Datta, Hemanta Kumar published the artcileStructural elucidation of a heteropolysaccharide from the wild mushroom Marasmiellus palmivorus and its immune-assisted anticancer activity, Related Products of alcohols-buliding-blocks, the main research area is Marasmiellus heteropolysaccharide structure immunity anticancer activity; Anticancer activity; Heteropolysaccharide; Immunomodulation; Macrofungi; Marasmiellus palmivorus; Structure.

The biol. activity of macrofungal polysaccharides (MFPS) depends on their structural features and is a topic of keen interest for researchers since long time. We report a water-soluble macrofungal heteropolysaccharide (MFPS1) with a molar weight of ∼145,000 g/mol, obtained through alkali extraction, of the wild mushroom, Marasmiellus palmivorus, with significant immunomodulatory properties. In cancer, after the induction of metastasis, the anticancer immune system becomes unresponsive. By studying cytokine secretion and immune phenotyping, it was observed that MFPS1 reactivated the anticancer immune surveillance system. MFPS1 executed T-cell maturation and activation via M1Φ; and also stimulated natural killer (NK) cell and B-cell population. The entire immune activation pathway corroborates its anticancer activity. The RP-HPLC anal. of hydrolyzed MFPS1 showed arabinose, glucose, galactose, and mannose as monosaccharide units. The proposed structure of repeating unit was established from methylation anal., 1D- and 2D NMR study, HR-MS and MALDI-TOF MS anal.

Yu, Juan published the artcileRelationship between structural properties and antitumor activity of Astragalus polysaccharides extracted with different temperatures, SDS of cas: 59-23-4, the main research area is Astragalus polysaccharide structure antitumor temperature; Antitumor activity; Astragalus membranaceus polysaccharides; Structural characterization.

This study investigated the effects of different temperatures on structural characterization and antitumor activity of polysaccharides from Astragalus membranaceus. APS4 and APS90 were extracted at 4°C and 90°C, resp., and purified by Sephadex G-200 column. APS4-90 were obtained from APS4 after treatment at 90°C for 6 h. MTT results showed that APS4 possessed the highest inhibitory effects on MGC-803, A549 and HepG2 cells. HPGPC anal. showed that the average mol. weights of these polysaccharides were approx. 1.5 × 106 Da, while the asym. peak of APS4-90 suggested heat degradation and configuration changes of APS4. GC, NMR and methylation results showed that these three polysaccharides had similar monosaccharide components (mainly contain glucose), and their backbones were composed of (1→2)-α-D-Glcp. However, APS4 showed higher content of (1→2,6)-α-D-Glcp compared to APS4-90 and APS90, which indicated that higher branched degree would be responsible for the stronger in vitro antitumor activity in APS4. These results were also confirmed by sp. rotation and SEM anal. Our study suggested that APS4 had the potential application for cancer treatment.

Dong, Xiao-dan published the artcileA novel polysaccharide from Castanea mollissima Blume: Preparation, characteristics and antitumor activities in vitro and in vivo, Name: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is antitumor castanea polysaccharide CMP90 proliferation apoptosis cytokines immune cells; Antitumor; Castanea mollissima Blume; Characteristics; Polysaccharide.

A new water-soluble polysaccharide, CMP90, with a mol. weight of 23.9 kDa was isolated from Castanea mollissima Blume and the preliminary structural characteristics and antitumor effects of CMP90 in vitro and in vivo were investigated in the research. CMP90 consists of arabinose, galactose, glucose, xylose and mannose (molar ratio: 0.08:0.11:5.14:0.12:0.08) with α- and β-anomeric units. The results of in vitro experiments indicated that CMP90 exhibited a significant inhibitory effect on the proliferation of HL-60 cells with typical apoptotic characteristics by inducing cell cycle arrested at G1/M phase. Addnl., the results in vivo suggested CMP90 was able to inhibit the growth of S180 solid tumors via protecting immune organs, improving the levels of serum cytokines (TNF-α, IL-2 and IFN-γ), enhancing the activities of immune cells (macrophages, lymphocytes and NK cells) and inducing cell apoptosis or death. Taken together, these combined data clearly indicated that CMP90 may be used as a potential candidate agent for cancer therapy.

Takemoto, Hiroyasu published the artcilePolymeric modification of gemcitabine via cyclic acetal linkage for enhanced anticancer potency with negligible side effects, SDS of cas: 22483-09-6, the main research area is anticancer drug gemcitabine polymer conjugate pH responsive nanoparticle stability; Drug delivery system; Gemcitabine; Polymers; Side effects; pH-responsiveness.

Gemcitabine (GEM) is a powerful anticancer drug for various cancers. However, the anticancer efficacy and the side effects should be addressed for effective therapeutics. To this end, we created a GEM-conjugated polymer (P-GEM) based on cyclic acetal linkage as a delivery carrier of GEM. The obtained P-GEM stably conjugated GEM at physiol. pH (i.e., bloodstream), but released GEM in response to acidic environments such as endosome/lysosome. After systemic administration of P-GEM for mice bearing s.c. tumors, it achieved prolonged blood circulation and enhanced tumor accumulation relative to free GEM system. In addition, the polymer-drug conjugate structure of P-GEM realized effective distribution in the tumor tissues toward the induction of apoptosis in most areas of the tumor sites. Of note, the mol. design of P-GEM achieved minimal accumulation in normal tissues, resulting in negligible GEM-derived adverse effects (e.g., gastrointestinal toxicity and hematotoxicity). Ultimately, even four times smaller dose of P-GEM on a GEM basis realized comparable/higher tumor growth suppression effect for two distinct pancreatic tumor models, compared to free GEM system. The obtained results suggest the huge potential of the present design of GEM-conjugated polymer for anticancer therapeutics.

Wu, Pu published the artcileBioactivity-guided discovery of quality control markers in rhizomes of Curcuma wenyujin based on spectrum-effect relationship against human lung cancer cells, Recommanded Product: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Curcuma wenyujin rhizome quality control human lung cancer cell; Curcuma wenyujin; bioactive compounds-based fingerprint; quality control; spectrum-effect relationship.

Due to the diversity of the ingredients, the complexity of the mechanism of action, the uncertainty of the effective ingredients, coupled with the multiple species and multiple growing areas, the quality control (QC) of Traditional Chinese Medicines (TCMs) is challenging. Discovering and identifying effective compounds from the complex extracts of TCMs and then establishing a scientific QC method is the key to the holistic QC of TCMs. To develop an anti-lung-cancer-guided spectrum-effect relationship approach for the discovery of QC markers of the rhizome of Curcuma wenyujin (WEZ) and establish a bioactive compounds-based holistic QC method. The chem. profiling of the volatile oil (WVO) from 42 batches of WEZ collected from different growing areas was performed by GC-MS. The anti-lung cancer activity of different WVO samples was determined by CCK-8 assay against human lung cancer cells (A549). The apoptosis and cell cycle anal. under different concentrations of WVO were detected by flow cytometry. SIMCA-P software was used to perform multivariate statistical anal. on the chem. composition of different WVO samples and to find the different components. Active compounds were screened using a PLSR model of the spectrum-effect relationship. Bioactive compounds-based fingerprint and quantification of the leading bioactive compounds were developed by GC-MS and GC-FID, resp. Seventy-eight compounds were detected in WVO and 54 were successfully identified. The multivariate statistical anal. uncovered that WVO components and the anti-A549 activity of WVO at the concentration of 60 nl/mL differ greatly according to the origin of the plant. The WVO at the concentration of 60 nl/mL (IC50) increased A549 cells apoptosis significantly with late and early apoptosis of 15.61% and 7.80%, and the number of cells in the G2/M phase were also increased significantly under this concentration The spectrum-effect relationship anal. revealed that 44 compounds were pos. correlated with their activities, and the result was verified by A549 cell viability assay. Sixteen pos. correlated compounds were further selected as QC markers according to their relative amount > 0.5% and anticancer activity. Finally, the 16 QC markers-based GC-MS fingerprint was established to holistically control the quality of WEZ, and a GC-FID method was developed for the quantification of leading bioactive compounds, β-elemene and β-caryophyllene. Based on an anti-lung-cancer-guided spectrum-effect relationship approach, the bioactive compounds-based holistic QC method was successfully developed for WEZ, which could provide a valuable reference for the QC of TCMs.

El-Garawani, Islam published the artcileFoeniculum Vulgare and Pelargonium Graveolens Essential Oil Mixture Triggers the Cell Cycle Arrest and Apoptosis in MCF-7 Cells, Safety of 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is Foeniculum Pelargonium essential oil breast cancer cell cycle apoptosis; Fennel; GC-MS; MCF-7; anticancer; apoptosis; geranium..

This study aimed to evaluate the anticancer mechanism of fennel and geranium oils combined treatment on MCF-7 cells. The GC-MS method for essential oil characterization as well as the in vitro cytotoxicity, morphol. changes, real-time PCR and immunocytochem. investigation for apoptosis-related markers, in addition, to flow cytometric cell cycle distribution anal. were done. The major constituents of both essential oils were anethole (55.33%) and estragole (11.57%) for fennel essential oil. However, cintronellol (34.40%) and geraniol (8.67%) were identified in geranium oil. The results revealed an IC50 of 220±5.7 and 60±2.1μg/mL for fennel and geranium oils, resp. The mechanistic anticancer properties were investigated throughout the 70, 50, and 25μg/mL of oils mixture The marked apoptotic morphol. and the flow cytometric cell cycle distribution anal. in addition to the levels of apoptosisrelated makers such as p53, caspase-3, mir-21, mir-92a, Bcl-2, and ki-67 confirmed that fennel and geranium oils combination induced cell cycle arrest and apoptosis in MCF-7 cells. Moreover, the oils mixture did not exert any significant (P<0.01) toxicity on normal human peripheral blood lymphocytes in vitro. The findings showed that the mixture of oils exerted selective cytotoxicity towards MCF-7 cells through induction of cell cycle arrest and apoptosis which may be triggered by the synergistic effect between the active ingredients of fennel and geranium oils.

Li, Ying published the artcilePurification, characterization and anti-tumor activities of polysaccharides from Ecklonia kurome obtained by three different extraction methods, Formula: C6H12O6, the main research area is Ecklonia breast cancer cell polysaccharide extraction antitumor; Antitumor activity; Ecklonia kurome; Extraction methods; Polysaccharides.

To investigate and compare the effects of different extraction methods on the structure and anti-tumor activity of Ecklonia kurome polysaccharides (EP), three techniques, namely hot water extraction (HW), ultrasonic-assisted extraction (UA) and enzyme-assisted extraction (EA), were used to extract EP, and three crude EPs were purified by DEAE-cellulose and gel filtration chromatog. The significant antitumor active components in each method were screened by MTT assay and named as HW-EP5, UA-EP4 and EA-EP3, resp. The mol. weight, FT-IR assay and NMR showed that HW-EP5, UA-EP4 and EA-EP3 were pyran polysaccharides with a mol. weight of 14,466, 15,922 and 16,947 Da, resp. HW-EP5 contained the most monosaccharides and the highest content of sulfate and uronic acid. HW-EP5 had an even and smooth sheet-like appearance, while UA-EP4 and EA-EP3 exhibited irregular and rough fragments. All three polysaccharides can inhibit the migration of human breast cancer cells (MCF-7) and promote its apoptosis. All three polysaccharides promoted caspase activity during apoptosis. HW-EP5 and UA-EP4 up-regulated the expression of proapoptotic proteins Bax and p53, while EA-EP3 only up-regulated the expression of p53. These exptl. results indicate that Ecklonia kurome polysaccharides, especially HW-EP5, have great potential as a natural medicine for the treatment of breast cancer.

Tian, Wen-Tan published the artcileStructural characterization of an acid polysaccharide from Pinellia ternata and its induction effect on apoptosis of Hep G2 cells, SDS of cas: 59-23-4, the main research area is Pinellia acid polysaccharide cell apoptosis induction effect; Antitumor activity; Pinellia ternata polysaccharide; Structure.

In the present study, a polysaccharide fraction (PTP) was isolated and purified from the tubers of Pinellia ternata. We researched its structure and anti-tumor activity, and further studied its mol. mechanism of inducing apoptosis of Hep G2 cells. The results indicated that PTP was an acid heteropolysaccharide and the average mol. weight of PTP identified by HPGPC was 3.06 x 106 Da. Ion chromatog. (IC) determined that PTP was mainly composed of Ara:Gal:Glu:Man:GlcA:GalA in a molar ratio of 6.98:16.56:7.25:2.04:1:4.16. Combined with the results of FT-IR and NMR spectroscopy, it was found that PTP is a pyranose containing a-configuration and β-configuration, mainly consist of β-D-Gal, a-D-Glu, a-D-Ara and β-D-Man. By analyzing the results of MTT, cell cycle, Annexin V-FITC/PI double staining and cell morphol. observation, we concluded that PTP induced dose-dependent apoptosis of Hep G2 cells via S phase arrest. In addition, mitochondrial membrane potential detection and Western blot further indicated that PTP was capable of inducing apoptosis in Hep G2 cells through an endogenous mitochondria-mediated apoptotic pathway.
