In the course of our investigations on Strychnos usambarensis leaves in order to isolate isostrychnopentamine, the main alkaloid responsible for the antiplasmodial activity of the plant, a new tertiary indolic alkaloid has been isolated: 17-O-acetyl, 10-hydroxycorynantheol 1. Its structure was determined by means of spectroscopic and spectrometric methods such as UV, IR, CD, NMR and ESI-MS. 17-O-acetyl, 10-hydroxycorynantheol 1 is one of the most active monomeric indole alkaloid known to date showing an in vitro activity against Plasmodium falciparum close to 5 µM and a high selectivity.

Calix[4]arene compound 0118 , a topomimetic of the antiangiogenic amphipathic peptide anginex targeting galectin-1, is currently in Phase I clinical trials with terminal cancer patients. Radiolabelled analogues of compound 0118 may serve as a development tool in PK/PD studies of this class of calix[4]arene compounds, and may prove highly valuable for patient stratification and therapy monitoring. So far, such radiotracers have not been described. In this work, we have designed compound 0118 analogues containing a terminal alkyne functional group for introduction of an F-18 label via Cu(I)-catalyzed 1,3-dipolar cycloaddition of 2-[18F]fluoroethylazide.

OBJECTIVE: This work reports on musculoskeletal uptake of (18)F-FPRGD2, targeting the integrin alphavbeta3, in patients who had undergone (18)F-FPRGD2 positron emission tomography combined with computed tomography (PET/CT) for oncologic purposes. METHODS: Whole-body (18)F-FPRGD2 PET/CT images of 62 cancer patients were retrospectively reviewed to detect foci of musculoskeletal (18)F-FPRGD2 uptake. For 37 patients, a FDG PET/CT performed in clinical settings was available. In each joint with an abnormal uptake, the maximum standardized uptake value (SUVmax) was estimated. RESULTS: A total of 260 musculoskeletal foci of (18)F-FPRGD2 uptake were detected. Most common sites of uptake were joints and discs (n = 160; 61.5 %), entheses (osteotendinous and osteoligamentous junctions; n = 55; 21.2 %) and recent fractures (n = 18; 6.9 %). In addition, 27 (10.4 %) miscellaneous foci were detected. Out of the 146 lesions for which a FDG PET was available, 63 % showed both (18)F-FPRGD2 and FDG uptake, 33.6 % did not show FDG avidity and 3.4 % showed only FDG uptake. The uptake intensity of the 92 lesions positive with (18)F-FPRGD2 and FDG was similar with both radiopharmaceuticals, but the target-to-background (blood pool or muscle) ratios were significantly higher with (18)F-FPRGD2 than with FDG (p < 0.0001). CONCLUSION: The (18)F-FPRGD2 uptake in joints, spine degenerative diseases and tendons was highly prevalent in our population. Up to one-third of (18)F-FPRGD2 foci showed no FDG uptake suggesting that (18)F-FPRGD2 signal may not be related to inflammatory angiogenesis only. [less ▲]

This study investigated the feasibility of ordered subsets expectation maximisation (OS-EM) reconstruction of pinhole single-photon emission tomography (SPET) acquired with a tilted detector head and a 180 degrees orbit. Phantom and patient data were recorded using a standard single-head camera. Reconstructions were performed using a dedicated OS-EM algorithm. Reconstructed images of line, uniformity and Picker's thyroid phantoms showed that the geometry, physical size and uniformity of the radioactive objects were preserved. For the range of radius corresponding to the patient studies, the measured full-widths at half-maximum lay between 4.90+/-0.25 mm and 6.05+/-0.25 mm. Finally, the gain in resolution associated with the use of the pinhole collimator instead of a parallel-hole collimator was highlighted in a parathyroid exploration and in a shoulder bone study.
