bioactive compounds. However, the atropisomerism arising from a restricted rotation around an N–N bond is largely overlooked. Here, we describe a method to access the first enantioselective synthesis of N–N biaryl atropisomers via a Cu-bisoxazoline-catalyzed Friedel–Crafts alkylation reaction. A wide range of axially chiral N–N bisazaheterocycle compounds were efficiently prepared in high yields with
better protections than the reference. The most prospective compounds comprised salicylicacid moieties, whose 4‐substituted derivatives were related to lower acute toxicity and considerable activity. 4‐[3‐(Ethoxycarbonyl)‐2‐methyl‐5‐(3,4‐dimethoxy‐phenyl)‐1H‐pyrrol‐1‐yl]‐2‐hydroxy‐benzoic acid 3c was pointed out as the most prospective substance due to its lower acute toxicity (378 mg/kg body weight,

MCF-7 (IC50 1.883 µM) but slightly lower activity against MDA-MB-231 cells (IC50 4.688 µM). The activity of both the compound was also tested on 3T3L-1 Cell line which showed activity similar to clinically approved anti-cancer drug doxorubicin (DOX). The cell death analysis by flow-cytometry confirmed apoptosis mediated cell death in 3T3L-1, MCF-7 and MDA-MB-231 cells when treated with the NAM-5 and NAM-7
To develop new classes of antimalarialagents, the possibility of replacing the phenolic ring of amodiaquine, tebuquine, and isoquine with other aromatic nuclei was investigated. Within a first set of pyrrole analogues, several compounds displayed high activity against both D10 (CQ-S) and W-2 (CQ-R) strains of Plasmodium falciparum. The isoquine structure was also modified by replacing the diethylamino
