Definitions
- the present invention relates to novel chemical compounds, heterocyclic carbazole derivatives, compositions containing them, and their use as medicaments.
- the invention relates, according to a first aspect, to novel heterocyclic carbazole derivatives exhibiting anticancer activity, and in particular to an inhibitory activity of the Hsp90 chaperone protein, and more particularly via the inhibition of the catalytic activity of the type. ATPase of the chaperone protein Hsp90.
- HSPs Heat Shock Proteins
- Hsp27, Hsp70, Hsp90 The molecular chaperones of the "Heat Shock Proteins” (HSPs) family, classified according to their molecular mass (Hsp27, Hsp70, Hsp90 ).
- HSPs Heat Shock Proteins
- Hsp90 are key elements of the balance between the synthesis and the degradation of cellular proteins. , responsible for the correct folding of proteins. They play a vital role in response to cellular stress.
- HSPs, and in particular Hsp90 are also involved in the regulation of various major functions of the cell, via their association with various client proteins involved in cell proliferation or apoptosis (JoIIy C. and Morimoto RI, JN Cancer Inst. (2000), 92, 1564-72, Smith DF et al., Pharmacological Rev. (1998), 50, 493-513, Smith DF, Molecular Chaperones in the CeII, 165-178,
- Hsp90 and Hsp90 Inhibitors for the Treatment of Cancers The Hsp90 chaperone, which accounts for 1-2% of the protein content of the cell, has recently been identified as a particularly promising target in anticancer therapy (see review for Moloney A and Workman P., Expert Opin Biol Ther (2002), 2 (1), 3-24, Chiosis et al, Drug Discovery Today (2004), 9, 881-888). This interest is particularly related to the cytoplasmic interactions of Hsp90 with the main Hsp90 client proteins, which are involved in the six tumor progression, as defined by Hanahan D. and Weinberg RA (CeII (2002), 100, 57-70), namely:
- VEGF-R an ability to activate angiogenesis: VEGF-R, FAK, HIF-1, Akt ...
- Hsp90 steroid hormone receptors, such as the estrogen receptor or the androgen receptor, are also of great interest in the context of anticancer therapies. It has been recently shown that the alpha form of Hsp0O also has an extracellular role via its interaction with the metalloprotease MMP-2, itself involved in tumor invasion (Eustace BK et al., Nature CeII Biology (2004), 6). , 507-514). Hsp90 consists of two N- and C-terminal domains separated by a highly charged region. The dynamic interaction between these two domains, coordinated by the fixation of nucleotides and co-chaperones, determines the conformation of the chaperone and its activation state.
- the association of client proteins mainly depends on the nature of the co-chaperones Hsp70 / Hsp40, Hop ⁇ O etc ... and the nature of the ADP or ATP nucleotide linked to the N-terminal domain of Hsp90.
- the hydrolysis of ATP to ADP and the ADP / ATP exchange factor control all of the chaperone "machinery", and it has been shown that it is sufficient to prevent the hydrolysis of ATP to ADP.
- Alzheimer's Disease and Multiple Sclerosis These diseases are due in part to the expression of pro-inflammatory cytokines and the inducible form of NOS (Nitric oxide synthase) in the brain, and this expression is suppressed by the answer to stress.
- NOS Nitric oxide synthase
- the Hsp90 inhibitors are capable of garnering this stress response, and it has been shown in vitro that geldanamycin and 17-AAG exhibit anti-inflammatory activity in brain glial cells (J. Neuroscience Res. : 461, 2002).
- Amyotrophic lateral sclerosis This neurodegenerative disease is due to the progressive loss of motor neurons.
- Arimoclomol an inducer of heat-shock proteins, has been shown to delay the course of disease in an animal model (Nature Medicine 10: 402, 2004). Since an Hsp0O inhibitor is also an inducer of heat-shock proteins (Mol., Cell Biol., 19: 8033, 1999; Mol. CeII Biol. 18: 4949;
- Hsp90 protein could potentially be useful in various diseases, other than the cancer mentioned above, such as parasitic, viral, fungal, or neurodegenerative diseases, by direct action on Hsp90 and special customers.
- diseases other than the cancer mentioned above, such as parasitic, viral, fungal, or neurodegenerative diseases, by direct action on Hsp90 and special customers.
- Some examples are presented below: vi) malaria: Plasmodium falciparum Hsp90 protein
- Toxoplasmosis Toxoplasma gondii, the parasite responsible for toxoplasmosis, has a chaperone protein Hsp90, for which induction has been shown during tachyzoite conversion. bradyzoite, corresponding to transition from chronic infection to active toxoplasmosis.
- geldanamycin blocks in vitro this tachyzoite-bradyzoite conversion (J.
- Hsp90 protein potentiates the evolution of drug resistance. , allowing new mutations to develop. Therefore, an Hsp90 inhibitor, alone or in combination with other antifungal therapy, may be useful in the treatment of some resistant strains (Science 309: 2185;
- Hepatitis B Hsp90 is one of the host proteins that interacts with hepatitis B virus reverse transcriptase during the replication cycle of the virus.
- Hsp90 The first known inhibitors of Hsp90 are compounds of the amsamycin family, in particular Geldanamycin (1) and Herbimycin A. X-ray studies have shown that Geldanamycin binds to the ATP site of the N-terminal domain. Hsp90 where it inhibits the ATPase activity of chaperone (Prodromou C. et al, CeII (1997), 90, 65-75)
- 17-AAG (2) an Hsp90 inhibitor derived from geldanamycin (1), which blocks the ATPase activity of Hsp0O by binding to the recognition site. N-terminal of the ATP.
- the results of Phase I clinical trials of 17-AAG (1) now lead to the initiation of phase II trials, but also direct research to more soluble derivatives such as Kosan BioSciences analogue 3 (17-DMAG). ), carrying a dimethylamine chain in place of the methoxy residue, and to optimized formulations of 17AAG (CNF1010 from Conforma Therapeutics):
- Radicicol (4) is also a naturally occurring Hsp90 inhibitor (Roe S.M. et al., J. Med Chem (1999), 42, 260-66). However, if it is by far the best in vitro inhibitor of Hsp90, its metabolic instability towards sulfur nucleophiles makes it difficult to use in vivo. Oxim derivatives much more stable such as KF 55823 (5) or KF 25706 were developed by Kyowa Hakko Kogyo (Soga et al, Cancer Research (1999), 59, 2931-2938)
- US2006089495 discloses mixed compounds comprising a quinone ring, such as amsamycin derivatives, and a resorcinol ring such as radicicol analogs, as Hsp90 inhibitors.
- novobiocin 10-10 binds to a different ATP site located in the C-terminal domain of the protein (Itoh H. et al, Biochem J. (1999), 343, 697- 703. Recently, simplified analogues of Novobiocine have been identified as more potent inhibitors of Hsp90 than Novobiocin itself (J. Amer Chem Soc (2005), 127 (37)).

- a depsipeptide named Pipalamycin or IC1101 has also been described as a noncompetitive inhibitor of the ATP site of Hsp90 (J. Pharmacol Exp Ther (2004), 310, 1288-1295).
- Sherperdine a KHSSGCAFL nonapeptide, mimics a portion of the Survivin sequence K79-K90 (KHSSGCAFLSVK) and blocks the interaction of the IAP family proteins with Hsp90 in vitro (WO2006014744).
- Small peptides including an Otoferline type sequence (YSLPGYMVKKLLGA), have recently been described as Hsp90 inhibitors (WO2005072766).
- Purines such as PU3 compounds (11) (Chiosis et al., Chem Biol. (2001), 8, 289-299) and PU24FCI (12) (Chiosis et al., Curr Cane Drug
