Lelieveldt, Lianne P. W. M. published the artcileVinylboronic acid-caged prodrug activation using click-to-release tetrazine ligation, Safety of Picolinonitrile, the main research area is vinylboronic acid cage prodrug click controlled release tetrazine ligation.

Bioorthogonal reactions can be performed selectively in the presence of any biol. functional group and are widely used to achieve site-selective chem. modifications of biomols. The click-to-release reaction is a bioorthogonal bond-cleavage variant that has gained much interest over the last few years. The bioorthogonal reaction between tetrazines and trans-cyclooctenes or vinyl ethers, for example, initiates the release of a small mol. immediately after the cycloaddition with tetrazines. Recently, our group reported that vinylboronic acids (VBAs) give exceptionally high reaction rates in the bioorthogonal inverse electron-demand Diels-Alder reaction with tetrazines that are substituted with boron-coordinating ligands. In the present study, we show that VBAs can be used in a click-to-release variant and demonstrate its bioorthogonality with a VBA-protected doxorubicin prodrug. We show that the cytotoxicity of doxorubicin is silenced by the attachment of the VBA, and activity can be largely restored upon the reaction with a tetrazine, inducing cell death.

Li, Xingshu published the artcileIn Vivo Albumin Traps Photosensitizer Monomers from Self-Assembled Phthalocyanine Nanovesicles: A Facile and Switchable Theranostic Approach, Computed Properties of 91-15-6, the main research area is albumin photosensitizer self assembly phthalocyanine nanovesicle switchable theranostic.

Albumin is a promising candidate as a biomarker for potential disease diagnostics and has been extensively used as a drug delivery carrier for decades. In these two directions, many albumin-detecting probes and exogenous albumin-based nanocomposite delivery systems have been developed. However, there are only a few cases demonstrating the specific interactions of exogenous probes with albumin in vivo, and nanocomposite delivery systems usually suffer from tedious fabrication processes and potential toxicity of the complexes. Herein, we demonstrate a facile “”one-for-all”” switchable nanotheranostic (NanoPcS) for both albumin detection and cancer treatment. In particular, the in vivo specific binding between albumin and PcS, arising from the disassembly of injected NanoPcS, is confirmed using an inducible transgenic mouse system. Fluorescence imaging and antitumor tests on different tumor models suggest that NanoPcS has superior tumor-targeting ability and the potential for time-modulated, activatable photodynamic therapy.

Zhuo, Liang published the artcileAerobic Visible-Light Induced Intermolecular S-N Bond Construction: Synthesis of 1,2,4-Thiadiazoles from Thioamides under Photosensitizer-Free Conditions, Product Details of C6H4N2, the main research area is thiadiazole preparation green chem; thioamide photochem desulfurization oxidative cyclization.

Aerobic visible-light induced intermol. S-N bond construction has been achieved without the addition of photosensitizer, metal, or base. With this strategy, 1,2,4-thiadiazoles I (R = Ph, 4-methoxyphenyl, thiophen-3-yl, etc.; R1 = 4-methoxyphenyl, 2,6-dimethylphenyl, thiophen-2-yl, etc.) can be obtained from thioamides R/R1C(S)NH2. Preliminary mechanistic investigation suggested that the excited state of thioamides undergoes a single-electron-transfer (SET) process to afford thioamidyl radicals, which can be further transformed into a 1,2,4-thiadiazole through desulfurization and oxidative cyclization. The reaction has good functional group tolerance and represents a green method for the construction of S-N bonds.

Zhang, Yaling published the artcileNovel 4-arylaminoquinazolines bearing N,N-diethyl(aminoethyl)amino moiety with antitumor activity as EGFRwt-TK inhibitor, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is arylaminoquinazoline synthesis antcancer EGFR apoptosis cell cycle cancer; -diethyl(aminoethyl)amino moiety; Quinazoline derivatives; antiproliferative activities; molecular docking; wild type epidermal growth factor receptor tyrosine kinase (EGFR-TK).

Herein, four novel 4-arylaminoquinazoline derivatives with N,N-diethyl(aminoethyl)amino moiety were designed, synthesized and evaluated on biol. activities in vitro. All synthesized compounds have inhibitory effects against tumor cells (SW480, A549, A431 and NCI-H1975). In particular, 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(5-((N,N-diethyl(aminoethyl))aminomethyl)furan-2-yl)quinazoline () and 6-(5-((N,N-diethylethyl)aminomethyl)furan-2-yl)-4-(4-(E)-(propen-1-yl)phenylamino)quinazoline () were potent antitumor agents which showed high antiproliferative activities against tumor cells in vitro. Moreover, compound could induce late apoptosis of A549 cells at high concentrations and arrest cell cycle of A549 cells in the G0/G1 phase at tested concentrations Also, compound could inhibit the activity of wild type epidermal growth factor receptor tyrosine kinase (EGFRwt-TK) with IC50 value of 15.60 nM. Mol. docking showed that compound formed three hydrogen bonds with EGFRwt-TK, while lapatinib formed only two hydrogen bonds with the receptor protein. It is believed that this work would be giving a reference for developing anti-cancer drugs targeted EGFR-TK.

Lauria, Antonino published the artcileAnnelated pyrrolo-pyrimidines from amino-cyanopyrroles and BMMAs as leads for new DNA-interactive ring systems, Safety of 2-Amino-4-methyl-1H-pyrrole-3-carbonitrile, the main research area is sulfanylmethyleneamino ester aminocyanopyrrole heterocyclization; pyrrolopyrimidine preparation anticancer; imidazopyrrolopyrimidine preparation anticancer.

The efficient one-pot synthesis of several tricyclic systems, e.g., I, obtained from the reaction of substituted 2-amino-3-cyanopyrroles and 3-amino-4-cyanopyrroles with BMMAs, is reported. The duration and yields of the reaction strongly depend on the reactivity of the starting pyrrole and on the size of the ring to be formed. Mechanist features of the reaction were investigated and proposed by studying also the reactivity of a 3-aminopyrrole-2,4-dicyano substituted. The method reported represents an example of the use of BMMA reagents in combination with pyrrole derivatives and allowed an easy and versatile entry to a large number of pyrrolo-pyrimidines further annelated with nitrogen heterocycles of different sizes. These polycondensed heterocycles possessed the requisite to interact with DNA.

Boutard, Nicolas published the artcileDiscovery and structure-activity relationships of N-aryl 6-aminoquinoxalines as potent PFKFB3 kinase inhibitors, Application In Synthesis of 1885-29-6, the main research area is crystal structure neoplasm antitumor PFKFB3 kinase inhibitor aminoquinoxaline; cancer; enzymes; glycolysis; inhibitors; metabolism.

Energy and biomass production in cancer cells are largely supported by aerobic glycolysis in what is called the Warburg effect. The process is regulated by key enzymes, among which phosphofructokinase PFK-2 plays a significant role by producing fructose-2,6-biphosphate; the most potent activator of the glycolysis rate-limiting step performed by phosphofructokinase PFK-1. Herein, the synthesis, biol. evaluation and structure-activity relationship of novel inhibitors of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3), which is the ubiquitous and hypoxia-induced isoform of PFK-2, are reported. X-ray crystallog. and docking were instrumental in the design and optimization of a series of N-aryl 6-aminoquinoxalines. The most potent representative, N-(4-methanesulfonylpyridin-3-yl)-8-(3-methyl-1-benzothiophen-5-yl)quinoxalin-6-amine, displayed an IC50 of 14 nM for the target and an IC50 of 0.49 μM for fructose-2,6-biphosphate production in human colon carcinoma HCT116 cells. This work provides a new entry in the field of PFKFB3 inhibitors with potential for development in oncol.

Li, Zhanhui published the artcileDesign, synthesis, and evaluation of pyrrolidine based CXCR4 antagonists with in vivo anti-tumor metastatic activity, COA of Formula: C6H4N2, the main research area is pyrrolidine preparation antitumor metastatic activity lipophilicity antagonist; Antagonist; CXCL12; CXCR4; Chemokine; GPCR.

The design, synthesis and evaluation of novel CXCR4 antagonists were based on a pyrrolidine scaffold e.g., 3-(1,3-dioxolan-2-yl)-1-(3-methylpyridin-2-yl)propan-1one. The structural exploration/optimization identified numerous potent CXCR4 antagonists, represented by (S)-2-methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine, which displayed potent binding affinity to CXCR4 receptor (IC50 = 79 nM competitively displacing fluorescent 12G5 antibody) and inhibited CXCL12 induced cytosolic calcium flux (IC50 = 0.25 nM). Moreover, in a transwell invasion assay, (S)-2-methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine significantly mitigated CXCL12/CXCR4 mediated cell migration. The (S)-2-Methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine exhibited good physicochem. properties (MW 367, logD7.4 1.12, pKa 8.2) and excellent in vitro safety profiles (e.g., hERG patch clamp IC50 > 30μM and minimal CYP isoenzyme inhibition). Importantly, (S)-2-methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine displayed much improved metabolic stability in human and rat liver microsomes. Lastly, (S)-2-Methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine demonstrated marked efficacy in a cancer metastasis model in mice. These results strongly support (S)-2-methyl-4-(4-methylpiperazin-1-yl)-6-((2-(3methylpyridin-2-yl)pyrrolidin-1-yl)methyl)pyrimidine as a prototypical lead for the development of promising CXCR4 antagonists as clin. candidates.

Ertas, Merve published the artcilePotent ribonucleotide reductase inhibitors: Thiazole-containing thiosemicarbazone derivatives, HPLC of Formula: 100-70-9, the main research area is antitumor agents ribonucleotide reductase inhibitors thiazole thiosemicarbazone ADME; antitumor agents; ribonucleotide reductase; thiazole; thiosemicarbazone.

The antioxidant, antimalarial, antibacterial, and antitumor activities of thiosemicarbazones have made this class of compounds important for medicinal chemists. In addition, thiosemicarbazones are among the most potent and well-known ribonucleotide reductase inhibitors. In this study, 24 new thiosemicarbazone derivatives were synthesized, and the structures and purity of the compounds were determined by IR, 1H NMR, 13C NMR, mass spectroscopy, and elemental anal. The IC50 values of these 24 compounds were determined with an assay for ribonucleotide reductase inhibition. Compounds 19, 20, and 24 inhibited ribonucleotide reductase enzyme activity at a higher level than metisazone as standard The cytotoxic effects of these compounds were measured on the MCF7 (human breast adenocarcinoma) and HEK293 (human embryonic kidney) cell lines. Similarly, compounds 19, 20, and 24 had a selective effect on the MCF7 and HEK293 cell lines, killing more cancer cells than cisplatin as standard The compounds (especially 19, 20, and 24 as the most active ones) were then subjected to docking experiments to identify the probable interactions between the ligands and the enzyme active site. The complex formation was shown qual. The ADME (absorption, distribution, metabolism, and excretion) properties of the compounds were analyzed using in-silico techniques.

Zhao, Xuan published the artcileA monoamine oxidase-A inhibitor phthalocyanine conjugate for targeted photodynamic therapy and inhibition of prostate cancer metastasis in vitro, Recommanded Product: Phthalonitrile, the main research area is preparation MAOA inhibitor phthalocyanine conjugate prostate cancer metastasis PDT.

Photodynamic therapy (PDT), as an alternative non-invasive clin. treatment modality, has been extensively employed for various anticancer applications in preclin. and clin. trials. However, there is hardly any PDT research based on invasive or metastatic tumors. But it can′t be ignored that cancer metastases are responsible for 90% of all cancer-related death. Among these metastatic cancers, prostate cancer (PCa) is regarded as one of the leading causes of cancer related deaths amongst male patients due to its high metastasis and high fatality rate. At present, it remains a great challenge to apply traditional PDT technol. for inhibiting prostate cancer metastasis. In this work, we successfully designed and synthesized a novel MAO-A targeted photosensitizer Pc-MLB for targeted photodynamic treatment of prostate cancer and inhibiting its metastasis in vitro. In vitro experiments demonstrate that Pc-MLB shows high target affinity and specificity towards prostate cancer cells and remarkable photodynamic anticancer activity compared with the control. More significantly, the migration and invasion assays show that Pc-MLB exhibits the ability to inhibit the migration and metastasis of prostate cancer cells to some extent.
