    • 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. By linking a furocoumarin compound to a ROPP to form a F-ROPP, the cytostatic properties of the furocoumarin portion of the F-ROPP can be exploited while the selective affinity of the ROPP portion of the compound for hyperproliferating cells such as atheromatous plaque provides enhanced tissue selectivity without cytotoxicity. In vivo, certain F-ROPPs may be forced to selectively accumulate in a target tissue by illuminating only the target tissue with light having a wavelength operable for photoactivating the F portion of the F-ROPP thereby causing the F-ROPP to either form a monoadduct with or crosslink the cellular DNA in the target tissue. Light of a second wavelength can then be delivered to the target tissue to photoactivate the ROPP portion causing further interference with cellular activity.
    • 广泛的光敏化合物具有增强的体内靶组织选择性和光动力疗法的多功能性。 许多呋喃香豆素化合物,如补骨脂素,当光活化时表现出细胞抑制活性,但是在任何特定靶组织如动脉粥样硬化斑块中选择性积累,但体内特异性较小。 活性氧生产光敏剂(“ROPP”)是具有对过度增殖细胞(如动脉粥样硬化斑块细胞)的亲和力的光活化化合物,其在光活化时产生细胞毒性反应产物。 可以通过金属化卟啉来减少ROPP如卟啉的光活性,同时金属化ROPP对过度增殖组织的选择性亲和性基本上保持不变。 通过将呋喃香豆素化合物与ROPP连接以形成F-ROPP,可以利用F-ROPP的呋喃香豆素部分的细胞生长抑制性能,而化合物的ROPP部分对过度增殖细胞如动脉粥样硬化斑块的选择性亲和力提高 组织选择性没有细胞毒性。 在体内,某些F-ROPP可能被迫通过用具有可激活F-ROPP的F部分的光波长的光照射目标组织而选择性地累积在靶组织中,从而使F-ROPP形成单加合物 与目标组织中的细胞DNA交联或交联。 然后可以将第二波长的光递送到目标组织以激活ROPP部分,导致进一步干扰细胞活性。

    • Porphyrazine compounds having moieties substituted at the eight peripheral .beta.-pyrrole positions are disclosed. The porphyrazine compounds have the general structural formula: ##STR1## wherein M is H.sub.2 or a metal capable of complexing with the pyrrole nitrogen atoms, and A, B, C and D are independently selected from the group consisting of a thio moiety, an amino moiety, an oxo moiety, a phospho moiety, a seleno moiety, a telluro moiety and a non-coordinating moiety, like a hydrocarbon moiety, with the proviso that not all of A, B, C and D are a thio moiety and that not all of A, B, C, and D are a hydrocarbon moiety. The porphyrazine compounds, depending on the identity of A, B, C and D, are capable of complexing one to four metal ions to the periphery of the porphyrazine to form a multimetallic porphyrazine. Multimetallic porphyrazine compounds can be linked by the peripherally-complexed metal ions to form a linear, i.e., ribbon, polymer or a two-dimension, i.e., sheet polymer. The porphyrazine compounds, and the multimetallic complexes and polymers derived therefrom, are useful in, or as, magnet materials, molecular metal conductors, pharmaceuticals, imaging agents, and dyes.
