The work we are doing with Mast is one example of our collaborations with pharmaceutical companies to develop high purity poloxamers for a variety of applications for the pharmaceutical and biotechnology value chains, said Daniele Piergentili, Head of Global Marketing and R&D, BASF Pharma Ingredients and Services.
In recent years, the advanced technologies have been used which include hydrogels, [sup][8] nanoparticles, [sup][9] and poloxamers.
Poloxamer 407 is a hydrophilic nonionic surfactant that belongs to a class of copolymers called poloxamers.
However, poloxamers have shown to incorporate into the cellular membranes, particularly of the cancerous cells, affecting so the microviscosity of the cell membrane.
For example, poly-N-isopropylacrylamide becomes insoluble at about 37[degrees]C, hydroxypropyl cellulose separates at temperatures above about 40[degrees]C and poloxamers gel once the temperature reaches the lower critical solution temperature (LCST).
Our options for adjuvants in future vaccines also include proven cationic lipids such as DMRIE/DOPE, which has demonstrated excellent safety in our cancer studies; poloxamers, which have demonstrated both safety and utility as vaccine adjuvants; and of course, alum, which is commonly used as an adjuvant in conventional vaccines.
