FC 11 is a highly potent focal adhesion Ki nase (FAK) PROTAC®Degrader (DC50 values are 40 to 370 pM depending on cell line), which is composed of the FAK inhibitor PF 562217 joined by a linker to the cereblon-binding ligand Pomalidomide. The effects of FC 11 are reversible upon compound wash out. FC 11 also degrades autophosphorylated FAK (pFAKtyr397), displaying near complete degradation after 3 hours at 100 nM in TM3 cells.
PAF C-18:1 is a naturally occurring phospholipid produced by cells upon stimulation and plays a role in the establishment and maintenance of the inflammatory response. It is less potent than PAF C-16 and PAF C-18 in the induction of neutrophil chemotaxis, but is equipotent to PAF C-16 and PAF C-18 in promoting eosinophil migration. PAF C-18:1 activates the PAF receptor and has been used in antibody binding experiments to determine the importance of an acyl linkage at the sn-2 position for recognition at this receptor.
PAF C-16 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the remodeling and 'de novo' pathways. It is a potent mediator of neutrophil migration and the production of reactive oxygen species and IL-6. Pathological processes involving PAF include necrotizing enterocolitis
2-O-methyl PAF C-16 is a synthetic analog of platelet-activating factor (PAF) featuring a methyl group attached via an ether linkage at the sn-2 position. While the specific biological activities of 2-O-methyl PAF C-16 remain undercharacterized, studies with its C-18 counterpart have demonstrated its ability to modulate various biological processes. These processes include reducing plasma membrane fluidity and hindering the invasiveness of tumor cells in embryonic chick hearts. Furthermore, in rat astrocytes, the C-18 analog prompts the release of significant amounts of nitric oxide (NO) through a mechanism that involves the activation of nitric oxide synthase (NOS).
