The ability of these novel spermicides to kill sperm almost instantaneously at innocuously low concentration indicates their worth as improved active ingredients for vaginal contraceptive preparations compared with N-9.

Preliminary studies have revealed that in sharp contrast to the non-specific surfactant action of N-9, DSE-36 and DSE-37 have a highly potent, mechanism-based, detrimental action on human sperm. The unique ability of these non-detergent molecules to selectively kill sperm and spare Lactobacilli and HeLa cells at MEC values much lower than that required for N-9 indicates their potential as superior ingredients for formulation into microbicidal contraceptives.

Sulfur‐containing indoles are widely studied against different biological targets. Among several potential drug candidates, seven molecules of this class are in the current market and a few of them are either in pipeline or in different stages of clinical trials. Particularly, arylthioindoles or indolylarylsulfones (IAS) received great attention by medicinal chemists due to their pharmokinetic profiles and wide spectrum of biological activities like antiviral, anticancer, cardiovascular, and antibacterial properties. This review summarizes the developmental process, synthesis and structure activity relationship (SAR) around arylthioindole/indolylaryl sulfone scaffolds for antiviral/anti‐HIV non‐nucleoside reverse transcriptase inhibitor (NNRTIs) activities. It also offers perspective for further development of 3‐indolylarylsulfones as an anti‐viral agent including their potential against novel COVID‐19 infection.
