The mouse bone-marrow micronucleus test is one of the most widely used genetic toxicology assays. In this report the results of testing 21 compounds in the micronucleus test are presented. Of the 21 compounds tested, 3 potential chemotherapeutic agents were identified as strongly clastogenic. In addition, one compound was identified as a weak inducer of micronuclei in the assay. Further testing of this compound in an in vivo bone marrow metaphase analysis failed to confirm this material as clastogenic. The remaining 17 compounds were classified as negative in the assay. In general the results of the micronucleus test agreed with the results of other genetic toxicology assays on this group of compounds.

UI	MeSH Term	Description	Entries
D007211	Indoles	Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.
D007555	Isoxazoles	Azoles with an OXYGEN and a NITROGEN next to each other at the 1,2 positions, in contrast to OXAZOLES that have nitrogens at the 1,3 positions.	Isoxazole

D009153	Mutagens	Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.	Clastogen,Clastogens,Genotoxin,Genotoxins,Mutagen
D009621	Nogalamycin	An anthrocycline from a Streptomyces nogalater variant. It is a cytolytic antineoplastic that inhibits DNA-dependent RNA synthesis by binding to DNA.	U-15167,U 15167,U15167
D010879	Piperazines	Compounds that are derived from PIPERAZINE.
D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
