ABSTRACT

Introduction: Leukemia is a collection of highly heterogeneous cancers that arise from neoplastic transformation and clonal expansion of immature hematopoietic cells. Post-treatment recurrence is high, especially among elderly patients, thus necessitating more effective treatment modalities. Development of novel anti-leukemic compounds relies heavily on traditional in vitro screens which require extensive resources and time. Therefore, integration of in silico screens prior to experimental validation can improve the efficiency of pre-clinical drug development.

Areas covered: This article reviews different methods and frameworks used to computationally screen for anti-leukemic agents. In particular, three approaches are discussed including molecular docking, transcriptomic integration, and network analysis.

Expert opinion: Today’s data deluge presents novel opportunities to develop computational tools and pipelines to screen for likely therapeutic candidates in the treatment of leukemia. Formal integration of these methodologies can accelerate and improve the efficiency of modern day anti-leukemic drug discovery and ease the economic and healthcare burden associated with it.

Article highlights

  • Molecular docking, transcriptomic profiling, and network analysis have been applied to computationally screen for novel anti-leukemia drugs.

  • Molecular docking studies allow researchers to screen through millions of small-molecules given that a drug target is known.

  • Transcriptomic profiling compares drug treatment gene expression profiles with disease profiles to identify novel candidates without requiring knowledge of the drug targets.

  • Network analysis of somatic and germline variants in leukemia can identify novel drug targets

  • Integration of these approaches into drug discovery pipelines can increase the efficiency of the drug screening process
