The humanized monoclonal antibodies and the antibody drug conjugates targeting CD276 (B7-H3), derived from the murine monoclonal antibody clone 8H9. These antibodies and the antibody drug conjugates exhibit high affinity and specificity for human CD276, a member of the B7 family of immune regulatory proteins, which is overexpressed in various tumors and involved in immune checkpoint modulation. The humanized antibodies and the antibody drug conjugates are applied for targeted treatment of cancers and refractory diseases.

The invention relates to the technical field of medicines, and particularly discloses application of ipropam in preparation of a medicine for treating immune thrombocytopenic purpura. Aiming at the clinical problem that the condition of a patient with refractory recurrent immune thrombotic thrombocytopenic purpura (iTTP) still progresses after the treatment of plasma exchange combined with hormone, repatumab and immune globulin is invalid, the complement abnormal activation marker of the patient is detected to be increased, which indicates that the complement bypass way participates in disease recurrence refractory; ipropam is combined with plasma exchange, hormone and rituximab for treatment. Results show that the hemoglobin and platelet count is significantly increased after treatment for 5 days, mental symptoms are improved in 9 days, creatinine returns to normal in 11 days, ADAMTS13 activity is less than 0.2 IU / dL in 14 days, an inhibitor turns negative, and ADAMTS13 activity, hemoglobin and platelet return to normal in the fifth week. According to the application, it is proved for the first time that ipropam can effectively reverse the pathological process of refractory iTTP by inhibiting complement bypass pathway activation, and a new treatment strategy is provided for the disease.

The application discloses a kind of PROTAC molecules with crizotinib as target head, preparation method and application, belong to the field of biological medicine;Preparation method includes: chloro carboxylic acid, thionyl chloride and anhydrous DMF are mixed, after heating reflux reaction, remove thionyl chloride, obtain acyl chloride;Pomalidomide, acyl chloride, organic solvent are mixed and reacted, then filtered to obtain intermediate M;Intermediate M, crizotinib, Na2CO3 are mixed and reacted, then filtered to obtain the PROTAC molecule with crizotinib as target head.The in vitro biological evaluation shows that the new PROTAC molecule can efficiently and selectively induce ubiquitination and degradation of target protein, and exhibits significant antiproliferative activity in drug-resistant tumor cell models and animal models;The application proves that the PROTAC molecule has great potential in overcoming drug resistance of traditional inhibitors, and provides a promising lead compound for developing new therapies for treating refractory diseases such as cancer.

The application relates to the field of traditional Chinese medicines, in particular to a traditional Chinese medicine composition for treating IgA nephropathy, which is prepared from the following raw medicinal materials in parts by weight: radix codonopsis 9-15 parts, radix astragali 9-15 parts, zingiberis rhizoma 6-9 parts, rhizoma pinelliae praeparatum 9-15 parts, radix scrophulariae 6-9 parts, rhizoma coptidis 3-6 parts, coix lacryma-jobi 15-45 parts, pyrrosia 9-15 parts, euonymus alatus 9-15 parts and licorice 3-9 parts. The application also includes the application of the traditional Chinese medicine composition in the preparation of medicines for treating IgA nephropathy. The application ingeniously applies the modern intractable disease to the formula, embodies the treatment principle of treating different diseases in the same way, the selected raw medicinal materials meet the compatibility principle of monarch, minister, assistant and messenger, have the effect of treating the principal and secondary symptoms at the same time, and the application effect is remarkable. The application provides a new treatment scheme for patients with IgA nephropathy, improves the survival rate of the patients, and has a good application prospect.

An antibody-drug conjugate comprising two or more functional small molecules for enhancing targeted treatment of cancers and refractory diseases, and methods for preparing such conjugates and pharmaceutical compositions thereof.
