Rationalized design, synthesis and pharmacological screening of amino acid linked spiro pyrrolidino oxyindole analogs through environment friendly reaction

Abstract

Introduction:The development of newer synthetic approaches toward the synthesis of polynuclear heteroaromatics and their application in the synthesis of some biologically active compounds has been discussed in this study.Materials and Methods:The synthesis of novel spiro pyrrolidino oxindoles was performed for the construction of amino acid linked polynuclear heteroaromatics by cycloaddition reaction. This reaction method is one of the most important methods for the construction of spiro pyrrolidino oxindole from the commercially available starting material isatin. Then the synthesized compounds were subjected for evaluation of nitric oxide scavenging and cytotoxic effects against tumor cell lines.Results:All the six synthesized compounds demonstrated promising antioxidant and cytotoxic effects in vitro.Conclusion:Form the present study, it can be concluded that the synthesized compounds are fruitful in terms of their chemical purity, structural novelty, marked biological activities (antioxidant and cytotoxic) in vitro and last of all the lucid and picturesque synthetic methodology to synthesize the molecules in a in a non-hazardous and environmental friendly way.

Medicinal plants and natural products can play a significant role in mitigation of mercury toxicity

“…Higher plants, whether dietary or medicinal, and their constituents traditionally possessed an overriding impact in drug discovery and served as the basis of premature medicines (Das et al, 2013; Bhattacharya & Haldar, 2011). There is ample literature currently being available on usefulness of medicinal plants and constituents thereof against experimental mercury and other heavy metal/metalloid poisonings (Bhattacharya, 2017; 2018).…”
