The antidiabetic and anticholinergic effects of chrysin on cyclophosphamide-induced multiple organ toxicity in rats: Pharmacological evaluation of some metabolic enzyme activities.

Chrysin (CH) or 5,7-dihydroxyflavone is a flavonoid present in various plants, bee propolis, and honey. Cyclophosphamide (CYP) is a chemotherapeutic drug, which is extensively used in the treatment of multiple human malignancies. In our study, we aimed to investigate the effects of CYP and CH on some metabolic enzymes including carbonic anhydrase, aldose reductase, paraoxonase-1, α-glycosidase, acetylcholinesterase, and butyrylcholinesterase enzyme activities in the brain, heart, testis, liver, and kidney tissues of rats. Thirty-five adult male Wistar rats were used. The animals were pretreated with CH (25 and 50 mg/kg b.w.) for seven days before administering a single dose of CYP (200 mg/kg b.w.) on the seventh day. In all the tissues, the treatment of CH significantly regulated these enzyme activities in CYP-induced rats. These results showed that CH exhibited an ameliorative effect against CYP-induced brain, heart, liver, testis, and kidney toxicity.
