A couple of additional experiments involving TMA-2 had been set up and started, but somehow never had enough fire to get completed. Studies on the optical isomers had gotten up to assays of 6 milligrams on each of the separate isomers, but had never been taken higher. The R isomer is much the more potent in rabbit assays, but the human comparisons remain unknown at present. Also, a study of the 14C labeled racemate (5 microcuries in 40 milligrams) was conducted with a view to metabolite analysis, but again, the project was abandoned before any results were obtained. In the rat, the 4-methoxyl carbon appeared as expired carbon dioxide to the extent of about 20%. And this is some four times the amount seen from either of the other two methoxyl carbon atoms.
