S 1 Result

Screening of Benzofuran Pyran Compounds on palmitate induced lipotoxic in vitro

model

Compound 4j, neither increases the cell viability nor osteoblast differentiation (Fig.S1A and

B). Compound 4k enhanced cell viability at 500pm and 1.0µM (Fig.S1C) but failed to

enhance osteoblast differentiation in presence of palmitate (Fig.S1D).

Figure legend

Fig S1 Compound 4j did not rescue osteoblasts from lipotoxic of palmitate (A) and nor

increase ALP activity in the presence of palmitate (B). Compound 4k significantly increased

cell viability at 500pm and 1µM concentration (C) but failed in increasing ALP activity (D).

Data were presented as the mean ± SE, # p˂0.05, ## p˂ 0.005, ### p˂0.0005 versus control

group and *p˂0.05, **p˂0.005, ***p˂0.0005 versus palmitate group.
