Histone deacetylases are the enzymes which work to transform the normal cells to tumor cells by activating different oncogenic pathways in the cells. Droxinostat is an inhibitor of these HDACs enzymes. Research studies have shown that the cancers can be control by modulating the activity of these HDACs. To control the cancerous growth of cells different inhibitors to these histone deacetylases have been devised which control the progression of cancers. FTY720 is one of strong inhibitor present in compound library of HDAC inhibitors which make the cancerous cells sensitive and susceptible to death inducing ligands. Droxinostat works against the apoptosis inhibitors and causes the cell death. Two important death causing ligands are TRAIL and Fas which activates the caspase pathways of apoptosis by binding to death receptors in normal cell lines. Some type of malignancies are related to hindrance caused by malignant cells in binding of these ligands to the death cell receptors as some malignant cells offered resistance to these ligand molecules. Anoikis is a specific kind of cell death which occurs when a break up from extra cellular matrix takes place. This mechanism of cellular death even occurs in the above mentioned situation. Scientists made a lot of research to identify such molecules which FTY720 can make the tumor cells sensitive to death signals. The first such ligand to be identified was Fasentin. It causes the cell death in cancerous cell lines by making the cells sensitive to TRAIL and FAS ligands. However how it works was unclear. It was revealed later that it has a strong control on the genes regulating the glucose and nutrient uptake. The down-regulation of these genes causes the inhibition of glucose uptake as a result of which cell became strived ultimately leading to cell death. Transport of glucose within the cells across its cell membrane is controlled by a transport protein named GLUT 1. GLUT1 maintains a particular intracellular channel and controls the glucose transport while the fasentin molecule affects this channel at a particular site and blocks it. From same screening library, it was identified that Vorinostat and droxinostat has enough potential as a HDAC inhibitor to decrease in levels of FLIP protein. Caspase 8 is a protein also named as FLIP. The decrease in its levels causes the sensitization of cancerous cells towards death stimulating ligand TRAIL. TRAIL activates the pathways of apoptotic cell death and stimulates selective killif tumor cells. In case of pancreatic carcinoma, this has been proved an efficient mechanism. Droxinostat causes the decrement in mRNA levels of FLIP protein and stimulates the process of anoikis i.e. disconnect of cells FTY720 with extracellular matrix. Hence it becomes able to stop the tumor progression by inhibiting the metastasis in cancers and don’t allow to produce cancerous growth even at a far location. HDAC inhibitors are responsible of playing various roles like stimulation of cellular differentiation, cellular death and preparing the cells to susceptible for pro-death stimulations. The apoptotic FTY720 cell death induced by some inhibiting molecule can cause modulations in different genes which control the pathways for apoptosis or by activating the ROS synthesis. The change in expression of genes upon the administration of droxinostat revealed that this inhibitor causes the inhibition of histone deacetylases. It has shown specific activity against HDAC3, HDAC 8 and HDAC 6. This action of droxinostat is against HDACs which makes the cells sensitive towards the ligand molecules associated FTY720 with death receptors. In a nut shell, one of the novel inhibitors to HDACs, Droxinostat is very valuable FTY720 in making the cancerous cells sensitive to different death inducing signals.
