Synthesis and photocleavage of a new polymerizable [2+2] hetero dimer for phototriggered drug delivery

7-Hydroxy-1,1-dimethylnaphtalenone is introduced as a versatile photocleavable linker system for drug attachment to polymer materials with significantly improved two-photon-absorption efficiency. The synthesis of TBDMS-protected 7-hydroxy-1,1-dimethylnaphtalenone monomer is described, which is the release group attached to the polymer moiety. The cytotoxic 5-fluoro-1-heptanoyluracil was photochemically attached via [2+2] cycloaddition to this release group. The linker-drug conjugate was photochemically polymerized into a HEMA/MMA copolymer. Photo-triggered drug release from the polymer via single-photon-absorption as well as two-photon-absorption in solution were carried out. The detachment of 5-FU from the polymer and its release from the polymer were monitored in the polymer as well as in the aqueous medium and multidose drug release was successfully demonstrated.

Thermal [2 + 2] cycloreversion of a cyclobutane moiety via a biradical reaction

The nature of the Woodward-Hoffmann-forbidden, thermal activated cycloreversion mechanism of cyclobutane has long been the subject of speculation and intense research. We were now able to prove the theoretically postulated biradicalic mechanism directly from radical scavenging reactions and electron paramagnetic resonance (EPR) experiments on [2 + 2] heterodimers of 5-fluoro-1-heptanoyluracil and 7-methoxy-1,1-dimethylnaphthalenon. The dimers show both the "allowed" photochemically as well as the "forbidden" thermally triggered [2 + 2] cycloreversion of the cyclobutane ring. The quantum efficiency of the photochemical cleavage is about 1%. The thermal cycloreversion reaction is independent from solvent and occurs at low activation energies of about 13 kcal/mol, even in the solid state. The radical scavenger and EPR results are further supported by the finding, that the reaction products are solely the educts for the anti-head-to-tail heterodimer. But for the syn-head-to-head heterodimer two additional products are observed, which require a sufficiently stable biradical intermediate to facilitate the required intramolecular rearrangements. Because of the surprisingly high lifetime of the radical species of these heterodimers it was possible to prove the long-discussed biradical mechanism experimentally.

1,1-Dimethylnaphthalenon-dimers as photocleavable linkers with improved two-photon-absorption efficiency and hydrolytic stability

Coumarins are well known for reversible dimer formation with wavelengths greater than 300. nm and dimer cleavage below 300. nm. In a photochemical [2+2]-cycloaddition a cyclobutane ring is formed. Formation as well as cleavage of the cyclobutane ring may be accomplished by a single-photon-absorption as well as by a two-photon-absorption triggered reaction. The coumarin system is of interest for various kinds of applications, ranging from drug delivery for ophthalmic implants to optical data storage. However, the two-photon-absorption coefficient of coumarin dimers is rather low falling in the range of 1. GM in the visible range. We present here a substitute for the coumarin dimer system which not only has an about one order of magnitude higher two-photon-absorption coefficient, but also overcomes several other problems of the coumarin dimer system. Coumarines and in particular coumarine dimers have a very limited solubility in common solvents and are susceptible to hydrolysis of the lactone ring, which leads to an undesired complexity in the photochemical cleavage reaction. The 1,1-dimethylnaphtalenone dimers introduced here show excellent stability, lead only to a single cleavage product, and have a two-photon-absorption coefficient of about 10. GM at 532. nm. These properties make the 1,1-dimethylnaphtalenone dimers a superior substitute over the well-known coumarin dimers in particular in applications where two-photon-absorption induced photocleavage is required.
