This paper reports a study on the photolysis of an aryl pentazole in solution. 4-Oxidophenylpentazole (OPP) was irradiated in water and in acetonitrile at its first absorption band (320 and 370 nm, respectively) and at 193 nm. 4-Oxidophenylazide (OPA) was also investigated under similar conditions for comparison. NMR and UV–vis absorption spectroscopies of the products show that the major stable products

Cysteine esters and amides spontaneously degrade under physiological conditions to generate H2S. This discovery not only provides new insights into fundamental science issues, but also inspires a class of tunable cleavage motifs for prodrug design.
