The novel class of phenazine derivatives of the present invention represented by the general formula
where R, represents H or up to three substituents, at positions selected from 2 to 4 and 6 to 9, wherein any two or all of the substituents may be the same or different and the substituents are selected from
lower alkyl radicals;
lower alkyl radicals substituted by one or more of the same or different substituents selected from hydroxy, amino and ether functions;
OH,
SH;
OCH2Ph;
OPh;
N02;
halogen; CF3; amino;
NHSO2R2, NHCOR2, NHCOOR2, OR2 and SR2 (where R2 represents a lower alkyl radical which is unsubstituted or substituted by one or more of the same or different substituents selected from hydroxy, amino and ether functions); and
CONH(CH2)n'Y (where n' and Y' are as defined below), there being a maximum of one CONH(CH2)n'Y' group; or any two of R, at adjacent positions represent -CH=CH-CH=CH- as part of an extra benzene ring or -O-CH2-O- (methylenedioxy) and the third of R, has any one of the meanings given above with the exception of an OH at position 2;
Y and Y', which may be the same or different, each represents C(NH)NH2, NHC(NH)NH2 or NR3R4, where each of R3 and R4, which may be the same or different, represents H or a lower alkyl radical unsubstituted or substituted by one or more of the same or different substituents selected from hydroxy, amino and ether functions, or R3 and R4, together with the nitrogen atom to which they are attached, form a heterocyclic ring; and
n and n', which may be the same or different, each represents an integer from 2 to 6; and the acid addition salts, 5- and 10- mono-N-oxides and 5,10-di-N-oxides thereof, possess antibacterial and antitumour properties.
