Biological Activity

m-PEG9-Amine is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1] . In Vitro: ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.

1.HDL functionality in South Asians as compared to white Caucasians.

BACKGROUND AND AIMS: South Asians have an exceptionally high risk of developing cardiovascular disease compared to white Caucasians. A contributing factor might be dysfunction of high density lipoprotein (HDL). We aimed to compare HDL function in different age groups of both ethnicities.

Zha YJ1, Jiang XY1, Gong MQ1. Beijing Da Xue Xue Bao. 2016 Apr 18;48(2):224-9.

OBJECTIVE: To introduce the surgical techniques and treating results of the old "terrible triad" of the elbow.

3.Impact of a systems engineering intervention on PMTCT service delivery in Côte d'Ivoire, Kenya, Mozambique: a cluster randomized trial.

Rustagi AS1, Gimbel S, Nduati R, Cuembelo MF, Wasserheit JN, Farquhar C, Gloyd S, Sherr K; with input from the SAIA Study Team. J Acquir Immune Defic Syndr. 2016 Apr 14. [Epub ahead of print]

BACKGROUND: Efficacious interventions to prevent mother-to-child HIV transmission (PMTCT) have not translated well into effective programs. Prior studies of systems engineering applications to PMTCT lacked comparison groups or randomization.

4.Comparison of mid-term haemodynamic performance between the BioValsalva and the BioIntegral valved conduits after aortic root replacement.

OBJECTIVES: We retrospectively compared the haemodynamic performance of the BioValsalva (BV) and BioIntegral (BI) biological aortic-valved conduits in the aortic root position.

mPEG9-amine is an amine-terminated methoxy poly(ethylene glycol) building block designed to introduce a hydrophilic, flexible PEG spacer into PROTAC constructs. Its ether-rich backbone can improve aqueous solubility and reduce nonspecific interactions, while the terminal primary amine enables efficient conjugation to ligands or linker fragments used in targeted protein degradation workflows. The following sections describe its structural features and practical reactivity considerations in PROTAC assembly.

Structure: mPEG9-amine comprises a methoxy-terminated poly(ethylene glycol) chain capped with a primary amine. The molecule is dominated by ether linkages along the PEG backbone, with a terminal C–N bond defining the reactive handle. This architecture yields a flexible, highly solvated, hydrophilic polymer-like scaffold.

Reactivity: The terminal primary amine is suitable for standard amide or urea formation with activated carboxylic acids or isocyanates, and for carbamate formation using activated carbonyl reagents. Typical PROTAC linker coupling strategies employ coupling reagents such as carbodiimides with additives, or acyl chlorides/activated esters under anhydrous or buffered conditions. Polar aprotic solvents and controlled pH help maintain amine nucleophilicity while minimizing PEG degradation and side reactions.
