The compounds were synthesized in good yield and the structures of all newly synthesized compounds were established on the basis of their IR,1HNMR, and elemental analysis. The synthesized compounds were testedin vitroantibacterial activity againstStaphylococcus aureus,Escherichia coli,Pseudomonas aeruginosaandSalmonella typhiand antifungal activity againstAspergillus niger,Candida albicansby measuring the zone of inhibition in mm.

ABSTRACT: Medicinal Plants have been used throughout the world by human beings as a drug and remedies for various diseases since time immemorial. A study was planned to count into the antimicrobial activity and phytochemical screening of Euphorbia helioscopia. The plants were gathered and tested against some standard strains and some human pathogenic microorganisms i.e Escherichia coli, Bacillus Subtilis, Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhi, Pseudomonas aeruginosa and three fungal strain Trichoderma, R hizopus nigricans, Aspergillus niger. The concentrations of extracting samples (500 and 1,000 mg mL-1) were used against pathogens. Ciprofloxacin was used as positive control in case of bacterial strains and Colfrimazol was used against the fungal strain while dimethyl sulfoxide as negative control. The outcomes indicated that the positive wells potency of Water extract had a 36 mm diameter of zone of inhibition against Escherichia coli and ethanol extract at 1,000 mg mL-1 had maximum (34 mm) zone of inhibition against Bacillus subtilus (36 mm) zone of inhibition against Klebsiella pneumonia and 33 mm of zone of inhibition against Trichoderma harzianum. Likewise, water extract at a concentration of 1,000 mg mL-1 resulted highest value of zone of inhibition (36 mm) against Staphylococcus aureus, a zone of inhibition ( mm) against Salmonella typhi, 36 mm zone of inhibition against Pseudomonas aeruginosa, (32 mm) zone of inhibition against Rhizopus nigricans, a 34 mm zone of inhibition against Acremonium and (34 mm) zone of inhibition against Aspergillus niger. The most susceptible bacteria were K. pneumonia and Bacillus subtilis, while E. coli was the most resistant bacteria and showed zone of inhibition. The ethanolic extract had tannins, lipid, total proteins, carbohydrates, flavonoids, Alkaloid and polyphenolics.

Schiff Base Derivatives

5A novel series of thiazolidinone derivatives, namely 4-{4-dimethylamino-6-[4-oxo- 2-phenyl-5-(4-pyridin-2-yl-piperazin-1-ylmethyl)-thiazolidin-3-yl]-[1,3,5]-triazin-2-yloxy}- 1-methyl-1H-quinolin-2-ones, have been synthesized from the key intermediate 4-(4-amino- 6-dimethylamino-[1,3,5]-triazin-2-yloxy)-1-methyl-1H-quinolin-2-one (). Compound 5 was condensed with various aldehydes to give Schiff base derivatives, which after cyclization gave thiazolidinones that were linked with 1-pyridin-2-yl-piperazine to obtain the target compounds. The newly synthesized compounds were evaluated for their antimicrobial activity against eight bacteria (Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, Shigella flexneri) and four fungi (Aspergillus niger, Candida albicans, Aspergillus fumigatus, Aspergillus clavatus)

Three bis-acetylferrocene schiff bases have been synthesized and characterized by IR, 1H NMR, and elemental analysis, the results conformed well with expected structures. The synthesized compounds were screened in vitro for their antimicrobial activity against three Gram-negative (Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi) and two Gram-positive (Bacillus subtilis and Staphylococcus aureus) bacterial strains. The results showed that these compounds are show excellent antimicrobia activities against Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi ,Bacillus subtilis,Staphylococcus aureus.

The aim of this study was to investigate the probiotic potential of bacteriocin-producing lactobacilli strain Lactobacillus plantarum G2 isolated from the vaginal mucus of healthy women. The antimicrobial effect of G2 was confirmed in the mixed culture with pathogenic Escherichia coli, Staphylococcus aureus, Salmonella abony and Pseudomonas aeruginosa, while bacteriocine activity was detected against S. aureus and S. abony only. The strain showed an excellent survival rate in low pH and in the presence of bile salts. The percentage of adhered cells of L. plantarum G2 to hexadecane was 63.85?2.0 indicating the intermediate hydrophobicity.
