A hydrogen-transfer strategy for the catalytic functionalization of benzylic alcohols via electronic arene activation, accessing a diverse range of bespoke diaryl ethers and aryl amines in excellent isolated yields (38 examples, 70% average yield), is reported. Taking advantage of the hydrogen-transfer approach, the oxidation level of the functionalized products can be selected by judicious choice of simple and inexpensive additives.

The tandem isomerization and nucleophilic aromatic substitution of allylic fluoro-substituted benzylic alcohols is described for the first time. In the presence of the ruthenium complex Ru(PPh3)3(CO)(H) 2, 1-(4-fluorophenyl)prop-2-en-1-ol is converted into the corresponding para-amino ketone or para-phenolic substituted ketone. Copyright

A series of 5-phenyl-substituted-N-alkyl-imidazolin-2-ones with potent radical-scavenging activity and lipid peroxidation inhibitory activity was synthesized. Many of the compounds showed memory-improving effect in animal models independent of the inhibitory activity on lipid peroxidation.
COMPOUND FOR INHIBITING TYROSINE KINASE ACTIVITY OF DDR2 PROTEIN
-
Page/Page column 29-31, (2010/02/14)
A new furopyrimidine compound, their pharmaceutically acceptable salt, and a tyrosine kinase activity inhibitor. The furopyrimidine compound is a compound defined by chemical formula 1, 2, 3 or 4, on their precursor, and can exist as a form of free base or in an acid-addition salt. Since the furopyrimidine compound has an effect of inhibiting activity of DDR2 tyrosine kinase, it can be used in treating illnesses caused by the DDR2 tyrosine kinase activity such as hepatocirrhosis, rheumatoid arthritis or cancer.
(Aryloxy)aryl semicarbazones and related compounds: A novel class of anticonvulsant agents possessing high activity in the maximal electroshock screen

A number of (aryloxy)aryl semicarbazones and related compounds were synthesized and evaluated far anticonvulsant activities. After intraperitoneal injection to mice, the semicarbazones were examined in the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ), and neurotoxicity (NT) screens. The results indicated that greater protection was obtained in the MES test than the scPTZ screen. Quantitation of approximately one-third of the compounds revealed an average protection index (PI, i.e. TD50/ED50) of approximately 9. After oral administration to rats, a number of compounds displayed significant potencies in the MES screen (ED50 of 1-5 mg/kg) accompanied by very high protection indices. In fact over half the compounds had PI figures of greater than 100, and two were in excess of 300. The compounds were essentially inactive in the scPTZ and NT screens after oral administration to rats. Various compounds displayed greater potencies and PI figures in the mouse intraperitoneal and rat oral screens than three reference clinically used drugs. The data generated supported a binding site hypothesis. Quantitative structure-activity relationships indicated a number of physicochemical parameters which contributed to activity in the MES screen. X-ray crystallography of five compounds suggested the importance of certain interatomic distances and bond angles for activity in the mouse and rat MES screens.
