The effect of zofenopril on the cardiovascular system of spontaneously hypertensive rats treated with the ACE2 inhibitor MLN-4760. Biol Res 2023; 56:55. [PMID: 37875978 PMCID: PMC10598995 DOI: 10.1186/s40659-023-00466-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 10/12/2023] [Indexed: 10/26/2023] Open
Abstract
BACKGROUND Angiotensin converting enzyme 2 (ACE2) plays a crucial role in the infection cycle of SARS-CoV-2 responsible for formation of COVID-19 pandemic. In the cardiovascular system, the virus enters the cells by binding to the transmembrane form of ACE2 causing detrimental effects especially in individuals with developed hypertension or heart disease. Zofenopril, a H2S-releasing angiotensin-converting enzyme inhibitor (ACEI), has been shown to be effective in the treatment of patients with essential hypertension; however, in conditions of ACE2 inhibition its potential beneficial effect has not been investigated yet. Therefore, the aim of the study was to determine the effect of zofenopril on the cardiovascular system of spontaneously hypertensive rats, an animal model of human essential hypertension and heart failure, under conditions of ACE2 inhibition induced by the administration of the specific inhibitor MLN-4760 (MLN). RESULTS Zofenopril reduced MLN-increased visceral fat to body weight ratio although no changes in systolic blood pressure were recorded. Zofenopril administration resulted in a favorable increase in left ventricle ejection fraction and improvement of diastolic function regardless of ACE2 inhibition, which was associated with increased H2S levels in plasma and heart tissue. Similarly, the acute hypotensive responses induced by acetylcholine, L-NAME (NOsynthase inhibitor) and captopril (ACEI) were comparable after zofenopril administration independently from ACE2 inhibition. Although simultaneous treatment with zofenopril and MLN led to increased thoracic aorta vasorelaxation, zofenopril increased the NO component equally regardless of MLN treatment, which was associated with increased NO-synthase activity in aorta and left ventricle. Moreover, unlike in control rats, the endogenous H2S participated in maintaining of aortic endothelial function in MLN-treated rats and the treatment with zofenopril had no impact on this effect. CONCLUSIONS Zofenopril treatment reduced MLN-induced adiposity and improved cardiac function regardless of ACE2 inhibition. Although the concomitant MLN and zofenopril treatment increased thoracic aorta vasorelaxation capacity, zofenopril increased the participation of H2S and NO in the maintenance of endothelial function independently from ACE2 inhibition. Our results confirmed that the beneficial effects of zofenopril were not affected by ACE2 inhibition, moreover, we assume that ACE2 inhibition itself can lead to the activation of cardiovascular compensatory mechanisms associated with Mas receptor, nitrous and sulfide signaling.

Abstract
Heart failure (HF) is a multifactorial clinical syndrome involving many complex processes. The causes may be related to abnormal heart structure and/or function. Changes in the renin-angiotensin-aldosterone system, the sympathetic nervous system, and the natriuretic peptide system are important in the pathophysiology of HF. Dysregulation or overexpression of these processes leads to changes in cardiac preload and afterload, changes in the vascular system, peripheral vascular dysfunction and remodeling, and endothelial dysfunction. One of the important factors responsible for the development of heart failure at the cellular level is oxidative stress. This condition leads to deleterious cellular effects as increased levels of free radicals gradually disrupt the state of equilibrium, and, as a consequence, the internal antioxidant defense system is damaged. This review focuses on pharmacotherapy for chronic heart failure with regard to oxidation-reduction metabolism, with special attention paid to the latest group of drugs, SGLT2 inhibitors-an integral part of HF treatment. These drugs have been shown to have beneficial effects by protecting the antioxidant system at the cellular level.

Abstract
Few millions of new cancer cases are diagnosed worldwide every year. Due to significant progress in understanding cancer biology and developing new therapies, the mortality rates are decreasing with many of patients that can be completely cured. However, vast majority of them require chemotherapy which comes with high medical costs in terms of adverse events, of which cardiotoxicity is one of the most serious and challenging. Anthracyclines (doxorubicin, epirubicin) are a class of cytotoxic agents used in treatment of breast cancer, sarcomas, or hematological malignancies that are associated with high risk of cardiotoxicity that is observed in even up to 30% of patients and can be diagnosed years after the therapy. The mechanism, in which anthracyclines cause cardiotoxicity are not well known, but it is proposed that dysregulation of renin-angiotensin-aldosterone system (RAAS), one of main humoral regulators of cardiovascular system, may play a significant role. There is increasing evidence that drugs targeting this system can be effective in the prevention and treatment of anthracycline-induced cardiotoxicity what has recently found reflection in the recommendation of some scientific societies. In this review, we comprehensively describe possible mechanisms how anthracyclines affect RAAS and lead to cardiotoxicity. Moreover, we critically review available preclinical and clinical data on use of RAAS inhibitors in the primary and secondary prevention and treatment of cardiac adverse events associated with anthracycline-based chemotherapy.

Abstract
Hypertension and kidney disease often coexist, further increasing the risk of future cardiovascular events. Treatment of hypertensive adults with an angiotensin converting enzyme inhibitor in case of concomitant kidney disease may slow disease progression. The third-generation liphophilic angiotensin converting enzyme inhibitor zofenopril, administered alone or combined with a thiazide diuretic, has proved to be effective in lowering blood pressure in hypertensive patients and to reduce the risk of fatal and non-fatal events in post-acute myocardial infarction and heart failure. In almost three-hundred hypertensive patients with kidney impairment zofenopril administered for 12 weeks showed a similar blood pressure-lowering effect irrespective of the stage of the disease, with larger effects in combination with a thiazide diuretic, particularly in patients with slightly or moderately impaired kidney function. In animal models, zofenopril produced a significant and long-lasting inhibition of kidney angiotensin converting enzyme inhibitor and prevented kidney morphological and functional alterations following kidney ischemia-reperfusion injury. Treatment of hypertensive patients for 18 weeks with a combination of zofenopril 30 mg and hydrochlorothiazide 12.5 mg resulted in a reduction in albumin creatinine ratio of 8.4 mg/g (49.6% reduction from baseline values) and no changes in glomerular filtration rate, variations in line with those obtained in the control group treated with a combination of irbesartan 150 mg and hydrochlorothiazide 12.5 mg. Thus, some preliminary evidence exists to support that relatively long-term treatment with the angiotensin converting enzyme inhibitor zofenopril alone or combined with hydrochlorothiazide is effective in controlling blood pressure and may confer some kidney protection due to ACE inhibition properties.

Abstract
SIGNIFICANCE Shortly after the discovery of the role of hydrogen sulfide (H2S) in many physiological and pathological processes, attempts were made to develop novel pharmaceuticals that may be of benefit for treatment or prevention of a wide range of disorders. The promise of H2S-based therapeutics is now being demonstrated in clinical trials. Recent Advances: H2S-releasing drugs, such as SG1002 for cardiovascular disorders, and ATB-346 for arthritis, have progressed into clinical trials and have shown considerable promise. Some older drugs, such as zofenopril, have now been recognized to produce at least some of the beneficial effects through release of H2S. CRITICAL ISSUES There remains a need to better understand the underlying mechanisms for some of the observed effects of H2S-releasing drugs in a clinical setting, such as the marked increase in analgesic potency that has been observed with ATB-346. FUTURE DIRECTIONS The proof-of-concept clinical studies reviewed herein pave the way for examination, in a clinical setting, of several other potential applications of H2S-based drugs in a wide range of disorders, including diabetes, hypertension, and cancer chemoprevention.

Abstract
Zofenopril is a lipophilic, sulfhydryl group-containing angiotensin-converting enzyme (ACE)-inhibitor, characterized by wide tissue distribution, long duration of action, and pleiotropic effects on endothelial dysfunction. Its clinical efficacy and safety have been described in the four randomized controlled trials of the SMILE program, which globally enrolled more than 3600 patients in post-acute myocardial infarction (AMI) setting. The SMILE-4 study specifically selected patients with left ventricular dysfunction at admission, and compared the effects of zofenopril or ramipril in combination with acetylsalicylic acid (ASA). Zofenopril demonstrated its superiority over ramipril in reducing the combined occurrence of death or hospitalization for cardiovascular causes both in the overall population included in the original study and in subgroups of patients at highest risk, namely hypertensive and diabetic subjects. The effects of the early treatment with zofenopril were sustained over time, and, after 5 years of follow-up, zofenopril increased the survival likelihood and reduced the hospitalization rate. Compared to ramipril, zofenopril was cost-effective with a number to treat of 13 and an incremental cost-effectiveness ratio (ICER) of 2125.45 euros for any additional event prevented. Furthermore, in real-world settings, zofenopril decreased the risk of death in patients with heart failure, particularly in men, and in subjects older than 76 years or with ejection fraction lower than 54%. These results support the early use of zofenopril immediately after AMI, even in the presence of comorbidities, and its maintenance over time to reduce the risk of heart failure.

Abstract
Diabetes mellitus is a chronic condition that continues to increase in both incidence and prevalence. Renin-Angiotensin-Aldosterone System is one of the main modulators of chronic hyperglycaemia and, thus, its influence on tissues. Hyperglycaemia-induced oxidative stress is an important factor in diabetic cardiomyopathy. The present study was carried out on 24 adult male Wistar albino rats (8-week-old and with body masses of 190 ± 10 g). We evaluated the influence of acute administration of zofenopril on ex vivo myocardial function from rats with streptozotocin-induced diabetes mellitus, with a special emphasis on cardiodynamic and oxidative stress parameters in diabetic rat hearts. Rats were divided randomly into two groups (12 animals per group): control non-diabetic animals (C) were healthy rats perfused with 1.5 µM of zofenopril, and STZ-treated diabetic animals (DM) were diabetic animals perfused with 1.5 µM of zofenopril 4 weeks after the induction of diabetes. Our results demonstrated that diabetic rats are characterized by a depressed cardiac performance and that oxidative markers are related to alterations in cardiac function in rats with 4 weeks of STZ-induced diabetes. Additionally, the use of zofenopril as a monotherapy slightly diminished cardiac damage induced by chronic hyperglycaemia. However, long-term follow-up intervention trials are necessary to fully demonstrate the benefit of zofenopril in this context. A challenge for future investigations will be to identify the effects of chronic administration or combination therapy with angiotensin-converting enzyme inhibitors in various models of diabetes.

Abstract
Zofenopril, a new potent sulphydryl angiotensin-converting enzyme (ACE) inhibitor, is characterized by high lipophilicity, selective cardiac ACE inhibition, and antioxidant and tissue protective activities. In vitro and in vivo experiments suggest that zofenopril exerts antioxidant properties at clinically achievable tissue concentrations. In endothelial cells, zofenopril enhances nitric oxide production, attenuates atherosclerotic lesion development and inhibits adhesion molecule expression by reducing reactive oxygen species. These peculiar characteristics are reflected in the drug's cardioprotective activity, which has been shown to be greater than that of non-sulphydryl ACE inhibitors. Cardiac hypertrophy was also reduced by chronic zofenopril administration, independently of its blood pressure-reducing effect. ACE inhibitors with a sulphydryl group could have an advantage in improving vascular function and reducing cardiac impairment compared with non-sulphydryl-containing ACE inhibitors. This could explain zofenopril's remarkable clinical efficacy post-infarction, and potentially beneficial use in prevention and therapy of cardiovascular diseases, such as atherosclerosis, thrombosis and heart failure.

Abstract
BACKGROUND AND PURPOSE Hydrogen sulfide (H2 S), an endogenous volatile mediator with pleiotropic functions, promotes vasorelaxation, exerts anti-inflammatory actions and regulates angiogenesis. Previously, the SH-containing angiotensin-converting enzyme inhibitor (ACEI), zofenopril, was identified as being effective in preserving endothelial function and inducing angiogenesis among ACEIs. Based on the H2 S donor property of its active metabolite zofenoprilat, the objective of this study was to evaluate whether zofenoprilat-induced angiogenesis was due to increased H2 S availability. EXPERIMENTAL APPROACH HUVECs were used for in vitro studies of angiogenesis, whereas the Matrigel plug assay was used for in vivo assessments. KEY RESULTS Zofenoprilat-treated HUVECs showed an increase in all functional features of the angiogenic process in vitro. As zofenoprilat induced the expression of CSE (cystathionine-γ-lyase) and the continuous production of H2 S, CSE inhibition or silencing blocked the ability of zofenoprilat to induce angiogenesis, both in vitro and in vivo. The molecular mechanisms underlying H2 S/zofenoprilat-induced angiogenesis were dependent on Akt, eNOS and ERK1/2 cascades. ATP-sensitive potassium (KATP ) channels, the molecular target that mediates part of the vascular functions of H2 S, were shown to be involved in the upstream activation of Akt and ERK1/2. Moreover, the up-regulation of fibroblast growth factor-2 was dependent on CSE-derived H2 S response to H2 S and KATP activation. CONCLUSIONS AND IMPLICATIONS Zofenoprilat induced a constant production of H2 S that stimulated the angiogenic process through a KATP channel/Akt/eNOS/ERK1/2 pathway. Thus, zofenopril can be considered as a pro-angiogenic drug acting through H2 S release and production, useful in cardiovascular pathologies where vascular functions need to be re-established and functional angiogenesis induced.

Abstract
BACKGROUND Persistent dry cough is a well known unwanted effect of Angiotensin-Converting Enzyme inhibitors (ACE-i). Animal studies have shown that the ACE-i zofenopril has a less tussigenic effect compared to the widely used ACE-i ramipril. The aim of this study was to compare cough sensitivity to inhaled tussigens, as well as spontaneous cough in response to the administration of zofenopril and ramipril in healthy volunteers; pharmacokinetic (PK) data of both zofenopril and ramipril, as well as their respective active forms, zofenoprilat and ramiprilat, was also collected. METHODS Forty healthy volunteers were enrolled in a randomized crossover study. Patients were administered zofenopril calcium salt (test drug) coated tablets, 30 mg daily dose or ramipril (reference drug) tablets, 10 mg daily dose, for 7 consecutive days in two periods separated by a 21-day wash-out period. Cough sensitivity to capsaicin and citric acid was assessed as the concentration of each tussigenic agent causing at least 2 (C2) or 5 coughs (C5); spontaneous cough was also monitored throughout the study. PK parameters of zofenopril, ramipril and their active forms, were collected for each of the two study periods. Airway inflammation, as assessed by fractional exhaled nitric oxide (FeNO) and bradykinin (BK) levels, were measured prior to and following each treatment period. RESULTS Ramipril, but not zofenopril, increased (p < 0.01) cough sensitivity to both tussigenic agents as assessed by C2. With citric acid, C5 values calculated after both ramipril and zofenopril administration were significantly (p < 0.05 and p < 0.01, respectively) lower than corresponding control values. With both ACE-i drugs, spontaneous cough was infrequently reported by subjects. Zofenopril/zofenoprilat PK analysis showed higher area under the curve of plasma concentration, τ values (ng/ml x h) than ramipril/ramiprilat (zofenopril vs. ramipril, 84.25 ± 34.47 vs. 47.40 ± 21.30; and zofenoprilat vs. ramiprilat, 653.67 ± 174.91 vs. 182.26 ± 61.28). Both ACE-i drugs did not affect BK plasma levels; in contrast, ramipril, but not zofenopril, significantly increased control FeNO values (from 24 ± 9.6 parts per billion [PPB] to 33 ± 16 PPB; p < 0.01). CONCLUSIONS Zofenopril has a more favourable profile when compared to ramipril as shown by a reduced pro-inflammatory activity and less impact on the cough reflex.

Abstract
Zofenopril, an inhibitor of the angiotensin-converting enzyme (ACE), has recently been widely introduced into the pharmaceutical market. Its clinical safety and efficacy has been demonstrated in patients with hypertension and in patients with acute myocardial infarction (AMI). The Survival of Myocardial Infarction Long-term Evaluation (SMILE) project provided valuable information regarding the safety of early onset ACE inhibition with zofenopril after AMI and a greater perception of the early and late benefits. The SMILE-I study demonstrated that most benefits of ACE inhibition may be obtained early after AMI and persist after discontinuation of treatment. The SMILE-II study demonstrated that early zofenopril treatment (initiated <12 h) is safe and associated with a low rate of severe hypotension in thrombolyzed patients with acute myocardial infarction when administered in accordance with an adequate dose-titration scheme. Many other studies of clinical ACE-inhibitors (ACEIs) over the last 30 years have provided us with information in order to understand the effects of ACEIs and have demonstrated that patients benefit from ACEI treatment at different stages of the pathophysiological continuum of cardiovascular diseases. The current guidelines recommend that ACEIs should be used for routine secondary prevention in all patients with coronary artery disease and should be considered for all other patients with coronary or other vascular disease unless contraindicated.

Abstract
Pediatric and adult cancer patients, following the use of the antitumor drug Doxorubicin develop cardiotoxicity. Pharmacological protection of microvascular endothelium might produce a double benefit: (i) reduction of myocardial toxicity (the primary target of Doxorubicin action) and (ii) maintenance of the vascular functionality for the adequate delivery of chemotherapeutics to tumor cells. This study was aimed to evaluate the mechanisms responsible of the protective effects of the angiotensin converting enzyme inhibitor (ACEI) Zofenoprilat against the toxic effects exerted by Doxorubicin on coronary microvascular endothelium. We found that exposure of endothelial cells to Doxorubicin (0.1-1μM range) impaired cell survival by promoting their apoptosis. ERK1/2 related p53 activation, but not reactive oxygen species, was responsible for Doxorubicin induced caspase-3 cleavage. P53 mediated-apoptosis and impairment of survival were reverted by treatment with Zofenoprilat. The previously described PI-3K/eNOS/endogenous fibroblast growth factor signaling was not involved in the protective effect, which, instead, could be ascribed to cystathionine gamma lyase dependent availability of H2S from Zofenoprilat. Furthermore, considering the tumor environment, the treatment of endothelial/tumor co-cultures with Zofenoprilat did not affect the antitumor efficacy of Doxorubicin. In conclusion the ACEI Zofenoprilat exerts a protective effect on Doxorubicin induced endothelial damage, without affecting its antitumor efficacy. Thus, sulfhydryl containing ACEI may be a useful therapy for Doxorubicin-induced cardiotoxicity.

Abstract
Many prodrug reviews describe specific examples of the successful application of prodrug technology to produce blockbuster drugs, such as simvastatin, omeprazole, acyclovir and enalapril. These reviews are helpful to understand the previous success stories and case histories of prodrug technology. The aim of the current review seeks to more clearly define quantitative trends in the changes in the physicochemical property parameters between the successful prodrug and the active parent molecule. This information can serve to guide medicinal chemists toward more successful pharmaceutical prodrugs in the future.

Abstract
Angiotensin-converting enzyme inhibitors are extensively used to improve clinical outcome of patients with several cardiovascular diseases. Zofenopril proved to be very effective in patients with coronary artery disease and myocardial infarction, thanks to its unique effective mechanism of action for improving blood pressure control, left ventricular function and myocardial ischemia burden, as well as angiotensin-converting enzyme inhibition. The SMILE project involved more than 3500 patients with coronary artery disease and demonstrated that zofenopril treatment may reduce mortality and morbidity in patients with myocardial infarction, also when combined with acetyl salicylic acid and to a greater extent than lisinopril and ramipril. In addition, the results of the SMILE-ISCHEMIA study have demonstrated an interesting anti-ischemic effect of zofenopril, and these properties largely contribute to the overall clinical benefit of the drug. The effects of zofenopril on blood pressure control and cardiovascular protection clearly support its primary role for prevention and treatment of cardiovascular diseases.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to investigate the effect of chronic treatment with antihypertensive and non-antihypertensive doses of zofenopril on cardiovascular changes in spontaneously hypertensive rats (SHR). EXPERIMENTAL APPROACH Male SHR were treated with 0.5 or 10 mg kg(-1) per day of zofenopril (Z(0.5) and Z(10)) for 3 months. SHR and Wistar-Kyoto rats (WKY) receiving vehicle were used as controls. Systolic blood pressure was measured using the tail cuff method. Left ventricular weight/body weight ratio was calculated as cardiac hypertrophy index. Angiotensin converting enzyme (ACE) activity was determined in plasma and tissues by a fluorimetric method. Vascular reactivity was evaluated on aortic rings by acetylcholine and sodium nitroprusside relaxations. Effects on vascular structure were assessed by lumen diameter, wall thickness and medial cross-sectional area determination. Superoxide anion generation was quantified using lucigenin-amplified chemiluminescence in aorta. RESULTS Long-term daily administration of zofenopril (10 mg kg(-1)) to SHR reduced blood pressure to WKY values, decreased cardiac hypertrophy, improved the acetylcholine-induced relaxant response and reversed the vascular remodelling. ACE inhibition and antioxidant activity were involved in these effects. 0.5 mg kg(-1) per day of zofenopril slightly modified blood pressure and the other effects were weaker. CONCLUSIONS AND IMPLICATIONS Antihypertensive effects of chronic treatment with zofenopril were accompanied by recovery of endothelial function and improvement of cardiovascular structure. Low-dose zofenopril had little effect on blood pressure, with some benefits on cardiovascular structure and function. Inhibition of ACE and antioxidant activity were involved in these effects.

Abstract
A series of new 3-mercapto-2-methyl-propanoyl-pyrrolidine derivatives (V, VIa-e) were designed. A new validated ACE inhibitors pharmacophore model (hypothesis) was generated for the first time in this research from the biologically active (frozen) conformation of Lisinopril-Human ACE complex that was downloaded from PDB, using stepwise technique of CATALYST modules. The molecular modeling compare-fit study of the designed molecules (V, VIa-e), with such ACE inhibitors hypothesis was fulfilled, and several compounds showed significant high simulation fit values. The compounds with high fit values were synthesized and biologically evaluated in vivo as hypotensive agents. It appears that the in vivo hypotensive activity of compounds V, VIa, VIb, and VIe was consistent with their molecular modeling results, and compound VIe showed the highest activity in comparison to Captopril.

Abstract
Alcohol-induced endothelial changes might contribute to an increase in blood pressure in regular alcohol consumers. Some antihypertensive drugs affect oxidative stress and endothelial function and might counteract the effects of alcohol at the cellular level. The aim of this study was to investigate in vitro the effects of three different types of antihypertensive agents on alcohol-induced endothelial responses and oxidative stress. Cultured human endothelial cells were exposed to increasing concentrations (1, 10, 60 micromol/L) of zofenoprilat, carvedilol, and lacidipine in the absence and in the presence of ethanol (140 mmol/L). Concentrations of endothelin (ET) and nitric oxide (NO) were measured in the culture media as markers of endothelial function, and malondialdehyde (MDA) and intracellular glutathione (GSHi) were measured as markers of oxidative stress. Exposure to alcohol increased the levels of ET, NO, and MDA, and decreased GSHi. Carvedilol and zofenoprilat were more effective than lacidipine in counteracting the effects of alcohol on ET production. Alcohol-induced NO production was enhanced by carvedilol, whereas zofenoprilat and lacidipine did not have a significant effect. The alcohol-induced increase in MDA concentrations was blunted by all three drugs, but only carvedilol restored a normal response. All three drugs increased GSHi levels, with the effect being greater for carvedilol and lacidipine than zofenoprilat. Carvedilol is more effective than zofenoprilat and lacidipine in counteracting alcohol-induced endothelial responses in vitro and in decreasing oxidative stress. These effects might be particularly beneficial in patients with alcohol-related hypertension.

Abstract
Zofenopril is a specific ACE inhibitor with antihypertensive, remarkable antioxidant, and cardioprotective properties, including the ability to improve endothelial function and protect against ischemia. These beneficial properties of zofenopril are believed to be due primarily to the presence of a sulfhydryl group and the highly lipophilic nature of the agent. As a potent, long-acting ACE inhibitor with tissue selectivity, it is a useful agent for the treatment of a number of cardiovascular diseases. ACE inhibitors block the renin-angiotensin-aldosterone system (RAAS) and are recommended in the management of hypertension with associated risk factors because of their renoprotective and cardioprotective effects. There is a robust body of comparative data supporting zofenopril as an effective and well tolerated ACE inhibitor for treating hypertension. Hypertensive patients frequently require combination therapy to adequately control BP. ACE inhibitors combined with a diuretic make a very effective combination, as a result of the synergistic mechanisms of these two drug classes that allow good efficacy and favorable tolerability at low doses. The combination of zofenopril and hydrochlorothiazide is effective and superior to monotherapy with either agent. Clinical studies have demonstrated that early administration of zofenopril in patients with acute myocardial infarction is effective and well tolerated for reducing the incidence of major cardiovascular events in at-risk patients, and it is believed that much of the benefit is a result of the primary cardioprotective effect of zofenopril.

Abstract
Sodium depletion with diuretics augments the efficacy of angiotensin-converting enzyme-inhibitor therapy for hypertension and renal dysfunction, and possibly for left ventricular dysfunction after myocardial infarction. Underlying mechanisms may involve altered angiotensin-converting enzyme-inhibitor pharmacokinetics. We hypothesized that the diuretic hydrochlorothiazide causes increased steady-state levels of the angiotensin-converting enzyme-inhibitors lisinopril and zofenopril in rats with myocardial infarction. Rats were subjected to coronary ligation to induce myocardial infarction. After 1 week, rats were randomized to 50 mg/kg/day hydrochlorothiazide or control treatment for 3 weeks. The last week, rats received lisinopril or zofenopril in equipotentent dosages (3.3 and 10 mg/kg/day, respectively). Rats were sacrificed at Tmax after the last dose of angiotensin-converting enzyme-inhibitor, and tissues were collected for analysis of drug concentrations. Lisinopril concentrations in plasma were significantly increased by hydrochlorothiazide, at unchanged tissue concentrations. This increase could be fully explained by decreased renal function, as evidenced by increased plasma creatinine levels (lisinopril + hydrochlorothiazide 82+/-5 microM versus lisinopril 61+/-5 microM, P < 0.001). In contrast, zofenoprilat levels in kidney and non-infarcted left ventricle were markedly increased by hydrochlorothiazide, whereas plasma concentrations were unchanged. Although hydrochlorothiazide tended to increase plasma creatinine in zofenopril-treated rats as well, this increase was less pronounced (zofenopril + hydrochlorothiazide 61+/-3 microM versus zofenopril 54+/-2 microM, P = 0.15). Hydrochlorothiazide increases steady-state angiotensin-converting enzyme-inhibitor drug levels, most likely by affecting their renal clearance. Notably, the lipophilic angiotensin-converting enzyme-inhibitor zofenopril accumulated in tissue, whereas the hydrophilic lisinopril increased in plasma. Whether combining different angiotensin-converting enzyme-inhibitors with hydrochlorothiazide translates into distinct clinical profiles requires further study.

Abstract
Based on preclinical and clinical findings, zofenopril appears to be an angiotensin-converting enzyme (ACE) inhibitor with high potency, significant tissue selectivity and a long duration of action. Its ancillary properties, such as antioxidant activity and cardiovascular (CV) protection, make this drug potentially suitable for the treatment, and possibly prevention, of several CV diseases. There is a large body of evidence that support a complex interaction between ACE inhibitors and CV disease. A review of the preclinical profile of zofenopril clearly suggest that such interaction can be even more complex and could involve some drug-specific properties directly involved in the definition of the overall clinical profile of zofenopril as emerged from randomised clinical trials. In particular, zofenopril combines the feature of an effective ACE inhibitor, with plasma and tissue activity, along with that of an antioxidant compound, and both these characteristics can contribute to its capacity of controlling hypertension and improving the prognosis of patients with coronary artery disease. The results of The Survival of Myocardial Infarction Long term Evaluation (SMILE) trials have demonstrated that the early administration of zofenopril to patients with acute myocardial infarction is associated with a significant reduction in the 6-week occurrence of major CV events (death and congestive heart failure) in high-risk patients with anterior non-thrombolysed myocardial infarction, and this effect is enhanced in some higher-risk subgroups of patients, such as those with a history of diabetes or arterial hypertension.

Abstract
This study has compared the effects of two structurally different angiotensin converting enzyme inhibitors (ACEis) such as zofenopril (Zof, with sulfhydrylic group) and lisinopril (Lis, with carboxylic group) and an angiotensin II AT(1) receptor antagonist (losartan, Los) on the prevention of cardiac hypertrophy and collagen distribution in spontaneously hypertensive rats (SHRs). The SHRs were untreated or received: Zof (10 mg/kg/day), Lis (10 mg/kg/day) or Los (20 mg/kg/day) in drinking water starting at 4 weeks of age. At 8, 16 and 24 weeks of age, 8 rats/group were sacrificed for determination of blood pressure, cardiac hypertrophy and collagen distribution. All treatments significantly decreased blood pressure and cardiac indices, expressed as the ventricles to body weight ratio, both variables being significantly correlated. Total ventricular collagen content was similarly decreased in all treated groups. Zof significantly increased the expression of collagen type III and normalized the collagen type I/III ratio. These results suggest that the effects of these drugs on different types of collagen are independent from angiotensin II formation. Similar findings obtained with captopril seem to indicate that the antioxidant sulfhydrylic group of these ACEis can play a role in the distribution of collagen during cardiac hypertrophy.

Abstract
We investigated the effect of different ACE inhibitors on tissue injury in isolated rat hearts subjected to 30 minutes of ischemia followed by 120 minutes of reperfusion. Zofenoprilat (1-100 microM), but not enalaprilat or lisinopril, significantly reduced infarct size, as estimated on the basis of triphenyltetrazolium chloride staining. The protection was not reproduced by the angiotensin II receptor antagonist irbesartan, and it was partly abolished by the bradykinin receptor antagonist HOE 140. Zofenoprilat molecule contains a sulfhydryl group, and its administration, as compared with enalaprilat or lisinopril administration, was associated with better preservation of protein thiols at the end of ischemia. We conclude that zofenopril has a specific cardioprotective effect, which might be related either to interference with bradykinin metabolism or to preservation of protein sulfhydryl groups.

[11C]2 labelling procedures were based on the use of immobilized Grignard reagent and the acylation of (S)-4-phenylthio-L-proline methyl ester (5) with 11C-labelled methacryloyl chloride, followed by a Michael addition with thiobenzoic acid. The radiochemical yield was 5-10% (EOB, decay corrected) and specific radioactivity ranged from 0.5 to 1.5 Ci/micromol (18.5-55.5 GBq/micromol). Preliminary in vivo human evaluation of [11C]2 showed that the drug accumulates in organs which express high levels of ACE, like lungs and kidneys, and in organs involved in drug metabolism such as the liver and gall bladder. Results of the distribution of [11C]2 showed a measurable concentration of the drug in the target tissues such as the kidney and to a minor extent, the heart, where it can afford organ protection.

Abstract
Zofenopril (1) is a new ACE inhibitor, used in therapy for hypertension and post-myocardial infarction. The protonated quasi-molecular ion (m/z 430) of 1, obtained under positive electrospray ionization conditions, loses a benzoic acid molecule (m/z 308), which in turn decomposes via loss of CO (m/z 280) when low-energy collisional-induced dissociation (CID) and in-source experiments are performed. This rearrangement is the main fragmentation process and can be observed both in-source and in the product ion tandem mass spectra, using either an ion trap or a triple quadrupole instrument. Other known diastereoisomers of 1, an impurity with an acetyl in the place of the benzoyl group (2) and an impurity with two propanoyl chains in series (3), give the same rearrangement. On the other hand, the mass spectra of the methyl ester (4) and an impurity with two proline moieties (5) do not show this unusual fragmentation. Time-resolved CID spectra of 1 show that the rearrangement occurs after about 2 ms, a time scale comparable to those of the other non-rearrangement cleavages. These experiments suggest a conformation in the gas phase for 1 in which the benzoyl group is close to the hydroxyl of the carboxylic acid group, from which the rearrangement could readily occur. Since compounds 4 and 5 do not show the same behaviour, the presence of a carboxylic acid in the proline ring seems to play a crucial role in the rearrangement, probably due to an intramolecular hydrogen bond. To confirm this hypothesis, deuterium exchanges in mass spectrometric experiments and a conformational analysis via computational methods were performed.

Abstract
The effects of chronic treatment with the new sulfhydryl angiotensin-converting enzyme (ACE)-inhibitor, zofenopril, in comparison with the classical sulfhydryl ACE-inhibitor captopril or enalapril or placebo on the development of atherosclerosis were determined in apolipoprotein-E knockout (apoE(-/-)) mice. Groups of 2-month-old male mice received either placebo (N=10), 0.05 mg/kg/day of zofenopril (N=10), 1 mg/kg/day of zofenopril (N=10), 5 mg/kg/day of captopril (N=10) or 0.5 mg/kg/day of enalapril (N=8). After 29 weeks of treatment, computer-assisted imaging analysis revealed that zofenopril reduced the aortic cumulative lesion area by 78% at 0.05 mg/kg/day and by 89% at 1 mg/ml/day of zofenopril compared to that of the placebo (P<0.0001). Captopril reduced by 52% aortic lesions compared to placebo (P<0.01 vs. placebo; P<0.05 vs. zofenopril at both doses). Enalapril did not reduce aortic lesions. Furthermore, 0.05 mg/kg/day of zofenopril reduced susceptibility of plasma LDL to in vitro oxidation compared to captopril, enalapril or placebo, as shown by significant reduction of malondialdehyde content (P<0.001 vs. placebo or enalapril; P<0.05 vs. captopril), as well as by the prolongation of lag-time (P<0.01 vs. placebo or enalapril P<0.05 vs. captopril). More importantly, mice treated with 1 mg/ml/day of zofenopril had a significant decrease in the intimal immunohistochemical presence of oxidation-specific epitopes on oxLDL (NA59 monoclonal antibody, P<0.01), macrophages derived foam cells (F4/80 monoclonal antibody, P<0.05) and native LDL (NP monoclonal antibody, P<0.01) compared to placebo, captopril or enalapril. Thus, chronic treatment with the new sulfhydryl ACE-inhibitor zofenopril has antiatherosclerotic and antioxidant effects in the arterial wall of hypercholesterolemic apoE(-/-) mice. This protection was significantly higher than that reached with captopril and at lower doses of the drug. Treatment with 0.5 mg/kg/day of enalapril did not provide any protective effect.

Abstract
We have studied the effect of zofenopril, a new angiotensin-converting enzyme inhibitor in preventing cardiac injury induced by chronic doxorubicin treatment in rats. Cardiac function was assessed by measuring changes in electrocardiogram (ECG) tracings, haemodynamics and cardiac responses in vivo to isoprenaline, 4 weeks after suspension of doxorubicin treatment, in vehicle-treated rats and in animals receiving zofenopril (15 mg/kg/os/day) alone, doxorubicin (1.5 mg/kg i.v. once a week for 5 weeks) or zofenopril+doxorubicin treatment. Doxorubicin induced a significant lengthening of the QalphaT interval, which was completely prevented by zofenopril treatment. The cardiac positive inotropic effect induced by i.v. isoprenaline was selectively depressed by doxorubicin (no changes in chronotropic responses) and this adverse effect of doxorubicin was also prevented in zofenopril+doxorubicin pretreated rats. Doxorubicin induced a significant increase in relative heart weight, which was likewise prevented in zofenopril+doxorubicin treated rats. In separate experiments, zofenopril did not interfere with the antitumor activity of doxorubicin (inhibition of tumor growth in nude mice xenografted with A2780 human tumor line). In conclusion, the oral administration of zofenopril is able to significantly ameliorate, up to 4 weeks after the end of doxorubicin administration, doxorubicin-induced cardiotoxicity without affecting the antitumor activity of this anthracycline.
