Flavonoid Dimers and Methods of Making and Using Such

Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over-expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.

Sorghum aluminum tolerance gene, SbMATE

The major aluminum tolerance gene, the SbMATE gene, encodes a root citrate efflux transporter that is Al-inducible at the level of gene transcription and is also Al-activated at the level of protein function. High level of expression of the SbMATE gene and the protein was found in roots. SbMATE orthologs with high degree of sequence homology were found in other higher plants, including rice. Successful transformation of Arabidopsis provides strong evidence that SbMATE can work across species to enhance tolerance to Al in other important crops grown in localities worldwide where Al3+ cations are present in acid soils and are toxic to plants.

Method for increasing yield of L-alanyl-L-glutamine from recombinant escherichia coli

The invention discloses a method for improving activity of an L-alanyl-L-glutamine biosynthesis system containing recombinant DNA. A recombinant plasmid of the recombinant escherichia coli comprises an amino-acid ester acyltransferase encoding gene (SAET) which can catalyze L-glutamine and L-alanine methyl ester hydrochloride to generate L-alanyl-L-glutamine, and a multidrug efflux transporter protein encoding gene (ydeE) which can transporting L-alanyl-L-glutamine outside cells from cells, and due to co-expression of the two encoding genes, stability of a bacterium can be effectively improved, and the yield and the transformation rate of the bacterium can be increased. The recombinant plasmid is obtained by recombining SAET and ydeE with the same plasmid, or by co-transforming two recombinant plasmids with different resistances of two genes respectively. The yield of L-alanyl-L-glutamine of the recombinant bacterium can be increased by 3.33 times when compared with a conventional yield.

Pharmaceutical oral dose formulation and composition of matter

An apparatus and method for formulating low solubility, low permeability and / or p-glycoprotein efflux transporter substrate drugs or herbal extracts for increased intestinal absorption. The method utilizes a supercritical fluid, such as carbon dioxide to complex a low solubility, low permeability and / or p-glycoprotein efflux transporter substrate drug or herbal extract, the p-glycoprotein inhibitors quercitin and piperine, with a carbohydrate. The result is a micro-emulsion of the drug or herbal extract which has both higher solubility and permeability than if dosed alone; as well as resistance to p-glycoprotein mediated efflux, once absorbed into the intestinal lumen.
