Acriflaviniumchlorid is a mixture of substances, which as a drug ( antiseptic in the mouth and throat ) applies. It was patented in 1929 by the I. G. colors.

Chemically, it involves a mixture of about two-thirds of 3,6 -diamino -10 - methylacridiniumchlorid ( C14H14ClN3 ) and about one third 3.6 - Diaminoacridinhydrochlorid ( C13H12ClN3 ), of which the former is a quaternary ammonium compound. Both of these compounds are derivatives of acridine.

Effect

Acridine derivatives are active against gram-positive bacteria. Acriflaviniumchlorid intercalates into nucleic acids and thus inhibits the growth of bacteria and viruses. According to a study by the International Agency for Research on Cancer ( IARC ), it is however probable carcinogen.

Other uses

Acriflaviniumchlorid is also used for vital staining. Earlier it was 3,6 -diamino -10 - methylacridiniumchlorid under the name trypaflavine as a means against African Trypanosomiasis ( " sleeping sickness "), whose excitation is one of the trypanosomes used.
