diaziquone profile

Diaziquone is an experimental anticancer drug that acts as an alkylating agent. It was initially synthesized in the 1970s and has shown promising activity against a variety of cancers, particularly leukemia. Diaziquone works by binding to DNA and preventing its replication, leading to cell death. Research on diaziquone has focused on its potential to treat refractory leukemia and other hematological malignancies. While it showed early promise, clinical trials were ultimately discontinued due to its significant side effects, such as bone marrow suppression and neurotoxicity. Despite its discontinued clinical development, diaziquone continues to be studied in preclinical settings for its potential use in combination therapies or in new drug formulations that mitigate its toxicity.'

Role	Description
antineoplastic agent	A substance that inhibits or prevents the proliferation of neoplasms.
alkylating agent	Highly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.

quinacrine Quinacrine: An acridine derivative formerly widely used as an antimalarial but superseded by chloroquine in recent years. It has also been used as an anthelmintic and in the treatment of giardiasis and malignant effusions. It is used in cell biological experiments as an inhibitor of phospholipase A2.. quinacrine : A member of the class of acridines that is acridine substituted by a chloro group at position 6, a methoxy group at position 2 and a [5-(diethylamino)pentan-2-yl]nitrilo group at position 9.	2.04	1	0	acridines; aromatic ether; organochlorine compound; tertiary amino compound	antimalarial; EC 1.8.1.12 (trypanothione-disulfide reductase) inhibitor

Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.	10.36	39	7
Ependymoma Glioma derived from EPENDYMOGLIAL CELLS that tend to present as malignant intracranial tumors in children and as benign intraspinal neoplasms in adults.
