DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS

DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS Dendrimers are a new class of synthetic polymers which have a tree or star shape like structure, with a central core, interior branches and terminal groups which embellish the surface. It can be synthesized by a repetitive step-growth polymerization process. They are highly branched and monodisperse… read more: http://www.pharmatutor.org/articles/dendrimer-novel-system-in-pharmaceuticals Crystal… Continue reading DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS

Physicists Discover Theoretical Possibility of Large, Hollow Magnetic Cage Molecules

Illustration depicts a Mn24C18 cluster carrying a magnetic moment of 70 Bohr magnetons. (Credit: Image courtesy of Menghao Wu, Ph.D./VCU.) Virginia Commonwealth University researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and… Continue reading Physicists Discover Theoretical Possibility of Large, Hollow Magnetic Cage Molecules

240 boron atoms in a single molecular species

The cuboctahedron consists of copper paddle-wheel nodes and carborane–isophthalic acids Scientists in the US have made a molecular species containing the highest number of boron atoms ever recorded in a crystallographically characterised molecular species. The unique supramolecular cuboctahedron contains 240 boron atoms and was synthesised by Chad Mirkin and colleagues at Northwestern University in Evanston, Illinois, via coordination-driven… Continue reading 240 boron atoms in a single molecular species

History of Cyclotides

Cyclotides are head-to-tail cyclic peptides in plants Cyclotides are plant-derived peptides of approximately 30 amino acids. They have the characteristic structural features of a head-to-tail cyclized backbone and a cystine knot arrangement of their three conserved disulfide bonds. Their unique structural features lead to exceptional stability. This and their amenability to chemical synthesis have made… Continue reading History of Cyclotides

Chemists welcome newest member of nanocarbon family

The grossly warped nanographene has interesting optical and electronic properties © NPG A new family of nanocarbons has emerged with the growth of the first non-planar nanographene. Chemists from Boston College, US, and Nagoya University, Japan successfully synthesised a grossly warped nanographene by embedding non-hexagonal rings into a nanographene subunit. The unique structure was found… Continue reading Chemists welcome newest member of nanocarbon family

Coenzyme Q10

Coenzyme Q10 2-[(2E,6E,10E,14E,18E,22E,26E,30E,34E)-3,7,11,15,19,23,27,31,35,39-decamethyltetraconta-2,6,10,14,18,22,26,30,34,38-decaenyl]-5, 6-dimethoxy-3-methylcyclohexa-2,5-diene-1,4-dione Coenzyme Q10 (ubiquinone-10, CoQ10, CoQ, Q10 or simply Q) is aubiquinone containing 10 isoprenoid units. First discovered in 1957 by Crane et al. [1], its chemical structure was determined by Karl Folkers [2], who later won the Priestley medal from the American Chemical Society. This oil-soluble, vitamin-like micronutrient forms part of the electron transport chain which, in the process of… Continue reading Coenzyme Q10

The Bingel reaction in fullerene chemistry

Bingel fullerene The Bingel reaction in fullerene chemistry The Bingel reaction in fullerene chemistry is a fullerene cyclopropanation reaction to a methanofullerene first discovered by C. Bingel in 1993 with the bromo derivative of diethyl malonate in the presence of a base such as sodium hydride or DBU.[1] The preferred double bonds for this reaction on the fullerene surface are the shorter bonds at the junctions of two hexagons (6-6 bonds) and the driving… Continue reading The Bingel reaction in fullerene chemistry
