An electrochemical four-component reaction cascade Mumm rearrangement was developed. It is a rare example of in situ generation of O-acyl isoamides for 1,3-(O -> N) acyl transfer. Inexpensive, commercially available arylethylenes, aryl or heterocyclic acids, acetonitrile, and alcohols were used as substrates. A wide range of aryl acids and alcohols were tolerated and provided imides in satisfactory yields. Subsequent hydrolysis of imides could be utilized to synthesize valuable amides and beta-amino alcohol derivatives.

Matrix metalloproteinases (MMPs) are major modulators of the tumor microenvironment. They participate in extracellular matrix turnover, tumor growth, angiogenesis and metastasis. Accordingly, MMPs inhibition seems to be ideal solution to control cancer. Many MMPs inhibitors have been introduced ranging from hydroxamate-based peptidomimetics to the next generation non-hydroxamate inhibitors. Among MMPs, MMP-9 is attractive druggable anticancer target. Studies showed that inhibiting AKT, the central signaling node of MMP-9 upregulation, provides additional MMP-9 blockade. Furthermore, caspase-dependent AKT cleavage leads to cell death. Herein, Ugi MCR was utilized as a rapid combinatorial approach to generate various decorated bis-amide scaffolds as dual MMP-9/AKT inhibitors endowed with caspase 3/7 activation potential. The target adducts were designed to mimic the thematic structural features of non-hydroxamate MMP inhibitors. p-Nitrophenyl isonitrile 1 was utilized as structure entry to Ugi products with some structural similarities to amide-based caspase 3/7 activators. Besides, various acids, amines and aldehydes were employed as Ugi educts to enrich the SAR data. All adducts were screened for cytotoxicity against normal fibroblasts and three cancer cell lines; MCF-7, NFS-60 and HepG-2 utilizing MTT assay. 8,11 and 28 were more active and safer than doxorubicin with single-digit nM IC50 and promising selectivity. Mechanistically, they exhibited dual MMP-9/AKT inhibition at single-digit nM IC50 with excellent selectivity over MMP-1,-2 and -13, and induced >51% caspase 3/7 activation. Consequently, they induced >49% apoptosis as detected by flow cytometric analysis, and inhibited cell migration (metastasis) up to 97% in cancer cells. Docking simulations were nearly consistent with enzymatic evaluation, also declared possible binding modes and essential structure features of active compounds. In silico physicochemical properties, ligand efficiency and drug-likeness metrics were reasonable for all adducts. Interestingly, 8 and 28 can be considered as drug-like candidates.

A highly-efficient catalytic system for hydrodebenzylation reaction is described. The cleavage of O-benzyl and N-benzyl protecting groups was performed using an uncommonly low palladium loading (0.02-0.3 mol%; TON up to 5000) in a relatively short reaction time. The approach was used for a variety of substrates including pharmaceutically important precursors, and gram-scale deprotection reaction was shown. Transfer conditions together with easy-to-make Pd/C catalyst are the key features of this debenzylation scheme.

Bench- and air-stable 1-methoxy-2,2,6,6-tetra-methylpiperidine (TEMPO-Me) is relatively unreactive at ambient temperature in the absence of an electrochemical stimulus. In this report, we demonstrate that the one-electron electrochemical oxidation of TEMPO-Me produces a powerful electrophilic methylating agent in situ. Our computational and experimental studies are consistent with methylation proceeding via a S(N)2 mechanism, with a strength comparable to the trimethyloxonium cation. A protocol is developed for the electrochemical methylation of aromatic acids using TEMPO-Me.

A new, modified total synthesis of (-)-cleistenolide (1) and sixteen new analogues or derivatives was achieved starting from commercially available 1,2-O-isopropylidene-alpha-D-glucofuranose. The synthesis of 1 proceeds in six steps and 67% overall yield, using single-carbon atom degradation of a protected chiral precursor, (Z)-selective Wittig olefination, and acid catalyzed delta-lactonization. A new Lewis acid promoted procedure for one-pot O-debenzylation/O-acylation has been developed to complete the synthesis of natural product 1 and selected analogues. The synthesized compounds were tested in vitro to evaluate their cytotoxicity against K562, HL-60, Jurkat, Raji, MCF-7, MDA-MB 231, HeLa, A549, and MRC-5 cell lines. All (-)-cleistenolide analogues exhibited significantly higher cytotoxicity than lead 1 against the majority of cell lines tested. Most of the synthesized compounds are more active than doxorubicin on at least one malignant cell line, but were almost completely inactive against normal MRC-5 cells. The structural features of the tested compounds responsible for their antiproliferative activity have been identified by preliminary SAR analysis. (C) 2020 Elsevier Masson SAS. All rights reserved.

Three series of azo dyes derived from 2-amino-5-aryl-1,3,4-thiadiazoles and aniline,N,N-dimethylaniline and phenol were synthesized in high yields by a conventional diazotization-coupling sequence. The chemical structures of the prepared compounds were confirmed by(1)H-NMR,C-13-NMR, IR, UV-Vis spectroscopy, mass spectrometry and elemental analysis. In addition, the X-ray single crystal structure of a representative azo dye was presented. For explicit determination of the influence of a substituent on radiation absorption in UV-Vis range, time-dependent density functional theory calculations were performed.

Modifying the surface of metal catalyst is a crucial subject for improving the heterogeneous metal catalysts. It is still a great challenge to understand the structure-activity relationship (SAR) between the surface supporting groups and the metal particles. Herein, Rh NPs supported on the magnetic silica sphere with various functional groups (-NH2, -SH, -SO3H, -N=CH2, -Cl, -NHCOCH3 and -NHCH2Ph) have been prepared for catalytic hydrogenation of nitroarenes under atmospheric pressure at room temperature. We discover that the chemical state of Rh NPs depends on the supporting groups significantly. The electron-donating functionalities can effectively elevate the Rh-0/Rh3+ ratio, which increase the catalytic performance both in conversion and selectivity. The amino group decorated catalyst has such a good selectivity that no dechlorination reaction is observable in the hydrogenation of 2-chloro-3-nitropyridine. What’s more, by introducing magnetic Fe3O4 nuclei and mesoporous silica encapsulating layer, the catalyst can be recovered conveniently by an external magnet, and can be reused 10 cycles without any loss of activity.

Category: phthalazines. I found the field of Chemistry very interesting. Saw the article Novel Pyrazolo[3,4-d]pyrimidine-Containing Amide Derivatives: Synthesis, Molecular Docking, In Vitro and In Vivo Antidiabetic Activity published in 2019, Reprint Addresses Kiran, G (corresponding author), Anurag Grp Inst, Dept Pharmaceut Anal & Chem, Sch Pharm, Ghatkesar M, Telangana, India.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid.

A new series of Pyrazolo[3,4-d]pyrimidine containing amide derivatives (8 a-l) were designed, synthesized, and evaluated for their in vitro alpha-amylase inhibitory activity. The IC50 values of the target compounds ranged from 1.60 +/- 0.48 to 2.04 +/- 1.20 mu M as compared to the standard acarbose 1.73 +/- 0.05 mu M. All the Pyrazolo[3,4-d]pyrimidine amide derivatives displayed good inhibitory activities, while seven analogs (8 d, 8 f, 8 g, 8 h, 8 i, 8 j and 8 k) exhibited more or less equipotent activity with IC50 values 1.77 +/- 2.84, 1.65 +/- 0.45, 1.66 +/- 2.24, 1.73 +/- 0.37, 1.60 +/- 0.48, 1.75 +/- 0.36 and 1.64 +/- 0.03 mu M respectively. Further, the most potent alpha-amylase inhibitors 8 d and 8 k were also screened for their in vivo antidiabetic activity against alloxan induced diabetic rat model at the dose of 25 and 50 mg/kg. Oral administration of these tested compounds significantly reduced the fasting blood glucose levels in dose dependent manner. The hypoglycemic effects of these compounds were more evident at 3 h and 5 h after administration of tested compounds which was similar to the effect displayed by the positive control. In addition, the binding energies calculated from the docking studies with the alpha-amylase enzyme (PDB ID: 1HNY) and biological activities indicate that the compounds containing nitro moiety on the phenyl group contributed significantly towards the antidiabetic activity.
