Histone3-lysine79 (H3K79) methyltransferaseDOT1L has been found to be a drug target for acute leukemia with MLL (mixed lineage leukemia) gene translocations. A total of 55 adenosine-containing compounds were designed and synthesized, among which several potent DOT1Linhibitors were identified with Ki values as low as 0.5 nM. These compounds also show high selectivity (>4500-fold) over three other histone methyltransferases

A dynamiccombinatoriallibrary has been designed to produce a set of constituents among which one is able to self-complementarily direct its duplication. The overall molecular distribution in the library evolves along both kinetic and thermodynamic biases, leading to the amplification of the species that reproduces most efficiently and to the depletion of the other competitors.
