target for cancer drug development. There is a high homology between the human and the parasite enzyme isoforms, in addition to being a druggable target. Looking to repurpose its structure as an antimalarial drug, a collection of S-substituted derivatives of thiosalicylic acid were prepared by introducing 1,2,3-triazole as a diversity entry point or by direct alkylation of the thiol. We further investigated

the most potent activity. Furthermore, three compounds display superior antiproliferative activity than salirasib and similar potency compared to control anticancer drugs across all tested solid tumor cell lines. In addition, the behavior of the collection on migration and invasion, a key process in tumor metastasis, was also studied. Three analogues with specific antimigratory activity were identified

of PTP1B. Findings obtained using this model system suggest that the oxidative transformation of PTP1B to its "crosslinked" inactive form can proceed directly via oxidation of the active-site cysteine to a sulfenicacid (RSOH). The remarkably facile nature of this protein cross-link-forming reaction, along with the widespread cellular occurrence of protein sulfenicacids generated via oxidation of cysteine
