  Macrocyclic hydroxamate inhibitors of matrix metalloproteinases and TNF-α production

  摘要：

  Several macrocyclic, hydroxamate derivatives were synthesized and evaluated as inhibitors of matrix metalloproteinases (MMPs) and tumour necrosis factor-alpha (TNF-alpha) production. These macrocycles are anti-succinate based inhibitors linked from P1 to P2'. A variety of functionality was installed at the P1-P2' linkage, which gave inhibitors that displayed excellent MMP inhibition and good TNF-alpha suppression. (C) 1999 DuPont Pharmaceuticals Company.

  Design, Synthesis, and Structure−Activity Relationships of Macrocyclic Hydroxamic Acids That Inhibit Tumor Necrosis Factor α Release in Vitro and in Vivo

  摘要：

  To search for TNF-alpha (tumor necrosis factor alpha) converting enzyme (TACE) inhibitors, we designed a new class of macrocyclic hydroxamic acids by linking the PI and P2 ' residues of acyclic anti-succinate-based hydroxamic acids. A variety of residues including amide, carbamate, alkyl, sulfonamido, Boc-amino, and amino were found to be suitable P1-P2 ' linkers. With an N-methylamide at P3 ', the 13-16-membered macrocycles prepared exhibited low micromolar activities in the inhibition of TNF-alpha release from LPS-stimulated human whole blood. Further elaboration in the P3 ' -P4 ' area using the cyclophane and cyclic carbamate templates led to the identification of a number of potent analogues with IC50 values of less than or equal to 0.2 muM in whole blood assay (WBA). Although the P3 ' area can accommodate a broad array of structurally diversified functional groups including polar residues, hydrophobic residues, and amino and carboxylic acid moieties, in both the cyclophane series and the cyclic carbamate series, a glycine residue at P3 ' was identified as a critical structural component to achieve both good in vitro potency and good oral activity. With a glycine residue at P3 ', an N-methylamide at P4 ' provided the best cyclophane analogue, SL422 (WBA IC50 = 0.22 muM, LPS-mouse ED50 = 15 mg/kg, po), whereas a morpholinylamide at P4 ' afforded the most potent and most orally active cyclic carbamate analogue, SP057 (WBA IC50 = 0.067 muM, LPS-mouse ED50 = 2.3 mg/kg, po). Further profiling for SL422 and SP057 showed that these macrocyclic compounds are potent TACE inhibitors, with K-i values of 12 and 4.2 nM in the porcine TACE assay, and are broad-spectrum MMP inhibitors. Pharmacokinetic studies in beagle dogs revealed that SL422 and SP057 are orally bioavailable, with oral bioavailabilities of 11% and 23%, respectively.
