An elegant synthesis of newer aminobenzylated mannich bases (6a to 6j) is described in the present study. These were synthesized by reacting aromatic aldehydes, cyclic secondary amines and a reagent with active hydrogen atom such as Urea in the presence of hydrochloric acid. The constituents of the newly synthesized compounds have been established on the basis of their physical and spectral dat...

The aim of the study is to evaluate the antibacterial activity of Pistacia integerrima, Cedrus deodara and Gymnema sylvestre against seven different microorganisms such as Escherichia coli, Salmonella typhi, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas, Bacillus subtillis and Staphylococcus aureus by using disc diffusion method. Preliminary studies with ethanol extract and water extract...

Biophytum sensitivum (L.) DC. (Oxalidaceae) is an ethnomedicinal plant used in folklore medicine. The main aim of this study demonstrates that the leaves extracts of B. sensitivum (methanol, chloroform, acetone, and petroleum ether) was evaluated for its antibacterial activity against several human pathogenic bacterial strains (Bacillus subtillis, Staphylococcus aureus, Streptococcus pneumonia,...

Six bacteria (Bacillus velezensis 13, Bacillus subtillis 42, Pseudomonas fluorescens E221, Poae EE12, Rahnella sp. EM1, and Serratia EM2) isolated from the soil litter of Mexican oak forests were characterized by identifying their ability to acquire phosphorus different sources, analyzed for biocontrol capabilities against two phytopathogenic fungi, finally tested stimulate germination maize se...

Micromonospora genus produces >700 bioactive compounds of medical relevance. In spite of its ability to produce high number of bioactive compounds, no genome sequence is available with comprehensive secondary metabolite gene clusters analysis for anti-microbial producing Micromonospora strains. Thus, here we contribute the full genome sequence of Micromonospora sp. HK10 strain, which has high a...
