Histamine H3 receptor inverse agonists are known to enhance the activity of histaminergic neurons in brain and thereby promote vigilance and cognition. 1-{3-[3-(4-Chlorophenyl)propoxy]propyl}piperidine, hydrochloride (BF2.649) is a novel, potent, and selective nonimidazole inverse agonist at the recombinant human H3 receptor. On the stimulation of guanosine(More)
Phleomycins are glycopeptide antibiotics related to bleomycins nucleotide sequence of the Sh ble gene and its polylinker and tallysomycins which are active at low concentrations on both fragments. prokaryotic and eukaryotic cells (1). We have cloned a phleomycin-resistance gene (Sh ble) from the genomic DNA of REFERENCES Streptoalloteichus hindustanus (ATCC(More)
The seminal human dopamine D3 receptor (hD3R) ligand BP 897 has shown interesting properties during clinical trials. However, its lack of selectivity towards human adrenergic receptor impedes further development. Two approaches were followed to increase hD3R selectivity. The lead optimisation succeeded, we disclose here ligands with subnanomolar potency for(More)
Determinants of tetracycline resistance have been cloned from two different tetracycline-producing industrial strains of Streptomyces into Streptomyces lividans using the plasmid vector pUT206. Three plasmids, pUT250 and pUT260 with a 9.5 and a 7.5 kb insert respectively of Streptomyces rimosus DNA, and pUT270 with a 14.0 kb insert of Streptomyces(More)
