Biological Activity

Description COTI-2 is an orally available third generation thiosemicarbazone and activator of mutant forms of the p53 protein, with potential antineoplastic activity.
Targets
p53 mutants [1]
In vitro
In vitro The thiosemicarbazone COTI-2 is reported to promote refolding of mutant p53 and restore wild-type-p53 function. It is active against human tumour cell lines of various origins at nanomolar concentrations, induces cell death by apoptosis[1]. COTI-2 is highly efficacious against multiple cancer cell lines from a broad range of human cancers both in vitro and in vivo. COTI-2 does not significantly inhibit over 200 kinases from major kinase pathways involved in cancer that were evaluated in both kinase assays and does not inhibit the ATPase activity of Hsp90, a ubiquitous molecular chaperone that plays an essential role in cell survival and cell cycle control[2].
Cell Research Cell lines SHP-77 cells
Concentrations 100, 250, 1000 nM
Incubation Time 48 h
Method

SHP-77 cells were cultured with various concentrations of COTI-2 for 48 h. Cells were then washed twice with 1X cold PBS and stained with Annexin V and 7AAD. Briefly, 5 μl of Annexin V and 7AAD were added to 1 × 105 cells and incubated for 15 min at room temperature in the dark. Then 400 μl of the 1X binding buffer was added to the cells.
In Vivo
In vivo COTI-2 significantly inhibited tumor growth in the HT-29 human colorectal tumor xenografts at a dose of 10 mg/kg. COTI-2 also significantly inhibited tumor growth in the SHP-77 SCLC xenograft model at a dose as low as 3 mg/kg. Its treatment delays U87-MG, MDA-MB-231 and OVCAR-3 xenograft growth. COTI-2 treatment demonstrates a safe toxicity profile in vivo. COTI-2 selectively targets a wide variety of human cancer cell lines, as demonstrated by the in vitro data, while having little deleterious effects on normal cells[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
