Dimethyl carbonate (DMC), an environment-friendly compound prepared from CO2, shows diverse reactivities. In this communication, an efficient procedure using DMC as both a C1 building block and solvent in the aminocarbonylation reaction with nitro compounds has been developed. W(CO)6 acts both a CO source and a reductant here.

Objective: To evaluate the available evidence comparing the use of the bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) regimen for 6 months with that of standard-of-care regimens for patients with multidrug-resistant or rifampin-resistant tuberculosis (MDR/RR-TB).
Methods: This was a systematic review of clinical trials comparing the use of the BPaLM regimen with the standard of care in patients with MDR/RR-TB. The main outcome measure was an unfavorable endpoint (a composite of death, treatment failure, treatment discontinuation, loss to follow-up, and recurrence), and secondary outcome measures included adverse events and serious adverse events.

Sitobion miscanthi is a wheat aphid species that can damage seriously agricultural production. The effective management of wheat aphids has depended on chemical insecticides. However, their wide application led to severe resistance of wheat aphids to some insecticides, and cytochrome P450 as a detoxifying enzyme plays a crucial role in the insecticide resistance.

Recent advances in cancer therapy have been made possible by monoclonal antibodies, domain antibodies, antibody drug conjugates, The most impact has come from controlling cell cycle checkpoints through checkpoint inhibitors. This manuscript explores the potential of a series of novel -benzyl isatin based hydrazones (5-25), which were synthesized and evaluated as anti-breast cancer agents. The synthesized hydrazones of -benzyl isatin were screened against two cell lines, the MDA-MB-231 breast cancer cell line and the MCF-10A breast epithelial cell line.

The initial decomposition reactions of 1,3,5-trinitrobenzene (TNB), picric acid (PA), 2,4,6-trinitrotoluene (TNT), 2,4,6-trinitroaniline (TNA) and 2,4,6-trinitrophenylmethylnitramine (Tetryl) were studied using ReaxFF-lg molecular dynamics simulations, and the substituent effect on the thermal decomposition behaviours of nitrobenzene compounds was evaluated through the reactant number, initial decomposition pathway, products and cluster analysis. The results show that the introduction of substituents could promote the decomposition of the reactants, increase the frequency of the nitro-nitrito isomerization reaction and intermolecular H or O atom transfer reaction, and reduce the frequency of the direct nitro dissociation reaction. Notably, these effects were most obvious in the case of TNT.
