To purify and characterize antimicrobial compounds from Bacillus sp. strain N associated with rhabditid entomopathogenic nematode (EPN).The cell-free culture filtrate of a bacterium an EPN, Rhabditis (Oscheius) sp., exhibited strong activity. The ethyl acetate extract the bacterial was purified by silica gel column chromatography to obtain three diketopiperazines (DKPs). structure absolute stereochemistry this compound were determined based on extensive spectroscopic analyses (FABMS, (1) H...
The trinuclear [Cu3(RCOO)4(H2TEA)2] copper(II) complexes, where RCOO– = 2-furoate (1), 2-methoxybenzoate (2), and 3-methoxybenzoate (3, 4), as well dimeric species [Cu2(H2TEA)2(RCOO)2]·2H2O, have been prepared by adding triethanolamine (H3TEA) at ambient conditions to hydrated Cu(RCOO)2 salts. newly synthesized complexes characterized elemental analyses, spectroscopic techniques (IR UV–visible), magnetic susceptibility, single crystal X-ray structure determination theoretical calculations,...
The interaction of three newly synthesized copper(<sc>ii</sc>) mefenamate complexes with bovine/human serum albumin was studied by fluorescence emission spectroscopy.
Design, synthesis, detailed structural characterization and potential biological efficacy of copper( ii ) chloro-benzoato complexes displaying the synergistic role steric constraints non-covalent interactions have been carried out for first time.
A new microbial cyclic dipeptide (diketopiperazine), cyclo(d-Tyr-d-Phe) was isolated for the first time from ethyl acetate extract of fermented modified nutrient broth Bacillus sp. N strain associated with rhabditid Entomopathogenic nematode. Antibacterial activity compound determined by minimum inhibitory concentration and agar disc diffusion method against medically important bacteria recorded significant antibacterial test bacteria. Highest Staphylococcus epidermis (1 µg/ml) followed...
In this work, green method to synthesize chromium-doped zinc oxide (ZnO) nanorods (NRs) using an aqueous flower extract from Rhododendron arboretum is explored. Herein, ZnO NRs were prepared with different amount of chromium doping, varied as 2–10%. The synthesized products underwent substantial analysis through X-ray diffraction (XRD), spectroscopic such ultraviolet spectroscopy(UV-Vis) and scanning electron microscopy (SEM) methods. All samples found have hexagonal wurtzite ZnO, average...
The cytotoxic effects of four new Ibuprofen–Cu(<sc>ii</sc>) complexes were tested finding significant cytotoxicity on human melanoma cell line HT-144.

Respiratory illnesses have been linked to children's exposures water-damaged homes. Therefore, understanding the microbiome in homes is critical preventing these illnesses. Few studies quantified bacterial contamination, especially specific species, We collected air and dust samples twenty-one low-mold high-mold The concentrations of three bacteria/genera, Stenotrophomonas maltophilia, Streptomyces sp., Mycobacterium were measured using quantitative PCR (QPCR). bacteria not associated with...
Enhanced antifungal activity against the yeast species <italic>Candida albicans</italic>, tropicalis</italic> and <italic>Saccharomyces cerevisiae</italic> was displayed by ZnS–ZnO nanocomposites prepared a simple precipitation technique.
Multinuclear (di/tri) copper(II) complexes bridged through hydroxyl groups are very interesting coordination owing to their potential applications in various fields. In this work, three novel dinuclear (μ-hydroxo)-bridged the crystal form, namely, [Cu
