Synthesis of cyclic carbonates with carbon dioxide and cesium carbonate
Cyclic carbonates are important compounds for the synthesis of biocompatible polymers and linear dialkyl carbonates, as well as solvents and electrolytes. We report here the synthesis of such compounds from easily accessible starting materials with carbon dioxide as a C1 source and caesium carbonate as the base. This new methodology is able to yield… Continue reading Synthesis of cyclic carbonates with carbon dioxide and cesium carbonate
Even bacteria use social networks
This model shows the role of vesicles, vesicle chains and membrane tubes in M. xanthus biofilms. The scientists believe these connections help cells exchange signals and material. Image: Auer laboratory Using several imaging techniques, Lawrence Berkeley National Laboratory scientists found that a common soil bacterium stays connected by a network of chain-like membranes. They… Continue reading Even bacteria use social networks
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

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
AVANAFIL, NEW DRUG FOR ERECTILE DYSFUNCTION, FDA APRIL 2012
Avanafil is a PDE5 inhibitor approved for erectile dysfunction on April 27, 2012.[1] Avanafil is known by the trademark name Stendra and was developed by Vivus Inc. It acts by inhibiting a specific phosphodiesterase type 5 enzyme which is found in various body tissues, but primarily in the corpus cavernosum penis, as well as the retina. Other similar drugs are sildenafil, tadalafil and vardenafil. The advantage of avanafil is that… Continue reading AVANAFIL, NEW DRUG FOR ERECTILE DYSFUNCTION, FDA APRIL 2012
