Novel Spiro-pyrrolizidine-Oxindole and Spiropyrrolidine-Oxindoles: Green synthesis under Classical, Ultrasonic, and microwave conditions and Molecular docking simulation for antitumor and type 2 diabetes

Abstract

Novel spiropyrrolizine / pyrrolidineoxindole moieties were synthesized chemo-, and regio-selectively in high yields from knoevenagel reaction of bis[arylmethylidene]piperidin-4-ones, isatin and L-proline or sarcosine under classical, ultrasonic, and microwave conditions. Seven derivatives of the synthesized dispiro-pyrrolizidine-oxindole and spiropyrrolidine were screened for their antitumor activity against two cell lines MCF-7 (breast cancer) and HEPG2 (liver cancer). The results of biological activity indicated that the tested derivatives showed potent activity against breast cancer cell MCF-7. Molecular docking simulation screening studies of the synthesized products with each of the receptors of (3hb5) for breast cancer and (4k9g) for liver cancer and their interaction with 1H5U of glycogen phosphorylase B, type 2 diabetes drug were examined. The docking study of dispiro-pyrrolizidine-oxindole and spiropyrrolidine showed promising results with several derivatives.
