IN 1914, Werner1 described the resolution into optically active forms of dodecammine-hexol-tetra-cobaltic hexabromide, [Co[(HO)2Co(NH3)4]3]Br6. This has remained until recently the only example of an inorganic (that is, carbon-free) salt the molecular dissymmetry of which has been proved by optical resolution. A second optically active inorganic salt, which, although also of the ‘complex’ type, is of much simpler composition than Werner's salt, has now been obtained.

Understanding the nature of the consequent pathogenic autoantibodies may provide opportunities for preventing their effects, and data has been drawn together from murine models and human diseases to illustrate the molecular features of autoantIBodies. Expand
