Definitions
- the subject of the invention is quinazolinedione derivatives, their production processes, their synthetic intermediates and their therapeutic applications.
- the invention relates to quinazolinedione derivatives, which may be phosphodiesterase 7 inhibitors (abbreviated as PDE7). Some of these derivatives may also inhibit phosphodiesterase 8 (abbreviated PDE8).
- PDE7 phosphodiesterase 7 inhibitors
- PDE8 phosphodiesterase 8
- the invention also relates to the use of such quinazolinedione derivatives, which may act as phosphodiesterase 7 (PDE7) inhibitors, or, for some of these derivatives, which may also act as inhibitors of phosphodiesterase 8 (PDE8), knowing that it is not excluded that these same quinazolinedione derivatives are also likely to act via other biological / biochemical pathways.
- PDE7 phosphodiesterase 7
- PDE8 phosphodiesterase 8
- Phosphodiesterases are intracellular enzymes responsible for the hydrolysis of cAMP (cyclic adenosine-3 ', 5 1 -monophosphate) and cGMP (cyclic guanosine-3', 5'-monophosphate) secondary messengers into 5'-monophosphate nucleotides. inactive. CAMP and cGMP play a vital role in cell signaling pathways and are involved in many physiological processes.
- Phosphodiesterase inhibitors are therefore of interest as therapeutic agents and as pharmacological tools.
- eleven families of phosphodiesterases have been identified. They are distinguished by their primary structure, their substrate specificity and their sensitivity to various specific PDE effectors and inhibitors. Each family consists of one or more genes that are expressed in different tissues as splice variants (Bender and Beavo, Pharmacol Rev (2006) 58, 488-520, Lugnier, Pharmacol Therapeut (2006) 109, 366- 398).
- PDE4, 7, and 8 specifically hydrolyze cAMP and PDE5, 6 and 9 CGMP.
- the PDE7 family is represented by the PDE7A and PDE7B isoforms, from two distinct genes.
- Human PDE7A (Michaeli et al., J. Biol Chem (1993) 268, 12925-12932, Han et al., J. Biol Chem (1997) 272, 16152-16157, Wang et al., Biochem Biophys Res Commun (2000) 276, 1271 -1277) and human PDE7B (Sasaki et al., Biochem Biophys Res Commun (2000), 271, 575-583, Gardner et al, Biochem Biophys Res Commun (2000) 272, 186-192) selectively hydrolyze cAMP with Michaelis constant (Km) 0.1 to 0.2 ⁇ M and 0.13 to 0.2 ⁇ M, respectively.
- the catalytic portion of PDE7B has about 67% homology with that of PDE7A.
- PDE7A1 and PDE7A3 are mainly expressed in the cells of the immune system and the lungs, whereas PDE7A2 is mainly expressed in skeletal, heart and kidney muscles.
- PDE7B three variants have also recently been identified (Giembycz and Smith, Drugs Future (2006) 31, 207-229).
- PDE7A and PDE7B are very different suggesting that these two isoforms have physiologically distinct functions. While PDE7A is abundantly expressed in hematopoietic cells, lungs, placenta, Leydig cells, spleen, kidney and adrenal tubules, strong PDE7B expression is detected in the pancreas, heart, thyroid and skeletal muscles (Giembycz and Smith, Drugs Future (2006) 31, 207-229).
- PDE7 The localization of PDE7 at the organs mentioned above suggests that selective PDE7 inhibitors could have applications in the field of muscular, renal, cardiac and pancreatic diseases such as in the treatment and / or prevention of diabetes.
- RNAm messenger RNA
- PDE7A and PDE7B coexpression of the messenger RNA (RNAm) of PDE7A and PDE7B is observed in some tissues. This is the case in osteoblasts (Ahlstrom et al., CeII Mol Biol Lett (2005) 10, 305-319) and in certain regions of the brain: several areas of the cortex, the dentate gyrus, most of the components of the olfactory system, the striatum, numerous thalamus nuclei and pyramidal cells of the hippocampus (Miro et al, Synapse (2001) 40, 201-214, Reyes-Irisarri et al, Neuroscience (2005) 132, 1173-1185). In some areas of the brain, however, only one of the two isoforms is expressed.
- PDE7A RNAm are present in many brainstem nuclei.
- PDE7B RNAm are present in high concentrations in the nucleus accumbens and the motor dorsal nucleus of the vagus nerve whereas the PDE7A RNAm are not detected there (Miro et al, Synapse (2001) 40, 201-214; Reyes-lrisarri et al., Neuroscience (2005) 132, 1173-1185).
- PDE7A1 protein is well expressed in blood T lymphocytes, bronchial epithelial cell lines, lung fibroblasts and eosinophils (Smith et al., Am J Physiol Lung CeII Mol Physiol (2003) 284: L279-L289).
- PDE7A may play a role in T cell activation (Li et al, Science (1999) 283, 848-851, Glavas et al, PNAS (2001) 98, 6319-6324, Nakata et al, Clin Exp Immunol, (2002) 128, 460-466 Smith et al, Mol Pharmacol (2004) 66, 1679-1689).
- PDE7A1 protein is also expressed in cells that play a central role in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD), such as T cells (CD4 + and CD8 +), monocytes, neutrophils, alveolar macrophages, smooth muscle cells of the airways and pulmonary vessels (Smith et al., Am J Physiol Lung CeII Mol Physiol (2003) 284: L279-L289).
- COPD chronic obstructive pulmonary disease
- PDE7A is also present in B cells and in the WSU-CLL B cell line from a patient with chronic lymphocytic leukemia.
- PDE7B protein expression is approximately 5 to 90-fold higher in peripheral blood mononuclear cells (PBMCs) of patients with chronic lymphocytic leukemia (CLL-PBMC) than in isolated PBMCs. blood from normal subjects (WO 2007/067946).
- PBMCs peripheral blood mononuclear cells
- CLL-PBMC chronic lymphocytic leukemia
- BRL-50481 a selective PDE7 inhibitor, dose-dependently induces CLL-PBMC apoptosis but has no effect on PBMCs in normal subjects.
