Collateral drug sensitivity induced in CPT-11 (a novel derivative of camptothecin)-resistant cell lines. 1990

Division of Hematology and Chemotherapy, Chiba Cancer Center Hospital, Japan.

Collateral drug sensitivity was induced in CPT-11-resistant cell lines (CPT-K and T). Ten of the 19 kinds of antineoplastic agents (especially, 5 of 6 kinds of DNA topoisomerase II inhibiting agents) were effective in inducing collateral drug sensitivity. Alteration of DNA topoisomerase I seemed to be unrelated to acquisition of multidrug resistance.

UI	MeSH Term	Description	Entries
D002166	Camptothecin	An alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA TOPOISOMERASES, TYPE I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity.	Camptothecine
D004351	Drug Resistance	Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.	Resistance, Drug
D004354	Drug Screening Assays, Antitumor	Methods of investigating the effectiveness of anticancer cytotoxic drugs and biologic inhibitors. These include in vitro cell-kill models and cytostatic dye exclusion tests as well as in vivo measurement of tumor growth parameters in laboratory animals.

D000077146	Irinotecan	A semisynthetic camptothecin derivative that inhibits DNA TOPOISOMERASE I to prevent nucleic acid synthesis during S PHASE. It is used as an antineoplastic agent for the treatment of COLORECTAL NEOPLASMS and PANCREATIC NEOPLASMS.	7-Ethyl-10-hydroxycamptothecin,CPT 11,CPT-11,Camptosar,Camptothecin-11,Irinotecan Hydrochloride,Irrinotecan,NK012 Compound,SN 38,SN 38 11,SN-38,SN-38-11,7 Ethyl 10 hydroxycamptothecin,CPT11,Camptothecin 11,SN3811

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D054198	Precursor Cell Lymphoblastic Leukemia-Lymphoma	A neoplasm characterized by abnormalities of the lymphoid cell precursors leading to excessive lymphoblasts in the marrow and other organs. It is the most common cancer in children and accounts for the vast majority of all childhood leukemias.
