    • The present invention discloses a process for preparation of white curcumin from purified curcuminoids. The curcuminoids are obtained by solvent extraction and crystallization of dried turmeric powder. The autoclave is charged with ethyl acetate and the 95% purity curcuminoids mixture is added to and stirred for uniformity at room temperature. 5% (w/w) of 10% palladium carbon is added to the reaction mixture and allowed for hydrogenation in the presence of hydrogen gas at 2 lbps pressure and stirred continuously for 15 hours. Once the reaction is completed, the reaction mixture is filtered and washed with ethyl acetate. The ethyl acetate is distilled off and crude mass is stirred with water to obtain a solid precipitate. Finally, the solid obtained is filtered and dried to pale brown crystals of white curcumin. White curcumin is encapsulated with beta- cyclodextrin, which exhibited increased bioavailability. White curcumin also exhibited anti-oxidant and chemopreventive activities.
    • 本发明公开了一种从纯化姜黄素制备白姜黄素的方法。 姜黄素通过溶剂萃取和结晶的姜黄粉得到。 向高压釜中加入乙酸乙酯,并将95%纯度的姜黄色调混合物加入并在室温下搅拌均匀。 将5%(w / w)的10%钯碳加入到反应混合物中,并在氢气存在下以2l / s压力进行氢化并连续搅拌15小时。 一旦反应完成,将反应混合物过滤并用乙酸乙酯洗涤。 蒸馏除去乙酸乙酯,将粗物质与水一起搅拌,得到固体沉淀物。 最后,将得到的固体过滤并干燥成白色姜黄素的淡棕色晶体。 白色姜黄素用β-环糊精包封,其呈现出增加的生物利用度。 白姜黄素还具有抗氧化和化学预防作用。

    • The present invention provides non-peptide organic compounds that have a structure analogous to or reminiscent of the TMOF structure and have pesticidal activity. Particular pesticidal compounds/non-peptide TMOF analogs of the present invention have formula (I) wherein: X is selected from the group consisting of -CHCH-, -CH2CH2-, and -CC-; Z is selected from the group consisting of -OH, -NH2 and -OR6 wherein R6 is loweralkyl; n and m are each at last (I) and together total an integer from 2, 3 or 4 to 6, 8, 10 or 12; and R1, R2, R3, R4 and R5 are each independently selected from the group consisting of -H, -OH, halo, loweralkyl, and loweralkoxy; subject to the proviso that: a pair of R1 and R2, R2 and R3, or R3 and R4 on the phenyl ring may together represent -CR7=CR8-CR9=CR10-, to form with the phenyl ring illustrated above a naphthyl ring system, wherein R7, R8, R9 and R10 are each independently selected from the group consisting of -H, -OH, halo, loweralkyl, and loweralkoxy. Thus the present invention concerns pesticidal compounds that inhibit digestion in pests by terminating or otherwise blocking synthesis of digestive enzymes by activating a TMOF receptor (collectively referred to herein as "pesticidal compounds"). The pesticidal compounds and other compounds of the present invention are usefully employed in the control of pests, particularly insect pests such as mosquitoes, which ingest blood.
    • 本发明提供了具有与TMOF结构类似或令人想起的具有杀虫活性的结构的非肽有机化合物。 本发明的特定杀虫化合物/非肽TMOF类似物具有式(I),其中:X选自-CHCH - , - CH 2 CH 2 - 和-CC-; Z选自-OH,-NH 2和-OR 6,其中R 6是低级烷基; n和m各自为最后(I),并且总共为2,3或4至6,8,10或12的整数; 并且R 1,R 2,R 3,R 4和R 5各自独立地选自-H,-OH,卤素,低级烷基和低级烷氧基; 条件是:苯环上的一对R 1和R 2,R 2和R 3或R 3和R 4可以一起表示-CR 7 = CR 8 -CR 9 = CR 10 - ,与上述苯环形成萘基环系 其中R 7,R 8,R 9和R 10各自独立地选自-H,-OH,卤素,低级烷基和低级烷氧基。 因此,本发明涉及通过终止或以其它方式阻断消化酶的合成来抑制害虫消化的农药化合物,其通过激活TMOF受体(本文统称为“杀虫化合物”)。 本发明的杀虫化合物和其他化合物有效地用于控制害虫,特别是摄入血液的昆虫害虫如蚊子。
