It's association with severe myelotoxicity lead to the end of its development in favour of \u03b1-halogenoacrylamide derivatives such as [brostallicin], which have a favourable cytotoxicity/myelotoxicity ratio. Newer generations of DNA minor groove binding agents can more specifically recognize base pair sequences."}]
