Discovery and SAR of cyclic isothioureas as novel NPY Y1 receptor antagonists
摘要:
A class of novel 2-aminobenzothiazoles have been identified as NPY Y-1 antagonists. Various N-heterocyclic substituted aminophenethyl-2-aminobenzothiazole analogs were synthesized to explore the SAR. Isothiourea analogs and ligands with high potency (K-i 30 nM) have been identified. (C) 2009 Elsevier Ltd. All rights reserved.
Histamine H3 and H4 receptor affinity of branched 3-(1H-imidazol-4-yl)propyl N-alkylcarbamates
摘要:
A series of imidazole-containing (non-)chiral carbamates were tested at human histamine H-3 receptor (H3R). All compounds displayed K-i values below 100 nM. A trend for a stereoselectivity at human H3R was observed for the chiral alpha-branched ligands. Selected compounds were also tested at human histamine H-4 receptor and showed moderate to weak affinities (118-1460 nM). (C) 2009 Elsevier Ltd. All rights reserved.

di-isocyanates. The obtained derivatives were assayed as activators of the enzyme carbonic anhydrase (CA, EC 4.2.1.1), due to the fact that histamine itself has this biological activity. Although inhibition of CAs has pharmacological applications in the field of antiglaucoma, anticonvulsant, anticancer, and anti-infective agents, activation of these enzymes is not yet properly exploited pharmacologically

biological waterchannels known for fast water transport (∼10(8)-10(9) molecules/s/channel) with ion exclusion. Few synthetic channels have been designed to mimic this high water permeability, and none reject ions at a significant level. Selectivewater translocation has previously been shown to depend on water-wires spanning the AQP pore that reverse their orientation, combined with correlated channel motions
