  • Publication number: 20210015094
    Abstract: By determining the lethality rate to Meloidogyne incognita and Caenorhabditis elegans, it was found that the methylmalonic acid has a better nematicidal effect on the Caenorhabditis elegans, with the LC50 being 13.11 and 1.20 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. After compounding the methylmalonic acid with betaine, the LC50 was 2.85 and 0.27 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. Meanwhile, the methylmalonic acid also has an inhibiting effect on Pseudomonas solanacearum and Erwinia carotovora. The preparation of the methylmalonic acid provides a new choice for preparing novel biocontrol agents against the root-knot nematodes.

  • Publication number: 20200369785
    Abstract: IgG epitope and applications thereof as a target are provided. The IgG epitope is the CH1 domain of non-B cell-derived IgG, and there is N-glycosylated sialic acid modification at the Asn162 site of the domain. The realization of its antigen functions must depend on the sialylation of the site. The present invention further discloses the applications of the IgG epitope as a drug target in preparing drugs for diagnosis and/or treatment of epithelial tumors. In addition, our studies showed that this antigen depends on the sialylation of Asn162 site as a drug target, and the sialylation of this site must depend on sialyltransferase ST3GAL4, indicating that the enzyme can be used as a drug target for preparing tumor therapeutic drugs. Further, integrin ?4 is co-expressed and co-localized with IgG containing the epitope. IgG can be used as a marker for preparing drugs for the auxiliary detection of epithelial tumors.
