The invention provides novel prodrug compounds comprising a kinase inhibitor and a reductively-activated fragmenting aromatic nitroheterocycle or aromatic nitrocarbocycle trigger, where the compound carries a positive charge. In preferred embodiments, the compounds are of Formula I:
where: X is any negatively charged counterion; R
1
is a group of the formula —(CH
2
)
n
Tr, where Tr is an aromatic nitroheterocyde or aromatic nitrocarbocycle and —(CH
2
)
n
Tr acts as a reductively-activated fragmenting trigger; and n is an integer from 0 to 6; R
2
, R

may each independently be selected from aliphatic or aromatic groups of a tertiary amine kinase inhibitor (R
2
)(R
3
)(R
4
)N, or two of R
2
, R
3
, and R
4
may form an aliphatic or aromatic heterocyclic amine ring of a kinase inhibitor, or one of R
2
, R
3
, and R
4
may be absent and two of R
2
, R
3
and R
4
form an aromatic heterocyclic amine ring of a kinase inhibitor.
The compounds of the invention are useful in treating proliferative diseases such as cancer.
