Oligoribonucleotides with 2'-5' linkages have been synthesized on solid support. UV melting and CD experiments indicate complementary strands associate to give complexes with melting temperatures 30 to 40 degrees C lower than for duplexes formed by 3'-5' oligoribonucleotides with the same sequence. UV melting and imino proton NMR spectra and NOEs for (2'-5') CGGCGCCG are consistent with formati...

As the scale of the microarray experiments increases, a single oligo nucleotide array is no longer large enough. Therefore, the use of multiple oligo arrays for one experiment becomes more important. The design and synthesis of multiple arrays to minimize the overall synthesis cost is an interesting and important problem. We formulate the multiple array synthesis problem (MASP) that deals with ...

D2.2.5.1 Abstract MineSetTM is a commercial data mining product from Silicon Graphics. It provides an interactive platform for data mining, integrating three powerful technologies: database and file access, analytical data mining engines, and data visualization. MineSet supports the knowledge discovery process from data access and preparation through iterative analysis and visualization to depl...

In the title 1,3,2-dioxaphospho-rinane derivative, C(10)H(11)Br(2)O(4)P, the 1,3,2-dioxaphospho-rinane ring adopts a chair conformation, having the P=O bond equatorially oriented and the phen-oxy group axially oriented. The bromo substituent is in an axial position opposite to the phen-oxy group and the bromo-methyl group is in an equatorial position opposite to the P=O bond. In the crystal pac...

In the 5-chloro-salicylate anion of the title salt, C6H9N2(+)·C7H4ClO3(-), an intra-molecular O-H⋯O hydrogen bond with an S(6) graph-set motif is observed and the dihedral angle between the benzene ring and the -CO2 group is 1.6 (6)°. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, form...

In the title compound, C(16)H(26)O(5)S, the oxathiol-ane ring adopts an envelope conformation, with the S atom 0.793 (3) Å out of the mean plane of the remaining four atoms. The cyclo-hexane ring of the menthol fragment adopts an almost ideal chair conformation, with all substituents in the equatorial positions. In the crystal, relatively strong, short and linear C-H⋯O hydrogen bonds link the m...
