Singh M, Sharma P, Singh PK, Singh TG, Saini B. Medicinal Potential of Heterocyclic Compounds from Diverse Natural Sources for the Management of Cancer. Mini Rev Med Chem 2021; 20:942-957. [PMID: 32048967 DOI: 10.2174/1389557520666200212104742] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 11/15/2019] [Accepted: 11/26/2019] [Indexed: 11/22/2022]
Abstract
Natural products form a significant portion of medicinal agents that are currently used for the management of cancer. All these natural products have unique structures along with diverse action mechanisms with the capacity to interact with different therapeutic targets of several complex disorders. Although plants contribute as a major source of natural products with anti-cancer potential, the marine environment and microbes have also bestowed some substantial chemotherapeutic agents. A few examples of anti-cancer agents of natural origin include vincristine, vinblastine, paclitaxel, camptothecin and topotecan obtained from plants, bryostatins, sarcodictyin and cytarabine from marine organisms and bleomycin and doxorubicin from micro-organisms (dactinomycin, bleomycin and doxorubicin). The incredible diversity in the chemical structures and biological properties of compounds obtained from million species of plants, marine organisms and microorganisms present in nature has commenced a new era of potential therapeutic anti-cancer agents.

Abstract
Chiral phosphoric acid-catalyzed biomimetic asymmetric [4 + 2] cycloaddition of ortho-alkenyl naphthols/phenols and ortho-quinone methides (o-QMs) has been demonstrated to afford various important 2,3,4-trisubstituted chromans in high yields with excellent enantio- and diastereoselectivities (up to 99% yield, 99% ee, >20:1 dr). Notably, this methodology not only enabled access to the trans-cis chiral trisubstituted chromans from 1-alkenyl 2-naphthols but also is compatible with 2-alkenyl 1-naphthols and phenols to deliver trans-trans chiral trisubstituted chromans.

Cytotoxicity of the methanol extracts of Elephantopus mollis, Kalanchoe crenata and 4 other Cameroonian medicinal plants towards human carcinoma cells. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 17:280. [PMID: 28545532 PMCID: PMC5445369 DOI: 10.1186/s12906-017-1793-1] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Accepted: 05/15/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Cancer still constitutes one of the major health concerns globally, causing serious threats on patients, their families, and the healthcare system. METHODS In this study, the cytotoxicity of the methanol extract of Elephantopus mollis whole plant (EMW), Enantia chlorantha bark (ECB), Kalanchoe crenata leaves (KCL), Lophira alata bark (LAB), Millettia macrophylla leaves (MML) and Phragmanthera capitata leaves (PCL) towards five human solid cancer cell lines and normal CRL2120 fibroblasts, was evaluated. Extracts were subjected to qualitative chemical screening of their secondary metabolite contents using standard methods. The cytotoxicity of samples was evaluated using neutral red uptake (NR) assay meanwhile caspase activation was detected by caspase-Glo assay. Flow cytometry was used to analyze the cell cycle distribution and the mitochondrial membrane potential (MMP) whilst spectrophotometry was used to measure the levels of reactive oxygen species (ROS). RESULTS Phytochemical analysis revealed the presence of polyphenols, triterpenes and sterols in all extracts. The IC50 values of the best samples ranged from 3.29 μg/mL (towards DLD-1 colorectal adenocarcinoma cells) to 24.38 μg/mL (against small lung cancer A549 cells) for EMW, from 2.33 μg/mL (mesothelioma SPC212 cells) to 28.96 μg/mL (HepG2 hepatocarcinoma) for KCL, and from 0.04 μg/mL (towards SPC212 cells) to 0.55 μg/mL (towards A549 cells) for doxorubicin. EMW induced apoptosis in MCF-7 cells mediated by MMP loss and increased ROS production whilst KCL induced apoptosis via ROS production. CONCLUSION This study provides evidences of the cytotoxicity of the tested plant extract and highlights the good activity of Elephantopus mollis and Kalanchoe crenata. They deserve more exploration to develop novel cytotoxic drugs.

Abstract
Chalcone or (E)-1,3-diphenyl-2-propene-1-one scaffold remained a fascination among researchers in the 21st century due to its simple chemistry, ease of synthesis and a wide variety of promising biological activities. Several natural and (semi) synthetic chalcones have shown anti-cancer activity due to their inhibitory potential against various targets namely ABCG2/P-gp/BCRP, 5α-reductase, aromatase, 17-β-hydroxysteroid dehydrogenase, HDAC/Situin-1, proteasome, VEGF, VEGFR-2 kinase, MMP-2/9, JAK/STAT signaling pathways, CDC25B, tubulin, cathepsin-K, topoisomerase-II, Wnt, NF-κB, B-Raf and mTOR etc. In this review, a comprehensive study on molecular targets/pathways involved in carcinogenesis, mechanism of actions (MOAs), structure activity relationships (SARs) and patents granted have been highlighted. With the knowledge of molecular targets, structural insights and SARs, this review may be helpful for (medicinal) chemists to design more potent, safe, selective and cost effective anti-cancer chalcones.

Abstract
The cytotoxic, antimutagenic, and antioxidant activities of methanolic extract and lophirones B and C derived from Lophira alata stem bark were evaluated. The extract and lophirones B and C significantly (P < .05) reduced the viability of Ehrlich ascites carcinoma cells. There were concentration-dependent reduction in 4-nitro-o-aminophenylenediamine and benzo[a]pyrene-induced frame shift mutation as well as aflatoxin B1-induced base pair substitution by the extract and lophirones B and C. The extract and lophirones B and C concentration dependently scavenged DPPH radical, superoxide anion radical, hydrogen peroxide, hydroxyl radicals, and reduced ferric ion in the potassium hexacyanoferrate III reducing system. The results obtained from this study revealed that methanolic extract and lophirones B and C derived from Lophira alata stem bark posses anticancer, antimutagenic, and antioxidant activities, with lophirone C producing the best anticancer, antimutagenic, and antioxidant activities. The acclaimed anticancer activity of Lophira alata may be attributed to lophirones B and C.

Abstract
(+/-)-13-Hydroxy-10-oxo-trans-11-octadecenoic acid (13-HOA) is one of the lipoxygenase metabolites of linoleic acid (LA) from corn germ. Recently, we reported that this metabolite suppressed the expression of lipopolysaccharide-induced proinflammatory genes in murine macrophages by disrupting mitogen-activated protein kinases and Akt pathways. In this study, we investigated the inhibitory effects of 13-HOA on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in ears and skin, as well as tumor promotion in female ICR mice. Pretreatment with 13-HOA (1600 nmol) inhibited ear edema formation by 95% (P < 0.05) in an inflammation test and reduced tumor incidence and the number of tumors per mouse by 40 and 64% (P < 0.05 each), respectively, in a two-stage skin carcinogenesis model. Histological examinations revealed that it decreased epidermal thickness, the number of infiltrated leukocytes and cell proliferation index. Furthermore, 13-HOA (8-40 muM) suppressed TPA-induced anchorage-independent growth of JB6 mouse epidermal cells by 70-100%, whereas LA was virtually inactive. 13-HOA (40 muM) inhibited TPA-induced activator protein-1 transactivation but not extracellular signal-regulated kinase1/2 activation. Interestingly, 13-HOA (40 muM and 1600 nmol in JB6 cells and mouse skin, respectively) induced expression of programmed cell death 4 (Pdcd4), a novel tumor suppressor protein. To our knowledge, this is the first report of a food factor that is able to induce Pdcd4 expression. Collectively, our results indicate that 13-HOA may be a novel anti-inflammatory and antitumor chemopreventive agent with a unique mode of action.

Abstract
A total of 112 species of edible plants (122 samples) from Thailand were randomly collected, and their methanol extracts were screened for in vitro anti-tumor promoting activity using the inhibition test of Epstein-Barr virus (EBV) activation in Raji cells induced by 12-O-hexadecanoylphorbol-13-acetate (HPA, 40 ng/ml). It was found that 60% of these extracts inhibited EBV activation by 30% or more at a concentration of 200 mg/ml. Significantly, the ratio is markedly higher than that (26%) previously observed in common edible plants in Japan. Thus, physiological potentiality of edible Thai plants has been implied in terms of cancer chemoprevention.
