The synthesis and utility of three benzoxaborole protecting groups are reported. These protecting groups improve organic solubility and allow otherwise incompatible reactions (oxidations, substitutions, and mild reductions) to be achieved in the presence of the benzoxaborole moiety. 3-(N,N-Dimethylamino)-1-propanol was determined to be useful in one-step sequences and is readily cleaved upon workup. Two other groups, N-methylsalicylidenimine and 2-[1-(methylimino)ethyl]phenol, are suitable for multistep syntheses. Deprotection with mild aqueous acid allows for chromatography-free isolation of the benzoxaborole in high yields.

Arylphosphonium-benzoxaborole conjugates have been synthesized as potential mitochondria targeting anticancer agents. The synthesized compounds have been tested for their effects on cell viability in various solid tumor cell lines including breast cancer 4T1 and MCF-7, pancreatic cancer MIAPaCa-2 and colorectal adenocarcinoma WiDr. Compound 6c is designated as a lead compound for further studies due to its enhanced effects on cell viability in the above-mentioned cell lines. Seahorse Xfe96 based metabolic assays reveal that the lead candidate 6c inhibits mitochondrial respiration in 4T1 and WiDr cell lines as evidenced by the reduction of mitochondrial ATP production and increase in proton leak. Epiflourescent microscopy experiments also illustrate that 6c causes significant mitochondrial fragmentation in 4T1 and WiDr cells, morphologically consistent with programmed cell death. Our current studies illustrate that arylphosphonium-benzoxaborole conjugates have potential to be further developed as anticancer agents.
