Compounds and method for PDT of intimal hyperplasia and other diseases

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.

Pharmaceutical composition for treating atherosclerosis, and preparation method and application thereof

The invention belongs to the field of biology, and discloses a pharmaceutical composition for treating atherosclerosis, and a preparation method and application thereof. The active components of the pharmaceutical composition comprise ginkgo leaf extract and earthworm fibrinolysin, wherein the dose ratio of the ginkgo leaf extract to the earthworm fibrinolysin is (200-900g):(800000-2700000uku). Proven by tests, after the pharmaceutical composition disclosed by the invention is used, compared with a single drug treatment group and a model group, the relative area of the aorta atheromatous plaque is notably reduced, macroscopic and microscopic pathological changes are the lightest, and the animal morbidity is the lowest. The levels of LDL (low density lipoprotein), TC (total cholesterol) and TG (triglyceride) of the pharmaceutical composition treatment group are notably reduced compared with the model group, and the level of HDL (high density lipoprotein) of the high-dose pharmaceutical composition group is notably raised. The pharmaceutical composition disclosed by the invention has two single drugs synergic in combined action property, has the effect of treating both principal and secondary aspects of disease on atherosclerosis, and is clinically proven especially by patients who have coronary heart disease and moderate and severe coronary artery stenosis.
