Peroxisome proliferator-activated receptor alpha (PPAR-α) is a ligand-activated nuclear receptor transcription factor that regulates the fatty acid β-oxidation. An in vitro assay identified the p-methoxy phenyl ureido thiobutyric acid derivative KSM-01 (IC50 = 0.28 ± 0.09 nM) having a higher affinity to activate PPAR-α than the PPAR-α agonist GW7647 (IC50 = 0.46 ± 0.19 nM). In this study, we report the synthesis and initial in vivo evaluation of [11C]KSM-01. The radiosynthesis was carried out by first alkylating the corresponding p-phenol precursor with [11C]MeI in DMF using NaOH, followed by deprotection of the t-butyl ester group by TFA, yielding [11C]KSM-01. SUV analysis of dynamic micro PET/CT imaging data showed that [11C]KSM-01 accumulation was ~2.0-fold greater in cardiac-specific PPAR-α overexpressing transgenic mice compared to wild-type littermates. The post-PET biodistribution studies were consistent with these results and demonstrated 2.5-fold greater radiotracer uptake in the heart of transgenic mice compared to the wild-type littermates. These results demonstrate the potential utility of PPAR-α agonists as PET radiopharmaceuticals.

2-Substituted histamines with G-protein-stimulatory activity

The cationic-amphiphilic 2-substituted histamines, 2-(2-chlorophenyl)histamine (2-ethanamine) and 2-(2-cyclohexylethyl)histamine, activate pertussis toxin-sensitive guanine nucleotide-binding proteins (G-proteins) of the Gi-subfamily by a receptor-independent mechanism.We studied structure-activity relationships of 2-substituted histamine derivatives for this G-protein activation using six known and 12 newly synthesized compounds.Elongation of the alkyl chain between imidazole and the ring system enhanced the potency and efficiency of substances in activating high-affinity GTP hydrolysis, ie the enzymatic activity of G-protein α subunits, in membranes of HL-60 leukemic cells.Cyclopentyl-, cyclohexyl- and norbornyl-substituted histamines were more effective and potent than phenyl-substituted histamines in mediating G-protein activation in HL-60 membranes and in activating reconstituted bovine brain Gi/Go-proteins.Our data show that the chain length and the type of ring system are important determinants for receptor-independent G-protein activation by 2-substituted histamines.With respect to histamine H1-receptors, most of the substances studied displayed weak antagonistic activity.

α,ω-Dibromoalkanes have been converted into mono-bromides R(CH2)nBr by reaction with the Grignard compounds RMgBr in THF in the presence of 5 mol percent of copper(I)bromide.In contrast to what is suggested in the original literature, this method has a limited scope.

Liquid-Crystalline Solvents as Mechanistic Probes. 21. Control of Norrish II 1,4-Biradical Reactivity by the Phase and Molecular Dimensions of an Ordered Solvent

The fates of four triplet 1,4-biradicals (produced as Norrish II intermediates during the irradiations of n-decanophenone, 2-cyclohexyl-1-(4-ethylphenyl)-1-ethanone, 4-cyclohexyl-1-phenyl-1-butanone, and 5-cyclohexyl-1-phenyl-1-pentanone) have been explored in crystalline-, smectic B-like, nematic-, and isotropic-phase solutions of trans,trans-4'-n-butyl-4-carbonitrile (BCCN).The experimental probe is the ratio of elimination to cyclization products.The results indicate that the ordered phases of BCCN behave as a molecular ruler with regard to solute conformations; the micromorphology of each phase imposes a different set of constraints upon the shapes of the 1,4-biradicals.A rationalization for the seemingly bizarre phase-dependent changes in product ratios, based upon the shapes and labilities of the 1,4-biradicals, is presented.
