Abstract

The invention relates to novel hematoporphyrin monofluoroalkyl diether (I) and fluorophenyl alkyl diether derivatives (II) and application thereof in the field of medicines. The compound has the following structure. The invention relates to the field of photosensitive drugs and photodynamic therapy, in particular to novel hematoporphyrin monofluoroalkyl diether and fluorophenyl alkyl diether derivatives and application thereof in the field of medicines. The prepared compound is single in component, stable in property, controllable in quality, simple and convenient in preparation method and relatively good in photodynamic activity, and can be used as a photodynamic therapy drug for diseases such as tumors, retinal macular degeneration, actinic keratosis, nevus flammeus and condyloma acuminatum.

Description

technical field [0001] The invention relates to photosensitizing drugs and photodynamic therapy, in particular to a class of novel hematoporphyrin monofluoroalkyl diether and fluorophenyl alkyl diether derivatives and their application in the medical field. Background technique [0002] Photodynamic therapy (PDT), as a new method for the treatment of tumors, macular degeneration, actinic keratosis, port wine stains, condyloma acuminatum and other diseases (Chem. Rev. 2019, 119, 797-828), has been clinically Remarkable achievements have been made in the treatment. The mechanism is that after the photosensitizer enters the body, it selectively gathers in the target tissue along with the blood circulation, and then irradiates the target tissue with a laser of a certain wavelength to generate active oxygen (such as singlet oxygen) Act on target cells, causing cell metabolism disorder, thereby killing target cells. [0003] In photodynamic therapy, photosensitizing drugs (also k...
