Learn More

D(+)-Raffinose pentahydrate is an orally active inhibitor of LecA (Kd = 32 μM) and GtfC. It functions by reducing cyclic diguanylate (c-di-GMP) through increased activity of a c-di-GMP specific phosphodiesterase and interferes with GTF function. This compound decreases IL-4 and IL-5 mRNA, exhibits biofilm-inhibitory activity against *Pseudomonas aeruginosa* and *Streptococcus mutans*, and inhibits allergic airway eosinophilia. It is intended for research use only and not for sale to patients.

Learn More

Propargyl-PEG1-SS-PEG1-t-butyl ester is a cleavable PEG-based linker containing terminal propargyl (alkyne) groups and a disulfide bond. It is used in bioconjugation workflows such as antibody-drug conjugate and PROTAC synthesis, and as a click-chemistry handle for azide-alkyne cycloaddition.

• Cleavable disulfide linkage allows intracellular reduction and payload release.
• Terminal propargyl groups enable copper-catalyzed and strain-promoted click reactions.
• High purity (>98.0%) suitable for synthetic chemistry applications.
• Molecular weight 320.47 g/mol and formula C14H24O4S2.
• Available in small research quantities (5 mg, 10 mg, 25 mg) for lab-scale synthesis.
