The cross-coupling of sodium (hetero)aryl carboxylates with (hetero)aryl chlorides proceeds with 1 mol % palladium catalyst and does not require inorganic base, silver salts, or copper salts. This coupling uses two low energy partners, and the only stoichiometric byproducts are carbon dioxide and sodium chloride. The substrate scope includes less activated aryl chlorides and carboxylates (>25 examples). The palladium loading could be reduced to 0.1 mol %, and Buchwald-style precatalysts could be used.

Understanding the nature of interactions between the aromatic organic pollutants with dissolved humic acid (HA) is fundamental for the prediction of their environmental fate and subsequent development of efficient remediation methods. The present study employs solution-state H-1/F-19 NMR methods to investigate the non-covalent interaction between aqueous peat humic acid (Aldrich HA) and monoaromatic carboxylic acids (CA), viz., 2, 6 diflourobenzoic acid (DFBA) and its non-fluorinated analog, benzoic acid (BA). NMR self-diffusion measurement of HA protons confirmed micellar nature indicating possibility of encapsulation of small molecules through host-guest interaction. F-19-H-1 and H-1-H-1 saturation transfer difference (STD) experiments reveal the mode of insertion of CA into HA superstructure. The strength of interaction has been evaluated by analyzing T-1/T-2 relaxation times and self-diffusion coefficients of CA as a function of HA concentration. Association constants extracted for CA-HA complexes from NMR diffusion experiments reflected that the association between DFBA-HA (2.34 mM(-1)) is significantly higher than that of BA-HA (0.97 mM(-1)). The experimental outcome reiterated that substitution of -H with halogen atoms (-F in specific) to aromatic ring plays a dominant role in modulating the strength of association and mode of insertion of organic pollutants into HA superstructure. The present study emphasizes that AHA can be a potential remediating agent for organic contaminants due to its superior binding affinity compared to less humified extracted HA (EHA) from Karwar, Rajasthan, India.

Tankyrases 1 and 2 are central biotargets in the WNT/beta-catenin signaling and Hippo signaling pathways. We have previously developed tankyrase inhibitors bearing a 1,2,4-triazole moiety and binding predominantly to the adenosine binding site of the tankyrase catalytic domain. Here we describe a systematic structure-guided lead optimization approach of these tankyrase inhibitors. The central 1,2,4-triazole template and trans-cyclobutyl linker of the lead compound 1 were left unchanged, while side-group East, West, and South moieties were altered by introducing different building blocks defined as point mutations. The systematic study provided a novel series of compounds reaching picomolar IC50 inhibition in WNT/beta-catenin signaling cellular reporter assay. The novel optimized lead 13 resolves previous atropisomerism, solubility, and Caco-2 efflux liabilities. 13 shows a favorable ADME profile, including improved Caco-2 permeability and oral bioavailability in mice, and exhibits antiproliferative efficacy in the colon cancer cell line COLO 320DM in vitro.

BACKGROUND: Chemical pesticides are the main measures for pest control, but have caused growing resistance of pests and brought a series of environmental problems. Development of high-efficient insecticidal molecules with novel scaffolds is therefore particularly urgent. RESULTS: Based on a [5 + 1] annulation reaction with 5-amino-1H-phenylpyrazole and dialkyl bromomalonate, 27 novel five-substituted 4,5-dihydropyrazolo[1,5-a]quinazolines were designed following the intermediate derivatization method and synthesized. Bioassay results indicated that most of the test compounds displayed good insecticidal activities against Plutella xylostella, Spodoptera frugiperda, and Solenopsis invicta. In particular, the insecticidal activities of compounds 4a, 4f, and 4m against P. xylostella [median lethal concentration (LC50) values ranged from 3.87 to 5.10 mg L-1] were comparable to that of indoxacarb (LC50 = 4.82 mg L-1). In addition, compounds 4a and 9e showed similar high insecticidal activities against Spodoptera frugiperda (mortality rate = 79.63% and 72.12%) at 100 mg L-1, comparable to that of fipronil (mortality rate: 68.44%); compound 9a showed possible delayed toxicity against Solenopsis invicta (mortality rate: 95.66%) after 5 days of treatment at 1.0 mg L-1. CONCLUSION: Due to their high insecticidal activities against P. xylostella, compound 4m, 4a, and 4f could be considered as qualified candidates for novel insecticide. Several other 4,5-dihydropyrazolo[1,5-a]quinazolines with relatively high bioactivity, such as compounds 9a and 9e, are also worth further optimization as potential insecticide or anticide candidates.

Transition-metal-catalyzed sp(2) C-N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp(3) C-N formation reactions have been reported occasionally, and methods that can realize both sp(2) and sp(3) C-N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C-N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)(2) as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N-2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful alpha-chiral alkyl amines, and rapid construction of different ureas and primary amines.

A new series of 2,4-disubstituted-2-thiopyrimidines 6a-t, 9a, and 9b was efficiently designed and synthesized as antiangiogenic and cytotoxic agents. Compounds 6j, 6l, and 6d showed IC50 values of 1.23, 3.78, and 3.84 mu M, respectively, against the vascular endothelial growth factor receptor-2 (VEGFR-2). Most of the synthesized 2-thiouracils showed antiproliferative activity against the HepG2 cell line (hepatocellular carcinoma) in the micromolar range, for instance, 9b, 6l, 6m, 6n, and 6j displayed IC50 = 7.92, 8.35, 8.51, 9.59, and 13.06 mu M, respectively, relative to sorafenib (III; IC50 = 10.99 mu M). Also, compounds 6j, 9a, 6m, and 6s (IC50 = 15.21, 16.96, 17.68, and 18.15 mu M, respectively) are the most potent compounds against the UO-31 cell line. Further evaluation of the effect of the synthesized candidates on VEGFR-2 in the HepG2 cell line demonstrated that compounds 6j and 6l exhibit VEGFR-2 inhibitory activity of 87% and 84%, respectively, relative to sorafenib (III; 92%). In silico docking of the synthesized hits into the binding site of VEGFR-2 showed their ability to perform the main binding interactions with the key amino acids in the binding site. Studying the in silico predicted ADME (absorption, distribution, metabolism, and excretion) parameters for the synthesized thiouracils demonstrated that they have favorable pharmacokinetic and drug-likeness properties. These results demonstrate that the 2,4-disubstituted thiouracils 6 and 9 have not only favorable antiangiogenic and antiproliferative activity but also satisfy the criteria required for the development of orally bioavailable drugs. Consequently, they represent a biologically active scaffold that should be further optimized for future discovery of potential hits.

Effective treatment of tuberculosis is challenged by the rapid development of Mycobacterium tuberculosis (Mtb) multidrug resistance that presumably could be overcome with novel multi-target drugs. Aminoacyl-tRNA synthetases (AARSs) are an essential part of protein biosynthesis machinery and attractive targets for drug discovery. Here, we experimentally verify a hypothesis of simultaneous targeting of structurally related AARSs by a single inhibitor. We previously identified a new class of mycobacterial leucyl-tRNA synthetase inhibitors, N-benzylidene-N ‘-thiazol-2-yl-hydrazines. Molecular docking of a library of novel N-benzylidene-N ‘-thiazol-2-yl-hydrazine derivatives into active sites of M. tuberculosis LeuRS (MtbLeuRS) and MetRS (MtbMetRS) resulted in a panel of the best ranking compounds, which were then evaluated for enzymatic potency. Screening data revealed 11 compounds active against MtbLeuRS and 28 compounds active against MtbMetRS. The hit compounds display dual inhibitory potency as demonstrated by IC50 values for both enzymes. Compound 3 is active against Mtb H37Rv cells in in vitro bioassays.
