The mitoxantrone hydrochloride liposome can effectively treat urothelial cancer, breast cancer, and bone and soft tissue sarcoma, and compared with common mitoxantrone hydrochloride injections, the mitoxantrone hydrochloride liposome has better therapeutic effect and fewer adverse reactions.

Abstract: The present invention provides use of mitoxantrone hydrochloride liposome and pegaspargase in preparation of drug for treating NK/T-cell lymphoma (NKTCL). The NKTCL comprises initial-treating, relapsed, and refractory extranodal NKTCL. Preferably, the initial-treating, relapsed, and refractory extranodal NKTCL is initial-treating, relapsed, and refractory extranodal nasal NKTCL. On this basis, other first-line and second-line drugs for treating NKTCL can also be further used. The present invention further provides a method for treating NKTCL. The method relates to administering therapeutically effective amounts of mitoxantrone hydrochloride liposome and pegaspargase to a patient. The mitoxantrone hydrochloride liposome improves the curative effect of pegaspargase on NKTCL, has little toxic and side effects, and increases the complete response rate (CR rate) and the partial response rate (PR rate) of diseases.

Abstract: Provided in the present invention are a salt of an arylaminopurine derivative represented by Formula (2), a preparation method therefor and the use thereof. The salt obtained in the present invention has good crystallinity and significantly improved solubility relative to that in the free form, and the preferred salt and crystal form have low hygroscopicity and can exist stably. Therefore, compared with the free form of arylaminopurine derivatives or other salts, it is easier to prepare same into a medicine.

Abstract: Disclosed is a compound as shown in formula (I) or a pharmaceutically acceptable salt, a stereoisomer, an isotope derivative or a prodrug thereof. The compound has an excellent activity as a cyclin-dependent kinase 9 (CDK9) inhibitor for treating hyperproliferative diseases. The experimental research on in vitro inhibition of cell proliferation and in vivo suppression of tumors shows that such compounds have a relatively strong inhibitory effect on MV4;11 cells and in vivo tumor models, and have a good selectivity and a low toxicity and few side effects, thereby possessing a good clinical value as novel anti-tumor drugs.

Abstract: Disclosed is a use of a liposomal pharmaceutical preparation of mitoxantrone in the preparation of a medicament for treating lymphoma, wherein the lymphoma is preferably non-Hodgkin's lymphoma, further preferably aggressive non-Hodgkin's lymphoma, more preferably diffuse large B-cell lymphoma or peripheral T-cell lymphoma, and more further preferably relapsed or refractory diffuse large B-cell lymphoma or peripheral T-cell lymphoma. The mitoxantrone liposomes are used as single anti-tumor therapeutic agent without being combined with other anti-tumor agents.

Abstract: The present invention provides use of a multi-target protein kinase inhibitor compound A or a pharmaceutically acceptable salt thereof in the manufacture of a medicament for treating leukemia, and provides a method for treating acute myeloid leukemia, especially acute myeloid leukemia with FLT3 mutation, with compound A. In clinical trials, compound A has certain efficacies both on acute myeloid leukemia with FLT3-ITD mutation and/or FLT3-TKD mutation, and on DEK-CAN positive acute myeloid leukemia with FLT3-ITD mutation. Patients with relapsed and/or refractory acute myeloid leukemia who have failed treatment previously with Type II FLT3 inhibitors (e.g., sorafenib) can still clinically benefit from the treatment with compound A.

Abstract: The present invention relates to the field of genetic engineering drugs, particularly to a novel B cell activating factor (BAFF) antagonist and use thereof. The technical problem to be solved by the invention is to find a new and effective selection for the prevention and treatment of autoimmune diseases. The B cell activating factor receptor antagonist is mainly obtained by the fusion of the domain 2 binding BAFF in TACI receptor and the domain binding BAFF in Br3 receptor, and it also can be fused with a Fc segment of IgG1 to obtain a new fusion protein molecule. Experiments indicate that said new fusion protein molecule has the function of BAFF antagonist, which can treat the autoimmune diseases, and supply a new and effective selection for the prevention and treatment of the autoimmune diseases.
