Radiometal-Dependent Biological Profile of the Radiolabeled Gastrin-Releasing Peptide Receptor Antagonist SB3 in Cancer Theranostics: Metabolic and Biodistribution Patterns Defined by Neprilysin

Recent advances in oncology involve the use of diagnostic/therapeutic radionuclide-carrier pairs that target cancer cells, offering exciting opportunities for personalized patient treatment. Theranostic gastrin-releasing peptide receptor (GRPR)-directed radiopeptides have been proposed for the management of GRPR-expressing prostate and breast cancers. We have recently introduced the PET tracer 68Ga-SB3 (SB3, DOTA-p-aminomethylaniline-diglycolic acid-DPhe-Gln-Trp-Ala-Val-Gly-His-Leu-NHEt), a receptor-radioantagonist that enables the visualization of GRPR-positive lesions in humans. Aiming to fully assess the theranostic potential of SB3, we herein report on the impact of switching 68Ga to 111In/177Lu-label on the biological properties of resulting radiopeptides. Notably, the bioavailability of 111In/177Lu-SB3 in mice drastically deteriorated compared with metabolically robust 68Ga-SB3, and as a result led to poorer 111In/177Lu-SB3 uptake in GRPR-positive PC-3 xenografts. The peptide cleavage sites were identified by chromatographic comparison of blood samples from mice intravenously receiving 111In/177Lu-SB3 with each of newly synthesized 111In/177Lu-SB3-fragments. Coinjection of the radioconjugates with the neprilysin (NEP)-inhibitor phosphoramidon led to full stabilization of 111In/177Lu-SB3 in peripheral mouse blood and resulted in markedly enhanced radiolabel uptake in the PC-3 tumors. In conclusion, in situ NEP-inhibition led to indistinguishable 68Ga/111In/177Lu-SB3 profiles in mice emphasizing the theranostic prospects of SB3 for clinical use.

Novel vanadium complexes with rigid carboxylate ligands: Synthesis, structure and catalytic bromine dynamics of phenol red

In this work, by selecting appropriate ligands, novel vanadium complexes [VIVO(2,6-pdc)(Phen)]¡¤3H2O (1) and [(VIVO)(C5H5N2O2)2H2O]¡¤2H2O (2) (2,6-pdc = 2,6-pyridinedicarboxylic acid, Phen = 1,10-Phenanthroline monohydrate) were synthesized by the reaction of V2(SO4)3, 2,6-pdc and Phen (for 1), VO(acac)2 and C5H6N2O2 (for 2) via solution or hydrothermal methods. Two complexes were characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TG), UV-vis spectroscopy and the single crystal X-ray diffraction. Structural analyses reveal that the vanadium atom has distorted octahedral geometry in 1 and 2 with donor sets of N3O3 and N2O4, respectively. The complexes which catalyze the oxidation of the organic substrate phenol red in the presence of H2O2 and bromide exhibited catalytic bromination activity, and the reaction system is considered as an effective model for hydrogen peroxide determination. The reaction rate constant (k) for complexes 1 and 2 can be calculated as 2.13 ¡Á 102 and 2.64 ¡Á 102 (mol/L)?2s?1, respectively.

New 4-amino-N-alkylphthalimides as fluorescence probes for beta-cyclodextrin inclusion complexes and hydrophobic microdomains of amphiphilic systems

The synthesis and photophysical behaviour of a series of 4-amino-N-alkylphthalimides have been described. The complexation between beta-cyclodextrin and the different phthalimides has been studied by steady-state fluorescence. The association constant K depends strongly on the hydrophobicity of the alkyl substituent, and the K values vary between 115 M-1 and 19,000 M-1. The studied compounds have been used as fluorescent probes to determine the first and second association constants of surfactants with beta-cyclodextrin from competitive binding data. The results are compared with those given by other authors, and limitations of the method are discussed. 4-Amino-N-tert-butylphthalimide is also used as a sensor for following micellar aggregation process of surfactants and autoassociation of hydrophobically modified polymers. Values of critical micellar concentration (cmc) and critical aggregation concentration (cac) are determined, and comparison is made with pyrene.

Extra hydrogen bonding interactions by peripheral indole groups stabilize benzene-1,3,5-tricarboxamide helical assemblies

Benzene-1,3,5-tricarboxamide monomers derived from alkyl esters of tryptophan (BTA Trp) self-assemble into helices with an inner threefold hydrogen bond network surrounded by a second network involving the indole N-H groups. As a consequence of this extra stabilization of its helical assemblies, BTA Trp forms more viscous solutions than a range of ester and alkyl BTAs.

A comprehensive review on oxidative desulfurization catalysts targeting clean energy and environment

Harvesting clean energy from fuel feedstocks is of paramount significance in the field of environmental science. In this dynamic area, desulfurization provides a valuable contribution by eliminating sulfur compounds from fuel feedstocks to ensure the utilization of fuels without the emission of toxic sulfur oxides (SOx gases). Nonetheless, the inadequacy of the current industrial technique (hydrodesulfurization, HDS) in the removal of refractory sulfur (RS) compounds and the stringent rules imposed on the fuel sulfur level have kindled research on other desulfurization methods like oxidative desulfurization (ODS). With the capacity of eliminating RS compounds under mild conditions, ODS is endorsed as a suitable replacement or complementary to HDS. ODS, in general, consists of two steps: (i) oxidation and (ii) extraction. The oxidation of sulfur compounds is carried out using a suitable catalyst (hereafter termed as an ODS catalyst) in the presence of an oxidant. Choosing a suitable ODS catalyst for industrial applications is still a quest among the various types of catalysts reported so far. With this outline, herein, all the types of ODS catalysts along with their synthetic methods, reactivity and mechanistic insights are reviewed. The activity of ODS catalysts could be influenced by factors like the type of RS compound, solvent, fuel, etc. and those factors are reviewed. The effects of ionic liquids, light, and ultrasound on the performance of ODS catalysts are also briefly summarized. The opportunities and challenges for ODS catalysts are comprehensively explicated in the end. Through this review, systematic information about the types of ODS catalysts including the basic definition, preparative methods, reactivity and mechanism can be comprehended. Furthermore, this review reveals the merits and demerits related to highlighting catalytic ODS as a replacement or complementary to HDS.
