Two new flavonoid glycosides, 2 ‘,4 ‘-dihydroxydihydrochalcone-4-O-beta-d-glucopyranoside (1) and medicarpin-3-O-beta-d-apiofuranosyl (1 -> 2)-beta-d-glucopyranoside (2), together with 34 known flavonoids were isolated from the 75% EtOH extract of the dried roots of Glycyrrhiza uralensis Fisch. Their structures were elucidated on the basis of spectroscopic analyses. The flavonoids were classified into ten sub-types, namely, dihydrochalcone (1), pterocarpans (2-4), flavones (5-6), flavanones (7-11), chalcones (12-15), retro-chalcones (16-18), isoflavans (19-21), isoflavones (22-28), 3-arylcoumarins (29-30), and coumestans (31-36). The isolated flavonoids were evaluated for in vitro hepatoprotective activity against d-galactosamine-induced toxicity in human hepatoma HepG2 cells.

To develop novel simultaneous inhibition of PLK1 and BRD4 bromodomain by a single molecule, three series of novel pteridinone derivatives were designed, synthesized and evaluated for their biological activity. Most compounds exhibited moderate to excellent cytotoxic activity against A549, HCT116, PC-3 and MCF-7 cell lines. The most promising compoundIII(4)showed high antiproliferative effects on four cell lines with IC(50)values of 1.27 mu M, 1.36 mu M, 3.85 mu M and 4.06 mu M, respectively. The enzymatic assay identifiedIII(4)as a potent PLK1 and BRD4 dual inhibitor with % inhibition values of 96.6 and 59.1, respectively. Furthermore, to clarify the anticancer mechanism of the target compounds, explorations in the bioactivity were conducted. The results showed that compoundIII(4)obviously inhibited the proliferation of HCT-116 cell lines, induced a great decrease in the mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested the S phase of HCT116 cells.

Heteroarylation of alkenes with aryl iodides was efficiently achieved with a (MeDalphos)AuCl complex through Au-I/Au-III catalysis. The possibility to combine oxidative addition of aryl iodides and yr-activation of alkenes at gold is demonstrated for the first time. The reaction is robust and general (> 30 examples including internal alkenes, 5-, 6-, and 7-membered rings). It is regioselective and leads exclusively to trans addition products. The (P,N) gold complex is most efficient with electron-rich aryl substrates, which are troublesome with alternative photoredox/oxidative approaches. In addition, it provides a very unusual switch in regioselectivity from 5-exo to 6-endo cyclization between the Z and E isomers of internal alkenols.

Aziridines are ubiquitous in bioactive molecules and often serve as key synthetic building blocks. We report herein an intramolecular KI/TBHP mediated oxidative dehydrogenative C(sp(3))-H amination reaction to synthesize a diverse array of trans-2,3-disubstituted aziridines in good yields under mild conditions. The synthetic utility of this protocol was further highlighted by a one-pot, two-step synthesis of unprotected aziridines.

Olefin aminations are important synthetic technologies for the construction of aliphatic C-N bonds. Here we report a catalytic protocol for olefin hydroamidation that proceeds through transient amidyl radical intermediates that are formed via proton-coupled electron transfer (PCET) activation of the strong N-H bonds in N-alkyl amides by an excited-state iridium photocatalyst and a dialkyl phosphate base. This method exhibits a broad substrate scope, high functional group tolerance, and amenability to use in cascade polycyclization reactions. The feasibility of this PCET protocol in enabling the intermolecular anti-Markovnikov hydroamidation reactions of unactivated olefins is also demonstrated.

A series of novel chalcone derivatives containing a thiophene sulfonate group were designed and synthesized. The structures of all title compounds were determined by H-1-NMR, C-13-NMR and HRMS. Antibacterial bioassays indicated that, compound 2l demonstrated excellent antibacterial activities against Xanthomonas axonopodis pv. citri (Xac), with an EC50 value of 11.4 mu g mL(-1), which is significantly superior to those of bismerthiazol (BT) (51.6 mu g mL(-1)) and thiodiazole-copper (TC) (94.7 mu g mL(-1)). Meanwhile, the mechanism of action of compound 2l was confirmed by using scanning electron microscopy (SEM). In addition, compound 2e showed remarkable inactivation activity against Tobacco mosaic virus (TMV), with an EC50 value of 44.3 mu g mL(-1), which was superior to that of ningnanmycin (120.6 mu g mL(-1)). Microscale thermophoresis (MST) also showed that the binding of compounds 2e and 2h to Tobacco mosaic virus coat protein (TMV-CP) yielded K-d values of 0.270 and 0.301 mu mol L-1, which are better than that of ningnanmycin (0.596 mu mol L-1). At the same time, molecular docking studies for 2e and 2h with TMV-CP (PDB code: ; 1EI7) showed that the compound was embedded well in the pocket between the two subunits of TMV-CP in each case. These results suggested that chalcone derivatives containing a thiophene sulfonate group may be considered as activators in the design of antibacterial and antiviral agents.

A complementing Pd- and Rh-catalyzed dynamic kinetic resolution (DKR) of racemic allenes leading to N-allylated pyrazoles is described. Such compounds are of enormous interest in medicinal chemistry as certified drugs and potential drug candidates. The new methods feature high chemo-, regio- and enantioselectivities aside from displaying a broad substrate scope and functional group compatibility. A mechanistic rational accounting for allene racemization and trans-alkene selectivity is discussed.

Ketones are of great importance in synthesis, biology, and pharmaceuticals. This paper reports an iridium complexes-catalyzed cross-coupling of alcohols via hydrogen borrowing, affording a series of alpha-alkylated ketones in high yield (86 %-95 %) and chemoselectivities (>99 : 1). This methodology has the advantages of low catalyst loading (0.1 mol%) and environmentally benign water as the solvent. Studies have shown the amount of base has a great impact on chemoselectivities. Meanwhile, deuteration experiments show water plays an important role in accelerating the reduction of the unsaturated ketones intermediates. Remarkably, a gram-scale experiment demonstrates this methodology of iridium-catalyzed cross-coupling of alcohols has potential application in the practical synthesis of alpha-alkylated ketones.
