agh-107 agh-107 agh-107 is a potent, selective, water-soluble and brain penetrant full agonist at the 5ht7 serotonin receptor. agh-107 is one of the few examples of low-basicity aminergic receptor agonists, which may underlie its high selectivity over the related central nervous system targets. agh-107 was found to reverse the impairment in novel object recognition caused by mk-801 in mice. the relatively short half-life in rodents inhibited its use as a molecular probe. agh-107identifiers iupac name 3-(3-ethylimidazol-4-yl)-5-iodo-1h-indole pubchem cid138691314chemical and physical dataformulac13h12in3molar mass337.164 g·mol−13d model (jsmol)interactive image smiles ccn1cncc1-c1cc2ccc(i)cc12
