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.

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

PRESSURE+ Declaration of Conformity

Certificates

Biotage® PRESSURE+ manifolds deliver positive pressure, parallel processing for 96 well plates, 1 mL 3 mL and 6 mL column formats. The systems utilize a consistent, uniform flow of positive pressure to move both low and high viscosity liquids through SPE plates and columns. Each port of the PRESSURE+ manifold independently maintains constant pressure, increasing the overall reproducibility of analyte recoveries. This unique design allows for partially populated racks to be used without sacrificing extraction efficiency.

PS-DMAP is a polymer-bound equivalent of dimethylaminopyridine (DMAP) which may be used as a catalyst for acylation and related reactions. PS-DMAP has a loading of 1.4 mmol/g based on nitrogen analysis. Typical catalysis conditions require 10 - 20 mol% relative to the nucleophile. Catalytic PS-DMAP accelerates the acylation of sluggish nucleophiles, e.g. tertiary alcohols.

PS-TBD (Figure 1) is a polystyrene bound guanidine base, which is stronger than corresponding resin bound DIEA (DIPEA) and bound N-Methyl-morpholine resins. It has a wide variety of uses in synthesis, from direct alkylation through to sequestering of acidic components of reaction.

An oxidation method using a novel solid phase oxidant, based on a covalently polystyrene bound, sulfonic ester linked 2,2,6,6-tetramethylpiperidine-1-oxyl species is presented, PS-TEMPO (Fig.1a&1b).1,2 The reagent showed fast room temperature kinetics compared to similar known systems3 when used to oxidize primary and secondary alcohols to aldehydes and ketones, respectively (Table 1). The products were in general of high purity and the isolated yields were good to excellent. The used reagent could be reactivated and reused for multiple oxidation reactions. The colour change observed as the oxidation state of the reagent changed, gave an indication of the extent to which the reagent had been used.

PS-Thiophenol is based on an aminomethyl resin with a tethered thiophenol functionality. The resin was designed for the scavenging of alkylating agents, e.g. alkyl halides. PS-Thiophenol was tested and found effective in scavenging alkylating agents ranging from octyl bromide to benzyl bromide. The scavenging effectiveness of PS-Thiophenol was found to be greater than a polymer-bound benzyl thiol towards octyl bromide, indicative of the higher nucleophilicity of the thiophenolate.

PS-Triphenylphosphine is a resin-bound equivalent of triphenylphosphine. The capacity of the resin is determined by the quantitation of benzyl bromide uptake in DMF (GC, internal standard method).

PS-Trisamine is an amine functional resin for the removal of excess electrophilic reagents during the quenching and purification of reaction mixtures.1 PS-Trisamine resin has a scavenging capacity of 3.0–4.0 mmol/g based on reaction with an excess of benzoyl chloride. Scavenging of common electrophiles typically requires 3–6 equiv of PS-Trisamine and occurs within 0.5–3 h at room temperature. The scope of PS-Trisamine as a scavenger for electrophilic reagents was investigated using 4-chlorobenzoyl chloride, 2-phenylbutyryl chloride and 2,6-dimethoxybenzoyl chloride as a series of acid chlorides with decreasing reactivity.Acid chlorides were completely scavenged in 0.5 h using 3.5 equiv PS-Trisamine (Table 1). The presence of a tertiary base, e.g. PS-DIEA or PS-NMM, reduces the amount of PS-Trisamine required in the reaction by removing the hydrogen chloride formed. In addition to acid chlorides, benzenesulfonyl chloride and 4-methoxyphenyl isocyanate were effectively scavenged in 0.5 h.
