None:
A structure-activity/structure-property relationship study based on the physicochemical as well as in vitro pharmacokinetic properties of a first generation matrix metalloproteinase (MMP)-13 inhibitor (2) was undertaken. After systematic variation of inhibitor 2, compound 31 was identified which exhibited microsomal half-life higher than 20 min, kinetic solubility higher than 20 microM, and a permeability coefficient greater than 20 × 10-6 cm/s. Compound 31 also showed excellent in vivo PK properties after IV dosing (Cmax = 56.8 microM, T1/2 (plasma) = 3.0 h, Cl = 0.23 mL/min/kg) and thus is a suitable candidate for in vivo efficacy studies in an OA animal model.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
