Description

RECEPTOR ANTAGONISTS IL-8 FIELD OF THE INVENTION This invention relates to novel substituted benzoisothiazole compounds, pharmaceutical compositions, methods for their preparation, and use thereof for treating diseases mediated by IL-8, GROa, GROß, GRO ?, ENA-78 and NAP-2.
BACKGROUND OF THE INVENTION Many different names have been applied to interleukin (IL-8), as neutrophil activating / activating protein -1 (NAP-1), monocyte-derived neutrophil chemotactic factor (MDNCF), neutrophil activating factor (NAF), and T-cell lymphocyte chemotactic factor. Interleukin-8 is a chemoattractant for neutrophils, basophils, and a subset of T cells. It is produced by a majority of nucleated cells that include macrophages, fibroblasts, endothelial and epithelial cells exposed to TNF. , IL-1a, IL-1β or LPS, and by neutrophils themselves when exposed to LPS or chemotactic factors such as FMLP. M. Baggiolini et al., J. Clin. Invest. 84, 1045 (1989); J. Schroder et al., J. Immunol. 139, 3474 (1987) and J. Immunol. 144. 2223 (1990); Strieter et al., Science 243, 1467 (1989) and J. Biol. Chem. 264, 10621 (1989); Cassatella et al., J. Immunol. 148, 3216 (1992). GROa, GROß, GRO? and NAP-2 also belong to the family chemokine. Similar to IL-8, these chemokines have been referred to by different names. For example GROa, ß,? have been referred to as MGSAa, ß and? respectively (Growth Stimulating Activity of Melanoma or Growth Stimulating Activity Melanoma), see Richmond et al., J. Cell Physiology 129, 375 (1986) and Chang et al., J. Immunol 148, 451 (1992). All chemokines in the family that possess the ELR motif directly preceding the CXC motif bind to the IL-8B receptor. IL-8, GROa, GROß, GRO ?, NAP-2 and ENA-78 stimulate a number of functions in vitro. All of them have been shown to have chemoattractant properties for neutrophils, whereas IL-8 and GROa have demonstrated chemotactic activity of basophils and T-lymphocytes. In addition IL-8 can induce histamine release from basophils of both normal and atopic individuals. GRO-a and IL-8 may also induce lysozomal enzyme release and neutrophil respiratory bursts. IL-8 has also been shown to increase surface expression of Mac-1 (CD11 b / CD18) on neutrophils without de novo protein synthesis. This may contribute to increased adhesion of neutrophils to vascular endothelial cells. Many known diseases are characterized by massive infiltration of neutrophils. Like IL-8, Groa, GROß, GRO? and NAP-2 promote the accumulation and activation of neutrophils, these chemokines have been implicated in a wide range of acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis, Baggiolini et al., FEBS Lett. 307, 97 (1992); Miller et al., Crit. Rev. Immunol. 12, 17 (1992); Oppenheim et al., Annu. Rev. Immunol. 9. 617 (1991); Seitz et al., J. Clin. Invest. 87, 463 (1991); Miller et al., Am. Rev. Respir. Dis 146, 427 (1992); Donnely et al., Lancet 341, 643 (1993). In addition, ELR chemokines (those that contain the ELR motif of amino acids just before the CXC motif) have also been implicated in angiostasis. Strieter et al., Science 258, 1798 (1992). In vitro, IL-8, GROa, GROß, GRO? and NAP-2 induce neutrophil shape change, chemotaxis, granule release, and respiratory bursts, binding to and activating receptors of the seven-transmembrane family, chained to G protein, particularly binding to IL-8 receptors, most notably the receptor B. Thomas et al., J. Biol. Chem. 266, 14839 (1991); v Holmes et al., Science 253, 1278 (1991). The development of non-peptide small molecule antagonists for members of this recipient family is unprecedented. For a summary consult R. Freidinger in: Proqress in Drug Research, Vol. 40, pp. 33-98, Birkhauser Verlag, Basel 1993. Hence, the IL-8 receptor represents a promising target for the development of new anti-inflammatory agents. Two IL-8 receptors of high human affinity (77% homology) have been characterized: IL-8Ra, which binds only to IL-8 with high affinity, and IL-8Rβ, which has high affinity for IL-8 as well as for GRO-a, GROß, GRO? and NAP-2. See Holmes et al., Supra; Murphy et al., Science 253. 1280 (1991); Lee et al., J. Biol. Chem. 267, 16283 (1992); LaRosa et al., J, Biol. Chem. 267. 25402 (1992); and Gayle et al., J. Biol. Chem. 268. 7283 (1993). There remains a need for treatment, in this field, for compounds that are capable of binding the IL-8 a or β receptor. Therefore, conditions associated with an increase in the production of IL-8 (which is responsible for chemotaxis of neutrophils and subsets of T cells in the inflammatory site) would benefit by compounds that are inhibitors of IL-8 receptor binding.

Method of treatment The compounds of the formula (I), or a pharmaceutically acceptable salt thereof, can be used in the manufacture of a medicament for the prophylactic or therapeutic treatment of any disease state in a human, or other mammal, which it is exacerbated or caused by an excessive or unregulated production of cytosine IL-8 by said mammalian cell, such as but not limited to monocytes and / or macrophages, or other chemokines that bind to the IL-8 a or β receptor, as well referred to as the type I or type II receiver. Accordingly, the present invention provides a method of treating a disease mediated by chemokine, wherein the chemokine is that which binds to an IL-8 a or β receptor and which method comprises the administration of an effective amount of a compound of the formula I or a pharmaceutically acceptable salt thereof. In particular, the chemokines are IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78. The compounds of the formula (I) are administered in an amount sufficient to inhibit the function of the cytosine, in particular IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78, so that they are regulated biologically to normal levels of physiological function, or in certain case at normal levels, to improve the state of the disease. The abnormal levels of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 for example in the context of the present invention, constitute: i) levels of free IL-8 greater than or equal to one picogram per ml; ii) any associated cell IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 of the above normal physiological levels; or iii) the presence of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 of the previous basal levels in cells or tissues in which respectively IL-8, GROa, GROß, GRO? NAP-2 or ENA-78. There are several disease states in which the production of excessive or unregulated IL8 is involved in the exacerbation and / or provocation of the disease. Chemokine-mediated diseases include psoriasis, atopic dermatitis, arthritis, asthma, chronic obstructive pulmonary disease, respiratory distress syndrome in adults, inflammatory bowel disease, Crohn's disease, ulcerative colitis, infarction, septic shock, endotoxic shock, gram-negative sepsis , toxic shock syndrome, cardiac and renal reperfusion injury, glumerulonephritis, thrombosis, graft-versus-host reaction, Alzheimer's disease, allograft rejections, malaria, restinosis, angiogenesis or unwanted release of hematopoietic stem cells, rhinovirus infections, and several indications of bone resorption, such as osteoporisis or osteoarthritis. The association of interleukin-8 and rhinovirus can be found in articles such as: Turner, et al., Clin. Infect. Dis. (1988), 26 (4), 840-846; Sanders, et al., J. Vitral. (1998), 72 (2), 934-942; Sethi, et al., Clin. Exp. Immunol, (1997), 110 (3), 362-369, Zhu et al., Am. J. Physiol. (1997), 273 (4, Pt. 1), L814-L824; Terajima, et al., Am. J. Physiol. (1997), 273 (4, Pt. 1), L749-L759; Grunberg, et al., Clin. Exp. Allergy (1997), 27 (1), 36-45; and Johnson, et al., J. Infecí. Dis. (1997), 175 (2), 323-329. The association of interleukin -8 and osteoporosis can be found in articles such as: Streckfus at al., J. Gerontol., Ser. A (1997), 52A (6), M343-M351; Hermann, T. WO95 / 31722; and Chaudhary, et al., Endocrinology (Baltimore) (1992), 130 (5), 2528-34. These diseases are characterized mainly by massive neutrophil infiltration, T cell infiltration, or neovascular growth, and are associated with the production of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 which is responsible for the chemotaxis of neutrophils in the inflammatory site or the directional growth of endothelial cells. In contrast to other inflammatory cytokines (IL-8, GROa, GROß, GRO? Or NAP-2), it has the unique property of promoting chemotaxis of neutrophils, releasing from above including but not limited to the release of elastase as well as to the production and activation of superoxide. The a-chemokines, but particularly, GROa, GROß, GRO? or NAP-2, which work in the IL-8 type I or II receptor can promote neovascularization of tumors by promoting the directional growth of endothelial cells. Therefore, inhibition of the induced chemotaxis of IL-8 or activation can lead to a direct reduction in neutrophil infiltration. Recent evidence also implicates the role of chemokines in the treatment of HIV infections, Littieman et al., Nature 381, pp, 661 (1996) and Koup et al., Nature 381, pp, 667 (1996). The present invention also provides a means of treatment, in acute fixation, as well as prevention, in those individuals susceptible to CNS damage by the chemokine receptor antagonist compounds of the formula (I). CNS damage, as defined herein, includes open-head or penetrative trauma, such as surgery, or a damage from closed-head trauma, such as damage to the head region.
- ----------- Also included in this definition is ischemic infarction, particularly the brain area. Ischemic infarction can be defined as a focal neurological disorder that results from insufficient blood supply to a particular area of the brain, usually as a result of an embolus, thrombus, or local anesthetic closure of the blood spleens. The role of inflammatory cytokines in that area has arisen and the present invention provides a means for the potential treatment of such damages. Relatively low treatment, for acute damage such as the above, have been available. Current evidence also indicates the use of IL-8 inhibitors in the treatment of atherosclerosis. The first reference, Boisvert et al., J. Clin. Invest., 1998, 101: 353-363 shows, through bone marrow transplantation, that the absence of IL-8 receptors in stem cells (and, therefore, in monocytes / macrophages) leads to a reduction in the development of atherosclerotic plaques in mice deficient in LDL receptor.

FNT-a is a cytokine with proinflammatory actions, including the expression of endothelial leukocyte adhesion molecules. The leukocytes infiltrate the ischemic lesions of the brain and therefore the compounds that inhibit or reduce the levels of TNF are useful for the treatment of cerebral ischemic damage. See Liu et al., Stoke, Vol. 25., No. 7, pp. 1481-88 (1994), the description of which is incorporated herein by reference. Models of closed head injuries and treatment with mixed 5-LO / CO agents are described in Shohami et al., J. of Vaisic & Clinical Physiology and Pharmacology, Vol. 3, No. 2, pp. 99-107 (1992), the disclosure of which is incorporated herein by reference. It was found that the treatment that reduces the formation of edema improves the functional result in said treated animals. The compounds of formula (I) are administered in an amount sufficient to inhibit IL-8, bind to IL-8 alpha or beta receptors, from which they bind to said receptors, as evidenced by a reduction in the chemotaxis and activation of neutrophils. The discovery that the compounds of the formula (I) are inhibitors of the IL-8 binding is based on the effects of the compounds of the formulas (I) on the in vitro receptor binding assays described herein. The compounds of the formula (I) have been shown to be inhibitors of IL-8 type II receptors. As used herein, the term "disease or disease state mediated by IL-8" refers to any disease state in which IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 has a role, either through the production of IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78 themselves, or by IL-8, GROa, GROß, GRO ?, NAP-2 or ENA 78 that cause that another monocyte be released, such as but not limited to IL-1, IL-6 or FNT. A disease state in which, for example, IL-1 is a major component, and whose production or action is exacerbated or secreted in response to IL-8, is therefore considered to be a disease state mediated by IL-8 . As used herein, the term "disease or disease state mediated by chemokine" refers to any disease state in which a chemokine that binds to an IL-8 a or β receptor has a role, such but not limited to to IL-8, GROa, GROß, GRO ?, NAP-2 or ENA-78. The above includes a disease state in which IL-8 has a function, either in the production of IL-8 itself, or IL-8 which causes the release of another monocycline, such as but not limited to IL-1, IL-6 or FNT. A disease state in which, for example, IL-1 is a major component, and whose production or action is exacerbated or secreted in response to IL-8, will therefore be considered a disease state mediated by IL-8. . As used herein, the term "cytokine" refers to any secreted polypeptide that affects the functions of cells and is a molecule that modulates the interactions between cells in the inflammatory or hematopoietic immune response. A cytokine includes, but is not limited to, monocytes and lymphokines, despite the cells that produce them. For example, reference is generally made to the fact that a monocline is produced and secreted by a mononuclear cell, such as a macrophage and / or monocyte. Several other cells, however, also produce monocins, such as natural killer cells, fibroblasts, basophils, neutrophils, endothelial cells, brain astrocytes, bone marrow stromal cells, epidermal keratinocytes and B-lymphocytes. Lymphokines are generally referred to as being produced by lymphocyte cells. Examples of cytokines include, but are not limited to, interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-a) and tumor necrosis factor beta (TNF-β). As used herein, the term "chemokine" refers to any secreted polypeptide that affects the functions of cells and is a molecule that modulates the interactions between cells in the immune, inflammatory or hematopoietic response, similar to the term "cytokine" "previous. A chemokine is secreted primarily through cell transmembranes and causes chemotaxis and activation of specific white blood cells and leukocytes, neutrophils, monocytes, macrophages, T cells, B cells, endothelial cells and smooth muscle cells. Examples of chemokines include, but are not limited to, IL-8, GRO-a, GRO-β, GRO- ?, NAP-2, ENA-78, IP-10, MIP-1a, MlP-β, PF4, and MCP 1, 2 and 3. In order to use a compound of formula (I) or a pharmaceutically acceptable salt thereof in therapy, it will normally be formulated into a pharmaceutical composition in accordance with standard pharmaceutical practice. This invention, therefore, also relates to a pharmaceutical composition comprising an effective, non-toxic amount of a compound of formula (I) and a pharmaceutically acceptable carrier or diluent. The compounds of the formula (I), pharmaceutically acceptable salts thereof and pharmaceutical compositions incorporating said compounds can be conveniently administered by any of the routes conventionally used for the administration of drugs, for example, orally, topically, parenterally or by inhalation . The compounds of formula (I) can be administered in the form of conventional doses prepared by the combination of a compound of formula (I) with standard pharmaceutical carriers according to conventional procedures. The compounds of formula (I) can also be administered in conventional doses in combination with a second known therapeutically active compound. Such procedures may involve mixing, granulating and compressing or dissolving the ingredients as appropriate for the desired preparation. It will be appreciated that the form and character of the pharmaceutically acceptable character or diluent is dictated by the amount of active ingredient with which it is combined, the route of administration and other well-known variables. The carriers must be "acceptable" in the sense that they must be compatible with the other ingredients of the formulation and not harmful to the recipient thereof.
The pharmaceutical carrier used can be, for example, a solid or a liquid. Examples of solid carriers are lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, stearic acid and the like. Examples of liquid carriers are syrup, peanut oil, olive oil, water and the like. Similarly, the carrier or diluent may include time delay material well known in the art, such as glyceryl monostearate or glyceryl distearate alone or with a wax. A wide variety of pharmaceutical forms can be used. Thus, if a solid carrier is used, the preparation can be converted into tablets, placed in a hard gelatin capsule in powder or pellet form or in the form of a troche or tablet. The amount of solid carrier will vary widely, but will preferably be from about 25 mg to about 1 g. When a liquid carrier is used, the preparation will be in the form of a syrup, emulsion, soft gelatin capsule, sterile injectable liquid such as a suspension of ampoule or non-aqueous liquid. The compounds of formula (I) can be administered topically, i.e. by non-systemic administration. The above includes the application of a compound of formula (I) externally to the epidermis or the oral cavity and the installation of said compound in the ear, eyes and nose, so that the compound does not significantly enter the bloodstream. In contrast, systemic administration refers to oral, intravenous, intraperitoneal and intramuscular administration.
Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin to the site of inflammation such as liniments, lotions, creams, ointments or pastes, and drops suitable for administration to eyes, ears or nose The active ingredient may comprise, for topical administration, from 0.001% to 10% w / w, for example from 1% to 2% by weight of the formulation. It can, however, comprise up to 10% w / w, but preferably it will comprise less than 5% w / w, more preferably from 0.1% to 1% w / w of the formulation. Lotions according to the present invention include those suitable for application to the skin or eyes. An eye lotion may comprise a sterile aqueous solution optionally containing a bactericide and may be prepared by methods similar to those for the preparation of drops. Lotions or liniments for application to the skin may also include an agent for accelerating the drying and cooling of the skin, such as an alcohol or acetone, and / or a humectant such as glycerol or an oil such as castor oil. or arachis oil. Creams, ointments or pastes according to the present invention are semisolid formulations of the active ingredient for external application.

BIOLOGICAL EXAMPLES The chemokine inhibitory effects of IL-8, and GRO-a of the compounds of the present invention are determined by the following in vitro assay: Receptor binding assays: [125I] IL-8 (human recombinant) is obtained from Amersham Corp., Arlington Heights, IL, with specific activity of 2000 Ci / mmoles. The Gro-a is obtained from NEN-New England Nuclear. All other chemicals are analytical grade. High levels of recombinant human IL-8 type receptors a and β were individually expressed in Chinese hamster ovary cells as previously described (Holmes, et al., Science, 1991, 253, 1278). The Chinese hamster ovary membranes were homogenized according to the protocol described above (Haour, et al., J Biol Chem., 249 pp. 2195-2205 (1974)) Except that the homogenization pH regulator was changed to 10mm. of tris-HCL, 1 mm of MgSO4, 0.5 mm of EDTA (ethylenediaminetetraacetic acid), 1 mm of PMSF (a-toluenesulfonyl fluoride), 0.5 mg / L of leupeptin, pH 7.5 The concentration of membrane proteins is determined using The Pierce Co. microassay kit using bovine serum albumin as a standard All assays were carried out in a 96-well microplate format Each reaction mixture contains 125 I-IL-8 (0.25 Nm) O / 125 I Gro-a and 0.5 μg / ml of IL-8Ra or 1.0 μg / ml of membranes and IL-8Rβ in 20 mm of Bis-Trispropane and 0.4 mm of pH regulators of Tris HCl, Ph 8.0, containing 1.2mm of MgSO4, 0.1 mm of EDTA, 25 mm of NaCl, and 0.03% of CHAPS In addition, the drug or compound of interest is added, which has been pre-dissolved in DMSO to reach a final concentration between 0.01 nM and 100 uM. The assay was initiated by the addition of 125 I-IL-8. After 1 hour at room temperature, the plate was cultured using a Tamtec 96-well harvester on a glass fiber filter blocked with 1% polyethyleneimine-0.5% BSA and washed 3 times with 25 mm NaCl, 10 mm TrisHCI, 1 mm MgSO4, 0.5 mm EDTA, 0.03% CHAPS, pH 7.4. The filter was then dried and counted in the liquid scintillation counter of beta plate. The IL-8 receptor Ra, recombinant, or type I, is also referred to herein as the non-permissive receptor and reference is made to the IL-8Rβ receptor, recombinant, or type II, as the permissive receptor. It has been found that representative compounds of formula (I), examples 1 to 8, have positive inhibitory activity of < 30 μmg in this assay.
Chemotaxis Assay The in vitro inhibitory properties of said compounds are determined in the neutrophil chemotaxis assay as described in Current Protocols in Immunology, vol. I, Suppl 1, Unit 6.12.3, the description of which is incorporated herein by reference in its entirety. Neutrophils were isolated from human blood as described in Current Protocols in Immunology Vol. I, Sup / 1. 1 Unit 6: 12.3, the description of which is incorporated herein by reference in its entirety. The chemoattractants IL-8, GRO-a, GRO-β, GRO-? and NAP-2 are placed in the lower chamber of a 48-cavity multi-chamber (Neuro Probé, Cabin John, MD) at a concentration between 0.1 and 100 nM. The two chambers are separated by a polycarbonate filter of 5 um. When testing the compounds of this invention, they are mixed with the cells (0.001-1000 nM) just before the addition of the cells in the upper chamber. The incubation can proceed from between about 45 and 90 min at about 37 ° C in a humidified incubator --- ^ '. - .. ra --- -fc. , with 5% CO2. At the end of the incubation period, the polycarbonate membrane is removed and the upper area is washed, the membrane is then stained using the Diff Quick staining protocol (Baxter Products, McGaw Park, IL, E.U.A). The cells that underwent chemotaxis to chemokine are counted visually using a telescope. Generally, 4 fields are counted for each sample, these numbers are averaged to give the average number of cells that have migrated. Each sample is tested in triplicate and each compound is repeated at least 4 times. For certain cells (positive control cells), no compound was added, said cells represent the maximum chemotactic response of the cells. In the case where a negative (unstimulated) control is desired, chemokine is not added to the lower chamber. The difference between the positive control and the negative control represents the chemotactic activity of the cells.
Elastase Release Assay The compounds of this invention were tested for their ability to prevent the release of elastase from human neutrophils. Neutrophils are isolated from human blood as described in Current Protocols in Immunology Vol. I. Suppl 1 Unit 7.23.1. PMNs 0.88 x 106 cells suspended in Ringer's solution (NaCI 118, KCl 4.56, NaHCO3 25, KH2PO4 1.03, glucose 11.1, HEPES 5 mm, pH 7.4) are placed in each well of a 96-well plate in a volume of 50 ul. To this plate is added the test compound (0.001 - 1000 nM) in a volume of 50 ul, the cytochalasin B in a volume of 50 ul (20ug / ml) and the Ringer's pH regulator in a volume of 50ul. Said cells could be heated (37 ° C, 5% CO2.95% RH) for 5 min. before it was added IL-8 GROa, GROß.GRO? or NAP-2) at a final concentration of 0.01-1000 mM. The reaction could proceed for 45 min. before a 96-well plate (800 xg 5 min.) and 100 ul of the removed supernatant were centrifuged. Said supernatant was added to a second 96-well plate followed by an artificial elastase substrate (MeOSuc-Ala-Ala-Pro-Val-AMC, Nova Biochem, La Jolla, CA) at a final concentration of 6 mg / ml dissolved in Saline regulated phosphate solution. Immediately, the plate was placed in fluorescent 96-well plate reader (Cytofluor 2350, Millipore, Bedford, MA) and data were collected at 3 min intervals. according to the method of Nakajima et al J. Biol Chem 254 4027 (1979). The amount of elastase released from the PMNs is calculated by measuring the degradation rate of MeOSuc-Ala-Ala-Pro-Val-AMC.
FNT-a assay in traumatic brain injury This trial provides the examination of the expression of tumor necrosis factor mRNA in specific brain regions that follow traumatic brain injury from experimentally induced lateral fluid percussion (TBI) in rats since FNT- a is able to induce nerve growth factor (NGF) and stimulates the release of other cytokines from activated astrocytes, said post-traumatic alteration in the expression of the FNT-a gene plays an important role in the acute and regenerative response for the CNS trauma. A suitable assay can be found in WO 97/35856 or WO 97/49286, the descriptions of which are incorporated herein by reference.
CNS damage model for IL-ß mRNA. This assay characterizes the regional expression of interlucin-1β mRNA (IL-1β) in specific brain regions following traumatic brain injury from experimental lateral fluid percussion (TBI) in rats. The results of these tests indicate that following the TBI, the temporal expression of IL-1β mRNA is regionally stimulated in specific brain regions. Such regional changes in cytokines, ethers such as IL-1β play a role in post-traumatic pathological or regenerative sequelae of brain damage. A suitable assay can be found in WO 97/35856 or WO 97/49286, the descriptions of which are incorporated herein by reference.

Sectioning and staining of the aortic sinus The transverse sections of the aortic root are taken as previously described (1, 2). Briefly, the hearts are bisected just below the level of the atria and the base of the heart plus the aortic root are taken for analysis. After balancing the tissue in the OCT compound during the night, the hearts are immersed in the OCT compound in a cryostat mandrel (Bright Instrument Company Ltd., R.U) with the aorta facing the mandrel. The tissue freezes when surrounding the mandrel with dry ice. The hearts are then sectioned perpendicular to the axis of the aorta, starting at the heart and working in the direction of the aorta. Once the aortic root has been identified by the appearance of three valve leaflets, alternate 10mm sections are taken and mounted on gelatinized slides. The sections are air-dried for 1 hour and subsequently briefly rinsed in 60% sopropyl alcohol. The sections are stained with oil red O, counterstained with Mayer's hematoxylin, covered using glycerol gelatin and sealed with nail varnish.
Quantification of atherosclerosis in the aortic root. Ten alternate sections of the aortic root are observed using an Olympus BH-2 microscope equipped with a 4x objective and a video camera (Hitachi, HV-C10). 24-bit color images are acquired and analyzed using a PC (Datacell Pentium P5-133, Datacell Berks, R.U) coupled with a frame recording board (Snapper.Active Imaging Ltd, Berks, R.U) and runs the software Optimus (version 5.1, Optimums Corp., WA, E.U.A). The images were captured under identical conditions of the microscopes, camera and PC. The quantification of the atherosclerotic lesion areas is carried out by hand drawing around the lesion using the Optimas software. The three colors are set to quantify the areas that are stained red in the lesions. The absolute values for the cross-sectional areas of the lesions and the areas stained red are obtained by software calibration using a grid image on a hemocytometer slide.
