In our previous study we developed a novel series of tetrahydroisoquinoline - based hydroxamic acid derivatives as histone deacetylase ( HDAC ) inhibitors ( Bioorg . Med . Chem . , 2010 , 18 , 1761 - 1772 . , J . Med . Chem . , 2011 , 54 , 2823 - 2838 . ) , among which compound ZYJ - 34c ( 1 ) was identified and validated as the most potent one with marked in vitro and in vivo antitumor potency ( J . Med . Chem . , 2011 , 54 , 5532 - 5539 . ) .
