Synthesis, computational study, and evaluation of in vitro antimicrobial, antibiofilm, and anticancer activities of new sulfanyl aminonaphthoquinone derivatives

Abstract

Background: A set of novel sulfanyl aminonaphthoquinone derivatives (5a-j) were synthesized starting from 2,3-dichloro-1,4-naphthoquinone (1). The amine substituents were introduced via a nucleophilic substitution at reflux temperature. Subsequent reactions of 2-chloro-3-arylamino-1,4-naphthoquinones (3a-d) with different thiols (4a-c) led to the formation of the desired amino-and thio-substituted products (5a-j).
