Biological Activity

TD52, an erlotinib analog, is a putative inhibitor of CIP2A that exhibits potent antitumor efficacy on HCC and TNBC cells. TD52 induces apoptosis through downregulation of CIP2A (Cancerous inhibitor of protein phosphatase 2A) in HCC, NSCLC and TNBC cells. Apparently TD52 indirectly downregulates CIP2A transcripts through interrupting the binding of Elk1 to CIP2A promoter. TD52 is a weak inhibitor of EGFR tyrosine kinase.

Conversion of different model animals based on BSA (PMID: 27057123)
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.

Poly(ethylene glycol) diacrylate

Poly(ethylene glycol) diacrylate (PEGDA) is a blank slate hydrogel that gels rapidly at room temperature in the presence of a photoinitiator and light. PEGDA hydrogels are potent tools for uncovering basic cellular biology. PEGDA is an emerging scaffold for tissue engineering and regenerative medicine since polymerization can occur rapidly at room temperature, requires low energy input, has high water content, is elastic, and can be customized to include a variety of biological molecules.
