NAOMInext is a software tool supporting medicinal chemists during hit-to-lead optimization. Starting from a co-crystallized small fragment, synthetic feasible lead compounds are generated directly within the proteins binding site. Thus, the software implicitly perfoms target-focused library design.
The NAOMInext software package  comes with an easy-to-use graphical user interface providing access to robust organic synthesis reaction.  The 3D viewer allows for inspection of available extension vectors. Beyond that, user-defined constraints may be easily defined to guide the growing process into a specific sub pocket. Published vendor catalogues can be downloaded from ZINC [3,4].
