The in vitro inhibitory activity of Lonidamine on the aerobic glycolysis of normal as well as leukemic lymphocytes has been investigated. The extent of the impairment of lactate production induced by Lonidamine on normal thymus (T)- and bone marrow (B)-derived lymphocytes was found to be dependent on their source of origin, i.e. residing or circulating pool. Among leukemia tested 'null' and B cell leukemias appeared the most affected metabolically by the compound. Administration in vivo of the drug to the patient with B cell chronic leukemia resulted in a decrease of lactate production by leukemic cells comparable to that induced in vitro. These metabolic changes were paralleled in normal, as well as in leukemic cells by ultrastructural lesions, mainly confined to the mitochondrial compartment.

UI MeSH Term Description Entries
D007191 Indazoles A group of heterocyclic aromatic organic compounds consisting of the fusion of BENZENE and PYRAZOLES. Indazole
D007773 Lactates Salts or esters of LACTIC ACID containing the general formula CH3CHOHCOOR.
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D011720 Pyrazoles Azoles of two nitrogens at the 1,2 positions, next to each other, in contrast with IMIDAZOLES in which they are at the 1,3 positions.

D006019 Glycolysis A metabolic process that converts GLUCOSE into two molecules of PYRUVIC ACID through a series of enzymatic reactions. Energy generated by this process is conserved in two molecules of ATP. Glycolysis is the universal catabolic pathway for glucose, free glucose, or glucose derived from complex CARBOHYDRATES, such as GLYCOGEN and STARCH.
