Definitions
- the invention concerns certain novel quinoline derivatives, or pharmaceutically- acceptable salts thereof, which possess anti-tumour activity and are accordingly useful in methods of treatment of the human or animal body.
- the invention also concerns processes for the manufacture of said quinoline derivatives, to pharmaceutical compositions containing them and to their use in therapeutic methods, for example in the manufacture of medicaments for use in the prevention or treatment of solid tumour disease in a warm-blooded animal such as man.
- Cancer is a disease in which cells grow and divide in an uncontrolled fashion. This uncontrolled growth arises from abnormalities in signal transduction pathways that are used by normal cells to regulate cell growth and division in response to various signalling molecules. Normal cells do not proliferate unless stimulated to do so by specific signal molecules located outside the cell derived from nearby cells or tissues.
- Growth factors bind to the cell membrane via specific receptors which have intrinsic enzyme activity. These receptors relay the growth signal to the cell nucleus via a series of signalling proteins.
- receptors In cancer, a number of defects in signal pathways are apparent. For example, cancer cells may produce their own growth factors which bind to their cognate receptors, resulting in an autocrine loop, or receptors may be mutated or overexpressed leading to an increased, continuous signal to proliferate. In addition, negative regulators of cell growth may be lost.
- Oncogenes are cancer related genes which often encode abnormal versions of signal pathway components, such as receptor tyrosine kinases, serine-threonine kinases, or downstream signaling molecules such as the ras genes, which code for closely related small guanine nucleotide binding proteins which hydrolyse bound guanosine triphosphate (GTP) to guanosine diphosphate (GDP). Ras proteins are active in promoting cell growth and transformation when they are bound to GTP and inactive when they are bound to GDP. Transforming mutants of p2 Iras are defective in their GTPase activity and hence remain in the active GTP bound state.
- signal pathway components such as receptor tyrosine kinases, serine-threonine kinases, or downstream signaling molecules such as the ras genes, which code for closely related small guanine nucleotide binding proteins which hydrolyse bound guanosine triphosphate (GTP) to guanosine diphosphat
- the ras oncogene is known to play an integral role in certain cancers, and has been found to contribute to the formation of over 20% of all cases of human cancer.
- cell surface receptors which are coupled to the mitogenic response, such as growth factor receptors, initiate a chain of reactions which leads to the activation of guanine nucleotide exchange activity on ras.
- guanine nucleotide exchange activity on ras.
- a number of proteins interact directly with ras at the plasma membrane resulting in signal transmission through several distinct pathways.
- the best characterised effector protein is the product of the raf proto-oncogene.
- the interaction of raf and ras is a key regulatory step in the control of cell proliferation.
- MEK1 and MEK2 are the immediate upstream activator of mitogen activated protein kinase (MAPKs known as extracellular signal regulated protein kinases or ERK1 and ERK2).
- MAPKs mitogen activated protein kinase
- ERK1 and ERK2 mitogen activated protein kinase
- MAPK mitogen activated protein kinase
- no substrates of MEK other than MAPK have been identified, though recent reports indicate that MEK may also be activated by other upstream signal proteins such as MEKK1 and Cot/Tpl-2.
- Activated MAPK translocates and accumulates in the nucleus, where it can phosphorylate and activate transcription factors such as Elk-1 and Sapla, leading to the enhanced expression of genes such as that for c-fos.
- the ras-dependent raf-MEK-MAPK cascade is one of the key signalling pathways responsible for transmitting and amplifying mitogenic signals from cell surface to the nucleus resulting in changes in gene expression and cell fate. This ubiquitous pathway appears essential for normal cell proliferation and constitutive activation of this pathway is sufficient to induce cellular transformation. Transforming mutants of ⁇ 21ras are constitutively active, resulting in raf, MEK and MAPK activity and cell transformation. Inhibition of MEK activity using either antisense raf, a dominant negative MEK mutant or the selective inhibitor PD098059 have been shown to block the growth and morphological transformation of ras-transformed fibroblasts.
- the mechanism of activation of raf, MEK and MAPK is through phosphorylation on specific serine, threonine or tyrosine residues.
- Activated raf and other kinases phosphorylate MEK1 on S218 and S222 and MEK2 on S222 and S226. This results in MEK activation and subsequent phosphorylation and activation of ERK1 on T190 and Y192 and ERK2 on T183 and Yl 85 by the dual specificity MEKs.
- MEK can be activated by a number of protein kinases, and active MAPKs phosphorylate and activate a number of substrate proteins including transcription factors and other protein kinases
- MEKs appear specific and sole activators of MAPKs and could act as a focal point for cross-cascade regulation.
- MEK1 and MEK2 isoforms show unusual specificity and also contain a proline-rich insert between catalytic subdomains IX and X which is not present in any of the other known MEK family members.

- Such combination products employ the compounds of this invention within the dosage range described hereinbefore and the other pharmaceutically-active agent within its approved dosage range.
- a pharmaceutical product comprising a quinoline derivative of the formula I as defined hereinbefore and an additional anti-tumour agent as defined hereinbefore for the conjoint treatment of cancer.
- the compounds of the Formula I are primarily of value as therapeutic agents for use in warm-blooded animals (including man), they are also useful whenever it is required to inhibit the effects of MEK enzymes. Thus, they are useful as pharmacological standards for use in the development of new biological tests and in the search for new pharmacological agents.
- melting points are uncorrected and were determined using a Mettler SP62 automatic melting point apparatus or an oil-bath apparatus; melting points for the end-products of the Formula I were determined after crystallisation from a conventional organic solvent such as ethanol, methanol, acetone, ether or hexane, alone or in admixture; (viii) the following abbreviations have been used:-
- 4-amino-l,3-benzoxazole was prepared as described in Katritzky, Alan R.; Musgrave, Richard P.; Rachwal, Bogumila; Zaklika, Chris, Heterocycles, 1995, 41(2), 345-52.
- the 4-chloro-6-methoxy-7-[3-(4-methylpiperazin-l-yl)propoxy]quinoline-3-carbonitrile used as starting material was prepared as follows:
- the 7-nitrobenzoxazole used as starting material was prepared as follows:- 2-Hydroxy-3-nitroaniline (1.24g, 8.05mmol), trimethylorthoformate (1.2ml, ll.Ommol) and _- toluenesulfonic acid (50mg) were heated at 100° for lhr. then a further l.Oml trimethylorthoformate added and heating continued for a further lhr. The resulting mixture was purified by column chromatography on silica using iso-hexane:ethyl acetate (3:2) as eluent.
- the 4-[(2-amino-3-hydroxyphenyl)amino]-3-cyano-6,7-dimethoxyquinoline used as starting material was prepared as follows:- 2-Amino-3-nitrophenol (2.0g, 13.0mmol), di-tert-butyldicarbonate (3.1g, 14.2mmol) and 4- dimethylaminopyridine (50mg) in THF (15ml) were stirred at room temperature for 3hr.
- Trifluoroacetic acid (10ml) was added in one go, at room temperature, to a stirred mixture of tert-butyl ⁇ 2-[(3-cyano-6,7-dimethoxyquinolin-4-yl)amino]-6-hydroxyphenyl ⁇ carbamate (l.Og, 2.29mmol) and water (1.0ml). The resulting yellow solution was stirred for 30min then evaporated in vacuo. The residue was treated with saturated aqueous sodium bicarbonate solution to give 4-[(2-amino-3-hydroxyphenyl)amino]-3-cyano-6,7-dimethoxyquinoline (725mg, 94%) as a pale yellow solid; Mass Spectrum: M+H + 337.
- Example 4 4-(l,3-benzoxazol-7-ylamino)-6,7-dimethoxyquinoline-3-carbonitrile 4-chloro-3-cyano-6,7-dimethoxyquinoline (300mg, 1.21mmol) and 7-amino-l,3-benzoxazole (178mg, 1.33mmol) in DMF (4ml) were cooled in an ice-water bath then treated dropwise, under an atmosphere of nitrogen, with sodium hexamethyldisilazide (1.0M in THE, 2.5ml). The resulting solution was stirred at ice temperature for a further 1 hr. before quenching in dilute aqueous ammonium chloride and extracting with dichloromethane.
- the 7-amino-l,3-benzoxazole used as starting material was prepared as follows:- 2-Amino-6-nitrophenol (1.24g, 8.05mmol) and para toluenesulfonic acid (50mg) in trimethyl orthoformate (2ml) were tirred and heated at 100° for 2hr. The resulting solution was cooled to room temperature then purified by column chromatography on silica using 40% ethyl acetate in iso-hexane as eluent.
- Maize starch paste (5% w/v paste) 2.25
- the above formulation may be obtained by conventional procedures well known in the pharmaceutical art.
- the tablet may be enteric coated by conventional means, for example to provide a coating of cellulose acetate phthalate.
