He, Jiahong published the artcileInsight into the corrosion inhibition property of Artocarpus heterophyllus Lam leaves extract, Computed Properties of 56317-21-6, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2021), 260-270, database is CAplus.

In this work, the method (water extraction way) was uesd to acquire Artocarpus heterophyllus Lam leaves extract (AHLLE). We refer to the relevant references on the composition of Artocarpus heterophyllus Lam leaves and perform Fourier IR spectroscopy anal. for AHLLE. It can be concluded that AHLLE contains 2-(2,4-dihydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one (DPD), (2R,3R)-2-(2,4-dihydroxyphenyl)-3 ,5,7-trihydroxychroman-4-one (DPT), 3-(4-hydroxyphenyl)acrylic acid (HPT), and 5-(6-hydroxybenzofuran-2-yl)benzene-1,3-diol (HBB). Quantum chem. calculations (QCC) data and mol. dynamics (MD) simulations results show that DPD, DPT, HPT, and HBB all have the potential of excellent corrosion inhibitors. Scanning electron microscope (SEM) results and at. force microscope (AFM) test results show that after adding AHLLE to H2SO4 environment, the copper surface is still correspondingly flat. In addition, the results of electrochem. experiments indicate that the AHLLE is 500 ppm, the anti-corrosion efficiency obtained from electrochem. impedance spectroscopy data can reach 97.3%. With the temperature augments to 313 K, the corrosion inhibition nature of AHLLE can still be maintained to 97%. AHLLE is adsorbed onto the Cu surface and belongs to Langmuir monolayer adsorption.

Zhou, Siqi published the artcileA chondroprotective effect of moracin on IL-1β-induced primary rat chondrocytes and an osteoarthritis rat model through Nrf2/HO-1 and NF-κB axes, Product Details of C14H10O4, the publication is Food & Function (2020), 11(9), 7935-7945, database is CAplus and MEDLINE.

Osteoarthritis (OA) is a common joint disease characterized by cartilage degeneration and inflammation. Although moracin is known to play a role in anti-inflammation and anti-oxidation in several inflammatory diseases, its anti-inflammatory effect on OA remains largely unknown. Therefore, in order to explore the role of moracin in OA, we investigated the anti-inflammatory effect of moracin on interleukin (IL)-β-induced rat chondrocytes in vitro and surgically induced OA rat models in vivo. Rat chondrocytes were pretreated using moracin (0, 5, 10, 15μmol L-1) and then stimulated with IL-β (10 ng ml-1). Results showed that moracin reduced the expression of IL-1β-induced nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2 in both rat chondrocytes and cell culture supernatants. Besides, IL-1β-induced degradation of aggrecan and collage II, and the high expression of matrix metalloproteinase-13 (MMP-13) and a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS)-5 were also reversed by moracin. Moreover, moracin inhibited the translocation of p65 from the cytoplasm to nucleus induced by IL-1β and activated the Nrf2/HO-1 signaling pathway in chondrocytes. In OA rat models, moracin prevented cartilage of rats from destruction. All these findings above indicated that moracin could be a potentially effective drug for treating OA.

Ma, Fang published the artcileAnti-HSV activity of Kuwanon X from Mulberry leaves with genes expression inhibitory and HSV-1 induced NF-κB deactivated properties, Quality Control of 56317-21-6, the publication is Biological & Pharmaceutical Bulletin (2016), 39(10), 1667-1674, database is CAplus and MEDLINE.

Six stilbene derivatives isolated from Mulberry leaves including Kuwanon X, Mulberrofuran C, Mulberrofuran G, Moracin C, Moracin M 3′-O-b-glucopyranoside and Moracin M were found to have antiviral effects against herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) at different potencies except for Mulberrofuran G. Kuwanon X exhibited the greatest activity against HSV-1 15577 and clin. strains and HSV-2 strain 333 with IC50 values of 2.2, 1.5 and 2.5μg/mL, resp. Further study revealed that Kuwanon X did not inactivate cell-free HSV-1 particles, but inhibited cellular adsorption and penetration of HSV-1 viral particles. Following viral penetration, Kuwanon X reduced the expression of HSV-1 IE and L genes, and decreased the synthesis of HSV-1 DNA. Furthermore, it was demonstrated that Kuwanon X inhibited the HSV-1-induced nuclear factor (NF)-κB activation through blocking the nuclear translocation and DNA binding of NF-κB. These results suggest that Kuwanon X exerts anti-HSV activity through multiple modes and could be a potential candidate for the therapy of HSV infection.

Ha, Manh Tuan published the artcileChalcone derivatives from the root bark of Morus alba L. act as inhibitors of PTP1B and α-glucosidase, Category: benzofurans, the publication is Phytochemistry (Elsevier) (2018), 114-125, database is CAplus and MEDLINE.

As part of our continuing research to obtain pharmacol. active compounds from Morus alba L. (Moraceae), four Diels-Alder type adducts (DAs) [morusalbins A-D], one isoprenylated flavonoid [albanin T], together with twenty-one known phenolic compounds were isolated from its root bark. The chem. structures were established using NMR, MS, and ECD spectra. The DAs including morusalbins A-D, albasin B, macrourin G, yunanensin A, mulberrofuran G and K, and albanol B exhibited strong inhibitory activities against both protein tyrosine phosphatase 1B (PTP1B) (IC₅₀, 1.90-9.67 μM) and α-glucosidase (IC₅₀, 2.29-5.91 μM). In the kinetic study, morusalbin D, albasin B, and macrourin G showed noncompetitive PTP1B inhibition, with K_i values of 0.33, 1.00, and 1.09 μM, resp. In contrast, these DAs together with yunanensin A produced competitive inhibition of α-glucosidase, with K_i values of 0.64, 0.42, 2.42, and 1.19 μM, resp. Furthermore, mol. docking studies revealed that these active DAs have high affinity and tight binding capacity towards the active site of PTP1B and α-glucosidase.

Jeong, Seong Hun published the artcileTyrosinase Inhibitory Polyphenols from Roots of Morus lhou, Application In Synthesis of 56317-21-6, the publication is Journal of Agricultural and Food Chemistry (2009), 57(4), 1195-1203, database is CAplus and MEDLINE.

Twelve polyphenols (1-12) possessing tyrosinase inhibitory properties were isolated from the methanol (95%) extract of Morus lhou. The isolated compounds consisted of four flavanones (1-4), four flavones (5-8), and four phenylbenzofurans (9-12). Moracin derivative 12 proved to be new a compound which was fully characterized. Compounds 1-12 were evaluated for both monophenolase and diphenolase (the two steps catalyzed by tyrosinase) inhibition to identify the structural characteristics required for mushroom tyrosinase inhibition. We observed that all parent compounds (1, 5, and 9) possessing an unsubstituted resorcinol group were highly effective inhibitors of monophenolase activity (IC₅₀ values of 1.3, 1.2, and 7.4 μM). The potency of the inhibitors diminished with alkyl substitution on either the aromatic ring or the hydroxyl functions. Interestingly, flavone 5 was shown to possess only monophenolase inhibitory activity, but flavanone 1 and phenylbenzofuran 9 inhibited diphenolase as well as monophenolase significantly. The inhibitory mode of these species was also dependent upon the skeleton: phenylbenzofuran 9 manifested a simple competitive inhibition mode for monophenolase and diphenolase; on the other hand flavanone 1 (monophenolase, k₃ = 0.1966 min^-1 μM^-1, k₄ = 0.0082 min^-1, and K_i^app = 0.0468 μM; diphenolase, k₃ = 0.0014 min^-1 μM^-1, k₄ = 0.0013 min^-1, and K_i^app = 0.8996 μM) and flavone 5 both showed time-dependent inhibition against monophenolase. Compound 1 operated according to the simple reversible slow binding model whereas compound 5 operated under the enzyme isomerization model.

Royer, Mariana published the artcileEfficacy of Bagassa guianensis Aubl. extract against wood decay and human pathogenic fungi, Product Details of C14H10O4, the publication is International Biodeterioration & Biodegradation (2012), 55-59, database is CAplus.

Extractives that provide natural resistance to Bagassa guianensis Aubl. heartwood were examined Soil-bed tests showed that the B. guianensis heartwood resistance was significantly reduced after Et acetate extraction, whereas methanol and especially water extractions improved the resistance. The Et acetate extract was submitted to a bioguided fractionation, and fractions were tested against one wood-destroying fungal strain (Pycnoporus sanguineus) and two human pathogenic fungal strains (Candida glabrata (yeast) and Trichophyton rubrum (filamentous dermatophyte)). Fraction F7, which exhibited the strongest antifungal activity, was subsequently fractionated by high performance liquid chromatog. (HPLC). Six previously described compounds were isolated. Although the two moracins, 6-O-methyl-moracin N (3) and moracin N (4) were the most active against fungal strains with MIC values between 4 and 16 μg ml^-1, the isolated compounds showed less or equivalent antifungal activity than the initial fraction. Possible synergism between compounds 3 and 4 and other secondary metabolites have been hypothesized. Our study demonstrated that this extract as a whole might be used as a wood preservation or antimycotic product.
