Construction of the highly strained CDEF parent tetracycle, a structural motif found only in the potent ectoparasiticidal agents (+)-nodulisporic acids A and B and related congeners, has been achieved via a new modular indole synthesis, exploiting a sequential Stille cross-coupling/Buchwald-Hartwig union/cyclization tactic. The new indole synthesis holds the promise of rapid assembly of diverse, highly substituted indoles possessing uncommon substitution patterns.

This invention provides peptides that act as selective NPY2 receptor agonists in vitro and are efficacious in vivo to reduce food intake. The invention is a peptide selected from a specific group of derivatized NPY-related peptides, or functional equivalents thereof. The invention is also directed to a method of treating a metabolic disease in a mammal comprising administering a therapeutically effective amount of the peptides to said mammal to reduce food intake and body weight.

A second-generationstrategy for construction of (+)-nodulisporic acids A and B based on the development of a new, effective modular indolesynthesis exploiting a sequential Stille cross-coupling/Buchwald−Hartwig union/cyclization tactic is disclosed. This strategy evolved due to the considerable acid instability of the C(24) hydroxyl group observed in several advanced intermediates during our first-generation
