These compounds are analogues of x1093. What is desirable about this molecule is that it is able to occupy the only deep binding pocket (containing tyrosine54) with the N-methyl piperazine moiety and, at the same time, with its pyrrolopyridine moiety, occupy the binding pocket containing cysteine145 and histidine162. The amino piperidine is longer than the piperazine, allowing for potential H-bonding to tyrosine54.
