AMG-009 is a novel, potent, orally bioactive, small molecule antagonist of prostaglandin D2, with IC50 of 3 nM and 12 nM for CRTH2 (chemoattractant receptor-homologous molecule expressed on Th2 cells) and DP (D prostanoid) receptors, respectively. For the treatment of allergic rhinitis and asthma, AMG 009 was undergoing preclinical development in the US.

Biological Activity
| Targets | DP ( IC50 = 3 nM ) |
| ln Vitro | AMG-009 prevents PGD2-induced down-modulation of CRTH2 on CD16 negative granulocytes (eosinophils) in human whole blood with a Ki of 1 nM. Additionally, AMG 009 has a Ki of 148 nM against PGD2-induced cAMP response mediated by DP in platelets in 80% of human whole blood. Guinea pig DP receptor-expressing cells (Ki=131 nM) in an assay for PGD2-induced cAMP response are inhibited by AMG 009 (IC50=3 nM)[1]. |
| ln Vivo | AMG 009 (3, 10 or 30 mg/kg, s.c.) in an acute guinea pig model causes a dose-dependent decrease in airway resistance triggered by PGD2 aerosol[1]. AMG 009, with a Kb of 82 nM, dramatically increases DP potency in a guinea pig model of PGD2-induced airway constriction[2]. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.) |
