Compounds of formula (I) and salts thereof: Wherein R1 represents methyl, ethyl, isopropyl or s-butyl; and R2 represents hydrogen or alkyl. R3 represents hydrogen, optionally substituted alkanoyl, optionally substituted alkenoyl, optionally substituted alkynoyl, alkylsulfonyl, or alkoxycarbonyl, or R2 and R3 together with the nitrogen atom to which they are attached form a saturated, optionally substituted 4- to 6-membered heterocyclic ring group. The moiety -a- together with the carbon atom to which it is attached forms a 3- to 6-membered cycloalkyl group. These compounds have anthelmintic, acaricidal and insecticidal activity.

[76Br]bromocaramiphen was prepared from the iodo-analogue by a Cu+ nucleophilic bromodeiodination exchange. The radiolabelling yield was 40-45%. The radiochemical and chemical purities assessed by radio-TLC and HPLC were 98%. The precursor, iodocaramiphen, was synthesized from commercially available 1-phenylcyclopentanecarboxylic acid with a 10% overall yield in a 5 step procedure. This synthesis includes the formation of 1-(p-nitrophenyl)-, 1-(p-aminophenyl)- and 1-(p-iodophenyl) cyclopemane carboxylic acid. In vivo studies in rats showed high uptake in brain. A 10% decrease was observed by coinjecting with the radiotracer a cold load of QNB, a non subtype selective muscarinic ligand. The metabolite study performed in the pons tissues indicated that there was still 92% of unchanged radiotracer 30 mm p.i. After coinjection of dextrometorphan, a sigma ligand, a reduction of the radioactivity uptake by 20 to 27% was observed in the pons, the cortex, the striatum and the cerebellum. These data suggest that [76Br]bromocaramiphen is not a potential probe for investigating the status of central M1 muscarinic receptors because of its high lipophilicity (log P7 4 = 2.4) and its affinity for sigma sites.
