Synthesis, and evaluation of in vitro and in vivo anticancer activity of 14-substituted oridonin analogs: A novel and potent cell cycle arrest and apoptosis inducer through the p53-MDM2 pathway

A series of novel oridonin derivatives bearing various substituents on the 14-OH position were designed and synthesised. Their antitumour activity was evaluated in vitro against three human cancer cell lines (HCT116, BEL7402, and MCF7). Most tested derivatives showed improved anti-proliferative activity compared to the lead compound oridonin and the positive control drug 5-fluorouracil (5-Fu). Among them, compound C7 (IC50 = 0.16 muM) exhibited the most potent anti-proliferative activity against HCT116 cells; it was about 43- and 155-fold more efficacious than that of oridonin (IC50 = 6.84 muM) and 5-Fu (IC50 = 24.80 muM) in HCT116 cancer cells. Interestingly, the IC50 value of compound C7 in L02 normal cells was 23.6-fold higher than that in HCT116 cells; it exhibited better selective anti-proliferative activity and specificity than oridonin and 5-Fu. Furthermore, compound C7 possibly induced cell cycle arrest and apoptosis by regulating the p53-MDM2 signalling pathway. Notably, C7 displayed more significant suppression of tumour growth than oridonin in colon tumour xenograft models where the tumour growth inhibition rate was 85.82%. Therefore, compound C7 could be a potential lead compound for the development of a novel antitumour agent.

In the latter complex, the corresponding bond lengths for Ni-O (water). Ni-O(carboxylate) and Ni-N are 2.127 (2). 2.036 (2) and 2.039 (3) A. respectively. Both crystals are stabilized by similar stacking interactions of the ligand, and also by hydrogen bonds between the hydrate and coordinated water molecules.

N-heterocyclic carbene catalyzed enantioselective [3 + 2] dearomatizing annulation of saturated carboxylic esters with n-iminoisoquinolinium ylides

The dearomatizing annulation reaction is a significant challenge in organic chemistry. The direct activation of alpha-carbons of simple saturated esters, as nucleophiles, is an important synthesis strategy. In the present study, we disclose [3 + 2] dearomatizing annulation reactions with direct activating alpha-carbons of saturated carboxylic esters and N-iminoisoquinolinium ylides, which possess highly enantioselective characteristics, catalyzed by N-heterocyclic carbenes (NHCs). The protocol achieves isoquinoline dearomatization and the construction of tricyclic chiral products under mild conditions with good yield, substrate tolerance, and diastereoselectivity as well as excellent enantioselectivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 5-Chloroisoquinoline, you can also check out more blogs about5430-45-5

Pd-containing organopolyoxometalates derived from Dawson polyoxometalate [P2W15V3O62]9-: Lewis acidity and dual site catalysis

Grafting of a palladium complex to the Dawson vanadotungstate polyanion [P2W15V3O62]9- via an organic ligand generates a large family of pincer-type hybrid polyoxometalates. The palladium-POM derivatives have dual catalytic properties. Unlike their parent inorganic polyanions, they catalyze allylations while retaining their oxidant character, which leads to single-pot dual site catalysis. This opens a new route for multicatalytic reactions.

Iron(II)-Based Metalloradical Activation: Switch from Traditional Click Chemistry to Denitrogenative Annulation

A unique concept for the intermolecular denitrogenative annulation of 1,2,3,4-tetrazoles and alkynes was discovered by using a catalytic amount of Fe(TPP)Cl and Zn dust. The reaction precludes the traditional, more favored click reaction between an organic azide and alkynes, and instead proceeds by an unprecedented metalloradical activation. The method is anticipated to advance access to the construction of important basic nitrogen heterocycles, which will in turn enable discoveries of new drug candidates.

Integrating Hydrogen Production with Aqueous Selective Semi-Dehydrogenation of Tetrahydroisoquinolines over a Ni2P Bifunctional Electrode

Exploring an alternative anodic reaction to produce value-added chemicals with high selectivity, especially integrated with promoted hydrogen generation, is desirable. Herein, a selective semi-dehydrogenation of tetrahydroisoquinolines (THIQs) is demonstrated to replace the oxygen evolution reaction (OER) for boosting H2 evolution reaction (HER) in water over a Ni2P nanosheet electrode. The value-added semi-dehydrogenation products, dihydroisoquinolines (DHIQs), can be selectively obtained with high yields at the anode. The controllable semi-dehydrogenation is attributed to the in situ formed NiII/NiIII redox active species. Such a strategy can deliver a variety of DHIQs bearing electron-withdrawing/donating groups in good yields and excellent selectivities, and can be applied to gram-scale synthesis. A two-electrode Ni2P bifunctional electrolyzer can produce both H2 and DHIQs with robust stability and high Faradaic efficiencies at a much lower cell voltage than that of overall water splitting.

Metal-Free Oxidative B?N Coupling of nido-Carborane with N-Heterocycles

A general method for the oxidative substitution of nido-carborane (7,8-C2B9H12?) with N-heterocycles has been developed by using 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) as an oxidant. This metal-free B?N coupling strategy, in both inter- and intramolecular fashions, gave rise to a wide array of charge-compensated, boron-substituted nido-carboranes in high yields (up to 97 %) with excellent functional-group tolerance under mild reaction conditions. The reaction mechanism was investigated by density-functional theory (DFT) calculations. A successive single-electron transfer (SET), B?H hydrogen-atom transfer (HAT), and nucleophilic attack pathway is proposed. This method provides a new approach to nitrogen-containing carboranes with potential applications in medicine and materials.
