Design, Synthesis, and Evaluation of Anticancer Activity of Some New Spiro Indoline-2-one Derivatives

The indoline-2-one derivatives (SSSK 16-20) were designed by docking, in silico absorption, distribution, metabolism, and excretion (ADME) and predicted toxicity studies. These designed compounds were then synthesized by a three-component coupling reaction. These compounds were characterized by ‘H nuclear magnetic resonance (H-1 NMR), C-13 NMR, Fourier transform infrared, and mass spectral data. Then, all synthesized compounds were tested for anticancer activity on MDA-MB-231 and MCF-7 cell lines. The compounds having halogen at isatin ring displayed good binding scores. In silico, ADME and toxicity studies were also found significant for most of the compounds. Three compounds SSSK16, SSSK17, and SSSK19 showed significant anticancer potential against MCF-7 with GI(50) value of 0.44, 0.04, and 21.6 molar.

Computational Design of Enhanced Enantioselectivity in Chiral Phosphoric Acid-Catalyzed Oxidative Desymmetrization of 1,3-Diol Acetals

A general method for the highly enantioselective desymmetrization of 2-alkyl-substituted 1,3-diols is presented. A combination of computational and experimental studies has been utilized to understand the origin of the stereocontrol of oxidative desymmetrization of 1,3-diol benzylideneacetals. DFT calculations demonstrate that the acetal protecting group is highly influential for high enantioselectivity, and a simple but effective new protecting group has been designed. The desymmetrization reactions proceed with high enantioselectivity for a variety of substrates. Moreover, the reaction conditions are also shown to be effective for desymmetrization of 2,2-dialkyl-substituted 1,3-diols, which provides chiral products bearing acyclic all-carbon quaternary stereocenters. The method has been applied to the formal synthesis of indoline alkaloids.

Transition-metal-free polycyclic indoline formation via a free radical pathway: a computational mechanistic study

The mechanism of [2 + 2 + 1] cyclization reactions to access polycyclic sulfonyl indolines via Fe(II)-catalyzed or UV-driven has been investigated by density functional theory (DFT) methods. Mechanistic studies aided by the DFT calculations suggest that the reaction might proceed via a free radical pathway with HSO3 center dot serving as the initiator and terminator of the free radical reaction, which has never been reported to our knowledge. The reactions involve the formation of two five-membered rings. The calculated results show that the first five-membered ring formation is the rate-determining step, with an energy barrier of 3.2 kcal/mol. And the second five-membered ring formation is an exergonic process. It is worth noting that HSO3 center dot radicals are involved in the reaction preceding the formation of the second ring, and they facilitate formation of the second ring. Meanwhile, the most active site was predicted by the condensed Fukui function (CFF) and verified by DFT calculations.
