Hollow organic solids

Article Abstract:

J. Wuest and colleagues have described the design and preparation of a crystalline organic zeolite host that forms large molecular channels as well as accommodates labile guests that can be reversed without the loss of crystallinity. Using inorganic zeolites' structural analogy, these researchers have shown that closest packing molecular organization can be avoided through supramolecular networks with strong, selective and directional noncovalent interactions such as hydrogen bonds or metal coordination bonds.

Taking stock of PI-PLC

Article Abstract:

The phosphoinositide-specific phospholipase C (PI-PLC) enzyme family is receptor-controlled and catalyzes the splitting of phosphatidyl-inositol-4,5-bisphosphate into its hydrophobic and hydrophilic components in the cell membrane. There are three subfamilies, beta, gamma, and delta, and each subfamily has two to four isoforms. All the isoforms have a X and a Y region, a pleckstrin homology domain near the amino-terminal ends, and a C2 domain near the carboxyl-terminal ends.

C-H activation

Article Abstract:

The invention of processes to activate the generally unreactive carbon-hydrogen (C-H) bonds in hydrocarbons could enable an understanding of the full potential of the inert hydrocarbons. The various steps in the activation and the hurdles in the process are discussed, also discussing the possible consequences and uses of the activation of the C-H bonds.
