The present disclosure relates to a crystal form of a pyridopyrimidine derivative and a preparation method thereof, and specifically relates to the crystal form of the compound of formula (I) and a preparation method thereof. The new crystal form has good physical and chemical properties, thereby facilitating clinical treatments.

##STR00001##

The present invention discloses a preparation method for a disubstituted PEGylated interleukin 2, which comprises the steps of: (1) PEGylating IL-2 to obtain a crude product of a PEGylated interleukin; (2) performing gel chromatography filtration to remove free interleukin 2 from the crude product; (3) performing affinity chromatography on the product in the step (2) by means of an α receptor column, and collecting a flow-through peak component and an elution peak component; (4) performing ion exchange separation on the flow-through peak component and the elution peak component in the step (3); and (5) collecting components of the disubstituted PEGylated interleukin 2.

A natural immune agonist complex, consisting of an immune agonist and a targeted liposome, where the immune agonist is M(cGAMP)L.sub.n. The targeted liposome is formed by a nanobody targeting a tumor microenvironment, a cell membrane-targeted penetrating peptide, or a blood-brain barrier-targeted penetrating peptide with a liposome through chemical bonding. This application further provides a preparation and application of the natural immune agonist complex.

Provided are multi-specific antigen binding molecules, including bispecific antibodies, that bind to CD3 and an HIV antigen, including HIV envelope protein gp120. Also provided are methods of using such antigen binding molecules to treat or prevent HIV infection.
