Anti-leishmanial therapies: overcoming current challenges with emerging therapies. (PubMed, Expert Rev Anti Infect Ther) - "All three new treatments (Amphotericin-B, paromomycin and miltefosine) which underwent the clinical trials were repurposed drugs. The current pipeline for antileishmanial drugs is empty, with LXE 408 being the only potential drug reaching phase II clinical trial."

The 26 S proteasome in Entamoeba histolytica: divergence of the substrate binding pockets from host proteasomes. (PubMed, BMC Res Notes) - "This was strongly supported by significantly lower sensitivity to MG132 mediated inhibition of amoebic proteasome β5 subunit's chymotryptic activity compared to human proteasomes, also reflected in lower sensitivity of E. histolytica to MG132 for inhibition of proliferation. Selective inhibitors for visceral leishmaniasis, LXE408 and compound 8, docked well to this pocket. This functional and sequence-based analysis predicts differences between amoebic and host proteasomes that can be utilized to develop rationally designed, selective inhibitors against E. histolytica."

Small molecules as kinetoplastid specific proteasome inhibitors for Leishmaniasis: a patent review from 1998 to 2021. (PubMed, Expert Opin Ther Pat) - "LXE408 and GSK3494245 are two KSPIs in different phases of clinical trials. The KSPIs are promising next-generation orally active patient compliant drugs against kinetoplastid diseases, including leishmaniasis. However, the main challenge to discover the KSPIs will be the resistance development and their selectivity against the proteasome of eukaryotic cells."

Discovery and Characterization of Clinical Candidate LXE408 as a Kinetoplastid-Selective Proteasome Inhibitor for the Treatment of Leishmaniases. (PubMed, J Med Chem) - "Here, we describe the discovery and characterization of LXE408, a structurally related kinetoplastid-selective proteasome inhibitor currently in Phase 1 human clinical trials. Furthermore, we present high-resolution cryo-EM structures of the Leishmania tarentolae proteasome in complex with LXE408, which provides a compelling explanation for the non-competitive mode of binding of this novel class of inhibitors of the kinetoplastid proteasome."
