Journal written in English. CAN 131:144536 AN 1999:369513 CAPLUS (Copyright (C) 2009 ACS on SciFinder (R)) Abstract The synthesis of a new series of potent 2-oxy-3-arylpropanoic acid antihyperglycemic agents in both racemic and non-racemic form is described. (the biol. activity of these compds. was not reported here). Resoln. of racemic acids is accomplished via amide formation with either (S)-2-phenylglycinol or (S)-4-benzyl-2-oxazolidinone as complementary resolving agents. The target compds. were ?-alkoxy-4-[2-[(2-benzoxazolyl)amino]ethoxy]benzenepropanoic acid derivs.

Facile biocatalytic reduction of the carbon-carbon double bond of 5-benzylidenethiazolidine-2,4-diones. Synthesis of ( )-5-(4-{2-[methyl(2-pyridyl)amino]ethoxy}benzyl)thiazolidine-2,4-dione (BRL 49653), its (R)-(+)-enantiomer and analogs.

CAN 122:105736 AN 1995:237497 CAPLUS (Copyright (C) 2009 ACS on SciFinder (R)) Abstract A novel biotransformation system for the redn. of carbon-carbon double bonds in 5-benzylidenethiazolidine-2,4-diones to give the corresponding 5-benzylthiazolidine-1,4-diones, using whole cells of red yeasts, is described. These reduced compds., which are recovered in good yield, are of potential use in the treatment of non-insulin dependent diabetes mellitus. The mild reaction conditions developed allow redn. of 5-benzylidenethiazolidine-2,4-diones contg. other functionalities which are not compatible with alternative redn. methods. The biocatalytic redn. is enantioselective and the synthesis of R-(+)-5-(4-{2-[methyl(2-pyridyl)amino]ethoxy}benzyl)thiazolidine-2,4-dione by Rhodotorula rubra CBS 6469 and structure confirmation by X-ray crystallog. is detailed. Optimization of reaction conditions (including immobilization) for these whole cell redn. system is described.

Eochaid ua Flainn is Eochaid ua Flannucáin: Súil Úr ar an bhFianaise

The evidence for two poets on record in the tenth century is reconsidered. The argument is made that they can be identified as one person, the poet Eochaid ua Flannucáin, a member of the religious community of Armagh and founder of a dynasty which governed the centre of the Irish church for over 150 years.

Intellectual Property management in publicly funded R&D centres—A comparison of university-based and company-based research centres

Recent thinking on open innovation and the knowledge-based economy have stressed the importance of external knowledge sources in stimulating innovation. Policy-makers have recognised this, establishing publicly funded Centres of R&D Excellence with the objective of stimulating industry–science links and localised innovation spillovers. Here, we examine the contrasting IP management practices of a group of 18 university- and company-based R&D centres supported by the same regional programme. Our analysis covers all but one of the Centres supported by the programme and suggests marked contrasts between the IP strategies of the university-based and company-based centres. This suggests the potential for very different types of knowledge spillovers from publicly funded R&D centres based in different types of organisations, and a range of alternative policy approaches to the future funding of R&D centres depending on policy-makers’ objectives.
