ABCB1 selectively to cancer cells. Although the precise mechanism of these compounds is not yet clear, several very different mechanisms have been proposed, but plausible. K these ZSTK474 means can do with the PI3-kinase PKB st Ren turn affects downstream Rts intracellular Ren pathways and apoptosis in cells or MDR YOU CAN apoptosis by increased Hte induce production of ROS in MDR cells. It is possible to change that various compounds of different mechanisms to achieve the same result. CONCLUSION ABC transporters protect the vital functions of the K Rpers Shuizhengguanli compounds, but its overexpression in cancer cells, there grew an obstacle to cancer treatment. It is the leading cause of treatment failure in cancer patients.
Based on the clinical effects of tuberculosis, investigators continue to search for a safe, yet effective inhibitor of this transporter. R788 Although some success has been observed in vitro, to date, these results were not translated into the clinic. A new wave of toxic compounds POWERFUL Hige guarantee MDR cells k Can be used to treat the long-sought MDR in cancer chemotherapy. Through advances in amplification Ndnis the molecular pharmacology of these compounds, in particular their impact on the signaling pathways of the success of the in vivo inhibition of TB can SOON T materialize. Multi-drug resistance is one of the h Common causes of FBK Fill in cancer chemotherapy. MDR may result from the overexpression of ATP-binding cassette transporters such as P-glycoprotein, multidrug resistance protein and protein-best Ndigen breast cancer.
ABC transporter F Promotion of the active efflux of structurally and functionally different amphipathic anticancer drugs of cancer cells that have been entered Dinner decreased intracellular Re accumulation of the drug and is likely to produce a resistance. In fact ABCB1 of MDR1 is the main mediator encodes well characterized and most important of the MDR. The inhibition of ABCB1 as a strategy for MDR in cancer chemotherapy Undo Ngig has been widely studied, but the results are not clear. The current findings, these modulators inhibitors than 1 ranked 3 generations on the basis of their action and interaction with chemotherapeutic agents. The first generation of ABCB1 modulators have been identified as substrates inhibited ABCB1 and fa Competitive on the efflux of various antineoplastic agents ABCB1.
However, high serum concentrations of these compounds were required to MDR obtained in vivo Ht the chance of side effects reverse. The second generation of the ABCB1 modulators showed a pharmacological profile than first generation compounds. For example, k Nnte these agents to reverse MDR in vitro and in vivo. However, they have significantly inhibited CYP3A4, which leads to a reduction in the metabolism of various antineoplastic agents, producing unacceptable toxicity t And dose reduction. Therefore, the second generation of
