A new series of N-[3-(10H-phenothiazin-1-yl)propyl]-4-(substituted phenyl)-3-chloro-2-oxo-1-azetidinecarboxamide 4(a–m) have been synthesized from phenothiazine in four steps. Phenothiazine on reaction with Cl(CH2)3Br at room temperature gave 1-(3-chlorophenyl)-10H-phenothiazine, 1. The compound 1 yielded the condensation product with urea at room temperature, N-[3-(10H-phenothiazin-1-yl)propyl]urea 2. The compound 2 on further reaction with several substituted aromatic aldehydes produced N-[3-(10H-phenothiazin-1-yl)propyl]-N′-[(substituted phenyl)methylidene]-urea 3(a–m). The compounds 3(a–m) on treatment with ClCH2COCl in the presence of Et3N furnished final products 4(a–m). The structures of all the newly synthesized compounds were confirmed by IR, 1H NMR, 13C NMR and FAB-Mass spectra and chemical methods. All the final synthesized compounds were evaluated for their antibacterial, antifungal and antitubercular activities which displayed acceptable activities. Graphical Abstract A new series of N10-3-{(4-substituted aryl-3-chloro-2-oxo-azetidine)-carbamyl}-propylphenothiazine, compounds 4(a–m) were synthesized and screened for their antibacterial, antifungal and antimycrobial activities in vitro.

Plant parasitic nematodes are the most destructive group of plant pathogens worldwide and their control is extremely challenging. Plant Essential oils (EOs) and their constituents have a great potential in nematode control since they can be developed for use as nematicides themselves or can ... more
For over a century, ulcer has been a major cause of morbidity and mortality. Its treatment has progressed from vagotomy to proton pump inhibitors. However, the drugs used produce many adverse effects and are less effective than they ought to be. Therefore, there is a growing interest in alt ... more
Endophytic fungi are ubiquitous organisms found in the plants, residing intercellular or intracellular, at least for a portion of their lives without causing apparent symptoms of infection. Almost all plants are known to harbor endophytes. The choice of the plant to be used for exploring en ... more
Physicists describe how they have synthesized a new material that belongs to the iron-selenide class of superconductors, called LixFe2Se2(NH3)y, in a paper about to be published in EPJ B. The work was carried out by Ernst-Wilhelm Scheidt from the University of Augsburg and colleagues. This ... more
The U.S. federal government is significantly underestimating the costs of carbon pollution because it is using a faulty analytical model, according to a new study published in the Journal of Environmental Studies and Sciences. A more appropriate accounting of costs would pave the way to cle ... more
