Abstract
Pyrazoles, and in particular their fluorinated derivatives, are valuable heterocyclic moieties in medicinal chemistry. Our research group recently developed a one-pot, two-step synthesis of pyrazolo[3,4-c]isochromenes, combining two privileged structures into a single hybrid molecule. Based on the preliminary anticancer screening results of these derivatives, herein, we designed a next-generation compound library focused on the derivatization of a specific portion of the 1-(trifluoromethyl)-3,5-dihydroisochromeno[3,4-c]pyrazole scaffold via late-stage functionalization. The diverse reactivity of aryldiazonium tetrafluoroborate salts was leveraged to achieve this and generate a small but varied compound library. The new series was tested for their anticancer properties and selected derivatives demonstrated pro-apoptotic activity in the human cervical carcinoma cell lines HeLa. The obtained results highlight these structures as valid candidates for further biological studies, while the streamlined synthetic route offers a facile approach to further structural analogs.
期刊介绍:
Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC)
The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
