So far, the chemical array system has been applied to identify compounds that interact with physiologically essential molecules including carbonic anhydrase II, MDM2, MTH1, trichothecene 3-O-acetyltransferase, and matrix metalloproteinase that may serve as leads for inhibitors of glaucoma, carcinogenesis, mycotoxin, and cancer metastasis29–33. The gene discussed is NUDT1; the disease is cancer.
