Biological Activity

Description

IC₅₀ & Target

IC50: cyclic AMP and cyclic GMP accumulation^[2]

In Vitro

Phensuximide produce depolarization-induced accumulation of cyclic GMP or cyclic AMP levels with ID₅₀ values of 8.00 mM or 6.20 mM in incubated slices of mouse cerebral cortex^[2].
Phensuximide (0.5-2.0 mM) has the ability to competitively inhibit mephenytoin 4-hydroxylase activity in human liver microsomes, the K_i and K_m values are 559 μM and 235 μM, respectively^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Phensuximide (intraperitoneal injection; 1.25 mmol/kg; single dose) induces mild changes in renal function, including: trace hematuria, increased proteinuria and decreased paminohippurate uptake in Sprague-Dawley rats^[1].
Phensuximide (intraperitoneal injection; 0.3 or 0.6 mmol/kg; 5-7 days) results in transient hematuria and proteinuria, but no change in the other renal function parameters studied. It is concluded that phensuximide produces mild, transient renal effects in Fischer 344 rats, and that the Fischer 344 rat is a suitable model for studying phensuximide-induced toxicity to the urinary tract^[1].

Animal Model:

Fischer 344 rats^[1]
Dosage:

0.3 or 0.6 mmol/kg
Administration:

Intraperitoneal injection; 5-7 days
Result:

Induced urotoxicity following daily administration for 5-7 days in Fischer 344 rats.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
