Regulatory activities of the cell that are related to its multiplication, movement, transcription and as well as translation of the genes is controlled by mTOR pathway which is one of the important various cell cycle regulators. FRAP1 gene is translated to produce mTOR which phosphorylates serine/threonine residue of proteins. Cancer usually arises from the down-regulation of this mTOR cascade. So for targeted cancer therapy proteins like it are also taken under consideration [1].Different types of inhibitors are being searched and Everolimus mTOR inhibitor is one of the very promising inhibitors [2]. Novartis which is pharmaceutical company produced it and sell it with as Afinitor Everolimus which is its trade name. Since structural studies revealed that Everolimus is a derivative of 40-O-(2-hydroxyethyl), the pharmacokinetic properties are seemed to be improved due to the availability of oxygen atom the 40 position. Against mTOR Everolimus IC50 is approximately 1nM.Around 100mg/ml of DMSO is suitable for Everolimus solubility. It is water and ethanol soluble. The mode of administration of Everolimus is through oral route and it is present in 5mg of packaging and approximately $60 is Everolimus price. Dry-ice is used for its distribution.

Everolimus acts as immunosuppressant in different types of transplantations like heart and kidney transplant. Among other properties of Everolimus it is administered as anti-cancer drug and proved efficient enough [4] by controlling the mTOR1 which ultimately leads to the activation of Akt pathway and causes the inhibition of mTOR2 pathway. When administered alone Everolimus has been shown to cause the programmed cell death of colon cancerous cell [5] or even when it is co-administered with different drugs e.g. Octreotide it revealed to inhibit Akt-mTOR-p70S6 pathway in tumor cells of neuroendocrine [6]. To treat kidney tumors Everolimus is successfully used [7]. The promising results of pharmacokinetics of Everolimus have compelled scientists to evaluate its efficacy in detail [8].

For the treatment of coronary artery disease and ischemia Everolimus can be employed as stents. The conventional stents like Paclitaxel were compared with Everolimus in context of efficiency [9-10]. It has also been tried to make Everolimus a bio-absorbable stent so that it can be used for the treatment of CAD (coronary artery disease) [11].

Among the mTOR inhibitors that are available Everolimus is the most efficient and best. Its effect on cancer cell lines of breast was evaluated [12] which favored to study in detail the effects of drug [13]. It has been evaluated in phase II clinical trials when administered alone [15] and its study is in phase I when it is co-administered in relapsed breast cancer [15]. It is also studied in patients who are reported to be hormone receptor positive [16].
The in vivo studies of the medicine against gastric cancer have been reported in combination with other therapies [17].  The results suggested that it can also be employed in the later periods of stomach cancer [18] which continued it to enter the phase II trials [19]. After the kidney is transplanted the effect of Everolimus as immunosuppressant has been reported [20].A comparative study was done to evaluate the efficiency of drug in kidney cancer it showed promising results than Azathioprine [21] which is also used as immunosuppressant in renal transplants.
Everolimus can also be for treatment of carcinoids where good results were shown by mTOR inhibitor [22]. It is co-administered with Octreotide and efficiency was evaluated in phase II clinical trials [23]. Everolimus has proved to be effective therapeutic agent against carcinoids [24] so a lot of research work is being done to develop more effective drug. The drug is also efficient for carcinoids treatment where mTOR inhibitor gave good results [22]. In combinatorial therapy, done in clinical trial phase II the drug was also used with Octreotide against neuroendocrine cancer [23]. Everolimus is considered a unique therapeutic agent that is effective against carcinoids [24] therefore further research is being made on the drug in order to produce more value able drug.
