  • Patent number: 11572382
    Abstract: The invention relates to novel camptothecin derivatives and their applications, tumor cell growth inhibitors, ternary complexes, and a method for improving the solubility of the camptothecin derivatives. The camptothecin derivatives are prepared by modifying the substance shown as Formula I with glycosylated triazole at position R3. In the structure shown as Formula I, R1 represents H, C1-10 alkyl, C1-10 alkyl-D or C1-10 haloalkyl; R2 represents H, CH2N(CH3)2 or CH2N(CD3)2; and R4 represents or H, wherein X represents N, O or S; and L represents polypeptide, C1-20 linear alkyl or derivatives thereof, C1-20 linear or branched acyl derivatives, C2-100 ethylene glycol or derivatives thereof. The camptothecin derivatives have high solubility, the anticancer drugs prepared from them have the advantages of wide anticancer spectrum and high safety, and have in vivo anticancer activity higher than irinotecan hydrochloride.

  • Patent number: 10085470
    Abstract: The present invention provides a method for improving the quality of soy sauce using Bacillus amyloliquefaciens, which relates to the field of microbiology and food technology. The method comprises inoculating Bacillus amyloliquefaciens BBE JY06 during soy sauce fermentation. With Bacillus amyloliquefaciens addition during soy sauce fermentation, the aroma and tastes of soy sauce is improved and the ethyl carbamate content in soy sauce is decreased as well.

  • Patent number: 9961925
    Abstract: The present invention provides a method for reducing EC precursor, citrulline, in soy sauce by inoculating T. halophilus BBE R23 during soy sauce fermentation. Compared to the control, citrulline and EC in soy sauce prepared with T. halophilus BBE R23 is decreased by 86% and 50%, respectively. Addition of 106 CFU/mL T. halophilus BBE R23 also increases volatile flavoring compounds and free fatty acids concentration in the soy sauce product. The present invention provides a method of making soy sauce that not only reduces accumulation of EC precursor citrulline but also improves soy sauce flavor.
