  • Publication number: 20240156847
    Abstract: Use of baicalin in preparation of a medicament for resisting pseudorabies virus (PRV) and diseases caused thereby is provided. The present disclosure relates to the technical field of medicine. It is found for the first time in the present disclosure that the baicalin has anti-PRV activity, has no obvious toxicity to cells in the using concentration range of 31.25-125 ?M, and shows an obvious inhibitory effect on PRV replication and proliferation in the concentration range of 62.5-125 ?M. It can be foreseen that the baicalin can be developed as a safe and effective anti-PRV medicament, and a novel anti-PRV medicament under existing application conditions of the baicalin, with an excellent application prospect.

  • Patent number: 11840582
    Abstract: The present disclosure relates to a method of synthesizing cyclosporine derivatives. The method includes: providing a precursor fluid of the cyclosporine derivative, an alkaline fluid and a ClCH2OCOCl solution; premixing the precursor fluid and the alkaline fluid to obtain a premixed solution; feeding the premixed solution into a first reaction chamber, reacting to prepare a first reaction liquid; feeding the first reaction liquid into a second reaction chamber, reacting the first reaction liquid with a CO2 fluid to prepare a second reaction liquid; and reacting the second reaction liquid with the ClCH2OCOCl solution.

  • Patent number: 10505890
    Abstract: An embodiment of the present invention relates to a network access method, system and terminal device, and computer storage medium, the method comprising: providing one or more physical network interfaces on a first terminal device; the first terminal device transmits an address resolution protocol (ARP) request to a second terminal device, the second terminal device being connected to the first terminal device via one of the physical network interfaces; if the first terminal device receives a DHCP discovery packet or a router announcement request within a first pre-set time, then the first terminal device accesses an internal network; if the first terminal device receives a router announcement broadcast within the first pre-set time or did not receive a response within the first preset time, then the first terminal device accesses an external network.
