2D Structure
Description

Systemic eradicant cereal fungicide Tridemorph is a fungicide. It was developed in the 1960s by the German multinational BASF who sell tridemorph under the trade name Calixin. It is used to control the fungus Erysiphe graminis in cereals, Mycosphaerella species in bananas, and Caticum solmonicolor in tea. Tridemorph is applied onto many crops across the world, but very little data on usage and production is in the public domain. In high doses it has been shown to have teratogenic effects. These effect are manifested in edemas, hemorrhages, hematomas, abnormal development of the brain (hydrocephalia), visceral cranium (micrognathia, cleft palate) and genitourinary system (hydronephrosis), in decreased size of pelvic bones, shoulder girdle, front and hind limbs, etc. (A7934)

Tridemorph belongs to the family of Oxazinanes. These are compounds containing an oxazinane moiety, which consists of a saturated aliphatic six-member ring with one oxygen atom, a nitrogen atom, and four carbon atoms. Isomers of oxaphospholane include 1,2-oxazinane, 1,3-oxazinane, and 1,4-oxazinane.

Targets

General Function:
Zinc ion binding
Specific Function:
Nuclear receptor that binds and is activated by variety of endogenous and xenobiotic compounds. Transcription factor that activates the transcription of multiple genes involved in the metabolism and secretion of potentially harmful xenobiotics, drugs and endogenous compounds. Activated by the antibiotic rifampicin and various plant metabolites, such as hyperforin, guggulipid, colupulone, and isoflavones. Response to specific ligands is species-specific. Activated by naturally occurring steroids, such as pregnenolone and progesterone. Binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes.
