anti-tumour and antioxidant activity of natural curcuminoids.	matural curcuminoids, curcumin, i, ii and iii isolated from turmeric (curcuma longa) were compared for their cytotoxic, tumour reducing and antioxidant activities. curcumin iii was found to be more active than the other two as a cytotoxic agent and in the inhibition of ehrlich ascites tumour in mice (ils 74.1%). these compounds were also checked for their antioxidant activity which possibly indicates their potential use as anti-promoters. the amount of curcuminoids (i, ii and iii) needed for 50% ...	1995	7621448
inhibition of human immunodeficiency virus type-1 integrase by curcumin.	curcumin (diferuloylmethane) is the yellow pigment in turmeric (curcuma longa l.) that is widely used as a spice, food coloring (curry) and preservative. curcumin exhibits a variety of pharmacological effects including antitumor, anti-inflammatory, and anti-infectious activities and is currently in clinical trials for aids patients. the effects of curcumin have been determined on purified human immunodeficiency virus type 1 (hiv-1) integrase. curcumin has an inhibitory concentration50 (ic50) for ...	1995	7748198
curcumin, a major component of food spice turmeric (curcuma longa) inhibits aggregation and alters eicosanoid metabolism in human blood platelets.	in traditional medicine, ayurveda, several spices and herbs are held to possess medicinal properties. earlier we have reported that extracts from several spices, including turmeric, inhibit platelet aggregation and modulate eicosanoid biosynthesis. due to their eicosanoid-modulating property, it was suggested that the spices may serve to provide clues to drugs directed to arachidonic acid (aa) pathway enzymes as pharmacological targets. curcumin, a major component of turmeric, inhibited platelet ...	1995	7784468
inhibition of tumor necrosis factor by curcumin, a phytochemical.	curcumin, contained in the rhizome of the plant curcuma longa linn, is a naturally occurring phytochemical that has been used widely in india and indonesia for the treatment of inflammation. the pleiotropic cytokine tumor necrosis factor-alpha (tnf) induces the production of interleukin-1 beta (il-1), and, together, they play significant roles in many acute and chronic inflammatory diseases. they have been implicated in the pathogenesis of intracellular parasitic infections, atherosclerosis, aid ...	1995	7786295
chemoprevention of colon carcinogenesis by dietary curcumin, a naturally occurring plant phenolic compound.	human epidemiological and laboratory animal model studies have suggested that nonsteroidal antiinflammatory drugs reduce the risk of development of colon cancer and that the inhibition of colon carcinogenesis is mediated through the alteration in cyclooxygenase metabolism of arachidonic acid. curcumin, which is a naturally occurring compound, is present in turmeric, possesses both antiinflammatory and antioxidant properties, and has been tested for its chemopreventive properties in skin and fore ...	1995	7812955
