R5 R4 OH HO 0 1 SI(I) OHO wherein, R, represents - H, - OH, a linear or branched alkyl group with I to 3 carbon atoms, or an isoprene group R2, R3, R4, R5, R6 and R7 represent - H, - OH, a linear or branched alkyl group with I to 3 carbon atoms, an isoprene group or a geranyl group represented by formula (II) or (III), respectively. H3 H3 CH3 Ha-I (II) CH3 (HI) The compound of the present invention can increase the survival rate of neural cells even at a low cellular density in a culture medium. The compound of the present invention can also promote the growth of neurons, which is revealed by the increase in the thickness, length and number of branches in the neurites (neural fibers). In addition, the compound of the present invention can be used to promote the development of neural stem cells and induce them to differentiate into neurons.
