Polyketide synthase 13-IN-3 (compound 41) is a potent inhibitor of polyketide synthase 13, demonstrating a minimum inhibitory concentration (MIC) range of 0.0625-0.125 μg mL against the M. tuberculosis strain H37Rv.
Phospho-Glycogen Synthase Peptide-2, a substrate for glycogen synthase kinase-3 (GSK-3), serves as a peptide substrate effective in the affinity purification of protein-serine kinases.
Chitin synthase inhibitor 2 (compound 2b) is a highly potent inhibitor of chitin synthase, with an IC50 value of 0.09 mM and a K i value of 0.12 mM. This compound exhibits antimicrobial activities in vitro and demonstrates synergistic or additive effects when combined with fluconazole or polyoxin B [1].
Polyketide synthase 13-IN-2 (comp 42) is a potent inhibitor of polyketide synthase 13 in Mycobacterium tuberculosis. It demonstrates a minimum inhibitory concentration (MIC) of 0.25 μg mL [1].
Glucosylceramide synthase-IN-3 (compound BZ1) is a highly potent, brain-penetrant, and orally active inhibitor of glucosylceramide synthase (GCS), exhibiting an IC50 value of 16 nM for human GCS. This compound, designated as Glucosylceramide synthase-IN-3, finds potential applications in Gaucher's disease research [1] [2].
GlcN-6-P Synthase-IN-1 (Compound 4d) is a potent inhibitor of Glucosamine-6-phosphate (GlcN-6-P) synthase, with an IC50 of 3.47 μM. This compound demonstrates remarkable antimicrobial activity and exhibits excellent penetration in the central nervous system. Additionally, GlcN-6-P Synthase-IN-1 is capable of inhibiting cytochrome P450, specifically the CYP3A4 isoform [1].
