activity in cyclohexene oxidation (TOF = 72 h(-1)) were detected. Partial retention of configuration (RC = 53%) in cis- and trans-1,2-dimethylcyclohexane oxidation, moderate 3 degrees/2 degrees selectivity (4.1) in adamantane oxidation, and the observation of a relatively high kinetic isotope effect for cyclohexane oxidation (KIE = 3.27) suggest partial metal-based oxidation, probably in tandem with free-radical
Aurora kinase A inhibitors: Identification, SAR exploration and molecular modeling of 6,7-dihydro-4H-pyrazolo-[1,5-a]pyrrolo[3,4-d]pyrimidine-5,8-dione scaffold
Tricyclic 6,7-dihydro-4H-pyrazolo[1,5-a]pyrrolo[3,4-d]pyrimidine-5,8-dione was identified as a novel scaffold for Aurora kinase A inhibition through virtual screening. SAR exploration coupled with molecular modeling of 8a reveals the minimum pharmacophore requirements for Aurora kinase A inhibition. (c) 2008 Elsevier Ltd. All rights reserved.

Anthracene-based, H(+)-driven, 'off-on-off' fluorescent PET (photoinduced electron transfer) switches. are immobilized on organic and inorganic polymeric solids in the form of Tentagel(R) and silica, respectively. The environment of the organic bead displaces apparent switching thresholds towards lower pH Values whereas the Si-O(-) groups of silica electrostatically cause the opposite effect. These switches are ternary logic gate tags, one of which can be particularly useful in Strengthening molecular computational identification (MCID) of small solid objects. (C) 2008 Elsevier Ltd.
