A series of sulfonamide derivatives were synthesized, and the enzyme inhibitory activity of the synthesized compounds on carbonic anhydrase II was evaluated. Through molecular docking studies, it was found that compounds 1b, 1e, 2a, 2b, 3a have a strong binding affinity to carbonic anhydrase II. The IC50 values of the four compounds 1e, 2b, 3a, and 3b were lower than that of the positive control drug acetazolamide. What’s more, the compounds had a high inhibitory activity for A549 lung cancer cell growth, among them, 1e and 3a could inhibit both carbonic anhydrase II and lung cancer cell proliferation.

Abstract: New sulfanilamide derivatives containing sterically hindered phenol fragments have been synthesized via modification of the amino group by reaction with 3,5-di-tert-butyl-4-hydroxybenzyl acetate and diazotization followed by diazo coupling with
NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).
