SLV-2436 (SEL201-88)

Cell experiment:

One thousand HBL, MM61, MM111, and M230 cell lines per well are seeded in 6-well plates, and the cells are allowed to adhere overnight. After overnight incubation, the cells are treated with either DMSO (control) or SLV-2436 (5 μM). After 14 days, media are removed from the wells, and the cells are stained with 0.5% (wt/vol) crystal violet in 70% ethanol. After 1 hour of incubation at room temperature, staining dye is washed, and the colony numbers are counted by GelCount. The experiment is done in triplicate[1].

Animal experiment:

Mice[1]The pharmacokinetic profile of SLV-2436 is assessed in 6-week-old female CD-1 mice. SLV-2436 is freshly dissolved in DMSO and then diluted in Captisol for administration with a volume of 10 μL per 1 g of body weight via the oral (p.o.; 5 mg/kg) or i.v. (2 mg/kg) route. Animals are sacrificed at 8 time points (5, 15, and 30 minutes and 1, 2, 4, 6, and 24 hours) and blood samples harvested. Plasma samples are collected and stored at -80°C for further analysis. To evaluate the pharmacodynamic properties of SLV-2436, 10- to 16-week-old male C57BL/6 mice are divided into a control group and 3 dosing groups. Animals are given either vehicle (DMSO+N,N-Dimethylacetamide+Captisol) or SLV-2436 at 10-, 25-, and 50-mg/kg doses (freshly dissolved). Drugs are administered p.o. in a volume of 10 μL per 1 g of body weight. Each animal receive a total of 5 doses with twice-daily schedule (i.e., every 12 hours). Body weight is assessed once daily. Six animals per experimental group supported sample collection at 2 time points (i.e., 4 hours and 24 hours) after the last, fifth administration, with 3 animals per time point. Plasma samples are collected and stored at -80°C for further analysis[1].
