Optimization of 1H-tetrazole-1-alkanenitriles as potent orally bioavailable growth hormone secretagogues

Bioorg Med Chem Lett. 2008 Mar 15;18(6):2067-72. doi: 10.1016/j.bmcl.2008.01.100. Epub 2008 Jan 31.

Abstract

1H-tetrazole-1-alkanenitrile SR-9g exhibits a >10-fold in vivo potency enhancement over the lead nitrile 1 and has acceptable oral bioavailability in rats and dogs. An enantiospecific synthesis of 1H-tetrazole-1-alkanenitrile nitriles 9 has been developed.
