Cell experiment: | For harringtonine treatment studies with Sindbis virus, BHK21 cells are seeded into 96-well plates and infected with Sindbis virus at an MOI of 1 for 1 h prior to being washed twice with PBS and incubated with various concentrations of harringtonine (0.1 μM, 1 μM, 5 μM, and 10 μM) at 37°C with 5% CO2. Cell supernatants are harvested for plaque assays at 24 h postinfection[2]. |

Harringtonine is a protein synthesis inhibitor [1].
Harringtonine, homoharringtonine and isoharringtonine are alkaloids from Cephalotaxus harringtonia. They have an antitumour activity due to their inhibitory effect on protein synthesis and differ only in a side chain [1].
Harringtonine is a natural alkaloid from Cephalotaxus harringtonia that inhibits protein synthesis in eukaryotic cells. Harringtonine inhibit the initiation of polypeptide synthesis. Harringtonine blocks peptide bond formation and aminoacyl-tRNA binding [1][2]. Harringtonine also immobilizes ribosomes immediately after translation initiation, which can be used to capture ribosome-protected mRNA fragments for evaluating translation [2]. The homolog of harringtonine, homoharrington inhibited the first steps of elongation and rapidly degraded short-lived proteins. In Pten+/- Eμ-Myc lymphomas, homoharrington blocked translation and reduced levels of Mcl-1, Cyclin D1, and c-Myc.
In mice with BCR-ABL-induced CML, homoharrington (also known as omacetaxine) significantly reduced the numbers of both LSCs and total leukemia cells [3][4].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
