Butamirate citrate is an anti-tussive which may be used in the treatment of non-productive (dry) cough.

Butamirate, particularly Butamirate citrate, is a cough suppressant that works by acting centrally through the receptors in the brainstem. It has a very beneficial effect, because it reduces the resistance in the airways by inhibiting bronchospasm and anti-inflammatory effect.

Biotin-PEG6-Maleimide is a PEG derivative containing a biotin group and a maleimide group for labeling and crosslinking cysteines and other sulfhydryls. The maleimide group reacts specifically with sulfhydryl groups (at pH 6.5-7.5) to form a stable, irreversible thioether linkage. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules.

The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

Fluorescein-PEG3-Amine is a fluorescein dye with excitation/emission maximum 494/517 nm containing a free amine group, which can be reactive with carboxylic acid, activated NHS ester, carbonyl (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding.

PEG4-bis(phosphonic acid diethyl ester) is a PEG Linker.

t-Boc-Aminooxy-PEG4-Tos is an Aminooxy PEG Linker. Aminooxy-PEG can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage.

3,4-Dibromo-Mal-PEG2-Boc-Amine is a PEG Linker.

Mal-PEG5-NHS ester is a PEG derivative containing a maleimide group and an NHS ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

Hydroxy-PEG3-PFP ester is a PEG derivative containing a hydroxyl group with a PFP ester group. It can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. PFP esters have similar applications as the NHS esters, but are more stable in aqueous solution.
