Mesoporphyrin IX is a porphyrin compound that is structurally similar to protoporphyrin IX, a key component of heme. It differs from protoporphyrin IX by the presence of two ethyl groups instead of two vinyl groups at positions 2 and 4. Mesoporphyrin IX can be synthesized through chemical reduction of protoporphyrin IX. It exhibits fluorescence properties and has been investigated for its potential applications in photodynamic therapy, a cancer treatment modality. The compound's fluorescence allows for targeted delivery and activation of cytotoxic reactive oxygen species upon excitation with light. This makes it a promising candidate for the development of novel cancer therapies. Research on mesoporphyrin IX also focuses on its ability to interact with various biological targets, including proteins and nucleic acids, which could lead to further therapeutic applications.'

Kaposi Sarcoma [description not available] | 0 | 2.94 | 1 | 0 |
Sarcoma, Kaposi A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause. | 0 | 2.94 | 1 | 0 |

Ischemic Attack, Transient Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6) | 0 | 1.99 | 1 | 0 |

Myocardial Ischemia A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION). | 0 | 2 | 1 | 0 |

Porphyrias A diverse group of metabolic diseases characterized by errors in the biosynthetic pathway of HEME in the LIVER, the BONE MARROW, or both. They are classified by the deficiency of specific enzymes, the tissue site of enzyme defect, or the clinical features that include neurological (acute) or cutaneous (skin lesions). Porphyrias can be hereditary or acquired as a result of toxicity to the hepatic or erythropoietic marrow tissues. | 0 | 1.97 | 1 | 0 |
