Enantomerically purified phenothiazines are provided as active ingredients of medicaments to limit activity of bone resorbing cells so as to reduce bone loss. Novel phenothiazine derivatives are provided. A method of synthesizing enantiomerically pure phenothiazine derivatives is provided that avoids post-synthetic enantiomeric resolution.
