And the article contained the following:

We describe the discovery and optimization of a novel series of furo[3,2-d]pyrimidines as G protein-coupled receptor 119 agonists. Agonistic activity of 4 (EC50 = 129 nM) was improved by replacing the intramol. hydrogen bond between the fluorine atom and the aniline hydrogen in the head moiety with a covalent C-C bond to enhance conformational restriction, which consequently gave a lead compound 12 (EC50 = 53 nM). Optimized compound 26, which was identified by the further optimization of 12, exhibited potent activity (EC50 = 42 nM) with improved clearance in liver microsomes and induced a 33% reduction in blood glucose area under the curve at a dose of 10 mg/kg in an oral glucose tolerance test in C57BL/6N mice. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Application of 98946-18-0

On December 7, 2020, Zhao, Ruiyue; Ploessl, Karl; Zha, Zhihao; Choi, Seokrye; Alexoff, David; Zhu, Lin; Kung, Hank F. published an article.Category: chlorides-buliding-blocks The title of the article was Synthesis and Evaluation of 68Ga- and 177Lu-Labeled (R)- vs (S)-DOTAGA Prostate-Specific Membrane Antigen-Targeting Derivatives. And the article contained the following:

Prostate-specific membrane antigen (PSMA) is overexpressed in prostate cancer cells and therefore is an attractive target for prostate cancer diagnosis and radionuclide therapy. Recently, published results from clin. studies using a new PSMA-targeting PET imaging agent, [68Ga]Ga-PSMA-093 ([68Ga]Ga-HBED-CC-O-carboxymethyl-Tyr-CO-NH-Glu), support the development of this agent for the diagnosis of prostate cancer. In this study, the HBED-CC chelating group in PSMA-093 was replaced by stereoselective (R)- or (S)-DOTAGA. This chelating group serves not only for chelating 68Ga but is also amendable for complexing other radioactive metals for radionuclide therapy. The corresponding optically pure (R)- and (S)-[68Ga/177Lu]-DOTAGA derivatives, (R)-[68Ga/177Lu]-13 and (S)-[68Ga/177Lu]-13, were successfully prepared Comparison of radiolabeling, binding affinity, cell uptake, and biodistribution between the two isomers was performed. Radiolabeling of (R)-[177Lu]Lu-13 and (S)-[177Lu]Lu-13 at 50°C suggested that rates of complex formation were time-dependent and the formation of (S)-[177Lu]Lu-13 was distinctly faster. The rates of complex formation for the corresponding 68Ga agents were comparable between structural isomers. The natGa and natLu equivalent showed high binding PSMA affinity (IC50 = 24-111 nM), comparable to that of the parent agent, [natGa]Ga-PSMA-093 (IC50 = 34.0 nM). Results of cell uptake and biodistribution studies in PSMA-expressing PC3-PIP tumor-bearing mice appeared to show no difference between the labeled (R)- and (S)-isomers. This is the first time that a pair of [68Ga/177Lu]-(R)- and (S)-DOTAGA isomers of PSMA agents were evaluated. Results of biol. studies between the isomers showed no noticeable difference; however, the distinctions on the rate of Lu complex formation should be considered in the development of new 177Lu-DOTAGA-based radionuclide therapy agents in the future. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Category: chlorides-buliding-blocks

On December 31, 2020, Li, Haolan; Yue, Liangliang; Wu, Ming; Wu, Fengshou published an article.Application of 4569-86-2 The title of the article was Self-assembly of methylene violet-conjugated perylene diimide with photodynamic/photothermal properties for DNA photocleavage and cancer treatment. And the article contained the following:

Near-IR (NIR) light-activated phototherapy, such as photothermal therapy (PTT) and photodynamic therapy (PDT), has gained considerable attention due to the advantages of high efficiency and minimally invasiveness. However, the development of a single component therapeutic agent with clear structure and mol. weight that achieve photodynamic/photothermal synergistic therapy is still challenging. Herein, we design and synthesize a new smart photosensitizer (PRX) by conjugation of perylene diimide (PDI) and methylene violet (RAX). The typical donor-acceptor (D-A) structure of RAX facilitates the red-shift of absorption to the near-IR (NIR) region. The amphiphilic PRX could self-assemble into monodispersed nanoparticles (PRX NPs) with enhanced and broadened absorption. Under a single 808 nm laser irradiation, PRX NPs could generate efficient reactive oxygen species (ROS) and heat simultaneously with the photothermal conversion efficiency as high as 59%. PRX NPs displays strong interaction with DNA and can damage plasmid DNA upon light irradiation The biocompatibility and high phototoxicity of PRX NPs against A549 cells are further confirmed through MTT assay. Therefore, the as-prepared PRX NPs could be served as a promising antitumor nanoagent through photothermal/photodynamic combination manner. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Application of 4569-86-2
