EDI048
Based on 1 publication(s) in Google Scholar
EDI048 is an orally active, gut-restricted parasiticidal agent. EDI048 specifically binds to the ATP-binding site of Cryptosporidium phosphatidylinositol 4-kinase (CpPI (4) K), blocks parasite membrane biogenesis, arrests the pathogen at the schizont stage, and thus irreversibly clears the infection. EDI048 is rapidly converted to an inactive carboxylic acid metabolite via hepatic first-pass metabolism, with extremely low systemic exposure, good safety profile, and no cardiotoxicity, genotoxicity or off-target effects. EDI048 is used in studies of intestinal cryptosporidiosis in children.

Biological Activity
EDI048 (1 nM-20 μM; 5 min preincubation + 50 min incubation) potently inhibits wild-type Cryptosporidium parvum PI(4)K with an IC50 of 0.004 μM, and its activity depends on the conserved tyrosine residues Y705 and Y907 in the ATP-binding pocket of this enzyme[1].
EDI048 potently inhibits the asexual life cycles of Cryptosporidium parvum (48 h EC50=0.052 μM) and Cryptosporidium hominis (48 h EC50=0.050 μM) in HCT-8 cell cultures[1].
EDI048 (27 nM-20 μM; 72 h) exhibits antiparasitic activity against Cryptosporidium parvum in HCT-8 cell cultures. EDI048 achieves maximal parasite clearance (clearance rate >99%) at concentrations ≥27 nM, with a clearance half-life of approximately 15 h[1].
EDI048 (3× EC50; 4 h) exerts irreversible parasiticidal activity against Cryptosporidium parvum at the merozoite maturation stage (8-12 h post-infection) in HCT-8 cell cultures, but has no effect on the growth of the early trophozoite stage[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:HCT-8 human ileocaecal colorectal adenocarcinoma cells infected with Cryptosporidium parvum or Cryptosporidium hominis
-
Concentration:10-point 3-fold serial dilutions
-
Incubation Time:48 h (starting at 3 h post-infection)
-
Result:Inhibited Cryptosporidium parvum with an EC50 of 0.052 μM.
Inhibited Cryptosporidium hominis with an EC50 of 0.050 μM.
EDI048 (10 mg/kg; p.o.; once every 12 hours; for 7 consecutive days) significantly reduces fecal oocyst excretion and rapidly alleviates diarrhea symptoms in neonatal calves infected with cryptosporidiosis, with no recurrence of infection after treatment[1].
