In vitro biological potential of Guanxuma-of-Horn [Sebastiania corniculata (Vahl) Mull. Arg.] in infection control

Medicinal plants with antimicrobial properties built into the problem of infection have been investigated, guide the discovery of efficient against the emerging pathogens herbal related to bacterial and fungal infection. This study aimed to enlarge the possibilities of knowledge about antibacterial and antifungal activities of this plant, in the treatment of infections. The results of antimicrobial activity and cytotoxicity of two fractions in MeOH/H2O from ethanol and acetone extracts of guanxuma-of-Horn [Sebastiania corniculata (Vahl) Mull. Arg.] (Euphorbiaceae) evaluated the extracts by disk diffusion test (DD) and the method of the Minimum Inhibitory Concentration (MIC). The extracts were active for Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus pneumoniae, Pseudomonas aeruginosa, Acinectobacter calcoaceticus and Proteus mirabilis in the DD test. However, the best results for these fractions were against P. aeruginosa with an MIC from 250 to 125 µg/mL, respectively. In the evaluation of cytotoxic for cell viability by MTT, only a dose of 100 µg/mL exhibited moderate cytotoxicity with p < 0.0001. In this perspective, the other extracts showed significant cytotoxicity, which suggests further research to evaluate the anti-tumor activity and consolidate the evidence obtained in the research present.

Antimicrobial activity of some of chlorocobaloximes containing axial substituted pyridines

Cobaloximes of the type [Co(dmgH)2(B)Cl] ; where, dmgH = dimethyl glyoximate, B= 3- chlorpyridine (3-PyCl), 3-bromopyridine (3-PyBr), 4-aminopyridine (4-AP), 4-methylpyridine (4-MP), 4-N,N’-dimethyl aminopyridine (4-DMAP) and 4-cyanopyridine (4-PyCN) were prepared, characterized by the usual spectroscopic techniques and screened against microorganism for antimicrobial activity with ciprofloxacin as standard. The cobaloximes were found to be active against most of the microbes. The cobaloxime containing 4-cyanopyridine as the axial ligand showed potential inhibition; whereas, the complex [Co(dmgH)2(3-PyCl)Cl] showed the least microbial growth.

Synthesis and Antimicrobial activity Evaluation of some Novel Pyrazolines

The pyrazoline nucleus is a ubiquitous feature of various therapeutically active compounds.They were reported to possess antimicrobial, antidiabetic, anticancer, antiHIV, antiamoebic, anthelmintic, anticonvulsant and tranquilizing activities. Therefore an attempt is made to synthesize novel pyrazolines from chalcones. All these synthesized compounds were characterized by means of their IR, 1H NMR, 13C NMR, and mass spectral data. These compounds were evaluated for antimicrobial activity by cup plate method.
