New potent inhibitors of tyrosinase: Novel clues to binding of 1,3,4-thiadiazole-2(3H)-thiones, 1,3,4-oxadiazole-2(3H)-thiones, 4-amino-1,2,4-triazole-5(4H)-thiones, and substituted hydrazides to the dicopper active site

hydrazides were tailored and synthesized as new potent inhibitors of tyrosinase. The rationale for inhibitor design was based on the active site structural evidence from the crystal structures of bacterial tyrosinase and potato catechol oxidase enzymes. Kinetic and active site binding studies suggested mono-dentate binding of thiadiazole, oxadiazole, and triazole rings to the active site dicopper center
The present invention is directed to oxadiazole linkers and use thereof, more specifically to the compounds represented by formula I, II, and III, and their use in the preparation of antibody-drug conjugates (ADCs). The ADCs obtained from said oxadiazole linkers have high homogeneity and stability, and could be used effectively for the treatment of various diseases including tumors. The definition of the groups in formula I, II, and III is the same as that in the description.
