Synthesis and studies on antioxidants: ethoxyquin (EQ) and its derivatives.
In our study ethoxyquin (EQ) and its two complexes with flavonoids were obtained from ethoxyquin (1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline, EQ) and quercetin (EQ-Q, 1:1) or rutin (EQ-R, 1:1). Cytotoxicity of the tested compounds was studied using the trypan blue exclusion method and the properties of the studied compounds were also analyzed with the TUNEL method evaluating their ability to...
متن کاملSome studies on cytisine and its methylated derivatives.
1. In mice cytisine hydrochloride is less toxic intravenously than nicotine hydrogen tartrate, but more toxic by intraperitoneal or oral administration. Compared with cytisine, caulophylline hydrogen iodide is one-fifth to one-tenth as toxic and caulophylline methiodide is less than one-thirtieth as toxic.2. The surprising low oral toxicity of cytisine and nicotine may be ascribed to the method...
متن کاملStudies on pleuromutilin and some of its derivatives.
A number of derivatives of pleuromutilin (I) and of its degradation product, mutilin (II1, was prepared. The new monotosylation product of pleuromutilin (IIIc) served as the key substance for modification of the glycolic acid side chain. From the pleuromutilin monosuccinate (IIIk) water-soluble salts were obtained, among them the crystallized diethylaminoethanol salt that was investigated more ...
متن کامل[Studies on the thyrotropic activity of hCG and its derivatives].
The placenta may be involved in the regulation of the maternal thyroid function during pregnancy. As human chorionic gonadotropin (hCG) is a primary protein from the placenta, we examined the thyrotropic activity of hCG and its derivatives using tissue culture and monolayer cell culture of human thyroid glands. The TSH receptor preparation was made from thyroid tissues, and its binding affinity...
