P Kolodziejczyk et al.
Free radical biology & medicine, 5(1), 13-25 (1988-01-01)
Ambient temperature incubation of the anticancer agent mitoxantrone with horseradish peroxidase and hydrogen peroxide converts it into a hexahydronaphtho[2,3-f]quinoxaline-7,12-dione in which one side chain has cyclized to the chromophore. The structure of this cyclic metabolite was secured by independent synthesis.

Cancer research, 46(7), 3375-3377 (1986-07-01)
We described recently a modified charcoal-gelatin (MCG) assay for measuring progesterone receptor activity in low-protein cytosols. We showed that pre-mixing of gelatin with sample cytosols (final gelatin concentration 0.1%) and removal of unbound steroid by a 1% charcoal suspension with

Protoapigenone, a natural flavonoid possessing an unusual p-quinol moiety on its B-ring, is a novel prospective anticancer agent with low toxicity that is currently in development. The first economical, one-step synthesis of protoapigenone from apigenin is described on up to
Z Piskornik et al.
Plant physiology, 50(1), 176-182 (1972-07-01)
The "bound auxin" of Zea mays, first described by Berger and Avery (Amer. J. Bot. 1944; 31: 199-203) has been purified and partially characterized. It is an indole-3-acetic acid-containing, high molecular weight, lipophilic cellulosicglucan. The indole-3-acetic acid is in ester
Y Jiang et al.
International journal of food sciences and nutrition, 61(4), 346-356 (2010-05-15)
Various vegetables were investigated for antioxidant activities in two assays, namely, inhibition of lysis of erythrocytes induced by peroxyl radicals and inhibition of lipid peroxidation. The lotus (Nelumbo nucifera Gaertn) rhizome showed the strongest antioxidant activity in both assays. The
Hui Shao et al.
Macromolecular bioscience, 9(5), 464-471 (2008-12-02)
Polyacrylate glue protein analogs of the glue secreted by Phragmatopoma californica, a marine polycheate, were synthesized with phosphate, primary amine, and catechol sidechains with molar ratios similar to the natural glue proteins. Aqueous mixtures of the mimetic polyelectrolytes condensed into
Min Xu et al.
Biology of reproduction, 81(3), 587-594 (2009-05-29)
In vitro ovarian follicle cultures may provide fertility-preserving options to women facing premature infertility due to cancer therapies. An encapsulated three-dimensional (3-D) culture system utilizing biomaterials to maintain cell-cell communication and support follicle development to produce a mature oocyte has
The source, composition and flux of polycyclic aromatic hydrocarbons in sediments of the river Derwent, Derbyshire, U.K.
Evans, K.M., et al.

Chlorogenic acid (CGA) or 5-caffeoylquinic acid, was found to be the dominant phenolic compound in leaves of Etlingera elatior (Zingiberaceae). The CGA content of E. elatior leaves was significantly higher than flowers of Lonicera japonica (honeysuckle), the commercial source. In
Suman B Sharma et al.
Journal of medicinal food, 14(4), 353-359 (2011-03-05)
Diabetes is accompanied by lipid abnormalities, which contribute significantly to cardiovascular morbidity and mortality in diabetic patients. We previously demonstrated the potent antihyperglycemic activity of the active principle (fraction II from Sephadex LH 20 chromatography [LH II]) isolated from ethanolic
