bThe present invention relates to novel compounds, particularly to compounds

The present invention relates to novel compounds, particularly to compounds comprising a photoactive unit, said novel compounds being particularly suitable for ophthalmic devices as well as to ophthalmic devices comprising such compounds.

Background and description of the prior art

Cataract is a general term of an affection of the eye that leads to a loss of vision and in the extreme to blindness by clouding of the normally clear lens of the eye. It is the major cause of blindness in the world with it affecting more than 100 million people. Due to the fact that its major cause is age, it is expected that with the population's average age continuing to increase the number of cataracts will continue to increase substantially in the future.

Effective treatment of cataract is only possible by surgical intervention, whereby the natural lens of the eye is removed through an incision in the cornea and replaced with an artificial lens, often also referred to as "intraocular lens". In preparation of surgery current state-of-the-art surgical methods employ methods for eye mapping so as to approximate the refractive power best suited to the respective patient.

Even though cataract surgery is one of the most widely used and safest surgical procedures it is not without specific post-surgery problems. It frequently happens that the refractive power of the implanted intraocular lens (IOL) is insufficient for restoring good vision. Such problems may, for example, be caused by changes in eye geometry in consequence of the surgery as well as irregular wound healing and positioning errors that result in the artificial lens not having the optimal optical properties. As a result the patient will still require corrective vision aids, e.g. glasses, to be able to see correctly. In some cases the resulting refractive power of the implanted artificial lens is so far removed from the required refractive power that further surgery will be required. Particularly for aged persons this is not desirable because the body's capability for healing are reduced with increasing age. Furthermore, there is the risk of attracting endophthalmitis, an inflammation of the eye, which can even lead to a complete loss of vision or worse, loss of the eye.

There is therefore a need in the health sector for optically active devices, and particularly artificial intraocular lenses, that would allow for non-invasive adjustment of refractive power after implantation of the lens, thereby preferably further reducing the need for post-surgery vision aids.

Some developments in this sense have already been made, as for example evidenced by WO 2007/033831 Al. However, the compounds disclosed therein suffer from being too stiff and too brittle so that they can't be rolled or folded and are thus not fit to be implanted by state of the art cataract surgical methods, particularly by state of the art micro- incision cataract surgical methods. Consequently, it is an objective of the present application to provide for novel compounds suitable for ophthalmic devices.

It is also an objective of the present application to provide for compounds, the optical properties of which may be changed, preferably by non-invasive techniques.

It is a further objective of the present application to provide for novel compounds that are more flexible than the currently known compounds, preferably in combination with being suitable for ophthalmic devices.

Further advantages and objectives of the compounds of the present application will be evident to the skilled person from the following detailed description as well as from the examples. Summary of the invention

Beginning with (E)-cinnamic acid, the acid was converted to the corresponding cinnamoyi chloride under standard conditions. Then, the acid chloride compound was treated with the aniline derivative to obtain the amide compound. The final step was an iodine mediated ring-closure reaction, which contains a rearrangement step. This reaction is known to the chemical expert and prior art from the literature (Org.

On the one hand side, the aniline-derivate could be equipped with a para-hydroxy group. As the second opportunity, the cinnamic acid derivative could be also functionalized with a para-hydroxy group. To then obtain the final monomer, the lactame derivative was alkylated with an aliphatic bromo-alcohol-derivative. This compound was then finally treated with the corresponding acrylate-derivative.

It is, however, preferred that the present oligomers and polymers are made by radical polymerization, wherein the polymerization reaction is started by means of a suitable radical polymerization initiator. For the purposes of the present application the type of radical polymerization initiator is not particularly limited and may be any suitable radical generating compound. Such compounds are well known to the skilled person. Suitable polymerization initiators may be selected from thermal initiators or photo initiators, i.e. compounds that generate radicals by exposure to heat or irradiation with light of a suitable wavelength.

Suitable crosslinkers may be used to impart elastomeric properties to the present composition and the articles produced therewith. Typically any suitable di- or tri- functional monomer may be used as crosslinker. Such monomers are generally well known to the skilled person. The present compound of formula (I) is particularly well suited for use in optically active devices. Hence the present application also provides for optically active devices comprising the compound of formula (I). Preferred optically active devices are ophthalmic devices. Examples of such ophthalmic devices include lenses, keratoprostheses, and cornea inlays or rings. More preferably, said optically active device is a lens. Most preferably, such optically active device is an intraocular lens, which may, for example, be a posterior chamber intraocular lens or an anterior chamber intraocular lens.

The present optically active devices may be formed by a process comprising the steps of

Intraocular lenses in accordance with the present application are believed to show particularly advantageous properties in that they are flexible enough so as to be rolled or folded and consequently requiring a much smaller incision for them to be inserted into the eye. It is believed that this will allow for improved healing of the eye, particularly in respect to the time for the eye to heal.

The type of intraocular lens is not limited in any way. It may, for example, comprise one or more optic and one or more haptic components, wherein the one or more optic components serve as lens and the one or more haptic components are attached to the one or more optic components and hold the one or more optic components in place in the eye. The present intraocular lens may be of a one-piece design or of multi-piece design, depending on whether the one or more optic components and the one or more haptic components are formed from a single piece of material (one-piece design) or are made separately and then combined (multi-piece design). The present intraocular lens is also designed in such a way that it allows to be, for example, rolled up or folded small enough so that it fits through an incision in the eye, said incision being as small as possible, for example, at most 3 mm in length..

Additionally, intraocular lenses in accordance with the present application allow for the non-invasive adjustment of the optical properties, particularly the refractive power, after implantation of the lens into the eye, thus reducing the need for post-surgery vision aids or reducing or totally avoiding follow-up surgery. ln order to change the optical properties and particularly the refractive power of the intraocular lens it is exposed to irradiation having a wavelength of at least 200 nm and of at most 1500 nm. Hence, the present application also provides for a process of changing the optical properties of an optically active article as defined herein, said process comprising the steps of

a) providing an article as defined herein; and

b) subsequently exposing said article to irradiation having a wavelength of at least 200 nm and at most 1500 nm.

Example 7 - General procedure for the solvent polymerization of the monomers

The corresponding monomer was dissolved in dry N,N-dimethylformamid (65.0 equiv.) in a Schlenck-tube with a stirring bar. The solution was degassed performing three times freeze-evacuate-thaw cycles. After that, azoisobutyronitrile (AIBN, 0.05 equiv.) was added in one portion to the degassed solution, which was heated up to 65 °C in an oil bath for a minimum of three days. The solution was cooled to room temperature and was then poured dropwise into cold methanol (100 ml methanol / 100 mg monomer) while stirring. The precipitated polymer was collected on a frit or the solution was centrifuged several times to obtain the final polymer material.

Thus, polymers (P-1) to (P-47) can be synthesized from the respective monomers (M-l) to (M-47).
