New non-steroidal estrogen-receptor antagonists, R1 128 A, B, C and D, were isolated from the cultured broth of Streptomyces sp. No. 1 128 by solvent extraction, silica gel chromatography, reverse phase chromatography and preparative HPLC. These compounds inhibited estrogen binding to its receptor. The IC50 values of R1 128 A, B, C and D for partially purified rat uterine cytosol receptor were ...
Ion pair reverse-phase liquid chromatography has been widely employed for nucleic acid separations. A wide range of alternative stationary phases have been utilised in conjunction with ion pair reverse-phase chromatography, including totally porous particles, non-porous particles, macroporous particles and monolithic stationary phases. In this study we have utilised superficially porous silica ...
