Green synthesis method is being increasingly used in the development of safe, stable, and eco-friendly nanostructures with biological resources. In this study, extracellular and intracellular synthesis of gold nanoparticles (AuNPs) was carried out using green algae Chlorella sorokiniana Shihira & R.W. Fresh algae were isolated and identified from Musaözü Pond located in the province of Eskişehir and then extraction process were performed.

The objective of the present investigation was to isolate and identify the antimicrobial activity showing actinomycetes associated with sponges. Sponges such as Acanthella klethra, Theonella cylendrica, Helicona sp., Auletta sp., and Callyspongia sp. were collected at Sangumal, in Rameswaram island, Ramanathapuram District, Tamil Nadu, India. Isolates of 22 actinomycetes were isolated from sponges. Isolates No. 16 showed high antibacterial and antifungal activity and the isolate was identified as Streptomyces sp.

Recently, some of the furoquinoline alkaloids were found to have an interesting biological activity, for example, anti-cancer, antiplatelet aggregation and antifungal activities. The interesting biological activity made these compounds 1-13 attractive targets in organic chemistry. A novel generally applicable synthesis of furoquinolines is described. The condensation of 2- methoxy aniline and malonic acid in the presence of POCl3 gave 2,4-dichloro-8- methoxyquinoline. Then, treatment of this compound with sodium methoxide in methanol under reflux afforded 4,8-dimethoxyquinoline.

The lupane triterpenoid lupeol is found in a variety of plants. Its biological activities have attracted a great deal of interests. A number of studies on the antiinflammatory, antimycobacterial, antimalarial and anticancer activities of this compound and its derivatives have been reported. Based on our knowledge, there have not been any reports on the antimicrobial activity of lupeol and its derivatives.

Croton tonkinensis Gagnep., commonly named in Vietnamese as "Kho sam Bac Bo", is a tropical shrub native to the Northern Vietnam. Its dried leaves (Folium Tonkinensis) have been used in Vietnamese traditional medicine to treat boils, abscesses, impetigo, abdominal pain, dyspepsia, dysentery, gastric and duodenal ulcers [1, 2]. The plant is of our interest since its varied biological activities demonstrated in our various in vitro bioassays including anti-inflammatory, anticancer, antiplasmodial, antibacterial and antifungal.

Glycosylatedpolyenemacrolide antibiotics, as nystatins and amphotericins, are amphiphilic structures known to exert antifungal activity by disrupting the fungal cell membrane, leading to leakage of cellular materials, and cell death. This membrane disruption is strongly influenced by the presence and the exact nature of the membrane sterols.

Tarocystatin from Colocasia esculenta, a group-2 phytocystatin, is a defense protein against phytopathogenic nematodes and fungi. It is com-posed of a highly conserved N-terminal region, which is homological to group-1 cystatin, and a repetitive peptide at the C-terminus.

The term ‘antimicrobial peptides’ refers to a large number of peptides first characterized on the basis of their antibiotic and antifungal activities. In addition to their role as endogenous antibiotics, antimicrobial peptides, also called host defense peptides, participate in multiple aspects of immunity (inflammation, wound repair, and regulation of the adaptive immune sys-tem) as well as in maintaining homeostasis.

Whereas significant knowledge is accumulating on the antibacterial and antifungal properties of host defense peptides (HDPs) and their synthetic mimics, much less is known of their activities against parasites. A variety ofin vitro andin vivo antiparasitic assays suggest that these notorious anti-microbial compounds could represent a powerful tool for the development of novel drugs to fight parasites in the vertebrate host or to complement current therapeutic strategies

A cDNA library from tobacco inoculated withRhizoctonia solaniwas con-structed, and several cDNA fragments were identified by differential hybridization screening. One cDNA clone that was dramatically repressed, NtKTI1, was confirmed as a member of the Kunitz plant proteinase inhibi-tor family. RT-PCR analysis revealed that NtKTI1was constitutively expressed throughout the whole plant and preferentially expressed in the roots and stems.

The natural antimicrobial cationic peptide protegrin-1 displays a broad spectrum of antimicrobial activity and rapidly kills pathogens by interacting with their cell membrane. We investigated the structure–activity relation-ships of three protegrin-1 analogues: IB-367 (RGGLCYCRGRFCVCVGR-NH2), BM-1 (RGLCYCRGRFCVCVG-NH2) and BM-2 (RGLCYRPRFV CVG-NH2). Our antimicrobial and antifungal activity studies of these peptides showed that BM-1 was much more active than IB-367 against Gram-positive bacteria and fungi, whereas BM-2 was inactive. ...
