We have investigated the interaction of thimerosal, a widely used antiseptic and preservative, with the human erythrocytic GST T1 (glutathione-S-transferase T1). This detoxifying enzyme is expressed in the erythrocytes of solely the human species and it displays a genetic polymorphism. Due to this polymorphism about 25% of the individuals of the caucasian(More)
Conjugation of DNA with testosterone and it aliphatic dimer (alip) and aromatic dimer (arom) was investigated in aqueous solution at pH 7.4. Multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling were used to characterize steroid-DNA binding and DNA morphology. Spectroscopic analysis showed that testosterone binds DNA(More)
The encapsulation of testosterone and it aliphatic dimer (alip) and aromatic dimer (arom) with milk β-lactoglobulin (β-LG) was studied in aqueous solution at pH 7.4. Multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling were used to characterize testosterone-β-LG binding and protein aggregation process. Spectroscopic(More)
Due to the poor solubility of steroids in aqueous solution, delivery of these biomaterials is of major biomedical importance. We have reviewed the conjugation of testosterone and it aliphatic dimer and aromatic dimer with several carrier proteins, human serum albumin (HSA), bovine serum albumin (BSA) and milk beta-lactoglobulin (b-LG) in aqueous solution at(More)
The morphology of tRNA was studied upon conjugation with testosterone and its aliphatic and aromatic dimers, using multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling. Structural analysis showed that testosterone binds tRNA through A62, A64, C60, C61, C63, G51, U50 and U59 bases. The binding affinity was(More)
A series of 7α-linked testosterone dimers were made and tested for biological activity on both androgen-dependent (LNCaP) and androgen-independent (DU-145 and PC3) prostate cancer cell lines. The synthesis proceeds through the formation of a trans-4-(17β-acetoxy-4-androsten-3-one-7α-yl)-but-2-enoic acid 4-hydroxy-alkyl ester intermediate of various length(More)
A substantial part of steroids is bound to serum proteins in vivo. We report the association of testosterone and it aliphatic dimer (alip) and aromatic dimer (arom) with human serum albumin (HSA) and bovine serum albumin (BSA) in aqueous solution at physiological pH. Multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular(More)
