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
