Biological Activity

Description ONO-7300243 is a novel, potent LPA1(Lysophosphatidic Acid Receptor) antagonist with an IC50 of 160 nM.
LPA1 [1]
(Cell-free assay)
0.16 μM
In vitro

Although ONO-7300243 showed only modest in vitro activity (IC50 = 0.16 μM), it showed much stronger effects in vivo (88% inhibition at 10 mg/kg i.d., 62% inhibition at 3 mg/kg i.d.). ONO-7300243 showed good membrane permeability and good metabolic stability against rat liver microsomes[1].

In vivo ONO-7300243 inhibited the LPA-induced IUP(intraurethral pressure) increase in a dose-dependent manner (ID50 = 11.6 mg/kg p.o.) up to 1 h after dosing. Significant effects were observed at 10 and 30 mg/kg (p<0.05 vs vehicle). ONO-7300243 (30 mg/kg, p.o.) led to a significant decrease in the IUP in conscious rats without LPA stimulation compared with the vehicle without affecting the mean blood pressure (MBP). In a a rat pharmacokinetic study, ONO-7300243 showed a rapid clearance (CLtot = 15.9 mL/min/kg at 3 mg/kg i.v.) and a short half-life (0.3 h)[1].

  • Incubation Time: --
  • Method:

    Chinese hamster ovary (CHO) cells stably expressing human LPA1 were seeded at a density of 2×104 cells per well into 96-well plates and cultured in the culture medium (F-12 Nutrient Mixture (HAM) containing 10% FBS) in a CO2 incubator (37ºC, 5% CO2, 95% air) for 2 days. Load buffer (culture medium containing 5 µM Fura2-AM, 10 mM HEPES (pH 7.55) and 2.5 mM probenecid) was added in each well and incubated in the CO2 incubator for 1 hour. After the load buffer was removed, cells were rinsed with assay buffer at room temperature, and the assay buffer was added to the cells. In the experiment of LPA1 antagonist assay, intracellular Ca2+ concentration was monitored using a fluorescence drug screening system to measure the ratio of fluorescence intensities (f340/f380) at 500 nm. After pretreatment of the antagonists, lysophosphatidic acid (LPA, final 100 nM) was added to the cells. The inhibition rate (%) of the antagonists was calculated from the peak ratio of LPA after treatment of compounds and that of control (DMSO). Furthermore, a non-linear regression analysis was performed using the Sigmoid Emax Model to estimate IC50 values.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
