The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Picolinamide(SMILESS: O=C(N)C1=NC=CC=C1,cas:1452-77-3) is researched.Computed Properties of C12H11NO. The article 《Development of radiofluorinated nicotinamide/picolinamide derivatives as diagnostic probes for the detection of melanoma》 in relation to this compound, is published in International Journal of Molecular Sciences. Let’s take a look at the latest research on this compound (cas:1452-77-3).
Regarding the increased incidence and high mortality rate of malignant melanoma, practical early-detection methods are essential to improve patients′ clin. outcomes. In this study, we successfully prepared novel picolinamide-benzamide (18F-FPABZA) and nicotinamide-benzamide (18F-FNABZA) conjugates and determined their biol. characteristics. The radiochem. yields of 18F-FPABZA and 18F-FNABZA were 26 ± 5% and 1 ± 0.5%, resp. 18F-FPABZA was more lipophilic (log P = 1.48) than 18F-FNABZA (log P = 0.68). The cellular uptake of 18F-FPABZA in melanotic B16F10 cells was relatively higher than that of 18F-FNABZA at 15 min post-incubation. However, both radiotracers did not retain in amelanotic A375 cells. The tumor-to-muscle ratios of 18F-FPABZA-injected B16F10 tumor-bearing mice increased from 7.6 ± 0.4 at 15 min post-injection (p.i.) to 27.5 ± 16.6 at 3 h p.i., while those administered with 18F-FNABZA did not show a similarly dramatic increase throughout the exptl. period. The results obtained from biodistribution studies were consistent with those derived from microPET imaging. This study demonstrated that 18F-FPABZA is a promising melanin-targeting positron emission tomog. (PET) probe for melanotic melanoma.
