Abstract
Inhibition of CYP11B1 is a promising therapy for severe diseases caused by excessive cortisol. Enantiomer discrimination provides clues to achieve selectivity that CYP11B1 and homologous CYP11B2 were selectively bound by S- and R-fadrozole, respectively, in distinct binding modes. Pyridyl 4,5,6,7-tetrahydro-4,7-methanobenzo[d]isoxazoles showing a similar binding mode to S-fadrozole in CYP11B1 were designed as potent and selective CYP11B1 inhibitors. Compound 7aa exhibited a highly potent CYP11B1 inhibition similar to that of the drug osilodrostat (IC50's of 9 and 6 nM, respectively) but was 1500-fold more selective over CYP11B2 compared to osilodrostat (selectivity factors of 125 versus 0.08, respectively). Strong reductions of plasma cortisol concentrations by compound 7aa were demonstrated in rats without interference in aldosterone production after oral application. It showed no inhibition against a panel of steroidogenic and hepatic CYP enzymes. Exhibiting a good pharmacokinetic profile, compound 7aa was considered as a drug candidate for further development.

Abstract
Recent reports described cases of severe hypertension and hypokalemia accompanied by low renin and aldosterone levels during antifungal therapy with posaconazole and itraconazole. These conditions represent characteristics of secondary endocrine hypertension caused by mineralocorticoid excess. Different mechanisms can cause mineralocorticoid excess, including inhibition of the adrenal steroidogenic enzymes CYP17A1 and CYP11B1, inhibition of the peripheral cortisol oxidizing enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) or direct activation of the mineralocorticoid receptor (MR). Compared to previous experiments revealing a threefold more potent inhibition of 11β-HSD2 by itraconazole than with posaconazole, the current study found sevenfold stronger CYP11B1 inhibition by posaconazole over itraconazole. Both compounds most potently inhibited CYP11B2. The major pharmacologically active itraconazole metabolite hydroxyitraconazole (OHI) resembled the effects of itraconazole but was considerably less active. Molecular modeling calculations assessed the binding of posaconazole, itraconazole and OHI to 11β-HSD2 and the relevant CYP enzymes, and predicted important interactions not formed by the other systemically used azole antifungals, thus providing an initial explanation for the observed inhibitory activities. Together with available clinical observations, the presented data suggest that itraconazole primarily causes pseudohyperaldosteronism through cortisol-induced MR activation due to 11β-HSD2 inhibition, and posaconazole by CYP11B1 inhibition and accumulation of the mineralocorticoids 11-deoxycorticosterone and 11-deoxycortisol because of hypothalamus-pituitary-adrenal axis (HPA) feedback activation. Therapeutic drug monitoring and introduction of upper plasma target levels may help preventing the occurrence of drug-induced hypertension and hypokalemia. Furthermore, the systemically used azole antifungals voriconazole, isavuconazole and fluconazole did not affect any of the mineralocorticoid excess targets, offering alternative therapeutic options.

Abstract
Humans are constantly exposed to a multitude of environmental chemicals that may disturb endocrine functions. It is crucial to identify such chemicals and uncover their mode-of-action to avoid adverse health effects. 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) catalyze the formation of cortisol and aldosterone, respectively, in the adrenal cortex. Disruption of their synthesis by exogenous chemicals can contribute to cardio-metabolic diseases, chronic kidney disease, osteoporosis, and immune-related disorders. This study applied in silico screening and in vitro evaluation for the discovery of xenobiotics inhibiting CYP11B1 and CYP11B2. Several databases comprising environmentally relevant pollutants, chemicals in body care products, food additives and drugs were virtually screened using CYP11B1 and CYP11B2 pharmacophore models. A first round of biological testing used hamster cells overexpressing human CYP11B1 or CYP11B2 to analyze 25 selected virtual hits. Three compounds inhibited CYP11B1 and CYP11B2 with IC50 values below 3 μM. The most potent inhibitor was epoxiconazole (IC50 value of 623 nM for CYP11B1 and 113 nM for CYP11B2, respectively); flurprimidol and ancymidol were moderate inhibitors. In a second round, these three compounds were tested in human adrenal H295R cells endogenously expressing CYP11B1 and CYP11B2, confirming the potent inhibition by epoxiconazole and the more moderate effects by flurprimidol and ancymidol. Thus, the in silico screening, prioritization of chemicals for initial biological tests and use of H295R cells to provide initial mechanistic information is a promising strategy to identify potential endocrine disruptors inhibiting corticosteroid synthesis. A critical assessment of human exposure levels and in vivo evaluation of potential corticosteroid disrupting effects by epoxiconazole is required.

Abstract
Cytochrome P450 (P450, CYP) enzymes have long been of interest due to their roles in the metabolism of drugs, pesticides, pro-carcinogens, and other xenobiotic chemicals. They have also been of interest due to their very critical roles in the biosynthesis and metabolism of steroids, vitamins, and certain eicosanoids. This review covers the 22 (of the total of 57) human P450s in Families 5-51 and their substrate selectivity. Furthermore, included is information and references regarding inducibility, inhibition, and (in some cases) stimulation by chemicals. We update and discuss important aspects of each of these 22 P450s and questions that remain open.

Abstract
INTRODUCTION Cushing's syndrome (CS) is a metabolic disorder caused by chronic hypercortisolism. CS is associated with cardiovascular, metabolic, skeletal and psychological dysfunctions and can be fatal if left untreated. The first-line treatment for all forms of CS is a surgery. However, medical therapy has to be chosen if surgical resection is not an option or is deemed ineffective. Currently available therapeutics are either not selective and have side effects or are only available as an injection (pasireotide). Areas covered: The authors discuss the recent drug developments for the medical treatment of CS through two validated molecular targets. Specifically, the authors look at selective inhibitors of CYP11B1 that reduce cortisol production by inhibiting steroid 11beta-hydroxylase and glucocorticoid receptor (GR) antagonists that interrupt cortisol-mediating transcriptional regulation of related genes. Expert opinion: Patients with CS have limited treatment options; indeed, there is an unmet need for new compounds that target CYP11B1 selectively versus several steroidogenic enzymes and/or GR-signaling pathways. The complexity of steroid biosynthesis and signaling requires the application of structure-based drug discovery techniques that use molecular targets and highly similar off-targets. Significant differences in steroidogenesis between humans and other species necessitates caution over the choice of in vivo model for the preclinical evaluation of future potential compounds.

Abstract
The mineralocorticoid aldosterone is an important regulator of blood pressure and electrolyte balance. However, excess aldosterone can be deleterious as a driver of inflammation, vascular remodeling and tissue fibrosis associated with cardiometabolic diseases. Mineralocorticoid receptor antagonists (MRA) and renin-angiotensin-aldosterone system (RAAS) antagonists are current clinical therapies used to antagonize deleterious effects of aldosterone in patients. MRAs compete with aldosterone for binding at its cognate receptor thereby limiting its effect while RAS antagonists reduce aldosterone levels indirectly by blocking the stimulatory effect of angiotensin. Both MRAs and RAS antagonists can result in incomplete inhibition of the harmful effects of excess aldosterone. Aldosterone synthase (AS) inhibitors (ASI) attenuate the production of aldosterone directly and have been proposed as an alternative to MRAs and RAS blockers. Cortisol synthase (CS) is an enzyme closely related to AS and responsible for generating the important glucocorticoid cortisol, required for maintaining critical metabolic and immune responses. The importance of selectivity against CS is shown by early examples of ASIs that were only modestly selective and as such, attenuated cortisol responses when evaluated in patients. Recently, next-generation, highly selective ASIs have been described and are presently being evaluated in the clinic as an alternative to angiotensin and MR antagonists for cardiometabolic disease. Herein we provide a brief review of the challenges associated with discovery of selective ASIs and the transition from the early compounds that paved the way toward the next-generation of highly selective ASIs currently under development.

Abstract
Cortisol synthase (CYP11B1) is the main enzyme for the endogenous synthesis of cortisol and its inhibition is a potential way for the treatment of diseases associated with increased cortisol levels, such as Cushing's syndrome, metabolic diseases, and delayed wound healing. Aldosterone synthase (CYP11B2) is the key enzyme for aldosterone biosynthesis and its inhibition is a promising approach for the treatment of congestive heart failure, cardiac fibrosis, and certain forms of hypertension. Both CYP11B1 and CYP11B2 are structurally very similar and expressed in the adrenal cortex. To facilitate the identification of novel inhibitors of these enzymes, ligand-based pharmacophore models of CYP11B1 and CYP11B2 inhibition were developed. A virtual screening of the SPECS database was performed with our pharmacophore queries. Biological evaluation of the selected hits lead to the discovery of three potent novel inhibitors of both CYP11B1 and CYP11B2 in the submicromolar range (compounds 8–10), one selective CYP11B1 inhibitor (Compound 11, IC50 = 2.5 μM), and one selective CYP11B2 inhibitor (compound 12, IC50 = 1.1 μM), respectively. The overall success rate of this prospective virtual screening experiment is 20.8% indicating good predictive power of the pharmacophore models.

Abstract
Elevated levels of aldosterone are associated with arterial hypertension, congestive heart failure, chronic kidney disease, and obesity. Aldosterone is produced predominantly in the zona glomerulosa of the cortex of the adrenal gland by the enzyme aldosterone synthase (CYP11B2). Treatment of the above indications by decreasing production of aldosterone is thought to be of therapeutic benefit by lessening the deleterious effects of aldosterone mediated through both the mineralocorticoid receptor and also through so called non-genomic pathways. However, inhibition of the highly similar enzyme, CYP11B1, which is responsible for the production of cortisol, must be avoided in the development of clinically useful aldosterone synthase inhibitors due to the resulting impairment of the cortisol-induced stress response. In efforts to assess the interactions of compounds with the CYP11B enzymes, a variety of cell-based inhibitor screening assays for both CYP11B1 and CYP11B2 have been reported. Herein we report details of assays employing both cynomolgus monkey adrenal homogenate (CAH) and human adrenal homogenate (HAH) as sources of CYP11B1 and CYP11B2 enzymes. Utilizing both CAH and HAH, we have characterized the kinetics of the CYP11B1-mediated conversion of 11-deoxycortisol to cortisol and the CYP11B2-mediated oxidation of corticosterone to aldosterone. Inhibition assays for both CYP11B1 and CYP11B2 were subsequently developed. Based on a comparison of human and monkey amino acid sequences, kinetics data, and inhibition values derived from the HAH and CAH assays, evidence is provided in support of using cynomolgus monkey tissue-derived cell homogenates as suitable surrogates for the human enzymes.

Abstract
The inhibition of 11β-hydroxylase is a promising strategy for the treatment of Cushing's syndrome, in particular for the recurrent and subclinical cases. To achieve proof of concept in rats, efforts were paid to identify novel lead compounds inhibiting both human and rat CYP11B1. Modifications on a potent promiscuous inhibitor of hCYP11B1, hCYP11B2 and hCYP19 (compound IV) that exhibited moderate rCYP11B1 inhibition led to compound 8 as a new promising lead compound. Significant improvements compared to starting point IV were achieved regarding inhibitory potency against both human and rat CYP11B1 (IC50 values of 2 and 163 nM, respectively) as well as selectivity over hCYP19 (IC50 = 1900 nM). Accordingly, compound 8 was around 7- and 28-fold more potent than metyrapone regarding the inhibition of human and rat CYP11B1 and exhibited a comparable selectivity over hCYP11B2 (SF of 3.5 vs 4.9). With further optimizations on this new lead compound 8, drug candidates with satisfying profiles are expected to be discovered.

Abstract
CYP11B2 inhibition is a promising treatment for diseases caused by excessive aldosterone. To improve the metabolic stability in human liver miscrosomes of previously reported CYP11B2 inhibitors, modifications were performed via a combination of ligand- and structure-based drug design approaches, leading to pyridyl 4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolones. Compound 26 not only exhibited a much longer half-life (t1/2 ≫ 120 min), but also sustained inhibitory potency (IC50 = 4.2 nM) and selectivity over CYP11B1 (SF = 422), CYP17, CYP19, and a panel of hepatic CYP enzymes.

Abstract
Dual CYP17/CYP11B2 inhibitors are proposed as a novel strategy for the treatment of prostate cancer to reduce risks of cardiovascular diseases. Via a combination of ligand- and structure-based approaches, a series of dual inhibitors were designed leading to the 2-(3-pyridyl)naphthalenes 10 and 11 with strong inhibition of both enzymes (IC50 values around 20 nM) and excellent selectivities over CYP11B1, CYP19, and CYP3A4. These compounds are considered as promising candidates for further in vivo evaluation.

Abstract
Imidazolylmethylflavones previously reported by us as aromatase inhibitors proved to be able to interact with aldosterone synthase (CYP11B2), a cytochrome P450 enzyme involved in the biosynthesis of the mineralcorticoid hormone aldosterone, and were used to obtain a pharmacophore model for this enzyme. Here, in the search for potential ligands for CYP11B2 and the related CYP11B1, a virtual screening of a small compounds library of our earlier synthesized aromatase inhibitors was performed and, according to the results and the corresponding biological data, led to the design and synthesis of a series of xanthones derivatives carrying an imidazolylmethyl substituent in position 1 and different substituents in position 4. Some very potent inhibitors were obtained; in particular, the 4-chlorine derivative was active in the low nanomolar or subnanomolar range on CYP11B2 and CYP11B1, respectively, proving that xanthone can be considered as an excellent scaffold, whose activity can be directed to different targets when appropriately functionalized.

Abstract
Aldosterone synthase (CYP11B2) is a promising therapeutic target for the treatment of cardiovascular diseases related to abnormally high aldosterone levels. On the basis of our previously identified lead compounds I–III, a series of 3-pyridinyl substituted aliphatic cycles were designed, synthesized and tested as CYP11B2 inhibitors. Aromaticity abolishment of the core was successfully applied to overcome the undesired CYP1A2 inhibition. This study resulted in a series of potent and selective CYP11B2 inhibitors, with compound 12 (IC50 = 21 nM, SF = 50) as the most promising one, which shows no inhibition toward CYP1A2 at 2 µM. The design conception demonstrated in this study can be helpful in the optimization of CYP inhibitor drugs regarding CYP1A2 selectivity.

Abstract
Aldosterone, the most important human mineralocorticoid, is involved in the regulation of the blood pressure and has been reported to play a key role in the formation of arterial hypertension, heart failure and myocardial fibrosis. Aldosterone synthase (CYP11B2) catalyzes the biosynthesis of aldosterone by successive 11β- and 18-hydroxylation followed by an 18-oxidation of 11-deoxycorticosterone and thus comprises an important drug target. For more than 20 years, all attempts to purify recombinant human CYP11B2 in significant amounts for detailed analysis failed due to its hydrophobic nature as a membrane protein. Here, we present the successful expression of the protein in E. coli yielding approx. 90 nmol/l culture, its purification and detailed enzymatic characterization. Biochemical analyses have been performed using in vitro conversion assays which revelead a V(max) of 238±8 nmol products/nmol hCYP11B2/min and a K(m) of 103±8 μM 11-deoxycorticosterone. Furthermore, binding analyses indicated a very loose binding of the first intermediate of the reaction, corticosterone with a K(d) value of 115±6 μM whereas for 11-deoxycorticosterone a K(d) of 1.34±0.13 μM was estimated. Upon substrate conversion of 11-deoxycorticosterone, new intermediates have been identified as 19- and 18-hydroxylated products not described before for the human enzyme. To understand the differences in substrate conversion, we constructed a new homology model based on the 3D structure of CYP11A1, performed docking studies and calculated the activation energy for hydrogen abstraction of the different ligands. The data demonstrated that the 11β-hydroxylation requires much less abstraction energy than hydroxylation at C18 and C19. However, the C18 and C19 hydroxylated products might be of clinical importance. Finally, purified CYP11B2 represents a suitable tool for the investigation of potential inhibitors of this protein for the development of novel drugs against hypertension and heart failure as was shown using ketoconazole.

Abstract
CYP11B1 is the key enzyme in cortisol biosynthesis, and its inhibition with selective compounds is a promising strategy for the treatment of diseases associated with elevated cortisol levels, such as Cushing's syndrome or metabolic disease. Expanding on a previous study from our group resulting in the first potent and rather selective inhibitor described so far (1, IC50 = 152 nM), we herein describe further optimizations of the imidazolylmethyl pyridine core. Five compounds among the 42 substances synthesized showed IC50 values below 50 nM. Most interesting was the naphth-1-yl compound 23 (IC50 = 42 nM), showing a 49-fold selectivity toward the highly homologous CYP11B2 (1: 18-fold) as well as selectivity toward the androgen and estrogen forming enzymes CYP17 and CYP19, respectively.

Abstract
Cytochrome P450 enzymes play an important role in steroid hormone biosynthesis of the human adrenal gland, e.g., the production of cortisol and aldosterone. Aldosterone, the most important human mineralocorticoid, is involved in the regulation of the salt and water homeostasis of the body and thus in the regulation of blood pressure, whereas cortisol is the most important glucocorticoid of the human body. CYP11B-dependent steroid hydroxylases are drug development targets, and since they are very closely related enzymes, the discovery of selective inhibitors has been subject to intense investigations for several years. Here we report the development of a whole-cell medium throughput screening technology for the discovery of CYP11B2 inhibitors. The new screening system displayed high reproducibility and was applied to investigate a library of pharmacologically active compounds. 1268 compounds were investigated during this study which revealed 5 selective inhibitors of CYP11B2 (after validation against CYP11B1). The new inhibitors of CYP11B2 are already existing drugs that could be used either in the treatment of hyperaldosteronism-related diseases or as lead compounds that could further be optimised to achieve safer and selective inhibitors of aldosterone synthase.

Abstract
Outgoing from an etomidate-based design concept, we succeeded in the development of a series of highly active and selective inhibitors of CYP11B1, the key enzyme of cortisol biosynthesis, as potential drugs for the treatment of Cushing's syndrome and related diseases. Thus, compound 33 (IC50 = 152 nM) is the first CYP11B1 inhibitor showing a rather good selectivity toward the most important steroidogenic CYP enzymes aldosterone synthase (CYP11B2), the androgen-forming CYP17, and aromatase (estrogen synthase, CYP19).

Abstract
Adrenodoxin is probably the best characterized member of the vertebrate-type [2Fe-2S]-cluster ferredoxins. It has been in the spotlight of scientific interest for many years due to its essential role in mammalian steroid hormone biosynthesis, where it acts as electron mediator between the NADPH-dependent adrenodoxin reductase and several mitochondrial cytochromes P450. In this review we will focus on the present knowledge about protein-protein recognition in the mitochondrial cytochrome P450 system and the modulation of the electron transfer between Adx and its redox partners, AdR and CYP(s). We also intend to point out the potential biotechnological applications of Adx as a versatile electron donor to different cytochromes P450, both in vitro and in vivo. Finally we will address the comparison between the mammalian cytochrome P450-associated adrenodoxin and ferredoxins involved in iron-sulfur-cluster biosynthesis. Despite their different functions, these proteins display an amazing similarity regarding their primary sequence, tertiary structure and biophysical features.

Abstract
Aldosterone plays a crucial role in salt and water homeostasis but in case of pathologically increased plasma aldosterone levels it is also involved in the development and the progression of severe cardiovascular diseases like heart failure and myocardial fibrosis. For the treatment of these diseases we propose inhibition of the aldosterone forming enzyme CYP11B2 as a new pharmacological strategy. We recently developed in vitro highly potent and selective inhibitors of human CYP11B2, but the evidence of their in vivo activity is still missing. For this purpose, rat aldosterone synthase gene was cloned and expressed in V79MZ cells to establish a new screening assay for the identification of "rat-active" substances. Compound 7 from the class of heteroaryl substituted 3,4-dihydro-1H-quinolin-2-ones showed a moderate inhibitory effect (65% at 2 microM) on rat CYP11B2 in vitro. Furthermore, it diminished the conversion of deoxycorticosterone to aldosterone in rat adrenals and significantly reduced plasma aldosterone levels in vivo.

Abstract
Excessive production of aldosterone has been implicated in the pathogenesis of hypertension and heart failure. One approach to ameliorate the deleterious effects of aldosterone is to suppress its biosynthesis. The enzyme aldosterone synthase (CYP11B2) is responsible for the final step of aldosterone synthesis. It requires electron transfer from the adrenodoxin/adrenodoxin reductase system to catalyze the production of aldosterone. A stable cell line simultaneously overexpressing recombinant human CYP11B2 as well as human adrenodoxin and adrenodoxin reductase was established to help maximize the enzyme activity. The homogenate of these cells was used to develop an in vitro CYP11B2 assay using 11-deoxycorticosterone as a substrate. By the same strategy, another stable cell line simultaneously overexpressing human 11beta-hydroxylase (CYP11B1), an enzyme responsible for the final step of cortisol biosynthesis, and the two electron transfer proteins was also established, and an in vitro CYP11B1 assay using 11-deoxycortisol as a substrate was likewise developed to assess the selectivity of CYP11B2 inhibitors. FAD286, a reference CYP11B2 inhibitor, inhibited CYP11B2 and CYP11B1 activities with IC(50) values of 1.6+/-0.1 and 9.9+/-0.9 nM (mean+/-SEM, n=3-6), respectively. Kinetics studies revealed that the compound inhibited the activity of both enzymes competitively with respective K(i) values of 0.8+/-0.04 and 2.2+/-0.2 nM (n=3-4). These assays can be used for assessing the potency and selectivity of CYP11B2 inhibitors for the treatment of hypertension and heart failure.

Abstract
Mammalian cytochromes P450 have been shown to play highly important roles in the metabolism of drugs and xenobiotics as well as in the biosynthesis of a variety of endogenous compounds, many of them displaying hormonal function. The role of P450s as therapeutic targets is still inadequately recognized although several P450 inhibitors became efficient drugs that even reached blockbuster status. Here, we try to give a comprehensive overview on cytochromes P450s, which are already well-established targets - particularly focussing on the treatment of infectious diseases, metabolic disorders and cancer - and on those, which have a high potential to become successful targets. In addition, the design of inhibitors of cytochromes P450 will be discussed.

Abstract
Abiraterone, a steroidal cytochrome P450 17alpha-hydroxylase-17,20-lyase inhibitor (CYP17), is currently undergoing phase II clinical trials as a potential drug for the treatment of androgen-dependent prostate cancer. Since steroidal compounds often show side effects attributable to their structure, we have tried to replace the sterane scaffold by nonsteroidal core structures. The design and synthesis of 20 new abiraterone mimetics are described. Their activities have been tested with recombinant human CYP17 expressed in E. coli. Promising compounds were further evaluated for selectivity against CYP11B1, CYP11B2, and the hepatic CYP3A4. Compounds 19 and 20 showed comparable activity to abiraterone (IC50 values of 144 and 64 nM vs 72 nM) and similar or even better selectivity against the other CYP enzymes. Selected compounds were also docked into our homology model, and the same binding modes as for abiraterone were found.

Abstract
We previously showed that production of reactive oxygen species (ROS) caused by overexpression of the mitochondrial electron transfer protein adrenodoxin (Adx) induces apoptosis in mammalian cells. In the fission yeast Schizosaccharomyces pombe, ROS are also produced in cells that undergo an apoptotic-like cell death, but it is not yet clear whether they are actually causative for this phenomenon or whether they are merely produced as a by-product. Therefore, the purpose of this study was to trigger mitochondrial ROS production in fission yeast by overexpression of either wildtype Adx (Adx-WT) or of several activated Adx mutants and to investigate its consequences. It was found that strong expression of either Adx-WT or Adx-S112W did not produce any ROS, while Adx-D113Y caused a twofold and Adx1-108 a threefold increase in ROS formation as compared to basal levels. However, no typical apoptotic markers or decreased viability could be observed in these strains. Since we previously observed that an increase in mitochondrial ROS formation of about 60% above basal levels is sufficient to strongly induce apoptosis in mammalian cells, we conclude that S. pombe is either very robust to mitochondrial ROS production or does not undergo apoptotic cell death in response to mitochondrial ROS at all.

Abstract
In this study, the synthesis and biological evaluation of heteroaryl-substituted dihydronaphthalenes and indenes (1-16) is described. The compounds were tested for activity by use of human CYP11B2 expressed in fission yeast and V79 MZh cells and for selectivity by use of human CYP11B1, CYP17, and CYP19. The most active inhibitor was the 6-methoxydihydronaphthalene 4 (IC(50) = 2 nM), showing a K(i) value of 1.3 nM and a competitive type of inhibition. The 5-methoxyindene 3 was found to be the most selective CYP11B2 inhibitor (IC(50) = 4 nM; CYP11B1 IC(50) = 5684 nM), which also showed only marginal inhibition of human CYP3A4 and CYP2D6. Docking and molecular dynamics studies using our homology-modeled CYP11B2 structure were performed to understand some structure-activity relationships. Caco-2 cell experiments revealed highly cell-permeable compounds, and metabolic studies with 4 using rat liver microsomes showed sufficient stability.

Abstract
Steroid hormone biosynthesis is catalyzed by the action of a series of cytochrome P450 enzymes as well as reductases. Defects in steroid hydroxylating P450s are the cause of several severe defects such as the adrenogenital syndrome (AGS), corticosterone methyl oxidase (CMO) I or II deficiencies, or pseudohermaphroditism. In contrast, overproduction of steroid hormones can be involved in breast or prostate cancer, in hypertension, and heart fibrosis. Besides inhibiting the action of the steroid hormones on the level of steroid hormone receptors by using antihormones, which often is connected with severe side effects, more recently the steroid hydroxylases themselves turned out to be promising new targets for drug development. Since the 3-dimensional structures of steroid hydroxylases are not yet available, computer models of the corresponding CYPs may help to develop new inhibitors of these enzymes. During the past years, the necessary test systems have been developed and new compounds have been synthesized, which displayed selective and specific inhibition of CYP17, CYP11B2, and CYP11B1. With some of these potential new drugs, clinical trials are under way. It can be expected that in the near future some of these compounds will contribute to our arsenal of new and selective drugs.

Abstract
To identify enantioselective nonsteroidal aromatase inhibitors, a multidisciplinary medicinal chemistry approach was pursued. First, our earlier CoMFA model [Bioorg. Med. Chem. 1998,6, 377-388] was extended taking purposely into account previously discovered enantioselective aromatase inhibitors. The 3D QSAR model was then exploited to design chiral ligands, whose configurational assignment was obtained, after HPLC separation, by means of a combination of circular dichroism measurements and time dependent density functional calculations. Finally, the new enantiomeric inhibitors were separately tested to ascertain both their potency against the cytochrome P450 aromatase (CYP19; EC 1.14.14.1), and their selectivity relative to another enzyme of the P450 family. A satisfactory agreement between experimental and predicted data allowed us to assert that a properly built "enantioselective CoMFA model" might constitute a useful tool for addressing enantioselective ligands design.
