Kinase experiment: | The receptor-expressing CHO cells are seeded into 24-well plates at a density of 4×104 cells/well and cultured for 1 day. The cells are then incubated with [5,6,8,9,11,12,14,15-3H]arachidonic acid (11 kBq/well) for 1 day and ished with DMEM supplemented with 20 mM HEPES and 0.2% BSA. The cells are then preincubated with the compounds (Sufugolix) at 37 °C for 60 min and the reaction is started by addition of LHRH (1 nM). After incubation at37 °C for 40 min, radioactivity in the medium is measured with a liquid scintillation counter[1]. |
Animal experiment: | Monkeys: Sufugolix (10 or 30 mg/kg, 3 mL/kg, n=3 for each group) is suspended in 0.5% methylcellulose containing 1.2% citric acid, or 0.5% methylcellulose containing 1.2% citric acid alone (3 mL/kg, n=3), are administered orally. Blood samples (heparin-plasma) are collected from a femoral vein 24 h before administration and 0, 2, 4, 8, 24, and 48 h after administration. LH concentrations in the plasma are measured by bioassays using mouse testicular cells[1]. |

Sufugolix is a gonadotropin-releasing hormone (GnRH) receptor antagonist (IC50 = 0.1 nM).1 Sufugolix inhibits GnRH-induced arachidonic acid release in CHO cells expressing human recombinant or monkey recombinant GnRH (IC50s = 0.1 and 10 nM, respectively), but not the rat GnRH receptor. It inhibits luteinizing hormone (LH) release stimulated by GnRH in monkey pituitary cells ex vivo (IC50 = 36 nM).2 Sufugolix (10 and 30 mg/kg) reduces increases in plasma LH following castration in male cynomolgus monkeys and lowers serum LH, estradiol, and progesterone levels in female cynomolgus monkeys when administered at a dose of 90 mg/kg.1,2

Challenges and opportunities of trapping ligands
Mol Pharmacol 2007 Aug;72(2):231-4.PMID:17522183DOI:10.1124/mol.107.038208
Because gonadotropin-releasing hormone (GnRH) analogs constitute an important class of therapeutics for various reproductive and hormone-dependent disorders, many novel compounds have been discovered and studied. Several orally active nonpeptide GnRH antagonists have recently gained increased attention. In the study published in this issue of Molecular Pharmacology, Kohout et al. (p. 238) used small-molecule TAK-013 (Sufugolix; developed previously by Takeda Chemical Industries) as a tool to elucidate the mechanism of its insurmountable antagonism. On the basis of receptor mutagenesis combined with molecular modeling, the authors hypothesized that certain amino acid sequences uniquely present in the human GnRH receptor amino terminus and extracellular loop 2 may form a "trap door" retarding dissociation of TAK-013. Such a trapping mechanism could be both ligand- and receptor species-specific. Although analogous models were previously proposed for other G protein-coupled receptors, the study by Kohout et al. (2007) provides an important advance in the GnRH antagonists field and an illustration of the fact that preclinical studies using animal models with nonhuman receptors may have very limited value in predicting drug efficacy in human disease. There are many examples showing that high-affinity protein, peptide, or nonpeptide agonists or antagonists have also enhanced clinical efficacy. However, there are also numerous studies indicating that very high receptor binding affinity is not a guarantee of drug efficacy and that other factors, including pharmacokinetic profile, ligand-induced receptor desensitization, and "trafficking," are critical in design and development of optimal drugs.
