Objective: The aim of the present investigation was to determine the in vitro antioxidant and anticancer activity of the ethanol extract of Ulva lactuca L. Methods: The present study was to investigate the antioxidant and anticancer activity of U. lactuca L. The extract of U. lactuca L. was extracted by ethanol and subject to analysis. An in vitro antioxidant activity of the ethanol extract of U. lactuca L. was performed by 1, 1-diphenyl-2-picrylhydrazyl free radical scavenging assay. Simultaneously anticancer activity was also performed using blood cancer (MOLT-3) cell line, and the species showed a strong selective cell proliferation inhibition of the cancer cell line. Results: The scavenging activity was measured and determined to be 78.5%. This might be due to high polyphenolic compounds and flavonoid contents of the extract, which showed maximum growth inhibition of 74.4%. Conclusion: Thus, the study concludes that the constituents of seaweeds can act as potent in treating various diseases and can be used as an alternative for therapeutic treatment.

 Objective: In recent years, herbal plants have been got more attention due to their diverse presence of phytochemicals and its biological properties. Hepatocellular carcinoma is one of the major worldwide problems primarily caused by hepatitis B and C virus infection. End-stage liver cancer treatment options are limited, thus requiring expensive liver transplantation which is not available in many countries.Methods: In the present study, the Mucuna pruriens seed extract was analyzed for phytochemicals, antioxidant activity, total phenols, and total flavonoids content. The seed extract was further analyzed for its anticancer activity by culturing liver cancer cell line. The above protocols were done by standard methods.Results: The seed extract of M. pruriens revealed more number of phytochemicals in different organic solvents. 1,1- Diphenyl- 2- picrylhydrozyl scavenging activity of plant extract was more in ethanol extract (98.051±0.547) among all other solvents. The total phenols and flavonoids content in ethanol extract were 46.442±0.353 mg gallic acid equivalent/g and 2.254±0.647 mg - quercetin equivalent /g, respectively. IC50 value of 3-(4, 5-dimethythiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) analysis of Hep-2 cell line was 150 (μg/ml).Conclusion: The present study revealed about the phytochemical contents and antioxidant potential of M. pruriens seeds. Further, the MTT analysis proved that the seed extract was effective against cancer cells and also used to treat many diseases.

A series of eight quinoline-thiazole hybrid-bearing diazenylsulfonamides, 4a-4h, were synthesized and characterized by UV-Vis, FT/IR, 1H NMR and lC-MS. These compounds were formed when two prepared intermediate precursors of Schiff-base compounds, (E)-N-((2-chloroquinolin-3-yl)methylene)-4phenylthiazol-2-amine (3a) and (E)-N-((2-chloroquinolin-3-yl)methylene)-4-chlorophenylthiazol-2-amine (3b) were converted to the corresponding diazenyl compounds 4a-4h by treating and coupling with the individual diazonium salts of sulfa-drugs. The results of in vitro cytotoxic activity of the synthesized compounds in two cancer cell lines MCF 7 (human breast cancer cell line) and K562 (myelogenousleukemia cell line) have shown the IC50 values as given: 4b against MCF 7 19.52 and against K562 20.55µM; 4d against MCF 7 15.96 and against K562 13.05µM. Moreover, the compound 4-(((Z)-(2-chloroquinolin-3yl)(4-phenylthiazol-2-ylimino)methyl)diazenyl)benzenesulfonic acid (4d) induced maximum percentage of apoptosis. Furthermore, the in vitro antioxidant activity study revealed that among all the synthesized compounds, compound 4d has an excellent radical scavenging effect. Molecular docking was additionally performed to investigate the binding affinity of H-bonding interaction of synthesized compounds with a targeted enzyme and to compare it with the anticancer drugs, dasatinib, bosutinib and dacarbazine.

A series of several diazenyl Schiff base derivatives were designed and synthesized through azo coupling of diazotised primary amines with the novel synthesized Schiff base ligand (E)-N-((2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine. All the synthesized compounds have been analysed by different spectral techniques such as elemental analysis, 1H NMR, FT-IR, UV-Vis and LC-MS for their structural confirmation. The above conjugates have been studied for their solvent effects by treating them with different solvents. The results of in vitro cytotoxic study of the synthesized compounds against MCF 7 (human breast cancer cell line) and K562 (Chronic Myeloid Leukemia cell line) revealed that some of the compounds show cytotoxic effect. However, the compounds (NZ)-N-(((4-bromo-3-methylphenyl) diazenyl) (2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine: (5d) and 4-(((Z)-(2-chloroquinolin-3- yl)(4-phenylthiazol-2-ylimino)methyl)diazenyl)phenol (5e) showed potent cytotoxic activity in comparison to other compounds against MCF 7. Corroborating the results of anticancer activity, it is found to be observed that the compound 4- (((Z)- (2-chloroquinolin-3-yl) (4-phenylthiazol-2-ylimino)methyl) diazenyl) phenol (5e) showed excellent anticancer activity against MCF 7, which is further justified by the apoptosis study through Annexin V-FITC/PI analysis.

Synthetic Approaches

Polyether ionophores represent a group of natural lipid-soluble biomolecules with a broad spectrum of bioactivity, ranging from antibacterial to anticancer activity. Three seem to be particularly interesting in this context, namely lasalocid acid, monensin, and salinomycin, as they are able to selectively target cancer cells of various origin including cancer stem cells. Due to their potent biological activity and abundant availability, some research groups around the world have successfully followed semi-synthetic approaches to generate original derivatives of ionophores. However, a definitely less explored avenue is the synthesis and functional evaluation of their multivalent structures. Thus, in this paper, we describe the synthetic access to a series of original homo- and heterodimers of polyether ionophores, in which (i) two salinomycin molecules are joined through triazole linkers, or (ii) salinomycin is combined with lasalocid acid, monensin, or betulinic acid partners to form ‘mixed’ dimeric structures. Of note, all 11 products were tested in vitro for their antiproliferative activity against a panel of six cancer cell lines including the doxorubicin resistant colon adenocarcinoma LoVo/DX cell line; five dimers (14–15, 17–18 and 22) were identified to be more potent than the reference agents (i.e., both parent compound(s) and commonly used cytostatic drugs) in selective targeting of various types of cancer. Dimers 16 and 21 were also found to effectively overcome the resistance of the LoVo/DX cancer cell line.

(1) Background: Extensive research has focused on flavan-3-ols, but information about the bioactivities of green tea flavonols is limited. (2) Methods: In this study, we investigated the antioxidative, anti-inflammatory, and anticancer effects of flavonol glycosides and aglycones from green tea using in vitro cell models. The fractions rich in flavonol glycoside (FLG) and flavonol aglycone (FLA) were obtained from green tea extract after treatment with tannase and cellulase, respectively. (3) Results: FLG and FLA contained 16 and 13 derivatives, respectively, including apigenin, kaempferol, myricetin, and quercetin, determined by mass spectrometry. FLA exhibited higher radical-scavenging activity than that of FLG. FLG and FLA attenuated the levels of intracellular oxidative stress in neuron-like PC-12 cells. The treatment of RAW 264.7 murine macrophages with FLG and FLA significantly reduced the mRNA expression of inflammation-related genes in a dose-dependent manner. Furthermore, FLG and FLA treatments decreased the viability of the colon adenoma cell line DLD-1 and breast cancer cell line E0771. Moreover, the treatment with FLG or FLA combined with paclitaxel had synergistic anticancer effects on the DLD-1 cell line. (4) Conclusions: Flavonols from green tea exerted beneficial effects on health and may be superior to flavan-3-ols.
