ABSTRACT
PTEN (phosphatase and tensin homologue deleted on chromosome 10) is well known as a tumour suppressor. It's PI(3,4,5)P3 lipid phosphatase activity is an important counteracting mechanism in PI 3-kinase (phosphoinositide 3-kinase) signalling. Furthermore, PTEN lies upstream of Akt kinase, a key enzyme in insulin signalling regulating glucose uptake and cell growth. Therefore, PTEN has recently gained attention as a valuable drug target for the treatment of diabetes, stroke, cardiac infarct and fertility. This review summarizes the use of small molecules as PTEN inhibitors. Currently available methodologies and techniques for accessing PTEN inhibition in vitro and in cellulo will be discussed.
