Discovery of CGS 27023A, a Non-Peptidic, Potent, and Orally Active Stromelysin Inhibitor That Blocks Cartilage Degradation in Rabbits
摘要:
Structure-activity relationships of a lead hydroxamic acid inhibitor of recombinant human stromelysin were systematically defined by taking advantage of a concise synthesis that allowed diverse functionality to be explored at each position in a template. An ex vivo rat model and an in vivo rabbit model of stromelysin-induced cartilage degradation were used to further optimize these analogs for oral activity and duration of action. The culmination of these modifications resulted in CGS 27023A, a potent, orally active stromelysin inhibitor that blocks the erosion of cartilage matrix.

On the basis of an earlier observation that the N1-ethyl derivative of the hypoglycemic agent chlorpropamide (CP) inhibited aldehyde dehydrogenase (AlDH) in rats without producing hypoglycemia, we undertook a structure-activity study to assess the effect of altering the alkyl substituents at N1 and N3, as well as substituting O for N at the latter position, and evaluated these analogues for their effect on AlDH in vivo and in vitro. Our results suggest that only those CP analogues that can release alkyl isocyanates nonenzymatically inhibited AlDH. Increasing the steric bulk of the N1-alkyl substituent enhanced isocyanate formation and AlDH inhibition. CP analogues that lacked the NH group at N3 or were otherwise incapable of alkyl isocyanate release were inactive.
