A series of eight 3-alkylidylindolin-2-ones were conveniently synthesized on Biotage® Endeavor™ in high yield and purity. Reactor purging, agitation, pressurization, heating, gas uptake and run termination were performed automatically based on the run program.
Biotage has developed a range
of tools to improve the peptide synthesis workflow,
from synthesis of crude peptides through to the final
purified product. These solutions make your workflow
more efficient and improve the quality of peptides
you synthesize. Our workflow solutions are used in
pharma, biotech, CRO and academic laboratories

Dr. Andrew Jamieson leads a team of peptide chemists at the University of Glasgow, where
they synthesize complex molecules for chemical biology applications. An important tool that
contributes to their success has been Biotage® Initiator+ Alstra™ microwave peptide synthesizer,
and they are even breaking the dogma that only HPLC can be used for peptide purification, by
using cutting edge reversed phase flash purification techniques provided by Biotage.

Sample preparation is an essential technique prior to LC-MS/MS analysis of drugs in biological fluid samples to remove unwanted matrix components. These matrix components, particularly salts, proteins and phospholipids, can lead to ion suppression resulting in inaccurate quantitation and reduced detection limits. Resin-based mixed-mode cation exchange SPE sorbents are widely used for the extraction of basic compounds from biological fluids. The dual retention mechanism allows a two stage interference wash protocol, which results in extremely
clean extracts. This poster investigates the performance of EVOLUTE™ CX for overall ion suppression, then individual matrix components examined in terms of protein and phospholipid removal.

PS-HOBt(HL) is a higher loading version (0.9 – 1.4 mmol/g) of a sulfonamide-linked,
resin-bound equivalent of 1-hydroxybenzotriazole (HOBt). PS-HOBt(HL) can be used as an effective activating reagent for transfer of protecting groups, e.g., Fmoc and Cbz, to amines.

PS-TBD is a polymer-supported base, which
consists of a bicyclic guanidine moiety (1,5,7-
triazabicyclo[4.4.0]dec-5-ene) anchored on
polystyrene. PS-TBD is a stronger polymersupported
base than the PS-DIEA and PS-NMM
resins, which are bound tertiary amines that are
used in organic synthesis and reagent
scavenging. Published applications of PS-TBD
include alkylation of phenolsi and amines;ii
esterification of carboxylic acids using alkyl
halides; alkylation of activated methylene
compounds; de-halogenation of organic
halides;iii high throughput synthesis of aryl
triflates and aryl nonaflates,iv and the
regioselective synthesis of lysophospholipids.

PS-DEAM is a polystyrene-bound diethanolamine, which is a resin-bound equivalent of the tridentate (N, O, O) N-alkyldiethanolamine ligand. PS-DEAM is an effective scavenger for a variety of oxophilic organometallic and inorganic complexes. The resin can be used to quench reactions and remove metallic reagents, catalysts or byproducts, allowing the purified product to be isolated by filtration. Boronic acids are scavenged by PS-DEAM. This has been exploited in the purification of Suzuki reactions through the removal of excess boronic acid and coupling byproducts.

MP-Borohydride is a macroporous, polystyrene-bound borohydride, that is a resin-bound equivalent of tetraalkylammonium borohydride. The bound borohydride is a versatile reducing agent1,2,3 used for the reduction of carbonyl compounds and imines, and the reductive amination of aldehydes and ketones. The resin, in conjunction with some transition metal salts, can also be used for a number of other important reductive applications, such as reduction of oximes,
azides and alkyl halides. The reduced products are isolated by simple filtration away from the resin.

Oral fluid is of increasing importance as a biological
matrix in drugs of abuse and related analyte testing
because of the ease of sample collection, and
difficulty in adulteration of samples, particularly
when compared with urine.

The automated Advantage Series™ 3400 ChemCorder™ workflow replicator was used to record all the manual operations a chemist performs during a highly exothermic chemical reaction (Figure 1).Before the experiment was initiated, the ChemCorder replicator was put in record mode.All steps of the experiment were accurately recorded, including any comments and observations. Once completed the ChemCorder replicator produced a report and recipe file of the chemistry. This recipe file was used to accurately and automatically repeat the reaction. Alternatively, the file could have been modified to produce a new recipe based on the recorded chemistry
