chitotriosidase

Closantel (R-31520), a salicylanilide anthelmintic compound, shows different anthelmintic spectra and obvious toxicity in mammals.

Closantel is a salicylanilide anthelmintic compound; exhibits different anthelmintic spectra and apparent toxicity in mammals.

OATD-01 is a highly active inhibitor of both Chitotriosidase (CHIT1) and acidic mammalian chitinase (AMCase).

OAT-2068 is a potent and selective inhibitor of mouse chitotriosidase (CHIT1) and displays a remarkable 143-fold mCHIT1 vs. mAMCase selectivity.

4-Methylumbelliferyl-β-D-N,N',N''-triacetylchitotrioside is a fluorogenic substrate for chitinases and chitotriosidases. 4-Methylumbelliferyl-β-D-N,N',N''-triacetylchitotrioside is cleaved by chitinases and chitotriosidases to release the fluorescent moiety 4-methylumbelliferyl (4-MU). 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases. It has been used to screen plasma samples for reduced chitotriosidase activity that may be indicative of lysosomal storage disorders.

Bisdionin C is a potent inhibitor of GH18 chitinase with an IC50 of 0.2 μM for A. fumigatus ChiB1. Bisdionin C inhibits human macrophage chitotriosidase(HCHT, IC50 = 8.3 μM) and acidic mammalian chitinase (AMCase, IC50 = 3.4 μM).

Argifin is a sub-nanomolar chitinase inhibitor produced by soil microorganisms (IC50: 0.025 μM, 6.4 μM, 1.1 μM, and 4.5 μM for SmChiA [Serratia marcescens chitinase A], SmChiB, Aspergillus fumigatus chitinase B1, and human chitotriosidase).
