  • Investigation of novel drug targets such as DNA repair enzymes, peptide deformylase, and dopamine D3 receptors.

    • Main Results:

    • Targeting DNA repair enzymes offers an advantage over targeting viral proteins by preventing resistant mutant emergence.
    • Improved understanding of IBD pathophysiology has spurred increased therapeutic development.
    • Peptide deformylase inhibitors show promise for treating bacterial infections and cancer.
    • Dopamine D3 receptors are identified as attractive targets for alcoholism therapy due to their role in alcohol dependency.

    Conclusions:

    • Diverse strategies are advancing drug discovery across multiple therapeutic areas.
    • Targeting host-related mechanisms, like DNA repair, can circumvent resistance.
    • Novel targets offer potential for treating complex diseases including IBD, infections, cancer, and substance abuse.
