摘要:A blue grain gene of Thinopyrum bessarabicum for regulating synthesis of anthocyanins and the use thereof, belonging to the technical field of plant genetic engineering. The blue grain gene of Thinopyrum bessarabicum is the TbMYB4J gene or TbMYC4J gene, the nucleotide sequence of the TbMYB4J gene being as shown in SEQ ID NO. 1, and the nucleotide sequence of the TbMYC4J gene being as shown in SEQ ID NO. 2 or SEQ ID NO. 3. For the first time, the two blue grain genes TbMYB4J and TbMYC4J for regulating the synthesis of anthocyanins are identified and obtained from the 4J chromosome of Thinopyrum bessarabicum, and influences of different combinations of the TbMYB4J and TbMYC4J genes on the accumulation of anthocyanins are defined by means of transient genetic transformation technology, thereby providing a basis and novel resources for color markers in molecular marker-assisted selection breeding and cross-breeding systems of wheat.

摘要:FtsZ, the bacterial analog of tubulin, is a promising new target for developing new antibiotics. It has been shown that polyphenols inhibit the GTPase activity of FtsZ, thereby inhibiting Z-ring formation during mitosis. The present invention provides novel polyphenols compounds, which can be accessed by the synthesis of dichamametin and 2′″-hydroxy-5″-benzylisouvarinol-B as described herein. These novel compounds are useful in treating infections, particularly infections caused by gram-positive organisms. Methods of preparing the inventive compounds are also provided. The compounds are prepared by the benzylation of pinocembrin or chrysin core structure. Pharmaceutical compositions and method of using the compounds to treat disease are also provided. These compounds may be screened for antimicrobial activity as well as other biological activities such as anti-neoplastic, anti-inflammatory, immunosuppressive, and cytotoxic activity.

摘要:The synthesis of the naturally occurring kaempferol glycoside SLO1O1-1, as well as analogs thereof, has been accomplished, as has its biochemical evaluation. SLO1O1-1 exhibits selective and potent p90 Rsk inhibitory activity at nanomolar concentrations without inhibiting the function of upstream kinases such as MEK, Raf, or PKC. The synthetic scheme of the invention verified the structural assignment of the natural product and has provided access to material sufficient for detailed biological evaluation.

摘要:Provided is a method of increasing lipid synthesis or accumulation in mammary epithelial cells (MECs) culture and optionally secretion therefrom. The method comprising contacting the MECs with an LXR agonist in the presence of a fatty acid to thereby increase lipid synthesis or accumulation and optionally secretion of lipids. Also provided is a method of producing synthetic fat globules, the method comprising: (a) isolating lipid droplets from cells in culture; (b) encapsulating the droplets with a lipid bilayer, thereby producing synthetic fat globules. Also provided are compositions produced thereby.
