Chemical structure

Aprepitant

Protocol

Cell experiment [1]:

Cell lines

Nalm-6 cells

Preparation method

The solubility of this compound in DMSO is >26.7mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

20 μM

Applications

Aprepitant decreased the metabolic activity with an estimated IC50 value of 20 μM. Aprepitant induced cell-growth inhibition and G1 cell-cycle arrest. Aprepitant significantly induced apoptosis in Nalm-6 cells. Aprepitant (20 μM) induced p53 accumulation and expression of pro-apoptotic p53 target genes.

Animal experiment [2]:

Animal models

Male C57BL/6J mice

Dosage form

Intraperitoneal injection, 10 mg/kg

Application

Aprepitant (10 mg/kg, i.p.) significantly attenuated AMPH-induced CPP expression and locomotor activation produced by AMPH and cocaine in mice. Aprepitant significantly enhanced the expression of CPP produced by morphine while significantly suppressing the locomotor activity of the mice conditioned with morphine.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Aprepitant (also known as MK-0869) is a novel and highly selective Neurokinin-1 (NK-1) receptor antagonist that inhibits the activity of substance P (SP), an undecapeptide belonging to the tachykinin family of peptides, on the NK-1 receptor with the dissociation constant Kd of 86 pM for human NK-1 receptor and the half maximal inhibition concentration IC50 of 0.1 nM, 4 nM and 0.7 nM for human, rat and ferret NK-1 receptors respectively [1,2].

Since SP has been demonstrated to induce cell proliferation in several human cancer cell lines with overexpressed NK-1 receptors, aprepitant has also been found to concentration-dependently induce growth inhibition in a variety of tumor cell lines, including glioma (GAMG), neuroblastoma (SKN-BE2, IMR-32 and KELLY), retinoblastoma (Y-79 and WERI-Rb-1), pancreas carcinoma (PA-TU-8902 and CAPAN-1), larynx carcinoma (HEp-2), gastric carcinoma (23132-87) and colon carcinoma (SW-403), with IC50 of 33.1 μΜ, 24.6 μΜ, 19.6 μΜ, 27.7 μΜ, 30.4 μΜ, 23 μΜ, 31.2 μΜ, 27.4 μΜ, 22.7 μΜ, 24.2 μΜ and 30.5 μΜ respectively [2].
