FIELD: chemistry.
SUBSTANCE: invention relates to analogues of benzoquinone-containing ansamycins of formulae 
and 
,
in which radicals and symbols assume values given in the claim, and use thereof to treat and modulate proliferation-associated disorders such as cancer. The present invention describes a method of producing analogues of benzoquinone-containing ansamycins according to which benzoquinone is reduced to hydroquinone and bonded through reaction with a suitable acid.
EFFECT: high solubility and air stability of the obtained ammonium hydroquinone ansamycin analogue.
