Abstract
Ectonucleotidases inhibitors (ENPPs, e5'NT (CD73) and h-TNAP) are potential therapeutic candidates for the treatment of cancer. Adenosine, the cancer-developing, and growth moiety is the resultant product of these enzymes. The synthesis of small molecules that can increase the acidic and ionizable structure of adenosine 5-monophosphate (AMP) has been used in traditional attempts to inhibit ENPPs, ecto-5'-nucleotidase and h-TNAP. In this article, we present a short and interesting method for developing substituted indole acetic acid sulfonate derivatives (5a-5o), which are non-nucleotide based small molecules, and investigated their inhibitory potential against recombinant h-ENPP1, h-ENPP3, h-TNAP, h-e5'NT and r-e5'NT. Their overexpression in the tumor environment leads to high adenosine level that results in tumor development as well as immune evasion. Therefore, selective, and potent inhibitors of these enzymes would be expected to decrease adenosine levels and manage tumor development and progression. Our intended outcome led to the discovery of new potent inhibitors like' 5e (IC50 against h-ENPP1 = 0.32 ± 0.01 μM, 58 folds increased with respect to suramin), 5j (IC50 against h-ENPP3 = 0.62 ± 0.003 μM, 21 folds increase with respect to suramin), 5c (IC50 against h-e5'NT = 0.37 ± 0.03 μM, 115 folds increase with respect to sulfamic acid), 5i (IC50 against r-e5'NT = 0.81 ± 0.05 μM, 95 folds increase with respect to sulfamic acid), and 5g (IC50 against h-TNAP = 0.59 ± 0.08 μM, 36 folds increase with respect to Levamisole). Molecular docking studies revealed that inhibitors of these selected target enzymes induced favorable interactions with the key amino acids of the active site, including Lys255, Lys278, Asn277, Gly533, Lys528, Tyr451, Phe257, Tyr340, Gln465, Gln434, Lys437, Glu830, Cys818, Asn499, Arg40, Phe417, Phe500, Asn503, Asn599, Tyr281, Arg397, Asp526, Phe419 and Tyr502. Enzyme kinetic studies revealed that potent compounds such as 5j and 5e blocked these ectonucleotidases competitively while compounds 5e and 5c presented an un-competitive binding mode. 5g revealed a non-competitive mode of inhibition.

Abstract
Eight new 4-substituted 1-amino-9,10-anthraquinones containing a primary amino group were synthesized by nucleophilic substitution of bromine in 1-amino-4-bromo-9,10-anthraquinones. 1-Amino-4-[2-(hydroxyethyl)amino]-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid containing a biogenic amine fragment (2-aminoethanol) was converted into the corresponding 1-triazenyl derivatives. The structure of the synthesized compounds was determined on the basis of the LC/MS and 13C and 1H NMR data, and their drug likeness was estimated in silico. Compounds with a good drug likeness score were analyzed by DIGEP-Pred, their possible interactions with proteins were simulated using STRING, and their biological activity was interpreted using the Kyoto Encyclopedia of Genes and Genomes.

Abstract
Cross-coupling reactions furnishing carbon–carbon (C–C) and carbon–heteroatom (C–X) bond is one of the most challenging tasks in organic syntheses. The early developed reaction protocols by Ullmann, Ullman–Goldberg, Cadiot–Chodkiewicz, Castro–Stephens, and Corey–House, utilizing elemental copper or its salts as catalyst have, for decades, attracted and inspired scientists. However, these reactions were suffering from the range of functional groups tolerated as well as severely restricted by the harsh reaction conditions often required high temperatures (150–200 °C) for extended reaction time. Enormous efforts have been paid to develop and achieve more sustainable reaction conditions by applying the microwave irradiation. The use of controlled microwave heating dramatically reduces the time required and therefore resulting in increase in the yield as well as the efficiency of the reaction. This review is mainly focuses on the recent advances and applications of copper catalyzed cross-coupling generation of carbon–carbon and carbon–heteroatom bond under microwave technology.

Development of Anthraquinone Derivatives as Ectonucleoside Triphosphate Diphosphohydrolase (NTPDase) Inhibitors With Selectivity for NTPDase2 and NTPDase3. Front Pharmacol 2020; 11:1282.

Abstract
Ectonucleoside triphosphate diphosphohydrolases (NTPDases) catalyze the hydrolysis of nucleoside tri- and di-phosphates to mono-phosphates. The products are subsequently hydrolyzed by ecto-5′-nucleotidase (ecto-5′-NT) to nucleosides. NTPDase inhibitors have potential as novel drugs, e.g., for the treatment of inflammation, neurodegenerative diseases, and cancer. In this context, a series of anthraquinone derivatives structurally related to the anthraquinone dye reactive blue-2 (RB-2) was synthesized and evaluated as inhibitors of human NTPDases utilizing a malachite green assay. We identified several potent and selective inhibitors of human NTPDase2 and -3. Among the most potent NTPDase2 inhibitors were 1-amino-4-(9-phenanthrylamino)-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (20, PSB-16131, IC50 of 539 nM) and 1-amino-4-(3-chloro-4-phenylsulfanyl)phenylamino-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (48, PSB-2020, IC50 of 551 nM). The most potent NTPDase3 inhibitors were 1-amino-4-[3-(4,6-dichlorotriazin-2-ylamino)-4-sulfophenylamino]-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (42, PSB-1011, IC50 of 390 nM) and 1-amino-4-(3-carboxy-4-hydroxyphenylamino)-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (33, PSB-2046, IC50 of 723 nM). The best NTPDase2 inhibitor 20 showed a non-competitive inhibition type, while the NTPDase3 inhibitor 42 behaved as a mixed-type inhibitor. These potent compounds were found to be selective vs. other NTPDases. They will be useful tools for studying the roles of NTPDase2 and -3 in physiology and under pathological conditions.

Abstract
Ecto-nucleoside triphosphate diphosphohydrolase1 (NTPDase1, CD39) is a major ectonucleotidase that hydrolyzes proinflammatory ATP via ADP to AMP, which is subsequently converted by ecto-5'-nucleotidase (CD73) to immunosuppressive adenosine. Activation of CD39 has potential for treating inflammatory diseases, while inhibition was suggested as a novel strategy for the immunotherapy of cancer. In the present study, we developed a selective and highly sensitive capillary electrophoresis (CE) assay using a novel fluorescent CD39 substrate, a fluorescein-labelled ATP (PSB-170621A) that is converted to its AMP derivative. To accelerate the assays, a two-directional (forward and reverse) CE system was implemented using 96-well plates, which is suitable for the screening of compound libraries (Z'-factor: 0.7). The detection limits for the forward and reverse operation were 11.7 and 2.00 pM, respectively, indicating a large enhancement in sensitivity as compared to previous methods (e.g. malachite-green assay: 1 000 000-fold, CE-UV assay: 500 000-fold, fluorescence polarization immunoassay: 12 500-fold). Enzyme kinetic studies at human CD39 revealed a Km value of 19.6 μM, and a kcat value of 119 × 10-3 s-1 for PSB-170621A, which shows similar substrate properties as ATP (11.4 μM and 82.5 × 10-3 s-1). The compound displayed similar properties at rat and mouse CD39. Subsequent docking studies into a homology model of human CD39 revealed a hydrophobic pocket that accommodates the fluorescein tag. PSB-170621A was found to be preferably hydrolyzed by CD39 as compared to other ectonucleotidases. The new assay was validated by performing inhibition assays with several standard CD39 inhibitors yielding results that were consonant with data using the natural substrates.

Abstract
The P2Y12 receptor is one of eight known P2Y receptor subtypes, and belongs to the G-protein-coupled receptor (GPCR) family. The P2Y12 receptor is highly expressed on blood platelets and in the brain. Potent, selective, peripherally acting antagonists for the P2Y12 receptor are used clinically as antithrombotic drugs. Several different scaffolds have been identified as P2Y12 receptor antagonists, including irreversibly acting thienotetrahydropyridines (prodrugs), and reversible competitive antagonists, including adenine nucleotide analogs, piperazinyl-glutamate-quinolines, -pyridines, and -pyrimidines, and anthraquinone derivatives. Here, we provide an overview of the different scaffolds that have been developed as P2Y12 receptor antagonists, some of which have become important therapeutics.

Abstract
P2Y4 is a Gq protein-coupled receptor activated by uridine-5'-triphosphate (UTP), which is widely expressed in the body, e.g., in intestine, heart, and brain. No selective P2Y4 receptor antagonist has been described so far. Therefore, we developed and optimized P2Y4 receptor antagonists based on an anthraquinone scaffold. Potency was assessed by a fluorescence-based assay measuring inhibition of UTP-induced intracellular calcium release in 1321N1 astrocytoma cells stably transfected with the human P2Y4 receptor. The most potent compound of the present series, sodium 1-amino-4-[4-(2,4-dimethylphenylthio)phenylamino]-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate (PSB-16133, 61) exhibited an IC50 value of 233 nM, selectivity versus other P2Y receptor subtypes, and is thought to act as an allosteric antagonist. A receptor homology model was built and docking studies were performed to analyze ligand-receptor interactions. Compound 64 (PSB-1699, sodium 1-amino-4-[4-(3-pyridin-3-ylmethylthio)phenylamino]-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate) represents the most selective P2Y4 receptor antagonist known to date. Compounds 61 and 64 are therefore anticipated to become useful tools for studying this scarcely investigated receptor.
