The sweeteners saccharin (
SAC
) and acesulfame K (
ACE
) recently entered the topic of anticancer human carbonic anhydrase (CA, EC 4.2.1.1) inhibitors, as they showed to selectively inhibit the tumor-associated CAs IX/XII over ubiquitous CAs. A drug design strategy is here reported, which took
SAC
and
ACE
as leads and produced a series of 2

)-one-1,1-dioxides (
BTD
). Many derivatives showed greater potency (

s-CA IX 103, 2400 nM; II/IX-SI 56, >4) against CA IX/XII over off-target isoforms. A thorough X-ray crystallographic study depicted their binding mode to both CA II and IX-mimic. The most representative
BTDs
were characterized in vitro for their antitumor activity against A549, PC-3, and HCT-116 cancer cell lines both in normoxia and hypoxia. The two most effective compounds were assayed for their effect on several apoptosis markers, identifying promising leads for the development of new anticancer drugs.
