PD 151746
Based on 7 publication(s) in Google Scholar
PD 151746 is a selective calpain-1 inhibitor with an IC50 of 260 nM. PD 151746 binds μ-calpain Ca2+-binding sites, and shows selectivity over cathepsin B, papain, trypsin, thermolysin, and basal calcineurin. PD 151746 reduces Oxidized low-density lipoprotein (oxLDL)-induced cytotoxicity, apoptotic DNA fragmentation, and blocks IL-1α maturation. PD 151746 can be used for the research of atherosclerosis and psoriasis.

PD 151746 potently and selectively inhibits μ-calpain with an apparent Ki of 0.26 μM, shows 20-fold selectivity over m-calpain[1].
PD 151746 (10 μM; 2 h) effectively inhibits calpain activity in Maitotoxin-treated human neuroblastoma SH-SY5Y cells[1].
PD 151746 (2-20 μM; 24 h) dose-dependently reduces oxLDL-induced cytotoxicity in HMEC-1 cells[2].
PD 151746 (2-20 μM; 12 h) significantly reduces oxLDL-induced apoptotic nucleosomal DNA fragmentation in HMEC-1 cells at 20 μM[2].
PD 151746 (20 μM; 20 h) inhibits oxLDL-induced calpain-mediated cleavage of α-fodrin in HMEC-1 cells[2].

Cell Line:HMEC-1
-
Concentration:2; 20 μM
-
Incubation Time:24 h

Cell Line:HMEC-1
-
Concentration:20 μM
-
Incubation Time:20 h

Result:Prevented oxLDL-induced formation of the calpain-specific 150 kDa α-fodrin fragment.
Reduced the ratio of calpain-generated to caspase-generated α-fodrin fragments (A150/A120) from 1.99 in oxLDL-only treated cells to a level consistent with untreated cells.\n
Prevented oxLDL-induced reduction of full-length 22 kDa Bid.
Maintained the ratio of Bid to α-tubulin at a level comparable to untreated control cells.
