Fenretinide(4HPR) is an inhibitor of Focal adhesion kinase (FAK) [1].

Fenretinideis a vitamin A analogue, it has been shown toinhibit the growth of many tumor cells, including small-cell lung cancer, malignant hemopoietic cells, and breast cancer cells. Fenretinide may also protectwomen against the development of ovarian cancer. The effect of Fenretinide on several gynecologic cancer cell lines shows the IC50 values of Fenretinide are only 0.3 and 0.4μM in two ovarian cancer cell lines(222and UCI 101) and are from 1 to 10μM in other ovarian cancer cell lines and cervical, endometrial cancer cell lines [2].

Fenretinide has also been shown to induce apoptosis inhuman prostate carcinoma cells (HPC).The IC50s of Fenretinide in LNCaP, DU145, and PC-3 are 0.9±0.16μM, 4.4±0.45μM and 3.0±1.0μM,respectively.Fenretinide induces this apoptosis through increasingROS and increasing enzymatic labeling of DNA breaks and formation of a DNA ladder. It is also reported that Fenretinide can impair prostate cancer cell migration and invasion by interfering with FAK/AKT/GSK3β pathway and β-catenin stability [1, 3].
