<P>Four novel secondary metabolites possessing a unique 6/5/5 tricyclic ring system, streptoglycerides A-D (<B>1</B>-<B>4</B>), were isolated from a marine actinomycete <I>Streptomyces</I> sp. derived from a mangrove sample collected on Kosrae Island. Their structures and absolute configurations were elucidated by spectroscopic data and electronic circular dichroism data. Streptoglyceride C (<B>3</B>) showed a weak inhibitory effect on the production of nitric oxide in BV-2 microglia cells.</P> [FIG OMISSION]</BR>

<P>Two new glycosylated alkylresorcinols, resorcinosides A (<B>1</B>) and B (<B>2</B>), were isolated from a strain of the fungus <I>Penicillium janthinellum</I> derived from a marine sediment sample collected from Cu Lao Cham Island, Vietnam. The structures of <B>1</B> and <B>2</B> were established by interpretation of 1D and 2D NMR and high-resolution ESIMS data, and their absolute configurations were confirmed by the coupling constant of the anomeric proton, acid hydrolysis, subsequent HPLC analysis, Mosher’s method, and quantum-mechanics-based computational analysis of NMR chemical shifts. The structure elucidation indicated that <B>1</B> and <B>2</B> are new alkylresorcinols with <SMALL>D</SMALL>-glucose, and <B>2</B> has an α-pyrone moiety attached to the aromatic ring. Compound <B>1</B> exhibited cytotoxic activity against the NUGC-3 cancer cell line with a GI<SUB>50</SUB> value of 9.3 μM.</P> [FIG OMISSION]</BR>

The main object of this study is to propose strategic model which can integrate U-Construction strategy and U - IT839, and we would present exclusive U-Construction strategy and it's resonable course model in construction industry comparing with advance direction of Information technology. Recently, leading power in U-City Construction market has been preoccupied by IT corporations, and associated R & D is being promoted by IT industry, so Construction corporations still can't participate in U-City Construction market. In order to solve this problem, specific breakdown structure of Construction Industry must be established and the strategy by which IT can be managed integrately must be also be established. Based on these, in this paper we would present Strategy for U-Project by suggesting U-Construction Strategic Model.
