Coumarin-Dithiocarbamate Derivatives as Biological Agents.

Coumarin derivatives, whether natural or synthetic, have attracted considerable interest from medicinal chemists due to their versatile biological properties. Their appealing pharmacological activities-such as anticancer, anti-inflammatory, neuroprotective, anticoagulant, and antioxidant effects-combined with the ease of their synthesis and the ability to introduce chemical modifications at multiple positions have made them a widely explored class of compounds. In the scientific literature, there are many examples. On the other hand, dithiocarbamates, originally employed as pesticides and fungicides in agriculture, have recently emerged as potential therapeutic agents for the treatment of serious diseases such as cancer and microbial infections. Moreover, dithiocarbamates bearing diverse organic functionalities have demonstrated significant antifungal properties against resistant phytopathogenic fungi, presenting a promising approach to combat the growing global issue of fungal resistance. Dithiocarbamates linked to coumarin derivatives have been shown to exhibit cytotoxic activity against various human cancer cell lines, including MGC-803 (gastric), MCF-7 (breast), PC-3 (prostate), EC-109 (esophageal), H460 (non-small cell lung), HCCLM-7 (hepatocellular carcinoma), HeLa (cervical carcinoma), MDA-MB-435S (mammary adenocarcinoma), SW480 (colon carcinoma), and Hep-2 (laryngeal carcinoma). Numerous studies have revealed that the inclusion of a dithiocarbamate moiety can provide central nervous system (CNS) activity, particularly through inhibitory potency and selectivity toward acetylcholinesterase (AChE) and monoamine oxidases (MAO-A and MAO-B). Recently, it has been reported that coumarin-dithiocarbamate derivatives exhibit α-glucosidase inhibitory effects and also possess promising antimicrobial activity. This study presents an overview of recent progress in the chemistry of coumarin-dithiocarbamate derivatives, with a focus on their biological activity. Previous review papers focused on coumarin derivatives as multitarget compounds for neurodegenerative diseases and described various types of compounds, with dithiocarbamate derivatives representing only a small part of them. Our work deals exclusively with coumarin dithiocarbamates and their biological activity.
