Tecentriq
Pd-l1 may be expressed on tumor cells and/or tumor infiltrated immune cells and may contribute to the inhibition of anti-tumor immune responses in tumor microenvironment. The binding of pd-l1 to T cells showed that pd-1 and B7.1 receptors and antigen presentation showed that the cells inhibited the activity of cytotoxic T cells, t-cell proliferation and cytokine production. Atjuzumab is a monoclonal antibody that binds to pd-l1 and blocks its interaction with pd-1 and B7.1 receptors. This release of pd-l1 / pd-1 mediated inhibition of immune responses, including activation of anti-tumor immune responses, does not induce antibody dependent cytotoxicity. In the homologous mouse tumor model, inhibition of pd-l1 activity leads to reduced tumor growth.
Tegafur
Tegafur is an anti-tumor drug, also known as furafluorouracil, furfuradine, furfuradine, furyl, Fangke, flufluflurane, furafluorouracil, tetrahydrofuran fluorouracil. It is a derivative of fluorouracil, and has no anti-tumor effect in vitro. After entering the human body, it is released gradually through the liver drug metabolism enzyme and microsomal enzyme P-450 Fluorouracil (5-FU) is produced and plays a cytotoxic role.

Tetrabromobisphenol A Bis(dibromopropyl Ether)
Octabromoether, molecular formula c21h20o2br8, molecular weight 934.26, melting point about 105 ℃, soluble in benzene, acetone, chloroform, etc., insoluble in water hexanol, decomposition temperature 270 ℃, is the main product of further processing of tetrabromobisphenol A, with better flame retardant effect. It belongs to additive flame retardant in polymer flame retardant, and is often used in flame retardant of polypropylene (PP), polyethylene (PE), polybutene and many polyolefin copolymers. Its molecular structure contains aliphatic bromine and aromatic bromine. It has high flame-retardant efficiency, can withstand high processing temperature, can melt blend with polyolefin, and has appropriate thermal stability, low price and efficiency. When comparing the flame-retardant PP with the non flame retardant PP blank sample, it was found that there was almost no difference in mechanical properties between them. In the combustion products of this product, the carcinogens tetrabromodibenzodiane and tetrabromodibenzofuran can hardly be detected. The results show that compared with the traditional flame retardant decabromodiphenyl ether, when it reaches the same flame retardant level, the amount of this product is less. Compared with hexabromocyclododecane, the decomposition temperature is higher, and in some aspects, hexabromocyclododecane can not be replaced. The flame retardant effect of octabromoether is very good, which is one of the development directions of bromine series flame retardants, and its application prospect is very broad.

This product is a non carcinogenic substitute of benzidine-1 (negative for Ames test), which is suitable for peroxidase substrate of enzyme-linked immunosorbent assay. The substrate produces a soluble light blue end product, which can be read at 370 or 620-650nm by spectrophotometry. The TMB reaction can be terminated with 2mh2so4 (turning yellow), and the data can be read at 450nm. A sensitive and specific reagent for the detection of blood, hemoglobin and peroxidase.
Tetramethylthiuram Disulfide
TMTD is a general accelerator for natural rubber and synthetic rubber, and it is widely used as fungicide and seed soaking agent in agriculture.

In addition, the process of using sodium hypochlorite as oxidant and using electrophoresis to synthesize accelerator TMTD has also been reported. The above synthetic methods generally have the disadvantages of high cost of synthetic products. With reference to relevant literature, dimethylamine and carbon disulfide were proposed as raw materials. The process of synthesizing TMTD with hydrogen peroxide as oxidant and water as solvent has achieved high yield (98%) and good product quality (reaching the international first-class product level), and effectively reduced environmental pollution.
