Nucleoside chemistry is traditionally labor intensive and the output of compoxmds is consequently relatively low. In order to overcome these limitations, several groups have implemented a parallel or combinatorial approach to speed up the synthesis process this chapter will only discuss the use of solid support for the synthesis of nucleoside libraries, not for the piupose of oligonucleotide synthesis. Chang <05BMC4760> attached a purine diehloride to a Merrifield 3,4-dihydropyran resin, followed by sequential displacement of the two ehloro atoms by various amines. The purine heterocyclic bases were then condensed with Dd.-ribofuranosides following a classical Vorbruggen method to yield nucleosides of general formula 171. 

The work presented here was aimed at establishing the influence of different alkali metal cations on the distribution of silicate anions in aqueous solutions such as those used in zeolite synthesis. Changes in the extent of silicate oligomerization were identified...

In contrast to endurance exercise, acute whole-body resistance exercise does not alter leucine oxidation. In this same study we also did not find an effect of acute resistance exercise on whole-body protein synthesis, either during exerdse or for up to 2 h post-exerdse. We hypothesized that since muscle protein synthesis (MPS) accounted for only 25% of whole-body synthesis, changes in MPS either may be not measurable or would be negated by a redprocal change in the synthesis of another protein, such as one in the gastrointestinal tract. 

Disadvantages of the synthesis of DNA copolymers without a synthesizer are less convenience and more time consumption but this type of method is especially helpful in the case of solvent or catalyst incompatibilities. The conditions of post-DNA synthesis change depending on factors such as chemo-stability, catalyst and... 

One other synthesis change was to use 7V-isobutyryl-protected deox-ycytidine, instead of the more commonly used 7V-benzoyl-protecting group. This change is necessary because the improved deprotection conditions described below generate transamination side products with benzoylated cytosine, but not with isobutyryl-protected cytosine (14). The isobutyryl-protected dC monomer and the corresponding isobutyryl-protected dC DNA synthesis support can be obtained from JBL Scientific (San Luis Obispo, CA).
