Benzothiazole–Triazole–Indazole Conjugates: Design, Characterization, and Preliminary In Vitro MTT-Based Antiproliferative Evaluation
A new library of benzothiazole–triazole–indazole conjugates (5a–s) was efficiently synthesized via a Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) strategy. The approach involved the preparation of alkynylated indazoles and benzothiazole–azide derivatives, followed by click-chemistry cycloaddition to provide triaz...
