The invention belongs to the technical field of medicine, particularly relates to a heterocyclic nitrogen compound which acts as a tyrosinekinase inhibitor and is represented by a general formula (I) as well as a deuterated material, pharmaceutically acceptable salt or stereisomer thereof. In the general formula (I), X, W, R1, R2, R3, L1, L2, a, b, c, d, e, p, q, a ring A and a ring B are defined in specification. The invention further relates to a preparation method of the compounds, a pharmaceutic preparation containing the compounds, and important actions of the compounds in treatment of leukemia (such as B cell chronic lymphocytic carcinoma and non-hodgkin lymphoma) related to B cell, and autoimmune diseases (such as rheumatoid arthritis and systemic lupus erythematosus).
The invention discloses an antibody-coupled drug as well as a preparation and the application thereof. The antibody-coupled drug is obtained from a heresy-base bifunctional-group polyethylene glycol covalent coupled drug molecule and a Fab' fragment, wherein the structure of the antibody-coupled drug is shown in formula I: Fab'-heresy base bifunctional group polyethylene glycol-drug molecule (1), wherein the Fab' is a fragment of an anti-CD20 antibody and the drug molecule is a cytotoxic drug molecule. According to the antibody-coupled drug, the F(ab')2 fragment degraded from the anti-CD20 antibody is reduced to a Fab' fragment of which the hinge area comprises two free thiols; and the Fab' fragment is then covalently coupled with the drug molecule by the heresy-base bifunctional-group polyethylene glycol, so that the antibody-coupled drug is obtained. The antibody-coupled drug prepared by the invention has the characteristics of fixed drug loading ratio and clear drug loading site structure; the antibody-coupled drug also retains the binding capacity of the anti-CD20 antibody to CD20 proteins, so that the antibody-coupled drug has targeting ability to the CD20-positive cells and is applicable to treatment of non-Hodgkin lymphomas.
The invention discloses a CD 30-targeting replication-defective recombinant lentivirus CAR-T transgenic vector. The CD 30-targeting replication-defective recombinant lentivirus CAR-T transgenic vector comprises a prokaryotic replicor pUC Ori sequence used for plasmid duplication; an ampicillin resistance gene AmpR sequence used for amplification of a large number of target strains; a virus replicor SV40 Ori sequence used for enhancing the replication in eukaryocytes; a lentivirus packaging cis element used for lentivirus packaging; ZsGreen 1 green fluorescent protein used for green fluorescence expression of the eukaryocytes; an IRES ribosome binding sequence used for co-transcription and co-expression of protein; a human EF1 alpha promoter used for eukaryotic transcription of genes of a chimeric antigenacceptor; the chimeric antigenacceptor used for forming second-generation CAR or third-generation CAR integrating recognition, delivery and promoting; and an eWPRE element used for enhancing the expression efficiency of transgenes. In addition, the invention further discloses a construction method and applications of the vector. With the vector, the secretion of the cell factors and the in-vitro lethal effect of the CAR-T cells can be obviously improved, and the effect in treating hodgkin lymphoma or non-hodgkin lymphoma clinically is outstanding.
The invention provides benzothiazine and benzothiadiazine compounds as well as analogues, pharmaceutically acceptable salts, stereoisomers and solvates of the compounds having a structure shown in a general formula a. Repeated experiments prove that the compounds have an inhibition action on PI3Kdelta, wherein most compounds selectively have a remarkableinhibition action on PI3Kdelta, the compounds can be applied to preparation of anti-inflammation and anti-tumor drugs, the range of involved tumor and inflammatory diseases is wide, and the compounds particularly have a better inhibition effect on FL (follicular B-cell non-Hodgkin lymphoma) relapsing in a treatment period, recurrent CLL (chronic lymphocytic leukemia) and recurrent SLL (small lymphocytic lymphoma). Prepared drugs can be combined with other anti-tumor drugs for use and have an obvious effect, and novel treatment drugs are provided for clinically resisting tumors and inflammation diseases.
