Patent number: 6008211Abstract: 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.Type: GrantFiled: July 27, 1995Date of Patent: December 28, 1999Assignee: PDT Pharmaceuticals, Inc.Inventors: Byron Robinson, Alan R.

Patent number: 5886173Abstract: 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.Type: GrantFiled: July 30, 1997Date of Patent: March 23, 1999Assignee: Pharmacyclics, Inc.Inventors: Gregory W.

Patent number: 5801229Abstract: 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.

Patent number: 5756726Abstract: 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.Type: GrantFiled: June 6, 1995Date of Patent: May 26, 1998Assignees: Pharmacyclics, Inc., Board of Regents, The University of Texas SystemInventors: Gregory W. Hemmi, Jonathan L. Sessler, Tarak D. Mody
