The ␣ v ␤ 3 integrin is an important cell adhesion receptor involved in tumor-induced angiogenesis and tumor metastasis. Here we describe the 18 F-labeling of the RGD-containing glycopeptide cyclo(-Arg-Gly-Asp-D-Phe-Lys(sugar amino acid)-) with 4-nitrophenyl 2-[ 18 F]fluoropropionate and the evaluation of this compound in vitro and in tumor mouse models.
1. The effects of anandamide on [3H]-acetylcholine release and muscle contraction were studied on the myenteric plexus-longitudinal muscle preparation of the guinea-pig ileum preincubated with [3H]-choline. 2. Anandamide increased both basal [3H]-acetylcholine release (pEC(50) 6.3) and muscle tone (pEC(50) 6.3). The concentration-response curves for(More)
The effects of capsaicin on [3H]acetylcholine release and muscle contraction were studied on the myenteric plexus-longitudinal muscle preparation of the guinea-pig ileum preincubated with [3H]choline. Capsaicin concentration-dependently increased both basal [3H]acetylcholine release (pEC50 7.0) and muscle tone (pEC50 6.1). The facilitatory effects of(More)
The effects of the nitric oxide (NO) donor S-nitroso-N-acetyl-DL-penicillamine (SNAP) and the NO synthase inhibitor L-N(G)-nitroarginine (L-NOARG) on the electrically evoked [(3)H]-acetylcholine release were studied in an epithelium-free preparation of guinea-pig trachea that had been preincubated with [(3)H]-choline. SNAP (100 and 300 microM) caused small(More)
