Biological Activity

LYN-1604 is a novel activator of ULK1, inducing cell death involved in ATF3, RAD21, and caspase3, accompanied by autophagy and apoptosis. LYN-1604 has an IC50 of 1.66 μM against MDA-MB-231 cells, and it binds to wild-type ULK1 with a binding affinity in the nanomole range (Kd=291.4 nM). The ULK1 (Y89A) mutant protein caused a sharp decrease in binding affinity with lower response and Kd than wild-type ULK1, ULK1 (K50A) and ULK1 (L53A) mutants.

Cell Experiment
Cell lines MDA-MB-231 cells
Preparation method Cells are dispensed in 96-well plates at a density of 5 × 104 cells per mL. After 24 h of incubation, cells are treated with different concentrations of compounds for the indicated time periods. Cell viability is measured by the MTT assay.
Concentrations 0.5, 1.0 and 2.0 μM
Incubation time 24 h
Animal Experiment
Animal models MDA-MB-231 xenograft model (BALB/c nude mice)
Formulation -
Dosages 25 mg/kg, 50 mg/kg, 100 mg/kg
Administration intragastric administration
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
