Name: 4-Chloro-4′-ethynyl-1,1′-biphenyl. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Chloro-4′-ethynyl-1,1′-biphenyl, is researched, Molecular C14H9Cl, CAS is 57399-11-8, about Synthesis and Antiplasmodial Activity of New Indolone N-Oxide Derivatives.

A series of 66 new indolone-N-oxide derivatives, e.g. I, was synthesized with three different methods. Compounds were evaluated for in vitro activity against CQ-sensitive (3D7), CQ-resistant (FcB1), and CQ and pyrimethamine cross-resistant (K1) strains of Plasmodium falciparum (P.f.), as well as for cytotoxic concentration (CC50) on MCF7 and KB human tumor cell lines. Compound II (5-methoxy-indolone-N-oxide analog) had the most potent antiplasmodial activity in vitro (<3 nM on FcB1 and = 1.7 nM on 3D7) with a very satisfactory selectivity index (CC50 MCF7/IC50 FcB1: 14623; CC50 KB/IC50 3D7: 198823). In in vivo experiments, compound I (dioxymethylene derivatives of the indolone-N-oxide) showed the best antiplasmodial activity against Plasmodium berghei, 62% inhibition of the parasitemia at 30 mg/kg/day. After consulting a lot of data, we found that this compound(57399-11-8)Name: 4-Chloro-4′-ethynyl-1,1′-biphenyl can be used in many types of reactions. And in most cases, this compound has more advantages.
