  • topotecan
  • A total of 27 anticancer drugs from 1940 to 2010 were obtained from natural sources, for instance actinomycin D, paclitaxel, and vincristine, now one of the most commonly used chemotherapy agents in cancer treatment, while topotecan HCl, dexamethasone, etoposide, and even tamoxifen are mimics of natural products [ 1 ] (Figure 1 ).

  • inhibitor
  • Preferential antitumor effect of the Src inhibitor dasatinib associated with a decreased proportion of aldehyde dehydrogenase 1-positive cells in breast cancer cells of the basal B subtype. (nih.gov)
  • chemotherapy drugs
  • Because of the effect on immune cells (especially lymphocytes), chemotherapy drugs often find use in a host of diseases that result from harmful overactivity of the immune system against self (so-called autoimmunity). (wikipedia.org)
  • respectively
  • The combination index of IC50 was 0.3 or 0.4 in the MDA-MB-231 or MDA-MB-157 cell line, respectively, that is, Eto additively enhanced the antitumor effect of dasatinib in these cell lines (Figures 6 and 7). (nih.gov)
  • Tumor
  • Etoposide is still considered a potent, well-tolerated combination partner in innumerable hematologic and solid tumor treatment schedules, including those for malignant lymphomas and lung cancer. (wikipedia.org)
  • importantly
  • Importantly, the use of drugs (whether chemotherapy, hormonal therapy or targeted therapy) constitutes systemic therapy for cancer in that they are introduced into the blood stream and are therefore in principle able to address cancer at any anatomic location in the body. (wikipedia.org)
  • human
  • Natural health products (NHPs) and natural products (NPs) play a leading role in the discovery and the development of drugs for the treatment of human diseases. (hindawi.com)
  • involves
  • Modern drug discovery is thus usually a capital-intensive process that involves large investments by pharmaceutical industry corporations as well as national governments (who provide grants and loan guarantees). (wikipedia.org)
  • Discovering drugs that may be a commercial success, or a public health success, involves a complex interaction between investors, industry, academia, patent laws, regulatory exclusivity, marketing and the need to balance secrecy with communication. (wikipedia.org)
  • Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim to prolong life or to reduce symptoms (palliative chemotherapy). (wikipedia.org)
  • Combination chemotherapy involves treating a patient with a number of different drugs simultaneously. (wikipedia.org)
  • effects
  • In addition, chemotherapy could result in severe side effects on the CNS and peripheral nervous system (PNS) of cancer patients, and a growing body of evidence demonstrates the involvement of ROS in drug-induced neurotoxicities as well. (mdpi.com)
  • Many of the side effects of chemotherapy can be traced to damage to normal cells that divide rapidly and are thus sensitive to anti-mitotic drugs: cells in the bone marrow, digestive tract and hair follicles. (wikipedia.org)
  • active
  • Historically, drugs were discovered through identifying the active ingredient from traditional remedies or by serendipitous discovery. (wikipedia.org)
  • products
  • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. (rxlist.com)
  • product
  • The drug product is a sterile, white to off-white, lyophilized powder intended for intravenous administration following reconstitution with a diluent. (rxlist.com)
  • The "final product" of drug discovery is a patent on the potential drug. (wikipedia.org)
  • lines
  • Dasatinib decreased the expression levels of phosphorylated Src in all cell lines.Interestingly, dasatinib significantly decreased the proportion of ALDH1-positive cells in the basal B cell lines but not in the other cell lines.A combined use of dasatinib with etoposide additively inhibits their growth.
