Synthetic ether-linked analogues of phosphatidylcholine and lysophosphatidylcholine, collectively named as antitumour lipids (ATLs), were initially synthesized in the late 60s, but have attracted a renewed interest since the finding that the ether lipid 1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine (ET-18-OCH3, edelfosine), a synthetic analogue of 2-lysophosphatidylcholine considered the ATL prototype, induces a selective apoptotic response in tumour cells, sparing normal cells. Unlike most chemotherapeutic agents currently used, ET-18-OCH3 does not interact with DNA, but act at the cell membrane, and thereby its effects seem to be independent of the proliferative state of target cells. Each part of the molecular structure of ET-18-OCH3 is important for its optimal proapoptotic activity. Recent progress has unveiled the molecular mechanism underlying the apoptotic action of ET-18-OCH3, involving membrane rafts and Fas/CD95 death receptor, and has led to the proposal of a two-step model for the ET-18-OCH3 selective action on cancer cells, namely: a) ET-18-OCH3 uptake into the tumour cell, but not in normal cells; b) intracellular activation of Fas/CD95 through its translocation and capping into membrane rafts. ET-18-OCH3 constitutes the first antitumour drug acting through the intracellular activation of the Fas/CD95 death receptor. Computational docking studies have allowed us to propose a molecular model for the putative interaction of ET-18-OCH3 with the intracellular Fas/CD95 death domain. This novel mechanism of action represents a new way to target tumour cells in cancer chemotherapy and can be of interest as a new framework in designing novel and more selective proapoptotic antitumour drugs[1].

| Additional Infomation |
1-octadecyl-2-methylglycero-3-phosphocholine is a glycerophosphocholine that is glycero-3-phosphocholine substituted at positions 1 and 2 by octadecyl and methyl groups respectively.
Edelfosine is a synthetic analog of lysophosphatidylcholine, an ether lipid, possessing anti-leishmanial and antineoplastic activity. The mechanism of action for edelfosine has not been fully elucidated. Targeting cellular membranes, edelfosine modulates membrane permeability, membrane lipid composition, and phospholipid metabolism. Edelfosine also inhibits the phosphatidylinositol 3 kinase (PI3K)-AKT/PKB survival pathway, possibly activating the pro-apoptotic stress-activated protein kinase (SAPK/JNK) pathways, thereby inducing apoptosis. In addition, this agent inhibits protein kinase C, intracellular activation of the Fas/CD95 receptor, and intracellular acidification. Anti-leishmanial activity may be due to inhibition of a glycosomal alkyl-specific-acylCoA acyltransferase. (NCI) |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
