  • Patent number: 6008211
    Abstract: A broad class of photosensitive compounds having enhanced in vivo target tissue selectivity and versatility in photodynamic therapy. Many furocoumarin compounds, such as psoralens, exhibit cytostatic activity when photoactivated but exhibit little in vivo specificity for selectively accumulating in any particular target tissue such as atheromatous plaques. Reactive Oxygen Producing Photosensitizers ("ROPPs") are photoactivatable compounds having an affinity for hyperproliferating cells (such as atheromatous plaque cells), which when photoactivated, produce cytotoxic reaction products. The photoactivity of a ROPP, such as a porphyrin, may be reduced by metalating the porphyrin while the selective affinity of the metalized ROPP for hyperproliferating tissue remains substantially unchanged.

  • Patent number: 5886173
    Abstract: A method has been developed which utilizes a metal-2,4-dicarbonyl complex as an organic solvent soluble metal ion source in the metallation of polyazamacrocycles including porphyrins, expanded porphyrins and porphyrinoid compounds. Use of a metal ion source which is soluble in the metallation reaction medium produces significantly higher yields of a measurably purer product than is achieved using an insoluble or only sparingly soluble metal salt as in the prior art. Additionally, because the metallation can be performed in relatively concentrated mixtures, the reaction times are dramatically shorter and the amount of waste produced is less than when simple metal salts serve as the metal ion source. Further, use of the soluble metal-2,4-dicarbonyl complex simplifies the purification protocol required for the metallated expanded porphyrin.

  • Patent number: 5801229
    Abstract: Texaphyrins are provided for use as radiation sensitizers. Advantageous properties of texaphyrins for use as a radiation sensitizer include: i) a low redox potential which allows radiation-induced hydrated electrons to flow to texaphyrin rather than neutralizing hydroxyl radicals, allowing hydroxyl radicals to cause cellular damage, ii) a relatively stable texaphyrin radical that reacts readily to covalently modify neighboring molecules causing further cellular damage, iii) intrinsic biolocalization, and iv) indifference to the presence or absence of O.sub.2. These properties allow texaphyrins to be particularly effective for treating the hypoxic areas of solid neoplasms. Methods of treatment for an individual having a neoplasm or atheroma include the use of a texaphyrin as a radiation sensitizer and as an agent for photodynamic tumor therapy, or the use of a texaphyrin for internal and for external ionizing radiation. Novel texaphyrins are provided.

  • Patent number: 5789586
    Abstract: A method for preparing functionalized derivatives of organic or inorganic compounds and tetrapyrrolic compounds in particular, all of which compounds have at least one sulfonic acid group, by first preparing a sulfonyl halide intermediate of the compound then reacting the intermediate with a second compound having a reactive hydroxyl or amine group to yield the desired sulfonylamide or sulfonic esters thereof. The method may be used to produce a variety of photosensitive compounds having different functionality. For example, sulfonamide or sulfonic ester reaction products of the tetrapyrrolic compounds or other photosensitive organic molecules may exhibit an enhanced ability to localize at a particular target site for phototherapy.

  • Patent number: 5756726
    Abstract: Novel texaphyrin compounds having improved functionalization are described. Metal complexes of these compounds are active as photosensitizers for the generation of singlet oxygen and thus are potentially useful for treatments performed with singlet oxygen. Several of the metallotexaphyrin complexes absorb light in the physiologically important range of 690-880 nm. The complexes form long-lived triplet states and thus may act as efficient photosensitizers for generation of singlet oxygen.
