Description: High affinity protein disulfide isomerase (PDI) modulator
Chemical Name: 2-[[4-(Cyclopropylcarbonyl)-1-piperazinyl]methyl]-1,2-benzisothiazol-3(2H)-one
Purity: ≥98% (HPLC)
Biological Activity for LOC14
LOC14 is a high affinity allosteric inhibitor of protein disulfide isomerase A3 (PDIA3) modulator (Kd = 62 nM, IC50 = 5 μM). In an animal model of Huntington's disease LOC14 extends survival, improves motor function, reduces ER stress from mHTT and preserves dopamine and DARPP32 levels. LOC14 is neuroprotective and rescues medium spiny neurons from neurodegeneration. LOC14 also decreases influenza A protein production in cells (IC50 = 4.97 μM).

PDI inhibitor LOC14 inhibits platelet spreading over fibrinogen.
By
Renato Gaspar on 05/11/2019
Assay Type: Ex Vivo
Species: Human
Cell Line/Tissue: Platelets
Washed platelets (2 x 10ˆ7 platelets/mL) were incubated in absence or presence of LOC14 (0.1, 1 and 10 µM) for 10 minutes at 37°C, then 300 µL of the solution was dispensed on a fibrinogen (100 µg/mL)-coated coverslip for 45 minutes at 37°C. Non-adhered platelets were removed and the coverslip washed three times with PBS. Adhered platelets were fixed using 0.2% paraformaldehyde for 10 minutes. This solution was then removed and coverslips washed three times with PBS before the addition of 0.1% (v/v) Triton-X to permeabilise the cells. After removal of Triton-X and further washes using PBS, platelets were stained with Alexa Fluor 488-conjugated phalloidin (1:1000 v/v) for 1 hour in the dark at room temperature. Coverslips were mounted onto microscope glass slides and imaged using a 100x oil immersion lens on a Nikon A1-R Confocal microscope.
