Description
OverviewA cell-permeable propynoic acid carbamoyl methyl amide (PACMA) that is more potent than PAO (Cat. No. 521000) in inhibiting PDI (protein disulfide isomerase) thioloxidoreductase activity (IC50 = 10 and 85 µM, respectively; 1h preincubation) by altering PDI secondary conformation via covalent modification of active site C(397)GHC(400) motif cysteines. Shown to inhibit the proliferation of human ovarian cancer cells in vitro (GI50 (72 h) = 0.32, 0.9, and 1.4 µM in OVCAR-3, OVCAR-8, and NCI/ADR-RES cultures, respectively), and suppress OVCAR-8 tumor growth in mice in vivo via either i.p. (100 mg/kg/5d/wk or 40 mg/kg/d) or p.o. (20 mg/kg/d to 200 mg/kg/d with 20 mg increment every 3 days; then 200 mg/kg/d til day 62). The commonly used PDI inhibitor Bacitracin (Cat. No. 1951) on the other hand is not suitable for in vivo studies due to its nephrotoxicity and low membrane permeability.

DescriptionA cell-permeable propynoic acid carbamoyl methyl amide (PACMA) that is more potent than PAO (Cat. No. 521000) in inhibiting PDI (protein disulfide isomerase) thioloxidoreductase activity (IC50 = 10 and 85 µM, respectively, in insulin aggregation assays; 1h preincubation) by altering PDI secondary conformation via covalent modification of either of the two cysteine residues within the active site C(397)GHC(400) motif. Shown to inhibit the proliferation of human ovarian cancer cells in vitro, including OVCAR-3, OVCAR-8, and the doxorubicin- (Cat. No. 324380) and paclitaxel- (Cat. No. 580555 & 580556) resistant NCI/ADR-RES (GI50 (72 h) = 0.32, 0.9, and 1.4 µM, respectively), and suppress OVCAR-8-derived tumor growth in mice in vivo via either i.p. (by 85%; 100 mg/kg/5d/wk for 3 wks, 40 mg/kg/d for 7 days, then no treatment til day 62) or p.o. (by 65%; 20 mg/kg/d to 200 mg/kg/d with 20 mg increment every three days; then 200 mg/kg/d til day 62). The commonly used PDI inhibitor Bacitracin (Cat. No. 1951) on the other hand is not suitable for in vivo studies due to its nephrotoxicity and low membrane permeability.
