DPPE-MPEG(2000) is a polyethylene glycol (PEG) derivative of 1,2-dipalmitoyl-rac-glycero-3-phosphoethanolamine (DPPE), characterized as a PEGylated phospholipid.

DPPE-mPEG, a PEG-modified lipid, minimizes nonspecific protein adsorption and extends circulation time in vivo [1].

1,2-Dipalmitoyl-sn-glycero-3-PE-N-(cap biotin) is a biotinylated phospholipid. It has been used in PEGylated polyamidoamine-dendrimer-conjugated supported lipid bilayers (SLB) to isolate circulating tumor cells and tumor cell microembolis from patient-derived blood by antibody-coated microfluidics. [1] It has also been used as a component of SLBs to detect protein-ligand binding with ortho-conjugated Texas Red DHPE. [2] In addition, 1,2-dipalmitoyl-sn-glycero-3-PE-N-(cap biotin) has been used in SLBs partitioned into nanowells to create DNA curtains, which can be used as a high-throughput tool for detection of protein-DNA interactions at the single molecule level.[3]

Tesmilifene fumarate (DPPE fumarate) (DPPE fumarate) is an H1C receptor antagonist。

1,3-Dipalmitoyl glycero-2-phosphatidylethanolamine is a phospholipid incorporating saturated long-chain (16:0) stearic acid at the sn-1 and sn-3 positions, with phosphatidylethanolamine (PE) at the sn-2 position. Phosphatidylethanolamines, critical components of biological membranes, play essential structural and functional roles. Various PE types are instrumental in forming micelles, liposomes, and other synthetic membranes.

1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE), a phospholipid member of the glycerophosphonoethanolamine family, is a major component in biological membranes. Studies focused on interactions between DPPE and cholesterol show that cholesterol induces condensation of DPPE monolayers in the presence of Ca2+ ions. Membranes containing a higher concentration of this compound contain more ordered lipid tails which result in a thicker membrane.

1,2-Dipalmitoyl-13C-sn-glycero-3-PC is intended for use as an internal standard for the quantification of 1,2-dipalmitoyl-sn-glycero-3-PC by GC- or LC-MS. 1,2-Dipalmitoyl-sn-glycero-3-PC (DPPC) is a zwitterionic glycerophospholipid commonly used in the formation of lipid monolayers, bilayers, and liposomes for use in a variety of applications.1,2,3,4 It has been used in the formation of proteoliposomes for implantation of γ-glutamyl transpeptidase into human erythrocyte membranes.3 Incorporation of glycosphingolipid antigens into DPPC-containing liposomes increases the immunogenicity of the antigens in mice.4 |1.

1-Palmitoyl-d9-2-palmitoyl-sn-glycero-3-PE serves as an internal standard for the quantification of 1,2-dipalmitoyl-sn-glycero-3-PE (1,2-DPPE) using GC- or LC-MS. 1,2-DPPE, a prevalent PE (phospholipid), contains C16:0 fatty acids at the sn-1 and sn-2 positions and is essential in the inner plasma membrane leaflet. This compound forms a condensed lipid monolayer with cholesterol through tight hydrogen bonding between 1,2-DPPE headgroups, enhancing membrane fluidity to support transport and signaling.

1,2-Dipalmitoyl-sn-glycero-3-N,N-dimethyl-PE is a derivative of 1,2-dipalmitoyl-sn-glycero-3-PE (1,2-DPPE) with two added methyl groups on its sn-3 moiety, which in aqueous suspensions, reduces the phase transition temperature relative to those of 1,2-DPPE and 1,2-dipalmitoyl-sn-glycero-3-N-methyl-PE (1,2-NMeDPPE). It is utilized in creating liposomes and monolayers for investigating membrane permeability and monolayer viscosity.
