Stereoselective synthesis of β-arabino glycosyl sulfones as potential inhibitors of mycobacterial cell wall biosynthesis

A series of β-arabino glycosyl sulfones with varying alkyl chain lengths were synthesised in a stereoselective fashion as putative mimics of decaprenolphosphoarabinose (DPA), and as potential inhibitors of mycobacterial cell wall biosynthesis. Biological testing against Mycobacterium bovis BCG revealed low to moderate anti-mycobacterial activity with marked dependence on alkyl chain length, which was maximal for a C-12 chain.
