This disclosure relates to novel compounds containing an H
2
S releasing moiety and a nitric oxide (NO) releasing moiety covalently linked with a core (e.g., a salicylic acid moiety) and the use of such compounds in treating inflammatory diseases, including cancers. Therapeutic potency of these compounds is significantly higher than NSAIDs containing a H
2
S-releasing moiety alone (HS-NSAIDs) and NSAID containing a NO-releasing moiety alone (NO-NSAIDs). The compounds, in addition, exhibit reduced side effect, e.g., reduced stomach ulcers, upon administration.

Methyl, ethyl, and isopropyl esters of six alkanesulfonic acids and five p-substituted benzenesulfonic acids were synthesized and their alkylating abilities were evaluated in terms of the chemoselectivity toward 4-(p-nitrobenzyl) pyridine (NBP) in phosphate buffer (pH 6.0) containing 60% acetone. The chemoselectivity constant toward NBP, SNBP, was defined as the logarithm of the ratio of the molar fraction of an alkylating sulfonate which is consumed for alkylation of NBP versus the molar fraction of the residual alkylating agent which is hydrolyzed in the buffer medium. It was found that SNBP was not only markedly dependent on the structure of the alkyl moiety of the molecule, but also appreciably dependent on the electronic nature of the leaving sulfonic acid moiety. The structure-chemoselectivity relationship is discussed.
