Definitions
- the present invention relates to porphyrin derivatives which have a microbicidal action.
- Porphyrins are photosensitizers which absorb electromagnetic radiation, preferably visible light, and thereby catalyze the formation of radicals and / or singlet oxygen from triplet oxygen. This radical mechanism partially or completely destroys living cells, opening up a way to combat harmful organisms.
- EP-A-0 390 743 porphyrins and phthalocyanines as insecticides and acaricides.
- US-A-4,648,992 discloses water-soluble phthalocyanine compounds which can be used as bleaching agents or also for disinfecting swimming pools.
- DE-A-196 06 082 relates to a pesticide which contains a photosensitizer of the tetrapyrrole and / or tetraazapyrrole series. In DE-A-196 06 081, similar tetrapyrrole photosensitizers are used to control bacteria in water.
- porphyrin derivatives show a microbicidal action even without the influence of electromagnetic radiation.
- R 1, R 2 , 3 and R 4 are each, independently of one another, optionally substituted alkyl or aralkyl radicals.
- the alkyl radical is preferably a d -C 3 o -alkyl radical. Short alkyl radicals with a chain length of up to 4 or longer radicals with 6 to 22 C atoms are particularly preferred.
- a preferred aralkyl group is the benzyl group.
- all of the radicals R 1 to R are short-chain alkyl radicals having 1 to 4 carbon atoms, in particular methyl groups.
- three of the radicals R 1 to R 4 are short-chain alkyl radicals with 1 to 4 carbon atoms, in particular methyl groups, and the fourth radical is a longer, linear alkyl radical with at least 6 carbon atoms, with a chain length of at least 10 carbon atoms Atom is more preferred.
- R 1, R 2 and R 3 are each a methyl group and R 4 is a C 6 -C 2 2 -alkyl radical or a benzyl group or a compound in which all the radicals R 1 to R 4 represent hexyl groups.
- the microbicidal activity is increased by introducing one or more longer alkyl chains.
- the claimed compounds can be used as microbicides, in particular bactericides.
- the compounds according to the invention can be prepared in an analogous manner to known porphyrin derivatives.
- porphyrins with different chemical structures were incubated in the dark with E. coli and S. aureus cells.
- the porphyrins were added to aqueous suspensions with a bacterial cell content of 10 8 per ml and stored in the dark at room temperature for 5 minutes.
- the amount of porphyrin bound to the cells was measured depending on the number of washing steps (the washing was carried out using physiological solutions) by chemical extraction followed by spectrophotofluorimetric determination.
- the survival rate of the bacterial cells after incubation with the various porphyrins was determined by diluting 0.3 ml of the suspension with 2.7 ml of the nutrient medium and recording the optical density at 650 nm as a function of time. The suspensions were at 37 ° C held. Percent growth inhibition was calculated based on a suspension of control cells treated with the same procedure but not added to the porphyrin.
