photolysis of 4 in acidic aqueous solution (pH < 3) resulted in a clean intramolecular photoredox reaction, via an enol intermediate, to give 10 (green compound; Φ ~ 0.2 at pH 1), which was too reactive for isolation or trapping by standard ArOH trapping agents such as aceticanhydride. These reactions may be viewed as a one-way photochemical intramolecular “redox switch” from quinone to hydroquinone

Inhibitors of indoleamine 2,3-dioxygenase (IDO) are provided as are pharmaceutical compositions containing such inhibitors as well as the use of such inhibitors and compositions for the treatment of a condition in a mammalian subject characterized by pathology of the IDO-mediated tryptophan metabolic pathway. Such conditions may involve suppression of T-cell mediated immune response or may directly result from depletion of tryptophan or accumulation of a product of tryptophan degradation. Specific disease conditions include cancer. IDO inhibitors of this invention are homologs of annulin A, annulin B or annulin C.
本研究提供了吲哚胺 2,3-二氧化酶(IDO)的抑制剂以及含有此类抑制剂的药物组合物,还提供了使用此类抑制剂和组合物治疗哺乳动物体内以 IDO 介导的色氨酸代谢途径病理学为特征的疾病的方法。此类病症可能涉及抑制 T 细胞介导的免疫反应,也可能直接导致色氨酸耗竭或色氨酸降解产物的积累。具体的疾病情况包括癌症。本发明的 IDO 抑制剂是鹅膏素 A、鹅膏素 B 或鹅膏素 C 的同源物。

Such conditions may involve suppression of T-cell mediated immune response or may directly result from depletion of tryptophan or accumulation of a product of tryptophan degradation. Specific disease conditions include cataracts, age-related yellowing in the eye, neurodegenerative disorders, mood disorders, cancer and various bacterial/viral infections. IDO inhibitors of this invention are substituted naphthalene and anthracene diones. Novel compounds of this invention include the following taurine-substituted naphthaquinone structure.

The present invention is related to the use of cells, such as stem cells or immune system cells, to deliver nanogels comprising an active agent to a desired site in the body. The present invention utilizes cells as a delivery system for active agents that are difficult to deliver, such as active agents with poor solubility, that degrade easily, or that are toxic to the body. The nanogels are preferably non-toxic and can optionally include a lytic agent to program apoptosis of the cell to deliver the nanogel and active agent to a desired sire within the body.
