Definitions
- This invention relates to novel benzoisothiazole substituted compounds, pharmaceutical compositions, processes for their preparation, and use thereof in treating LL-8, GRO ⁇ , GRO ⁇ , GRO ⁇ and NAP-2 mediated diseases.
- Interleukin-8 Interleukin-8
- NAP-1 neutrophil attractant/activation protein- 1
- MDNCF monocyte derived neutrophil chemotactic factor
- NAP neutrophil activating factor
- T-cell lymphocyte chemotactic factor 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 including macrophages, fibroblasts, endotheliai and epithelial cells exposed to TNF, IL-l ⁇ , IL-l ⁇ or LPS, and by neutrophils themselves when exposed to LPS or chemotactic factors such as FMLP. M.
- GRO ⁇ , GRO ⁇ , GRO ⁇ and NAP-2 also belong to the chemokine ⁇ family. Like IL-8, these chemokines have also been referred to by different names. For instance GRO ⁇ , ⁇ , ⁇ have been referred to as MGSA ⁇ , ⁇ and ⁇ respectively
- IL-8, GRO ⁇ , GRO ⁇ , GRO ⁇ , NAP-2 and ENA-78 stimulate a number of functions in vitro. They have all been shown to have chemoattractant properties for neutrophils, while IL-8 and GRO ⁇ have demonstrated T-lymphocytes, and basophilic chemotactic activity.
- LL-8 can induce histamine release from basophils from both normal and atopic individuals
- GRO- ⁇ and IL-8 can in addition, induce lysozomal enzyme release and respiratory burst from neutrophils.
- IL-8 has also been shown to increase the surface expression of Mac- 1 (CD1 lb/CD 18) on neutrophils without de novo protein synthesis. This may contribute to increased adhesion of the neutrophils to vascular endothelial cells. Many known diseases are characterized by massive neutrophil infiltration.
- GRO ⁇ , GRO ⁇ , 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. Pis. 146.
- ELR chemokines (those containing the amino acids ELR motif just prior to the CXC motif) have also been implicated in angiostasis, see Strieter et al., Science 258, 1798 ( 1992).
- IL-8, GRO ⁇ , GRO ⁇ , GRO ⁇ and NAP-2 induce neutrophil shape change, chemotaxis, granule release, and respiratory burst, by binding to and activating receptors of the seven-transmembrane, G-protein-linked family, in particular by binding to IL-8 receptors, most notably the B-receptor. Thomas et al., J. Biol. Chem. 266. 14839 (1991); and Holmes et al., Science 253. 1278 (1991).
- the development of non-peptide small molecule antagonists for members of this receptor family has precedent. For a review see R. Freidinger in: Progress in Drug Research. Vol. 40, pp. 33-98, Birkhauser Verlag, Basel 1993.
- the LL-8 receptor represents a promising target for the development of novel anti-inflammatory agents.
- IL-8R ⁇ which binds only IL-8 with high affinity
- LL-8R ⁇ which has high affinity for IL-8 as well as for GRO- ⁇ , GRO ⁇ , GRO ⁇ and NAP-2.
- IL-8R ⁇ which binds only IL-8 with high affinity
- LL-8R ⁇ which has high affinity for IL-8 as well as for GRO- ⁇ , GRO ⁇ , GRO ⁇ and NAP-2.
- This invention provides for a method of treating a chemokine mediated disease, wherein the chemokine is one which binds to an IL-8 ⁇ or ⁇ receptor and
- chemokine is IL-8.
- This invention also relates to a method of inhibiting the binding of IL-8 to its receptors in a mammal in need thereof which comprises administering to said mammal an effective amount of a compound of Formula (I) or (II).
- the present invention also provides for the novel compounds of Formula (I), and (II) and pharmaceutical compositions comprising a compound of Formula (I), and (II) and a pharmaceutical carrier or diluent.

- In vivo - athereoschlerosis assay In vivo models for measuring atherosclerosis in mice is based on the assay of Paigen et al with small modifications as described below. See Paigen B, Morrow A, Holmes PA, Mitchell D, Williams RA. Quantitative assessment of atherosclerotic lesions in mice. Atherosclerosis 68: 231-240 (1987); and Groot PHE, van Vlijmen BJM, Benson GM, Hofker MH, Schiffelers R, Vidgeon-Hart M, Havekes LM. Quantitative assessment of aortic atherosclerosis in APOE*3 Leiden transgenic mice and its relationship to serum cholesterol exposure. Arterioscler Thromb Vase Biol. 16: 926-933 (1996). Sectioning and staining of the aortic sinus
- Cross-sections of the aortic root are taken as has been described previously (1,2). Briefly, the hearts are bisected just below the level of the atria and the base of the heart plus aortic root are taken for analysis. After equilibrating the tissue in OCT compound overnight the hearts are immersed in OCT compound on a cryostat chuck (Bright Instrument Company Ltd., UK) with the aorta facing the chuck. The tissue is frozen by surrounding the chuck with dry ice. The hearts are then sectioned perpendicular to the axis of the aorta, starting within the heart and working in the direction of the aorta.
- Ten alternate sections of the aortic root are imaged using an Olympus BH-2 microscope equipped with an 4x objective and a video camera (Hitachi, HV-C10). Twenty-four bit colour images are acquired and analysed using a PC (Datacell Pentium P5-133, Datacell, Berks, U.K.) fitted with a framegrabbing board (Snapper, Active Imaging Ltd, Berks. U.K.) and running Optimas software (version 5.1, Optimas Corp., WA, U.S.A.). The images are captured under identical lighting, microscope, camera and PC conditions. Quantification of the atherosclerotic lesion areas is performed by drawing around the lesions by hand using the Optimas software. Colour thresholds are set that quantify the areas that are stained red within the lesions. Absolute values for the cross-sectional areas of the lesions and the areas stained red are obtained by calibrating the software using an image of the grid on a haemocytometer slide.
