Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: Invention Title: New quaternary ammonium compounds, a process for the preparation thereof and the pharmaceutical use thereof The following statement is a full description of this invention, including the best method of performing it known to me us: -1- NEW QUATERNARY AMMONIUM COMPOUNDS, A PROCESS FOR THE PREPARATION THEREOF AND THE PHARMACEUTICAL USE THEREOF The present invention relates to new quaternary ammonium compounds, to a process for their preparation and to pharmaceutical compositions containing them.
The new quaternary ammonium compounds enable the vectorisation of active ingredients in cartilaginous tissue and hence the treatment of pathologies caused by attack on the cartilage whether they are articular or cancerous pathologies. They may also be used as diagnostic reagents, capable, for example, of revealing a pathology of the cartilage or a metabolism (radioactive marker, stained marker,...).
The therapeutic agents currently available commercially for the treatment of articular pathologies, such as arthritis or osteoarthritis, generally exhibit a low affinity for the target tissues and require the administration of high doses to achieve the desired therapeutic effect.
The administration of such strong doses of active ingredients gives rise to an increase in the frequency of side effects. For example, the administration of non-steroidal antiinflammatories is known to cause significant digestive toxicity.
In the field of bone cancerology, the therapeutic agents currently used for the treatment of chondrosarcomas are likewise known, for example, to produce undesirable side effects, especially toxicities, for example haematological or non-haematological toxicities.
Finally, in the field of diagnostic products for cartilaginous pathologies, the products currently used have the disadvantage of lacking specificity for the targets at which they are aimed.
There has thus been particular interest in functionalising those different kinds of compound in order specifically to target cartilaginous tissue and thus limit, or even suppress, the -2undesirable effects observed when such compounds are administered directly.
The new compounds forming the subject of the present invention make it possible, both by increasing the tropism and by decreasing the doses administered, for the side effects to be significantly attenuated and for the therapeutic index of the active molecules to be strengthened.
The present invention relates more specifically to compounds of a formula corresponding to formula (Ia) or (Ib):

PHARMACOLOGICAL STUDY OF THE COMPOUNDS OF THE INVENTION Pharmacokinetic study tissue distribution study This study was carried out with molecules labelled with '14C. The tissue distribution study was carried out by direct measurement of the radioactivity across whole-body sections in accordance with the following method male Sprague-Dawley rats were administered intravenously or orally with a dose of the labelled molecule. Then, at times ranging from minutes to 24 hours after the administration, the animals were sacrificed by ether inhalation and frozen in liquid nitrogen.
Sections were then prepared using a cryomicrotome and, after desiccation, the distribution of radioactivity was measured using an image analyser.
The results obtained with the compounds of the invention demonstrate that the compounds exhibit an increased tropism for cartilaginous tissues.
In respect of the compounds of Examples 4 and 5, apart from the kidney, an elimination organ which binds significant amounts of radioactivity in the first minutes following the injection, cartilage, and to a lesser degree skin, are the only targets. When the same study is carried out with non-functionalised glucosamine, the liver is the main target organ.
In respect of the compound of Example 6, cartilage exhibits a far greater affinity than the surrounding tissues. Maximum binding is achieved 5 minutes after injection. A very high 19 affinity for cartilage is likewise observed when this study is performed after administration of the labelled molecule by the oral route.
As for the compound of Example 8, that compound has a raised concentration in cartilaginous tissue 10 minutes after injection.
Comprises/comprising and grammatical variations thereof when used in this specification are to be taken to specify the presence of stated features, integers, steps or components or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
