(±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane (BMC) is a cyclohexane with two mercaptoacetamido groups. It is used, both in vitro and in vivo, to promote the correct folding of proteins that require disulfide bonds for functionality. For in vitro applications, BMC may be used to facilitate protein refolding of solubilized proteins from inclusion bodies. Reducing agents, like dithiothreitol, may interfere with refolding. BMC may also be added to the growth medium of cells, including yeast cells, to enhance the folding of proteins with disulfide bonds in vivo.
5-trans-17-phenyl trinor Prostaglandin F2α (5-trans-17-phenyl trinor PGF2α) represents the 5-trans isomer and the free acid variant of 17-phenyl trinor PGF2α, distinct from its ethyl amide and dimethyl amide derivatives. This compound serves as a potential impurity in 17-phenyl trinor PGF2α formulations. It is utilized as an analytical standard for the detection and quantification of itself in 17-phenyl trinor PGF2α preparations.
All-trans-13,14-Dihydroretinol, a metabolite of all-trans-retinoic acid, is synthesized through the enzymatic action of retinol saturase on all-trans-retinoic acid.
