Substituting a pyridine ring for a benzene ring in the acylation agent N-succinimidyl 3-iodobenzoate has resulted in a useful approach for the radiohalogenation of monoclonal antibodies, peptides, and labeled biotin conjugates. It was hypothesized that such a substitution in m-iodobenzylguanidine

Two 5-substituted derivatives of nicotine (nicotinic acetylcholine receptor: K(i)=2.4 nM) were synthesized and evaluated: 5-bromonicotine (K(i)=6.9 nM) and 5-methoxynicotine (K(i)=14.3 nM). Despite their high affinity, neither 5-bromonicotine nor 5-methoxynicotine mimicked nicotine in producing antinociceptive (tail-flick, hotplate), hypolocomotor, or hypothermic effects

Two types of monoclonal antibodies were used for the determination of nicergoline in biological matrices. The antibodies were prepared with the hydrolysis products 5-bromonicotinic acid and 1-methyl-10 alpha-methoxydihydrolysergol after hemisuccinoylation to haptens. The current amide bond-generating methods (mixed anhydride-, carbodiimide-
A strategy for lead identification of new agonists of GPR109a, starting from known compounds shown to activate the receptor, is described. Early compound triage led to the formulation of a binding hypothesis and eventually to our focus on a series
