Gossypol is a natural phenol compound derived from cotton stems, leaves, seeds, and flower buds.Gossypol has a 518.55 Dalton molecular weight and a yellow pigment. The most common toxic effectof Gossypolis the impairment of male and female reproduction. Another important toxic effect is its interference with immune function, reducing an animal’s resistance to infections and impairing the efficiency of vaccines.
In vitro: In bovine granulosa cells, treatment with gossypol dose-dependently decreased hCG-induced cAMP formation. Gossypol (12.5 μg/ml) inhibited basal cAMP level and progesterone secretion(2). Gossypol (50 and 100 μg/ml) decreased the percentage of sperm that completed the swim-up procedure. When cultured with5 or 10 μg/ml gossypol, development of cleaved embryos was reduced(3). In the lymphocytes isolated from lymph nodes of BALB/c mice, gossypol significantly inhibited the proliferation of mouse lymphocytes stimulated with phorbol ester plus ionomycin in a dose-dependent manner. Gossypol significantly suppressed the lymphoblastic transformation of both T and B lymphocyte subsets. Moreover, gossypol could induce apoptosis of lymphocytes in a time- and dose-dependent manner (4).
In vivo: In male Sprague-Dawley rats, gossypol (25 mg/kg, i.p.) caused marked changes in the activity of the hepatic and serum γ-glutamyltransferase (GGT) and microsomal monooxygenases (5). Rats that received lower gossypol doses (15 mg/kg/day for four weeks or 30 mg/kg/day for two weeks) showed morphological changes in the liver(6).
