Biological Activity

Description

KP136 (AL136) is an orally effective antiallergic agent. The IC₅₀ is 76.1 μg/mL for histamine release and 63 ug/mL for degranulation^[1].

IC₅₀ & Target

Histamine release^[1]

All Histamine Receptor Isoforms :

In Vitro

KP136 (0.01 μg/mL) inhibits this histamine release and degranulation in a dose-dependent manner, confirming that it is an inhibitor of mast cell activation. The IC₅₀ is 76.1 μg/mL for histamine release and 63 ug/mL for degranulation^[1].

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

In Vivo

C4C at 0.2 mg/kg produces an equipotent effect to 1 mg/kg KP136 (KP-136) or 5 mg/kg DSCG. However, C4C is less effective by the oral route because it only produces a maximum inhibition of about 35% even at the high dose of 100 mg/kg, whereas KP136 shows an overt inhibitory effect of about 66% at the oral dose of 2 mg/kg. On the other hand, KP136 (1 mg/kg, i.v.) also remarkably inhibits 5-h homologous PCA, having an activity similar to that of C4C^[1].

Help & FAQs

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.
