Benzoyl urea derivatives that are alpha helical peptides mimetics that mimic BH3-only proteins, compositions containing them, their conjugation to cell-targeting-moieties, and their use in the regulation of cell death are disclosed. The benzoyl urea derivatives are capable of binding to and neutralizing pro-survival Bcl-2 proteins. Use of benzoyl urea derivatives in the treatment and/or prophylaxis of diseases or conditions associated with deregulation of cell death are also described.

A practical route to the labile tetracyclic isoxazolo[4,3,2-de]phenanthridinone moiety of the antifungal parnafungins has been developed. Zinc reduction of a methyl 2'-hydroxymethyl-2-nitro-3-biphenylcarboxylate, which was prepared by a Suzuki coupling, afforded a benzisoxazolone that was treated with MsCl and base to generate the labile tetracyclic ring system in 37-47% yield. This compound decomposes to the phenanthridine in CDCl3 and the phenanthridine N-oxide in aqueous base.
