Metal-Free Chemoselective Oxidative Dehomologation or Direct Oxidation of Alcohols: Implication for Biomass Conversion

A transition metal-free, chemoselective reaction was performed using the sodium tert-butoxide-oxygen (NaOtBu-O2) system, resulting in either oxidative dehomologation or direct oxidation of alcohols. In particular, the newly developed protocol may be used to predict the major product formed, which depends on alkyl chain length of the alcohols and reaction conditions. The rational mechanism of this transformation was also demonstrated by performing an 18O isotopic labelling experiment. This protocol presents a straightforward method for biomass conversion of a lignin model compound to phenol and benzoic acid.

Understanding the exceptional hydrogen-atom donor characteristics of water in TiIII-mediated free-radical chemistry

In recent years solid evidence of HAT reactions involving water as hydrogen atom source have been presented. In this work we demonstrate that the efficiency of titanocene(III) aqua complexes as an unique class of HAT reagents is based on two key features: (a) excellent binding capabilities of water toward titanocene(III) complexes and (b) a low activation energy for the HAT step. The theory has predictive capabilities fitting well with the experimental results and may aid to find more examples of this remarkable radical reaction.

Green Synthesis and Antimicrobial Activity of Some Novel N-Arylimidazo[1,2-a]pyrazine-2-Carboxamide Derivatives

The article deals with the synthesis of some novel N-arylimidazo[1,2-a]pyrazine-2-carboxamides (7a-l) by condensation reaction of imidazo[1,2-a]pyrazine-2-carboxylic acid (5) with different aliphatic/aromatic amines (6a-l) by using 1-methylimidazole, Mukaiyama?s reagent and 2-chloro-1-methylpyridinium iodide under microwave irradiation conditions. A new series of compounds 7 have been prepared from 2-iodopyrazine (1). Compound 1 on purged with ammonia gas in the presence of Cu2O and K2CO3 furnishes pyrazin-2-amine (2), which is treated with ethyl 3-bromo-2-oxopropanoate (3) to produce ethyl imidazo[1,2-a]pyrazine-2-carboxylate (4), which on hydrolysis with NaOH yields imidazo[1,2-a]pyrazine-2-carboxylic acid (5). The structures of the newly synthesized compounds have been elucidated on the basis of spectral (IR, 1H and 13C NMR and MS) and analytical data.

A novel series of chlorinated plastoquinone analogs: Design, synthesis, and evaluation of anticancer activity

Herein, we report the synthesis and cytotoxic effects of novel chlorinated plastoquinone analogs (ABQ1?17) against different leukemic cells. Compounds ABQ3, ABQ11, and ABQ12 demonstrated a pronounced antiproliferative effect against chronic myelogenous leukemia (CML) K562 cell line with IC50 values of 0.82 ¡À 0.07, 0.28 ¡À 0.03, and 0.98 ¡À 0.22 muM, respectively. Among them, ABQ11 showed approximately three times higher selectivity than imatinib on CML. ABQ11-treated CML cells induced significant apoptosis at low concentration. Inhibitory effect of ABQ11 against eight different tyrosine kinases, including ABL1, was investigated. ABQ11 inhibited ABL1 with IC50 value of 13.12 ¡À 1.71 muM, indicating that the moderate inhibition of ABL1 kinase is just an in-part mechanism of its outstanding cellular activity. Molecular docking of ABQ11 into ABL1 kinase ATP-binding pocket revealed the formation of some key interactions. Furthermore, DNA cleavage assay showed that ABQ11 strongly disintegrated DNA at 1 muM concentration in the presence of iron (II) complex system, assuming that the major mechanism for the anticancer effects of ABQ11 is DNA cleavage. In silico ADMET prediction revealed that ABQ11 is a drug-like small molecule with a favorable safety profile. Taken together, ABQ11 is a potential antiproliferative hit compound that exhibits unique cytotoxic activity distinct from imatinib.

Design, biological evaluation and 3D QSAR studies of novel dioxin-containing triaryl pyrazoline derivatives as potential B-Raf inhibitors

A series of novel dioxin-containing triaryl pyrazoline derivatives C1-C20 have been synthesized. Their B-Raf inhibitory and anti-proliferation activities were evaluated. Compound C6 displayed the most potent biological activity against B-RafV600E and WM266.4 human melanoma cell line with corresponding IC50 value of 0.04 muM and GI50 value of 0.87 muM, being comparable with the positive controls and more potent than our previous best compounds. Moreover, C6 was selective for B-RafV600E from B-RafWT, C-Raf and EGFR and low toxic. The docking simulation suggested the potent bioactivity might be caused by breaking the limit of previous binding pattern. A new 3D QSAR model was built with the activity data and binding conformations to conduct visualized SAR discussion as well as to introduce new directions. Stretching the backbone to outer space or totally reversing the backbone are both potential orientations for future researches.

Highly efficient resolutions of 1,4-benzodioxane-2-carboxylic acid with para substituted 1-phenylethylamines

The salts of (S)- and (R)-1,4-benzodioxane-2-carboxylic acid with eight (S)-1-arylethylamines were prepared. The determination of their melting points and of their solubilities in alcohol solvents revealed large differences between the diastereomeric benzodioxanecarboxylates of (S)-1-(p-nitrophenyl)ethylamine and of (S)-1-(p-methylphenyl)ethylamine. Therefore, these latter amines were selected to resolve (¡À)-1,4-benzodioxane-2-carboxylic acid by diastereoselective crystallization finding that both of them display a very high resolution ability for such a substrate, which contrasts with the null efficiency of unsubstituted 1-phenylethylamine. These results are consistent with DSC evidences, which indicated that the two successfully resolved diastereomeric systems are binary mixtures exhibiting a eutectic with a high content of the more soluble diastereomeric salt. The new procedures can advantageously replace the two resolutions we had previously reported, that of the same acid with dehydroabietylamine and that of glycerol acetonide, a precursor of 1,4-benzodioxane-2-carboxylic acid, with 1-phenylethylamine.

3-Phenylpropanoic acid-based phosphotyrosine (pTyr) mimetics: Hit evolution to a novel orally active protein tyrosine phosphatase 1B (PTP1B) inhibitor

Protein tyrosine phosphatase 1B (PTP1B) is a promising therapeutic target for type 2 diabetes. Herein, we report the evolution of a previously identified 3-phenylpropanoic acid-based PTP1B inhibitor to an orally active lead compound. A series of 3-phenylpropanoic acid-based PTP1B inhibitors were synthesized, and three of them, 3-(4-(9H-carbazol-9-yl)phenyl)-5-(3,5-di-tert-butyl-4- methoxyphenyl)-5-oxopentanoic acid (9), 3-(4-(9H-carbazol-9-yl)phenyl)-5- (4?-bromo-[1,1?-biphenyl]-4-yl)-5-oxopentanoic acid (10) and 3-(4-(9H-carbazol-9-yl)-2-fluorophenyl)-5-(4-cyclohexylphenyl)-5-oxopentanoic acid (16), showed IC50 values at sub-micromolar level. Further in vivo evaluation indicated the sodium salt of 9 not only exhibited significant insulin-sensitizing and hypoglycemia effects, but also decreased the serum levels of triglyceride and total cholesterol in high-fat-diet-induced insulin resistance model mice. Preliminary in vivo pharmacokinetic studies on the sodium salt of 9 revealed its pharmacokinetic profile after oral administration in rats. These results provide proof-of-concept for the dual effects of PTP1B inhibitors on both glucose and lipid metabolisms. A sincere form of flattery: A novel protein tyrosine phosphatase 1B (PTP1B) inhibitor with a 3-phenylpropanoic acid moiety as a phosphotyrosine (pTyr) mimetic was optimized to provide an orally active lead compound with an IC50 value of 0.40 muM against PTP1B and more notably that displayed significant in vivo activity in a murine insulin resistance model.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
