“…Cytotoxicity was determined using a modified 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) colorimetric assay (23). HJC was dissolved in dimethylsulfoxide (DMSO; Sigma, St. Louis, MO, USA) and the final concentration of DMSO was 0.1% (v/v).…”

Abstract. The aim of this study is to investigate whether HJC, isolated from Justicia procumbens for the first time, can suppress the proliferation and induce apoptosis of human leukemia K562 cells and finally clarify its related mechanism. The chemical structure of HJC was validated by LC-ESI-MS/MS, cytotoxicity was assayed using MTT, and apoptosis was investigated by flow cytometry. These assays indicated that HJC remarkably inhibited the growth in K562 cells by decreasing cell proliferation, reducing the SOD activity, enhancing ROS levels and inducing apoptosis. Activation of caspase-3 indicated that HJC may be inducing intrinsic and extrinsic apoptosis pathways and that HJC-induced apoptosis was caspase-dependent. This study suggests that HJC is a high-potency anti-tumor agent, and it induces apoptosis through a caspase-dependent pathway in human leukemia K562 cells. It also presents a potential alternative to leukemia therapy.

Background Cancer is considered as the second deadliest disease globally. Plants have continuously offered unique secondary metabolites with remarkable biological applications. Lignans have gained great importance due to their biological activity. Previous studies revealed that the most remarkable bioactivity of lignan class of molecules is anticancer. They are derived from the oxidative dimerization of two phenylpropanoid units. This review covers the isolated anticancer lignans and their mechanistic aspects. Main body A bibliographic investigation was performed by analyzing the information available on anticancer lignans in the internationally accepted scientific databases including Web of Science, SciFinder, PubMed, Scopus, and Google Scholar. In this review we have tried to sum up the isolated anticancerous lignan, its source, active plant part, extract and various cell lines used to establish different studies. Here we have included a total number of 113 natural lignans. Many studies that mainly performed in human cell lines have reported. Very few plants have been evaluated for their in vivo anticancer activity. Conclusion It can be concluded that in near future the lignans may be an effective pharmacon for the treatment of cancer. Fruitful areas of future research may be in modifying natural lignans or synthesizing new lignans with structural diversity and potent pharmacological activities. Extensive studies are needed to be done highlighting the mechanism of anticancer action of explored and unexplored plants. The data will definitely attract many researchers to start further experimentation that might lead to the drugs for the cancer treatment. Graphical Abstract
