Definitions
- Cyclin-dependent kinases are serine/threonine protein kinases and have key roles in the regulation of the cell cycle. They regulate the cell division cycle, apoptosis, transcription, differentiation and functions within the central nervous system. Aberrant activity of cdks is frequently implicated in cancer. Inhibitors of cdks have their use in the treatment of diseases such as cancer, alopecia, neurodegenerative disorders, viral infections and fungal infections (Knockaert etal. Trends Pharmacol. Sci.2002, 23, 417-425).
- Cyclin-dependent kinase 2 plays a crucial role in the transition through S phase and is one of the key components of the G1 checkpoint. Checkpoints serve to maintain the proper sequence of cell cycle events and allow the cell to respond to insults or proliferative signals. Loss of proper checkpoint control in cancer cells contributes to tumourigenesis.
- Inhibitors of cyclin-dependent kinases such as flavopiridol (a potent inhibitor of cdkl , cdk2 and cdk4), are currently in clinical trials.
- US-A-2002/0137778 and US-A-2002/0165259 describe aminothiazole compounds which are inhibitors of cyclin-dependent kinases.
- Sila-substitution (C/Si-exchange) of drugs is a relatively recent approach for searching for organo-silicon compounds which have beneficial biological properties. The approach involves the replacement of specific carbon atoms in compounds by silicon, and monitoring how the biological properties of the compounds have changed. A review of this approach is provided in Tacke and Zilch, Endeavour, New Series, 10, 191-197 (1986).

- excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinyl pyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long-chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids, for example polyoxyethylene sorbitan monooleate.
- dispersing or wetting agents may be a naturally occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long-chain aliphatic alcohols, for example heptadecaethyleneoxycetanol,
- the aqueous suspensions may also contain one or more preservatives, for example ethyl or n-propyl p- hydroxybenzoate, one or more colouring agents, one or more flavouring agents, and one or more sweetening agents, such as sucrose or saccharin.
- Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin.
- the oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents, such as those set forth above, and flavouring agents may be added to provide a palatable oral preparation.
- compositions may be preserved by the addition of an antioxidant such as ascorbic acid.
- Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable sweetening, flavouring and colouring agents may also be present.
- the pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions.
- the oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin, or mixtures of these.
- Suitable emulsifying agents may be naturally occurring gums, for example gum acacia or gum tragacanth, naturally occurring phosphatides, for example soya bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate.
- the emulsions may also contain sweetening and flavouring agents. Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose.
- Such formulations may also contain a demulcent, a preservative and flavouring and colouring agents.
- the pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above.
- the sterile injectable preparation may also be in a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1 ,3- butanediol.
- the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution.
- sterile, fixed oils are conventionally employed as a solvent or suspending medium.
- any bland fixed oil may be employed including synthetic mono- or diglycerides.
- fatty acids such as oleic acid, find use in the preparation of injectables.
- the compounds of the invention may also be administered in the form of suppositories for rectal administration of the drug.
- These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols.
- Compositions for topical administration are also suitable for use in the invention.
- the pharmaceutically active compound may be dispersed in a pharmaceutically acceptable cream, ointment or gel.
- a suitable cream may be prepared by incorporating the active compound in a topical vehicle such as light liquid paraffin, dispersed in a aqueous medium using surfactants.
- An ointment may be prepared by mixing the active compound with a topical vehicle such as a mineral oil or wax.
- a gel may be prepared by mixing the active compound with a topical vehicle comprising a gelling agent.
- Topically administrable compositions may also comprise a matrix in which the pharmaceutically active compounds of the present invention are dispersed so that the compounds are held in contact with the skin in order to administer the compounds transdermally.
