 Development of potent small molecule inhibitors of protein?protein interactions with optimized druglike properties represents a challenging task in lead optimization process. Here, we report synthesis and structure-based optimization of new thienopyrimidine class of compounds, which block the protein?protein interaction between menin and MLL fusion proteins that plays an important role in acute leukemias with <
 i>
 MLL<
 /i>
  translocations. We performed simultaneous optimization of both activity and druglike properties through systematic exploration of substituents introduced to the indole ring of lead compound <

 /b>
  (MI-136) to identify compounds suitable for in vivo studies in mice. We report this work resulted in the identification of compound <

  (MI-538), which showed significantly increased activity, selectivity, polarity, and pharmacokinetic profile over <

  and demonstrated a pronounced effect in a mouse model of MLL leukemia. This study, which reports detailed structure?activity and structure?property relationships for the menin?MLL inhibitors, demonstrates challenges in optimizing inhibitors of protein?protein interactions for potential therapeutic applications.
