Mycosynthesis: antibacterial, antioxidant and antiproliferative activities of silver nanoparticles synthesized from Inonotus obliquus (Chaga mushroom) extract.

In the present study, silver nanoparticles (AgNPs) were rapidly synthesized from silver nitrate solution at room temperature using Inonotus obliquus extract. The mycogenic synthesized AgNPs were characterized by UV-Visible absorption spectroscopy, Fourier transform infrared (FTIR), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) and atomic force microscopy (AFM). SEM revealed mostly spherical nanoparticles ranging from 14.

Evaluation of thiosemicarbazone derivative as chelating agent for the simultaneous removal and trace determination of Cd(II) and Pb(II) in food and water samples.

In the present investigation, prepared N-ethyl-3-carbazolecarbaxaldehyde-3-thiosemicarbazone (ECCT) and employed for the simultaneous removal and determination of trace amounts of Cd(II) and Pb(II) from food and water samples. Cd(II) and Pb(II) gave yellow and orange colored complexes with ECCT in acetate buffer at pH 6.0 with λmax, 380 and 440nm, respectively.

Green synthesis of silver nanoparticles using Nelumbo nucifera seed extract and its antibacterial activity.

Silver nanoparticles (AgNPs) were synthesized using a Nelumbo nucifera dry seed extract, which is a simple, non-toxic, eco-friendly "green material". The synthesized nanoparticles were confirmed by the color changes and characterized by UV-visible spectroscopy. The AgNPs were stable at room temperature for 2 months.

Synthesis and antiproliferative activity of novel α-aminophosphonates.

A novel series of carbazole-based α-aminophosphonates were synthesized by three component coupling of 6-bromo-9-ethyl-9H-carbazole-3-carbaldehyde, amine and diethyl phosphite using polyethylene glycol (PEG-400) as a green reaction media. The antiproliferative activity of these molecules was evaluated against three cancer cell lines. Of these, compounds 4c, 4e and 4m were found to exhibit good antiproliferative activity against three cancer cells, A549, MCF-7, and NCI-N87.

Glyscavins A, B and C, new phenolic glycoside antioxidants produced by a fungus Mycelia sterilia F020054.

Three new phenolic glycosides designated glyscavins A (1), B (2), and C (3) were isolated from the culture broth of a fungal strain Mycelia sterilia F020054. Structural elucidation of the compounds was based on the NMR and MS spectroscopic analyses. Glyscavins A, B and C exhibited higher free radical scavenging activity on superoxide and 2,2'-azinobis(3-ethylbenzothialozinesulfonic acid) cation radical (ABTS*+) than butylated hydroxyanisole (BHA).

pat-4/ILK and unc-112/Mig-2 are required for gonad function in Caenorhabditis elegans.

Tissue morphogenesis requires proper interaction between cells and the extracellular matrix (ECM), which is mediated by alphabeta heterodimeric receptor integrin. In Caenorhabditis elegans, integrin signaling is essential for formation of gonad. Here, we probe the role of several integrin-associated molecules in ovulation and cell migration.

[structure: see text] A new cavitand bearing four imidazolium groups was synthesized for the recognition of anions through (C-H)+...

Synthesis and photochemical protein crosslinking studies of hydrophilic naphthalimides.

A mixture of 4-alkylamino-1,8-naphthalimides has previously been reported to exhibit potential utility as a photochemical tissue-bonding reagent. In order to determine which constituents of the mixture were responsible for the observed tissue bonding and to facilitate study of the mechanism, we have synthesized each of the primary constituents of the mixture. Each naphthalimide synthesized has been demonstrated to photochemically crosslink proteins.
