Drug resistance is a multifactorial phenomenon that limits the action of antibiotics and chemotherapeutics. Therefore, it is essential to develop new therapeutic strategies capable of inducing cytotoxic effects circumventing chemoresistance. In this regard, the employment of natural and synthetic cationic peptides and polymers has given satisfactory results both in microbiology, as antibacterial agents, but also in the oncological field, resulting in effective treatment against several tumors, including neuroblastoma (NB). To this end, two polystyrene-based copolymers (P5, P7), containing primary ammonium groups, were herein synthetized and tested on etoposide-sensitive (HTLA-230) and etoposide-resistant (HTLA-ER) NB cells. Both copolymers were water-soluble and showed a positive surface charge due to nitrogen atoms, which resulted in protonation in the whole physiological pH range. Furthermore, P5 and P7 exhibited stability in solution, excellent buffer capacity, and nanosized particles, and they were able to reduce NB cell viability in a concentration-dependent way. Interestingly, a significant increase in reactive oxygen species (ROS) production was observed in both NB cell populations treated with P5 or P7, establishing for both copolymers an unequivocal correlation between cytotoxicity and ROS generation. Therefore, P5 and P7 could be promising template macromolecules for the development of new chemotherapeutic agents able to fight NB chemoresistance.

In this report, the synthesis of amides from aldoximes (Beckmann rearrangement) has been reported using cobalt(II) porphyrin covalently linked to graphene oxide as a nano heterogeneous catalyst. The prepared catalyst was characterized by applying of FT-IR, TGA, TEM, SEM, EDX, ICP and UV-Vis techniques. All analyses confirm the successful insertion of cobalt into the porphyrin ring and covalently linkage of Co-Porphyrin on the graphene oxide. Moreover, the prepared catalyst was applied in order to investigate its performance in the Beckmann rearrangement. This heterogeneous catalyst exhibited excellent catalytic efficiency with a high yield of products. Also, the suggested catalyst could be recycled for five runs without a dramatic decrease in its catalytic activity or metal leaching.

Background: Due to the presence of several serious side effects such as erosion and bleeding in the gastric mucosal layer which are linked with Non-steroidal anti-inflammatory agents and a lot of these adverse effects may be dangerous for life and may cause numerous mortalities, demand for new antiinflammatory and analgesic agents has become an important task in medicinal chemistry to improve therapeutic efficacy as well as safety. Method: In the search for new anti-inflammatory and analgesic molecules with greater potency, some novel indole derivatives (SK-1 to SK-9) were attained by chloroacetylation process of indole after that reaction through some aromatic aldehydes with the presence of acetic acid in absolute ethyl alcohol. IR, H-1 NMR, and C-13 NMR spectra were used for the structure elucidation of obtained chemical compounds. In this context, the analgesic and anti-inflammatory activity were evaluated for synthetically obtained new chemical compounds. Furthermore, the molecular docking studies were performed to elucidate the binding modes of synthesized ligands in the active pockets of Cox-1 / 2 enzymes. Result: Among the compounds assessed, SK-2 and SK-8 demonstrated potent analgesic & antiinflammatory activities when compared to ibuprofen and diclofenac sodium as reference drugs. Compound SK-4 has exhibited significant anti-inflammatory activity while compounds SK-1 and SK-5 have shown significant analgesic action when compared to the control. Molecular docking studies indicated that SK2 compound exhibited appreciable binding affinity (-9.16 kcal/mol) towards the COX-2 enzyme and mandatory interactions for COX-2 enzyme inhibition. Conclusion: It might be established from the present study that prepared compounds are unique in terms of their structure and noticeable biological action. In search of and initiation of a novel group of antiinflammatory and analgesic molecules, these compounds might be helpful. (C) 2020 Elsevier B.V. All rights reserved.

Main observation and conclusion High CO pressure (> 40 bar) is usually needed in radical carbonylation reactions in the absence of metal catalyst. In this communication, we developed a transition-metal-free radical carbonylation of activated alkylamines with phenols and alcohols under low CO pressure (1-6 bar). Various esters were obtained in moderate to excellent yields under simple reaction conditions with good functional group compatibility.

Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small molecule synthesis remains underdeveloped due to their moderate-poor electrochemical potential in the ground state, whereas some of them are characterized by photoabsorptions in visible spectral regions. Herein, we disclose the use of polysulfide anions as visible light photoredox catalysts for aryl cross-coupling reactions. The reaction design enables single-electron reduction of aryl halides upon the photoexcitation of tetrasulfide dianions (S-4(2-)). The resulting aryl radicals are engaged in (hetero)-biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S-4(center dot-) and S-4(2-)/S-3(center dot-)/S-3(2-) redox couples.

Starting from diverse alkene-tethered aryl iodides and O-benzoyl-hydroxylamines, the enantioselective reductive cross-electrophilic 1,2-carboamination of unactivated alkenes was achieved using a chiral pyrox/nickel complex as the catalyst. This mild, modular, and practical protocol provides rapid access to a variety of beta-chiral amines with an enantioenriched aryl-substituted quaternary carbon center in good yields and with excellent enantioselectivities. This process reveals a complementary regioselectivity when compared to Pd and Cu catalysis.

Genome sequencing of environmental bacteria allows identification of biosynthetic gene clusters encoding unusual combinations of enzymes that produce unknown natural products. We identified a pathway in which a ribosomally synthesized small peptide serves as a scaffold for nonribosomal peptide extension and chemical modification. Amino acids are transferred to the carboxyl terminus of the peptide through adenosine triphosphate and amino acyl-tRNA-dependent chemistry that is independent of the ribosome. Oxidative rearrangement, carboxymethylation. and proteolysis of a terminal cysteine yields an amino acid-derived small molecule. Microcrystal electron diffraction demonstrates that the resulting product is isosteric to glutamate. We show that a similar peptide extension is used during the biosynthesis of the ammosamides, which are cytotoxic pyrroloquinoline alkaloids. These results suggest an alternative paradigm for biosynthesis of amino acid-derived natural products.
