α-Lipoicacidderivatives were synthesized and evaluated for their in vitro anticancer activities against NCI-460, HO-8910, KB, BEL-7402, and PC-3 cell lines. The results, for most compounds exhibited dose-dependent inhibitory property and several compounds had good inhibitions at the dose of 100 μg/mL. Compound 17m was further selected for in vivo evaluation against S180 xenograft in ICR mice, which
