p-APMSF hydrochloride
Based on 1 Customer Validation
p-APMSF (p-Amidinophenylmethylsulfonylfluoride) hydrochloride is a serine protease and trypsin inhibitor with the characteristic of rapid onset of action. p-APMSF hydrochloride reduces the enzymatic hydrolysis of recombinant human G-CSF in rat pulmonary mucosa. Combined intratracheal treatment with p-APMSF hydrochloride and Laureth-9 significantly enhances its absorption efficiency in rat lungs. Following intranasal administration, p-APMSF hydrochloride does not increase the concentration of recombinant human G-CSF in rat plasma, nor does it alter the effect of G-CSF on inducing an increase in total white blood cell count.

製品説明
体外実験
p-APMSF (4 mg/mL; 2 h) hydrochloride effectively inhibits trypsin activity in a cell-free system after 2 hours of incubation at room temperature, enabling the isolation of α2M-cytochrome c conjugates[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .
体内実験
p-APMSF hydrochloride (10 mM; intranasal) does not enhance rhG-CSF-induced increases in total leukocyte numbers or plasma rhG-CSF concentrations following intranasal co-administration in healthy rats[3].

Animal Model:Sprague-Dawley Rat (SD) (male, 8 weeks old, 250-300 g)[2]
-
Dosage:10 mM
-
Administration:intratracheal; single coadministered dose
-
Result:Increased plasma rhG-CSF concentration about 3-fold, from 3.9 to 11.7 ng/mL, at 30 minutes post-administration.
Increased AUC0-8 of rhG-CSF by more than 1.5-fold compared to intratracheal control.
When combined with Laureth-9, increased plasma rhG-CSF concentration at 30 minutes post-administration about 123-fold to 481.5 ng/mL.
Achieved a relative bioavailability of rhG-CSF of 73.6% versus intravenous administration and 172.8% versus subcutaneous administration.

-
Dosage:10 mM (in combination with rhG-CSF at 100 μg/kg)
-
Administration:intranasal
-
Result:Did not produce a significant increase in the AUC for the increase ratio of total leukocyte numbers compared to rhG-CSF administered alone.
Did not significantly increase plasma rhG-CSF concentrations relative to rhG-CSF administered alone.
