MedKoo CAT#: 556014

CAS#: 1849616-42-7

Description: ALC-0159 is a PEG/lipid conjugate (i.e. PEGylated lipid), specifically, it is the N,N-dimyristylamide of 2-hydroxyacetic acid, O-pegylated to a PEG chain mass of about 2 kilodaltons (corresponding to about 45-46 ethylene oxide units per molecule of N,N-dimyristyl hydroxyacetamide). It is a non-ionic surfactant by its nature. It has been deployed in the Pfizer-BioNTech SARS-CoV-2 mRNA vaccine that contains the active ingredient tozinameran.

Bulk inquiry Welcome, Customer: Please do not inquire quote if your intended use is for a patient since our products are for research use and for chemical synthesis use, not for human use . For in-stock products, we listed price in the web page. You may inquire prices for which sizes were not listed. If no price is listed, this means the product is not in stock at the moment, which may be available via custom synthesis. For cost-effective reason, minimum order of 1g is requested (typically very expensive). The lead time is usually 2-4 months. Quote of less than 1g will not be provided. MedKoo may not offer quote for below reasons: (1) current available synthetic method appears to be extremely expensive which is obviously not affordable to most customers; (2) Key raw material to make the product is temporally not available; (3) DEA controlled substances; (4) the product is under patent protection in customer’s country.

Biological target:	ALC-0159 is a polyethylene glycol (PEG) lipid conjugate that could be used as vaccine excipient.
In vitro activity:	ALC-0315 is an ionisable aminolipid that is responsible for mRNA compaction and aids mRNA cellular delivery and its cytoplasmic release through suspected endosomal destabilization. The LNPs in the Pfizer-BioNTech COVID-19 vaccine contain low levels (<2 mol %) of ALC-0159, which contributes to nanoparticle stabilization by a steric mechanism through its poly(ethylene glycol) (PEG) moiety. Considering their low ALC-0159 content, LNPs in the Pfizer-BioNTech COVID-19 vaccine most likely display a weak steric barrier of PEG.
