The present invention relates to the design, synthesis, and the peptidyl-prolyl isomerase (PPIase or rotamase) inhibitory activity of novel bicyclic diamide compounds that are neuroprotective and/or neurotrophic agents (i.e. compounds capable of stimulating growth or proliferation of nervous tissue) and that bind to immunophilins such as FKBP12 and inhibit their rotamase activity. This invention also relates to pharmaceutical compositions comprising these compounds.

Pyrrole Butyric Acid Derivatives as Inhibitors of Steroid 5.ALPHA.-Reductase.
A series of pyrrole butyric acid derivatives was synthesized and evaluated for inhibitory activity on human and rat steroid 5α-reductase in vitro and ex vivo. 3-Benzoyl-4-alkylpyrrole-1-butyric acids and 1-methyl-2-alkyl-3-benzoylpyrrole-5-butyric acid derivatives were effective inhibitors. Structure activity relationships were evaluated among the 37 compounds synthesized. Compound 37 (HQL-1069) shows potent inhibitory activities against both rat and human 5α-reductase.
