- Visible Light-Promoted Photocatalytic C-5 Carboxylation of 8-Aminoquinoline Amides and Sulfonamides via a Single Electron Transfer Pathway
-
An efficient photocatalytic method was developed for the remote C5-H bond carboxylation of 8-aminoquinoline amide and sulfonamide derivatives. This methodology uses in situ generated ?CBr3 radical as a carboxylation agent with alcohol and is further extended to a variety of arenes and heteroarenes to synthesize the desired carboxylated product in moderate-to-good yields. The reaction proceeding through a single electron transfer pathway was established by a control experiment, and a butylated hydroxytoluene-trapped aryl radical cation intermediate in high-resolution mass spectrometry was identified.

- Synthesis and in vitro evaluation of novel 8-aminoquinoline-pyrazolopyrimidine hybrids as potent antimalarial agents
-
In the search of novel chemotherapeutic agents for emerging drug resistant parasites, the hybridization approaches have successfully emerged as an efficient tool in malarial chemotherapy. Herein, a rational design and synthesis of novel 8-aminoquinoline and pyrazolopyrimidine hybrids and their antimalarial activity against wild type Plasmodium falciparum (Pf-NF54) and resistant strain (Pf-K1) is reported. The medicinal chemistry approach to expand the scope of this series resulted in an identification of potent compounds with nanomolar potency (best IC50 5-10 nM). Systematic structure activity relationship (SAR) studies revealed that pyrazolopyrimidine and 8-aminoquinoline ring are essential for achieving good P. falciparum potency. The docking study revealed that the compound 6 can retain some of the critical interactions within pfDHODH drug target.
