human angiotensinogen are presented. These fragments are prepared from a variety of amino acids with formal P1 side chains varying in size and lipophilicity by converting them to their corresponding N-protected… (More)
