Eriocalyxin B (0-3.5 μM; 7 days) inhibits adipogenesis (IC50: 2.745 μM) and suppresses the expression of key regulators of adipocyte differentiation, including C/EBPα, C/EBPβ, PPARγ, and FABP4 in 3T3-L1 preadipocytes[1].
Eriocalyxin B (1.25-3.5 μM; 16-48 h) induces G2/M phase arrest and inhibits the expression levels of cell cycle regulators in differentiated 3T3-L1 cells[1].
Eriocalyxin B (48 h) is cytotoxic to tumor cells such as A-549, MCF-7, SMMC-7721, SW-480, and HL-60, with IC50 values ranging from 0.3-3.1 μM[2].
Eriocalyxin B (0.35-2.25 μM; 24-72 h) inhibits cell viability, increases intracellular ROS production, and induces apoptosis and autophagy in MCF-7 and MDA-MB-231. The mechanism involves the inhibition of the Akt/mTOR/p70S6K signaling pathway[3].

Cell Line:3T3-L1 cells
-
Concentration:1.25, 2.5, 3 and 3.5 μM
-
Incubation Time:24 h
-
Result:Inhibited the levels of CDK1, CDK2, Cyclin A and Cyclin B1.
Eriocalyxin B (10 mg/kg; intraperitoneal injection; 18-28 days) has an ameliorating effect in a mouse model of experimental autoimmune encephalomyelitis (EAE)[4].

-
Animal Model:Female NOD/SCID mice aged 6-8 weeks old treated MDA-MB-231 cells[3]
-
Dosage:10 mg/kg
-
Administration:Intraperitoneal injection (i.p.); 27 days
-
Result:Led to a slower tumor growth rate and reduced final tumor weight.
Caused no significant change in body weight and liver enzyme levels in plasma (ALT, AST and LDH) after treatment.
Activated autophagy and apoptosis in vivo.
-
Animal Model:Female C57BL/6 mice aged 6-8 weeks old with EAE model[4]
-
Dosage:10 mg/kg
-
Administration:Intraperitoneal injection (i.p.); 11 days after or on the day of immunization for the treatment, continued until 28 days
-
Result:Led to amelioration of EAE, which correlated with reduced spinal cord inflammation and demyelination.
Abolished encephalitogenic T-cell responses to myelin oligodendrocyte glycoprotein in an adoptive transfer EAE model. The underlying mechanism of EriB-induced effects involved inhibition of T helper (Th) 1 and Th17 cell differentiation through Janus Kinase/Signal Transducer and Activator Of Transcription and Nuclear factor-κB signaling pathways as well as elevation of reactive oxygen species.
