Inhibiting metalloproteases with PD 166793 in heart failure: impact on cardiac remodeling and beyond.[Pubmed:18466418]

Cardiovasc Ther. 2008 Spring;26(1):24-37.

Metalloproteinases (MMPs, also called matrixins) are extracellular proteolytic enzymes involved in the degradation of both matrix and nonmatrix proteins. Currently, 25 MMPs have been identified in humans, and the overexpression of one or more MMPs has been implicated in several pathologies, spanning from cancer to rheumathoid arthritis to cardiovascular disease. While research over the past 20 years has focused on understanding MMP biology and selectively inhibiting MMP activity, key issues that remain to be addressed include MMP roles in the context of normal versus pathological conditions and whether globally inhibiting MMPs improves or deteriorates overall organ function. In terms of cardiovascular disease, increased MMP expression has been demonstrated in the setting of myocardial ischemia, reperfusion injury, and during the progression to congestive heart failure. MMPs are also major contributors to the progression of atherosclerotic lesions. In this review, we focus on cardiovascular effects produced by PD 166793, a wide-broad spectrum MMP inhibitor, originally developed by Parke-Davis (now Pfizer). We will briefly review its structure, mechanism of action, and inhibitory capacity. Finally, we will illustrate the cardiac contexts, both in vivo and in vitro, in which PD166793 administration has proven beneficial.

Effects of matrix metalloproteinase inhibition on ventricular remodeling due to volume overload.[Pubmed:11997287]

Circulation. 2002 Apr 23;105(16):1983-8.

BACKGROUND: Left ventricular (LV) hypertrophy and dilatation are important compensatory responses to chronic volume overload. Although LV function is initially preserved by these responses, the continued structural remodeling of the myocardium ultimately becomes maladaptive, leading to the development of heart failure. We have shown previously that increased myocardial matrix metalloproteinase (MMP) activity precedes LV dilatation induced by a chronic volume overload. Accordingly, this study focused on the effects of MMP inhibition therapy (PD 166793, 1 mg x kg(-1) x d(-1)) on LV size and function in a rat model of volume overload-induced heart failure. METHODS AND RESULTS: Rats were divided into the following groups: treated and untreated infrarenal abdominal aortocaval fistula and treated and untreated sham-operated (control). LV weights of both fistula groups were increased above that of the control group (868+/-79 mg; P< or =0.001); LV weights in the treated fistula group, however, were lower than in the untreated fistula group at 8 weeks (1447+/-186 versus 1715+/-279 mg, respectively; P< or =0.012). The marked ventricular dilatation seen in the untreated fistula group was significantly diminished in the treated fistula group, although the increase in LV compliance was similar in both treated and untreated fistula hearts. CONCLUSIONS: MMP inhibition significantly attenuates the myocardial remodeling associated with chronic volume overload, as evidenced by prevention of dilatation, a marked reduction in LV hypertrophy, and preservation of ventricular function.

Matrix metalloproteinase inhibition attenuates left ventricular remodeling and dysfunction in a rat model of progressive heart failure.[Pubmed:11342481]

Circulation. 2001 May 8;103(18):2303-9.

BACKGROUND: Matrix metalloproteinase (MMP) activation contributes to tissue remodeling in several disease states, and increased MMP activity has been observed in left ventricular (LV) failure. The present study tested the hypothesis that MMP inhibition would influence LV remodeling and function in developing LV failure. METHODS AND RESULTS: LV size and function were measured in 5 groups of rats: (1) obese male spontaneously hypertensive heart failure rats (SHHF) at 9 months (n=10), (2) SHHF at 13 months (n=12), (3) SHHF rats treated with an MMP inhibitor during months 9 to 13 (PD166793 5 mg. kg(-1). d(-1) PO; n=14), (4) normotensive Wistar-Furth rats (WF) at 9 months (n=12), and (5) WF at 13 months (n=12). Plasma concentrations of the MMP inhibitor (116+/-11 micromol/L) reduced in vitro LV myocardial MMP-2 activity by approximately 100%. LV function and geometry were similar in WF rats at 9 and 13 months. LV peak +dP/dt was unchanged at 9 months in SHHF but by 13 months was reduced in the SHHF group compared with WF (3578+/-477 versus 5983+/-109 mm Hg/s, P

Structure-activity relationships and pharmacokinetic analysis for a series of potent, systemically available biphenylsulfonamide matrix metalloproteinase inhibitors.[Pubmed:10649971]

J Med Chem. 2000 Jan 27;43(2):156-66.

A series of biphenylsulfonamide derivatives of (S)-2-(biphenyl-4-sulfonylamino)-3-methylbutyric acid (5) were prepared and evaluated for their ability to inhibit matrix metalloproteinases (MMPs). For this series of compounds, our objective was to systematically replace substituents appended to the biphenyl and alpha-position of 5 with structurally diverse functionalities to assess the effects these changes have on biological and pharmacokinetic activity. The ensuing structure-activity relationship (SAR) studies showed that biphenylsulfonamides substituted with bromine in the 4'-position (11c) significantly improved in vitro activity and exhibited superior pharmacokinetics (C(max), t(1/2), AUCs), relative to compound 5. Varying the lipophilicity of the alpha-position by replacing the isopropyl group of 11c with a variety of substituents, in general, maintained potency versus MMP-2, -3, and -13 but decreased the oral systemic availability. Subsequent evaluation of its enantiomer, 11c', showed that both compounds were equally effective MMP inhibitors. In contrast, the corresponding hydroxamic acid enantiomeric pair, 16a (S-isomer) and 16a' (R-isomer), stereoselectivity inhibited MMPs. For the first time in this series, 16a' provided nanomolar potency against MMP-1, -7, and -9 (IC(50)'s = 110, 140, and 18 nM, respectively), whereas 16a was less potent against these MMPs (IC(50)'s = 24, 78, and 84 microM, respectively). However, unlike 11c, compound 16a' afforded very low plasma concentrations following a single 5 mg/kg oral dose in rat. Subsequent X-ray crystal structures of the catalytic domain of stromelysin (MMP-3CD) complexed with inhibitors from closely related series established the differences in the binding mode of carboxylic acid-based inhibitors (11c,c') relative to the corresponding hydroxamic acids (16a,a').
