FIELD: chemistry, biochemistry.
SUBSTANCE: invention relates to field of biotechnology, namely to bacteriochlorophyll derivatives and can be used for medical and diagnostic purposes. Anion-containing water-soluble tetracyclic and pentacyclic bacteriochlorophyll (Bchl) derivatives contain one, two or three negatively charged groups and/or acid groups, which transform into negatively charged groups at physiological pH. Obtained derivatives are used for photodynamic therapy and for tumor diagnostics, as well as for killing cells or infectious agents.
EFFECT: increasing selectivity of binding with target in photodynamic therapy and diagnostics.
