The invention relates to 12-aza-epothilones of formula (I)
wherein R1 is optionally substituted antinocarbonyl, optionally substituted atkoxycarbonyl, aryloxycarbonyl or heteroaryl and R2 is a radical of formula (II)
wherein X is S, O, NR4, -C(R5)=N-, -N=C(R5)- or -C(R5)=C(R6)-: and R3, R4, R5 and R6 are as defined in the specification, and which is bound to the radical of formula (I) at one of the two carbon atoms indicated with an asterix; a method of manufacture of these compounds, new intermediates, pharmaceutical preparations containing these compounds, and the use of these compounds in the treatment of proliferative diseases. These 12-aza-epothilones are highly potent cytotoxic compounds and are active against multidrug-resistant cell lines and tumours.
