Definitions
- the present invention relates to novel thymine derivatives and their use as drugs for the selective inhibition of the heat shock protein HSP27 (HSPB1).
- HSP27 heat shock protein
- Some types of cancer are known to be poorly responsive to treatment with cytotoxic drugs from the outset. But even in patients with actually treatable cancers, the therapy may fail after some time. One possible reason is resistance, which makes the tumor cells insensitive to cytostatics. Some underlying biological processes are known.
- heat shock proteins are evolutionarily highly conserved proteins, which are formed by the cell under sublethal stress conditions. Heat shock proteins are chaperones whose natural task is to restore proteins that have been denatured by heat or chemicals to their proper state or to prevent the denaturation of proteins. Due to their mode of operation, heat shock proteins are overexpressed in a variety of cancer cells. In recent years, therefore, heat shock proteins have emerged as promising targets for cancer therapy.
- HSP27 The heat shock protein HSP27 (HSPB1) is involved in a variety of cellular processes, such as apoptosis (programmed cell death), DNA repair and recombination. HSP27 is overexpressed in the cell in a wide range of cancers, including prostate cancer, colorectal cancer, liver and breast cancer, and influences the course of the disease. It was found that an increased expression of HSP27 with an increased resistance to cytostatics, such as gemcitabine (2 ', 2'-Difluordesoxycytidin) or bortezomib (Ve- Icade), accompanied by chemotherapy. Due to the negative influence of HSP27 on chemotherapy, HSP27 is considered a promising additional target for cancer therapy, especially for the suppression of chemoresistance.
- cytostatics such as gemcitabine (2 ', 2'-Difluordesoxycytidin) or bortezomib (Ve- Icade
- JP 2010 215669 A or US 2012/294846 A1 is based on the suppression of gene expression of HSP27 by the direct intervention in the translation or transcription by means of intracellular application of antisense oligonucleotides or double-stranded small interfering (si) RNA. Tie it the nucleotide-based inhibitors to the DNA or RNA and thereby specifically prevent the formation of HSP27 in the cell.
- WO 2013 114339 A1 discloses a combination therapy for the treatment of cancer on the basis of the synergetic effect of a nucleotide inhibitor for inhibiting the expression of HSP27 in conjunction with an inhibitor against the protein EGFR (epidermal growth factor receptor), such as erlotinib, or antifolates like pemetrexed.
- the nucleotide inhibitor is preferably an antisense oligonucleotide or a double-stranded siRNA.
- nucleotide-based inhibitors are their excess of negative charges and the associated high polarity of the drug molecules, whereby the bioavailability is considerably minimized. Even more problematic is the enormous chemical instability of nucleotide-based inhibitors, in particular of RNA-based inhibitors.
- short nucleotide-based inhibitors have the disadvantage of being potentially immunogenic, whereby they also act, for example, by secretion on non-transfected cells (eg macrophages), thereby inducing a strong and harmful to the patient immune response in the organism.
- nucleotide-based inhibitors are low molecular weight, organic compounds, since these usually have a high stability in a biological system and at the same time a good bioavailability. Especially in the case of highly specific compounds, the "off-target effects" typical of other methods (for example due to the otherwise necessary transfection) do not occur.
- DE 10 2008 035 299 A1 describes a method herein, after which the low molecular weight organic compound (E) -5- (2-Bromovinyl) -2 '-Deoxyuridine (BVDU) interacts directly with the protein HSP27 and thereby inhibits the function of the HSP27.
- BVDU as a weak HSP27 inhibitor thus increases the sensitivity to cytostatic-induced apoptosis so that pancreatic cancer patients receive a survival advantage by oral administration of BVDU.
- Clinical studies in late-stage pancreatic cancer patients have shown that BVDU is safe and effective at a dose of 500 mg / day. However, BVDU with an administered elevated dose of 760 mg / day was found to be detrimental to lightweight patients.
- the above-described compound BVDU and its derivatives in DE 10 2008 035 299 A1 are the only known low molecular weight inhibitors of HSP27.
- the active ingredients present have a considerable potential for improvement in terms of binding affinity.
- WO 2009/156182 A2 describes uracil derivatives of the general formula I.
- the object of the present invention is therefore to provide chemical compounds which inhibit the heat shock protein HSP27 as selectively and potently as possible, in particular for use in cancer therapy.

- purine derivatives according to the general formula (I) or (II) and thymine derivatives of the formula (VI), (VI '), (VII) or (VIII) inhibit the HSP27 protein by a specific interaction with the Drug binding pocket of the HSP27 protein.
- the advantage of the purine derivatives according to the general formula (I) or (II) and the thymine derivatives according to the general formula (VI), (VI '), (VII) or (VIII) for use in cancer therapy is that these compounds have at least 50-fold higher activity for the selective inhibition of HSP27 than currently known compounds.

- cancer-causing binding partners for example proteins
- Caspases are the most important enzymes of apoptosis in animals (programmed cell death).
- the present invention is based on the recent finding that HSP27, which is overexpressed in many cancers and adversely affects the course of the disease, has a drug binding pocket for low molecular weight, organic compounds, which binds to the functionality (eg binding to client proteins and probably also the oligomerization) of the HSP27 protein and its activity is central.
- the functionality of the drug binding pocket is based on two phenylalanine residues at positions 29 and 33 (Phe29 and Phe33) in the amino acid sequence of the protein.
- the drug binding pocket of the HSP27 protein is a localized region (local tertiary structure) formed by the spatial arrangement of the amino acid sequence and having phenylalanine residues Phe29 and Phe33 (relative to the primary structure of HSP27).

- a client protein is a substrate, preferably a protein, on which HSP27 acts as a chaperone.
- the binding affinity is a measure of the binding strength between binding partners (here the low molecular weight, organic compound) and a target protein.

- organic compounds can be pre-determined via a virtual screening, which interact much more specifically with the drug binding pocket of HSP27 than known compounds.
- virtual screening encompasses a drug discovery process known to those skilled in the art in which new drug molecules are to be found by in silico methods (i.e., in computer experiments).
- the binding affinity (Kj) of these potential inhibitors is not measured by wet-chemical experiments, as in a classical screening, but predicted by computer-based methods.
- the structure of the HSP27 protein may undergo changes. Often these changes are limited to side-chain conformation, but whole groups of amino acids can move with their peptide backbone.
- a few low molecular weight organic compounds must subsequently be experimentally probed by in vitro (ie, outside a living organism), in situ (ie, in cells, preferably in cell cultures), and / or in vivo (ie, in the living organism) be tested for their physicochemical affinity for the drug binding pocket of HSP27, which increases the efficiency for the detection of specific HSP27 inhibitors while reducing costs.
- Such in vitro tests for determining the affinity towards the drug binding pocket of HSP27 are carried out, for example, via binding assays in which the association of two unlabelled binding partners are measured (eg, bio-layer interferometry).
- the function of the target protein or its inhibition can also be quantified in aggregation assays.
- the purine derivatives according to the invention of the general formula (I) or (II) and thymine derivatives of the formula (VI), (VI '), (VII) or (VIII) compared to HSP27 protein have a dissociation constant (K D ) in the range of 10 nM / L to 1000 ⁇ / L, preferably in the range of 100 nM / L to 800 ⁇ / L have.

- Low molecular weight organic compounds have the significant advantage over large molecules (e.g., nucleotide-based inhibitors such as antisense oligonucleotides or RNA oligonucleotides) of having much better handleability and stability under physiological conditions. Furthermore, low molecular weight, organic Compounds usually cell-like and therefore easier to apply in the cell or an organism.

- the separation method is that larger molecules, such as proteins, form a matrix of Sephadex G-25 happen while low-molecular-weight compounds (small molecules) penetrate into the matrix and do not pass through it.
- PD SpinTraps G-25 from GE Healthcare was used. These columns allow molecules of molecular weight greater than or equal to 5000 g / mole to pass through the 2-minute centrifugation at 800 xg (as directed), while retaining smaller molecules in the matrix.
- the target protein HSP27 has a molecular weight of 27000 g / mol and thus passes through the matrix.

- Bio-Layer Interferometry is a technique for detecting biomolecular interactions. It is an analytical technique that measures the optical interference of white light reflected from two surfaces: a surface consists of a layer of the immobilized target protein on the tip of the biosensor and an internal reference surface. The binding of ligands to the target protein alters the interference pattern and can be measured in real time. A ForteBio Octet Red 384 instrument was used for the measurements. The target protein HSP27 was biotinylated and bound to the corresponding sensors (SSA). A big advantage of this analysis method is that the analytes do not have to be immobilized or labeled. The purine derivatives of the general formula (I) or (II) pre-determined by means of in silico screening are used for these measurements in a concentration range (K D ) between 333 / mol / L and 10 nmol / L.

The aggregation is measured in the spectrometer at 500 nm (light scattering by protein aggregates). The presence of HSP27 (HSP) counteracts aggregation (see Graph, CS + HSP). Since the addition of the test substances (BVDU and 2- (3-trichlorovinyl-phenylamino) -1, 9-dihydro-purine 6-on) inhibit the chaperone function of HSP27, the activity of the respective test substance can be determined by measuring the aggregation behavior of the CS.
- HSP27 HSP27
- the inhibition of HSP27 correlates with the binding strength of a low molecular weight organic compound to the drug binding pocket of HSP27.

- the CCD-186Sk cystic fibrosis cell line (ATCC® CRL-1563 TM) was used.
- the cystic fibrosis cell line CCD-186Sk homozygous carries the AF508 mutation affecting the CFTR gene.
- the deletion of phenylalanine at position 508 of the CFTR gene is typical of this disease and affects over 70% of patients. Because of this deletion, the resulting CFTR protein is not completely correctly folded and for this reason fed to the cellular degradation processes and not transported - as the healthy protein - to the cell membrane and incorporated there as a transmembrane protein.
- HSP27 plays a crucial role in the secretion of the Delta F508 CFTR protein towards degradation.
- the experiments serve to demonstrate the hypothesis that Delta F508-CFTR protein, which is not secreted and degraded directly during production, is transported to the cell membrane where it regulates water and salt transport through the plasma membrane of the cells as a functioning transmembrane protein.
- the CCD-186Sk cells are seeded for this purpose at a density of 100,000 cells / ml and with:
- CFTR protein incubated as representatives of the purine derivatives in the respective concentration. Cells are harvested every 24 hours and it is checked if the treated cells present more CFTR on the cell surface than untreated cells.
- an antibody is used that specifically labels the extracellular "loop" (amino acids 103-117) of the CFTR protein, which is labeled with the fluorescent dye FITC and detected by flow cytometry.
- biotinylated HSP27 protein was first bound to super streptavidin sensors (SSA, Fortebio). Subsequently, the loaded sensors were incubated with Biocytin ("quenched"). For reference, uncharged SSA sensors were incubated with biocytin, and in the case of specific binding of the analyte to HSP27, the loaded HSP27 sensor produces a stronger signal than the response tracking reference sensor

For the treatment with 30 ⁇ / L BVDU, a final cell count of 290,000 cells / ml was detected, whereas the final cell count on culture without addition of an HSP27 inhibitor amounts to 950,000 cells / ml. As a control, RPMI 8226 cells were treated with the respective test substances alone, FIG. 6b. At the same dosage, the test substances alone do not affect cell growth.
- Example 14 Inhibition of resistance formation of the tumor cell line RPMI-8226 by 2- (3-trichlorovinyl-phenylamino) -1,9-dihydro-purin-6-ones
- FIG. 7a shows that resistance to the cytostatic bortezomib was significantly inhibited by treatment with 1 ⁇ mol / 2 2- (3-trichlorovinyl-phenylamino) -1,9-dihydro-purin-6-one.
- 270,000 live cells per ml of medium were detectable.
- BVDU was detected to have a final cell count of 290,000 cells / ml, whereas the final cell count on culture without the addition of an HSP27 inhibitor was 950,000 cells / ml.
- Figure 7b At the same dosage, the test substances alone do not affect cell growth.
- Example 15 Inhibition of the resistance formation of the tumor cell line RPMI-8226 by 9H-xanthene-9-carboxylic acid [4- (5-methyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-yl) -but- 2-enyl] -amide
- FIG. 8a shows that treatment with 1 ⁇ mol / L 9H-xanthene-9-carboxylic acid [4- (5-methyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-yl) -but -2-enyl] -amide resistance to the cytostatic bortezomib was significantly inhibited.
- 290,000 live cells per ml of medium were detectable.
- FIG. 9a shows that treatment with 1 ⁇ / L 2-biphenyl-4- yl-N- [4- (5-methyl-2,4-dioxo-3-dihydro-2H-pyrimidin-1-yl) -but-2-enyl] -acetam resistance to the cytostatic bortezomib was significantly inhibited. At the end of the experiment, 380,000 live cells per ml of medium were detectable.
- the cell line U-937 is a histiocytic lymphoma (DSMZ ACC 5). This cell line also responds to treatment with bortezomib, expresses HSP27 and develops resistance to bortezomib. Bortezomib is not the standard therapy for this lymphoma but is discussed as a potential therapeutic.
- FIG. 10a shows that resistance to the cytostatic bortezomib was significantly inhibited by the treatment with 0.75 ⁇ mol / L accepromazine. At the end of the experiment, 70,000 live cells per ml of medium were detectable. For the treatment with 30 ⁇ / L BVDU, a final cell count of 250,000 cells / ml was detected, whereas the final cell count during cultivation without the addition of an HSP27 inhibitor amounts to 450,000 cells / ml. For control U-937 cells were treated with the respective test substances alone, Figure 10b. At the same dosage, the test substances alone do not affect cell growth.
