Abstract: The present invention provides use of berbamine dihydrochloride in preparation of an Ebola virus inhibitor. In the present invention, the primed glycoprotein of the Ebola virus (EBOV-GPcl) is taken as a target site, and an antiviral active compound with the capability of binding to the EBOV-GPcl, i.e., berbamine dihydrochloride, is obtained through structure-based virtual screening. Berbamine dihydrochloride can specifically inhibit the entry of an Ebola recombinant virus by binding to the target protein EBOV-GPcl, thereby achieving the effect of anti-Ebola virus infection. The half-maximum effect concentration (EC50) of berbamine dihydrochloride against EBOV is 0.49 ?M, which indicates that berbamine dihydrochloride has a strong inhibition effect on EBOV.

Abstract: The present invention belongs to the technical field of protein and genetic engineering, and specifically discloses use of an erythropoietin human hepatocyte receptor B4 as a target in screening and preparing a biological formulation or medicament for increasing sensitivity to insulin. Also disclosed is use of an erythropoietin human hepatocyte receptor B4 in preparing an insulin-sensitized mouse model. On the basis of insulin signal regulation, a protein EphB4 capable of interacting with an insulin receptor (InsR) is found. The protein can interact with InsR, and insulin stimulation can promote the interaction between the two, which provides a basis for insulin resistance in the case of hyperinsulinaemia. Over-expression of EphB4 can promote degradation of InsR. Inhibition of EphB4 can enhance the sensitivity to insulin and improve insulin resistance.
